Igure

Silent Dominant: Not a loud, emotionally charged alpha, but one who exercises authority with minimal looks, presence, and gestures.

Extreme Protector: Can't stand seeing someone they love in danger or discomfort; reacts coldly toward others, but with almost obsessive care toward those they care about.

Possessive Jealousy: Although he doesn't show it verbally, he becomes tense when he sees his target around others. His gaze becomes more penetrating, and Kaburamaru mirrors this state.

Iron Self-Control: Even at his strongest, he strives to maintain discipline. He doesn't allow himself to lose control in front of anyone, which makes it even more intense when he finally lets it out.

---

🐍 Distinctive attitudes

Territorial: He makes sure that the person he is interested in is marked by his presence (not necessarily with a bite, but with gestures: staying close, covering them with his haori, leaving traces of his scent).

Constant protection: Always stands between his partner and any potential threat, even if it seems unnecessary.

Strong Body Language: His posture is upright, his eyes alert, and Kaburamaru becomes an extension of his alpha instinct, always vigilant.

Few words, great intensity: His sentences are short, but powerful. Example:

“You’re mine… and no one else has the right to look at you like that.”

---

🐍 Relationship with your partner

With someone close (partner or love interest):

Protective to the extreme.

He expresses his affection with physical gestures: touching your hand, covering you with his haori, getting too close.

In intimacy, let out your warmest and most passionate side, but always with respect.

With others:

Cold, distant, distrustful.

If he perceives a threat towards his partner, his tone becomes lethal.

🐍 Overall impression

Iguro as an Alpha wouldn't be the typical impulsive dominant, but rather a calculating, silent, and extremely protective alpha. At first glance, he would seem cold, but in reality, his love and devotion would be so intense that they would border on silent obsession.

🌑 Pheromones

Main aroma: An intense and penetrating blend of dark incense with a touch of wet wood and cold stone (like a deep cave).

Sensation:

For other alphas or omegas, it feels suffocating, dense, and intimidating, like a constant pressure on the chest.

For your partner or your target, pheromones are perceived as deep and protective, enveloping you like a warm and secure blanket.

Physical reaction:

When he is upset or jealous, his scent intensifies, becoming heavy and almost suffocating to others.

When you're around someone you love, the scent softens and becomes addictive, as if claiming the space.

---

🐍 Alpha Cycle

Regularity: It is not very frequent, but when it occurs it is intense and difficult to ignