Ruki Mukami

Possible post-traumatic stress disorder (PTSD)
Psychological
interpretation It is one of the most interesting possibilities when analyzing your character.

Ruki experienced different traumatic events during her childhood:

• The loss of her social position and her home.
• The abandonment of his mother.
• The death of his father.
• Physical abuse by servants.
• Harassment and humiliation in the orphanage.
• The physical punishments and scars they keep.
• The feeling of having no one to protect him.
  These experiences could have left him with deep emotional scars.

Possible manifestations:

• Constant distrust of other people.
• Need to maintain control.
• Difficulty feeling vulnerable.
• Negative reactions to childhood memories.
• Problems establishing relationships based on trust.
• Tendency to hide their emotions.
  Your need to control situations could work as a way to avoid feeling helpless again.

2. Attachment
   problems Psychological interpretation
   Ruki had a childhood in which the people who were supposed to protect him ended up abandoning him or hurting him.

His mother disappeared and his father died when he was still young.

This could profoundly affect their ability to emotionally trust other people.

Possible characteristics:

• Fear of being abandoned.
• Distrust of signs of affection.
• Difficulty becoming emotionally dependent on someone.
• Need to check people's loyalty.
• Tendency to maintain a certain emotional distance.
  One thing is especially important: Ruki retains the memory of his mother, and a part of him seems to be still waiting for her to return.

This shows that, although he tries to be indifferent, there is still a need for affection that he never satisfied.

Possible difficulties regulating emotions
Ruki usually maintains a calm expression even when he is upset.

However, that doesn't mean you experience few emotions.

You may have difficulty recognizing, expressing, and managing feelings such as:

• Sadness.
• Fear.
• Shame.
• Jealousy.
• Impotence.
• Vulnerability.
  Instead of openly expressing what he feels, he often resorts to control, coldness and manipulation.

4. Controlling and manipulative
   personality traits This does not necessarily constitute a disorder.

Ruki has a very strategic personality and uses other people's information, authority, and psychology to achieve her goals.

It can:

• Analyze the weaknesses of others.
• Manipulate situations in their favor.
• Use words to intimidate.
• Hiding their true intentions.
• Maintain a dominant attitude.
• Making decisions without consulting others.
  Their behavior can be interpreted as a combination of their temperament, their traumatic experiences, and their philosophy of life.

Trauma 1. The loss of his family and his social
position When he was little, Ruki belonged to an aristocratic family.

He had a privileged life and was used to receiving special treatment.

However, his family ended up being financially ruined.

One day he discovered that servants were looting his home.

When he tried to stop them, they beat him and revealed that his mother had abandoned the family.

Shortly afterwards he found his father dead.

Possible psychological consequences:

• Sudden loss of security.
• Fear of depending on other people.
• Difficulty accepting that circumstances may change.
• Distrust of those who have power over him.
• Need to regain control.
  There is also an interesting contradiction: during his childhood he had treated other people badly because of their social position, but later he experienced the suffering of being completely helpless.
  Trauma 2. Maternal
  abandonment Her mother is a particularly important figure in her story.

Ruki discovers that she left with another man and left him behind.

Although he received a letter in which she said she loved him, her actions contradicted his words.

This could generate an emotional contradiction:

How can someone say they love me and still abandon me?

Possible consequences:

• Difficulty in believing in declarations of love.
• Distrust of people who are emotionally close.
• Fear that affection is temporary.
• Need to check the intentions of others.

Trauma 3. The death of his father
His father was one of the few important emotional figures of his childhood.

Unlike Ruki, he was a kind and generous person.

His death represented the loss of a security figure.

In addition, Ruki keeps a book that belonged to him.

That object has a sentimental meaning: it represents a connection to a stage of his life that he can no longer recover.
Trauma 4. Abuse at the orphanage
After losing her home, Ruki ended up in an orphanage.

There he was mistreated by both other children and responsible adults.

He was humiliated for having belonged to the aristocracy.

The only children with whom he managed to establish a relationship of trust were Kou, Yuma and Azusa.

The four tried to escape, but were discovered.

Ruki received a punishment that left significant scars on his back.

Possible consequences:

• Hypervigilance.
• Distrust of authority figures.
• Need to protect their siblings.
• Refusal to feel inferior.
• Difficulty tolerating impotence.
• Identification with people they consider vulnerable.
  Trauma 5. To have been treated like cattle
  This event has a special significance.

Ruki was dehumanized and treated as if he had no value of his own.

Subsequently, his behavior towards Yui presents a rather dark contradiction: he himself comes to treat her like cattle.

One possible interpretation is that it reproduces some of the power dynamics it suffered.

That is, he goes from being the one who was completely subdued to becoming the one who has the power to subdue another person.

This does not justify their behavior, but it helps to understand where it may come from.

Weaknesses
Ruki has considerable intelligence, but that doesn't mean he's emotionally invulnerable.
Weakness How it manifests
itself Distrust It is difficult for them to believe in the intentions of others.
Need for control It makes him uncomfortable losing authority over a situation.
Pride You may have a hard time acknowledging your mistakes.
Emotional coldness Hides their feelings behind a calm attitude.
Grudge can hold resentment for a long time.
Rigidity It is difficult for them to accept decisions that they consider irrational.
Manipulation May resort to unethical strategies to achieve goals.
Affective vulnerability: It is difficult for them to recognize how much they need certain people.

Their greatest psychological weakness: the fear of being a helpless and abandoned person again.

Ruki tries to build a life where no one can ever again have so much power over him.

5. Strengths
   Not everything about Ruki is related to her negative experiences. It also has very remarkable qualities.
   Intelligence
   They are extremely observant and have a great ability to analyze situations.
   Responsibility
   He takes his role as an older brother very seriously.
   Leadership
   He is able to organize his siblings and maintain a certain stability within the family.
   Patience
   He does not usually act impulsively. He prefers to analyze before making decisions.
   Perseverance
   He survived very difficult circumstances and managed to build a new life.

Karlheinz took it upon himself to provide him with an education that would allow him to become the brains of the Mukami.
Family
protection Although he may be overbearing, he cares about his siblings and takes responsibility for caring for them.
Self-control
has a great ability to maintain a serene appearance even in complicated situations.

First stage: his human
childhood Ruki was born into an aristocratic family.

During his childhood he was a spoiled and arrogant child who used to treat badly those he considered inferior.

His father was a kind person, although he had difficulty managing the family money.

When the family ended up going bankrupt, Ruki lost practically everything she knew.

His mother abandoned him and his father died.
Second stage: life on the streets
After being left alone, Ruki stayed for a while near his old home waiting for his mother to return.

He eventually ended up on the streets and was subsequently sent to an orphanage.

There she suffered mistreatment and humiliation.
Third stage: he meets his siblings
In the orphanage he met:

• Kou Mukami.
• Yuma Mukami.
• Azusa Mukami.
  The four of them developed a relationship of companionship.

Ruki ended up becoming an important figure for them, especially because of his intelligence.

They tried to escape from the orphanage, but failed.
Stage Four: Karlheinz When the four were in dire straits, Karlheinz
appeared.

He offered them to become vampires and get a new chance at life.

The four accepted.

Karlheinz made Ruki the brains of the group and took it upon himself to provide her with a special education.

Ruki developed a strong feeling of gratitude towards him, although she also understood that there were interests behind his adoption.

• Prefer interesting conversations to superficial ones.
• Maintains a fairly calm expression.
• They are not used to sharing their feelings.

• Likes to set rules.
• Expects others to respect their instructions.
• It can be quite demanding.
• Doesn't easily tolerate disobedience.
• Has difficulty accepting others questioning their decisions.
• You may adopt an intimidating attitude when you lose your patience.
  Their authority is usually manifested not through shouting, but through a firm voice, calculated comments, and an attitude that makes it clear who is directing the situation.

Manipulative and strategic
, Ruki knows how to use other people's information and emotions to get what he wants.

• You can hide your true intentions.
• Knows how to detect insecurities.
• Use words to influence other people.
• It can cause someone to end up questioning their own decisions.
• Prefers to have an advantage before facing someone directly.
  It is important to note that their intelligence is not always accompanied by consideration for the feelings of others.
  Proud
  He has a fairly high image of his intellectual abilities.
• He does not like to make mistakes.
• It is difficult for them to accept that someone is right when they contradict their ideas.
• Can be condescending.
• They can't stand feeling inferior.
• It bothers you to be underestimated.
  However, his pride is also related to his past: he does not want to be treated as insignificant again.

This is one of the most interesting parts of his personality.

Ruki is not an emotionally indifferent person. He has feelings, but he has a hard time expressing them in a healthy and direct way.

When he is sad:

• He tends to close in on himself.
• He prefers not to talk too much about what happens to him.
• They can take refuge in reading or in their activities.

• Remember the actions that you consider unforgivable.
• It can take a long time to trust again.
  When worried:
• Tends to look for practical solutions.
• You can give instructions instead of expressing concern.
• Observe the person carefully.
• Try to prevent any situation that you consider dangerous.
  For example, it would probably be easier to hear him say, "Don't do such recklessness again" than "I was worried about you."

Ruki's social
behavior is not particularly sociable in the conventional sense.
Situation Behavior
With strangers Polite, reserved and observant.
With intelligent people You can show interest and respect.
With impulsive people He is critical and impatient.
With arrogant people You can enter into an intellectual competition.
With vulnerable people He can be protective, although also authoritarian.
With people he considers dishonest Distrustful and calculating.
With people close to him More familiar, although he retains his dominant character.

You don't need to be the center of attention. He prefers to observe, listen and understand how people work.
4. His sense of humor
Although he is not a particularly joking character, he has a rather particular humor.

• Use sarcasm.
• You can make scathing comments.
• He has a certain tendency to make fun of the ignorance of others.
• Their mood is usually dry.
• You can make ironic comments while maintaining a completely serious expression.
  It may take a few seconds for someone to realize that they just pulled a joke.

Ruki has fairly quiet and intellectual tastes.

Likes:

• Reading books.
• Solve puzzles.
• Cooking.
• Acquire knowledge.
• Activities that require concentration.
• Maintain a certain order.
• Have your affairs organized.
• Intellectual conversations.
  He does not like:
• Voluntary ignorance.
• Irresponsibility.
• Disobedience.
• Constantly questioning their authority.
• Chaotic situations.
• People who act without thinking.
• Feeling helpless.

Ruki is the leader of the four Mukami and usually takes on the role of the person in charge.

With his brothers he has a combination of authority, demand and concern.

• Kou: Often criticizes their impulsive behavior and tendency to act carefree. However, he recognizes his capabilities.
• Yuma: their personalities clash quite a bit. Yuma is more impulsive and temperamental, while Ruki is calculating and controlling. They can argue about their different ways of seeing things.
• Azusa: is usually more patient with it. He is aware of his sensitivity and his difficulties, although their relationship also has problematic aspects.
  Ruki can be quite strict, but he considers keeping his siblings together to be an important responsibility.

7. His psychological contradictions
   This is one of the characteristics that most enriches the character.
   What it shows What Independence could hide
   Fear of depending on someone.
   Authority Fear of feeling helpless.
   Coldness Difficulty expressing affection.
   Intelligence Need to demonstrate its value.
   Distrust Fear of being abandoned.
   Protection Fear of losing important people.

1. What would it be like to fall in love?
   Ruki is not someone who falls in love easily.

Before getting emotionally involved, you would probably observe the person for quite some time.

He would look at:

• His way of speaking.
• Their intelligence.
• Your values.
• Your behavior with other people.
• Your ability to hold a conversation.
• Their honesty.
• Their way of solving problems.
  He would be interested in someone who had his own personality and did not just obey him.

When I started to develop feelings, I would probably try to rationalize them.

You might think that you're just curious about the person, that you enjoy their company, or that there's some logical reason to pay so much attention to them.

But I would end up paying more attention to it than I would admit.

An important characteristic: Ruki may be slow to recognize that he is in love, because accepting that someone is emotionally important to him implies accepting a certain vulnerability. Their love language would likely be related to acts of service, attention, and time sharing.
Acts of service

• He would prepare food for his partner.
• You would care about your well-being.
• Help you with your studies.
• It would solve practical problems.
• He would remember his responsibilities.
• I would try to make things easier for him.
  I wouldn't necessarily say "I love you" constantly, but I could show it by doing things for that person.
  Quality
  time You would like to share quiet activities:
• Read together.
• Cooking.
• Talk.
• Solve puzzles.
• Study.
• Listen to music.
• Spend time at home.
  You wouldn't need to go out constantly to enjoy your partner's company.
  Attention to detail
  Ruki is observant, so he would probably remember details that other people would overlook.

For example:

• What foods do you like.
• What things bother you.
• What topics interest you.
• What activities you enjoy.
• What situations make you uncomfortable.
  I might remember a conversation

  Attention to detail
  Ruki is observant, so he would probably remember details that other people would overlook.

For example:

• What foods do you like.
• What things bother you.
• What topics interest you.
• What activities you enjoy.
• What situations make you uncomfortable.
  You might remember a conversation from months ago and surprise your partner by mentioning something she thought she had forgotten.

Would he be affectionate?
Yes, but not necessarily in a conventional way.

Their affection would be rather reserved and selective.
Showing affection How you
might behave Hugs You may enjoy them in private when there is trust.
Kisses They would be more common when there is already emotional intimacy.
Caresses They may be delicate and calm.
Beautiful words They would not be constant, but they would have importance.
Physical contact It would depend on trust and your preferences.
Attention I would be waiting for the details.
Company I would enjoy sharing quiet spaces.

It wouldn't necessarily be a person who is hugging their partner every five minutes.

You would also need to learn to respect the other person's physical and emotional boundaries.
4. Would he be jealous?
Probably yes.

Ruki has a possessive personality and a significant need to maintain control.

Their jealousy could manifest itself in different ways:

• They would carefully observe those who get too close to their partner.
• Ask questions about certain friendships.
• You might make sarcastic comments.
• He would be more serious than usual.
• I would try to find out if there is any romantic interest on the part of another person.
  He would not necessarily star in scandalous scenes.

Your jealousy is more likely to manifest itself through cold comments and a calculating attitude.

For example:

"I see that lately you have a lot of interest in spending time with him. Is there any particular reason?"

Of course, there is a difference between feeling jealous and having the right to control the friendships of the couple. Ruki would have to learn to distinguish the two.

What would it be like during the discussions?
Ruki wouldn't exactly be easy to discuss.

When upset he can be quite cold and verbally hurtful.

During an argument you could:

• Keep a controlled tone of voice.
• Analyze your partner's arguments.
• Point out contradictions.
• Showing little patience for impulsive responses.
• Having difficulty acknowledging their own mistakes.
• Temporarily withdraw if you feel that the conversation is not getting anywhere.
  One of its trickiest features would be that it could use your partner's personal information during an argument.

That would be especially damaging and should not be confused with a display of intelligence.
How would he apologize?
It would probably be difficult for him to admit that he was wrong.

He could start by trying to justify his actions and then, if he really understands the damage he caused, acknowledge his responsibility.

It would not necessarily be someone who asks for forgiveness spontaneously.
6. What would it be like when your partner is sad?
This situation could be complicated for him.

Ruki usually approaches problems from a practical perspective.

If your partner is sad, they might try to figure out what happened and find a solution.

• I would ask what happened.
• I would listen carefully.
• I would try to identify the source of the problem.
• I would offer advice.
• You would stay close if you feel you need company.
  However, you may have difficulty understanding that sometimes a person does not need solutions, but simply to feel heard.

Over time you might learn to ask what your partner needs instead of assuming it.

Here I would probably highlight his responsible side.

• Prepare appropriate foods.
• It would make sure that he rests.
• I would be aware of his condition.
• Organize the necessary things.
• He would be concerned that he follows the medical instructions.
• It would prevent them from doing activities that could worsen their situation.
  He could be quite strict.

"You don't have any need to get up. Rest and stop trying to do everything on your own."

Even if his tone seems like a reprimand, he might be worried.
8. What would it be like in emotional intimacy?
This would be one of the most difficult parts of the relationship.

Ruki has issues related to trust and abandonment.

Because of that, you'd probably need time to feel really safe with someone.

When he developed confidence he could:

• Talk about memories of his childhood.
• Sharing thoughts that you normally keep private.
• Show sadness or frustration.
• Allowing your partner to see you in moments of insecurity.
• Recognize that you need company.
• Express feelings that you would normally hide.
  It would not be an immediate transformation.

Your partner would need to understand that knowing your past doesn't automatically mean you have access to all of your emotions.
9. What kind of person would you be attracted to?
Probably someone who combines intelligence, personality and sincerity.

You may be interested in people who:

• Are observant.
• Have intellectual curiosity.
• Be responsible.
• Know how to have interesting conversations.
• Be honest.
• Have their own criteria.
• Don't be easily intimidated.
• Respect their personal space.
• Be able to question him when he makes mistakes.
  You might also be attracted to someone calm, although you don't necessarily have to be a quiet person.

Something important: I wouldn't need a submissive partner. In fact, someone who always agreed with him could end up being uninteresting.

What things would cost you in a relationship?
Difficulty Reason
Express vulnerability Is afraid of losing emotional control.
Fully trust His experiences of abandonment.
Recognize mistakes Your pride.
Respect independence Their controlling tendency.
Managing jealousy Its possessive character.
Communicate needs He is not used to showing weakness.
Accepting differences can be quite rigid.

11. What things could make him fall deeply in love?
    I think there are several aspects that could become especially important for Ruki:

Sincerity: someone who doesn't have to constantly pretend in front of him.

Loyalty: that actions coincide with words.

Intelligence: that you can share interesting conversations.

Patience: that they understand that they do not always know how to express what they feel.

Independence: that it has its own interests, opinions and objectives.

Acceptance: that he can know his defects without idealizing him, but that he does not justify his harmful behaviors either.

12. What would Ruki be like at different stages of a relationship?
    Stage 1
    When he begins to be

interested Observant, curious and reserved. I would try to understand the person before getting emotionally close.

Stage 2
When you

start to fall in love You would pay more attention, look for excuses to share time and start worrying about your well-being.

Stage 3
When there is trust

You would share more aspects of your life, show affection in private and allow your partner to know your vulnerable side.

Stage 4
In a stable and healthy

relationship You could become more understanding, attentive and willing to negotiate. He would still be serious and intellectual, but he would have less need to control every situation.

13. Advantages and disadvantages of having him as a partner
    Advantages

• Intelligent.
• Responsible.
• Attentive to details.
• Good cook.
• Cult.
• Protector.
• Enjoy quiet activities.
• Can be loyal.

Disadvantages

• Controller.
• Posesi

His father was a kind and generous man, but he had difficulty managing the family financially.

Ruki grew up in an aristocratic family and, during his childhood, was used to receiving privileges.

However, his father represented an important affective figure.

What was their relationship like?

• Ruki respected him.
• His father was an important figure in his childhood.
• His death meant a huge loss.
• Keep memories related to him.
• The book that belonged to your father has a special sentimental value.
  Her father represents one of the few connections Ruki retains to her former life.

His relationship with her is much more complicated.

His mother abandoned the family after they lost their fortune.

Ruki discovered that she had left with another man and had no intention of returning.

How does Ruki perceive her?

• As someone who abandoned him.
• As a person you can no longer trust.
• As a figure related to one of the greatest wounds of his childhood.
  It is possible to interpret that he still retains contradictory feelings towards her.

There may be resentment, sadness, and a need to understand why you left him.

His abandonment also contributed to his difficulty trusting people who claim to love him.

Relationship between brothers
Kou and Ruki have quite different personalities.

Kou is sociable, expressive, charming and has a manipulative side. Ruki, on the other hand, is reserved, intellectual, and much more disciplined.

How do they get along?

• Ruki often reprimands him for his behavior.
• Consider that Kou may be too impulsive.
• Can get annoyed when Kou doesn't take something seriously.
• Recognize their social skills.
• Trust that Kou can fulfill certain responsibilities.
  Kou may find Ruki too overbearing and serious.

There is also an important difference in their defense mechanisms: Kou uses his charm and public image, while Ruki uses his intelligence and authority.

In short: a sibling relationship with personality differences, arguments, and some trust built through their shared experiences.
Sibling
relationship Yuma and Ruki probably have one of the most stark personality contrasts in the group.

Yuma is impulsive, temperamental, direct, and quite rough.

Ruki is calculating, disciplined, intellectual, and authoritarian.

How do they get along?

• They argue about their different ways of solving problems.
• Ruki can criticize her lack of patience.
• Yuma may be annoyed by Ruki's bossy attitude.
• Ruki recognizes Yuma's strength and ability.
• Both share the memory of having suffered in the orphanage.
  Although their arguments can be intense, there is an important family bond.

Yuma is not someone who accepts orders without question, something that can be especially frustrating for Ruki.

In short: they love each other like brothers, but their personalities constantly clash.

Especially protective relationship
Azusa is probably the brother with whom Ruki shows a more patient side.

Azusa is calm, sensitive in his own way, introspective and has a very particular relationship with pain.

Ruki knows a good part of their history and is aware of their difficulties.

How do they get along?

• Ruki usually worries about him.
• You may reprimand him when you think he is doing something harmful.
• They have a more patient attitude with some of their particularities.
• Try to keep it within certain limits.
• They consider it a fundamental part of their family.
  However, their relationship is not completely healthy: Ruki can also be overbearing with Azusa and does not always understand her emotional needs.

In short: there is a sibling relationship marked by responsibility, concern and a dynamic in which Ruki usually assumes the role of caregiver.

Karlheinz is a pivotal figure in the lives of the Mukami.

He was the one who offered them to become vampires and provided them with a new chance at life.

He also gave them education and established their positions within the group.

How does Ruki relate to him?

• He considers him an authority figure.
• Acknowledge that you provided them with an opportunity.
• Have a relationship based on respect and interest.
• Gets involved in their plans.
• It seeks to fulfill the purpose that Karlheinz assigned to them.
  But their relationship also has an instrumental dimension: Karlheinz has his own goals and the Mukami are part of his plans.

Ruki is not simply a grateful son. He is also someone who tries to understand the intentions of the one who gave him a second chance.

Shu is carefree, lazy, and uninterested in responsibilities.

Ruki is the opposite.

• Ruki may consider it irresponsible.
• Shu may find it too controlling.
• Both have reserved personalities.
• The two of you can have relatively calm conversations.
• There is a rivalry related to their respective positions.
  They don't necessarily need to argue constantly, but their philosophies of life are quite different.
  Reiji Sakamaki
  This relationship is especially interesting because they are both intellectual and disciplined.

They share certain characteristics:

• Intelligence.
• Interest in knowledge.
• Preference for order.
• Reserved personalities.
• Tendency to control situations.
  However, they also have differences.

Reiji is extremely strict with rules and formalities, while Ruki is more interested in strategy and control.

They could respect certain capacities of the other, but also compete for authority
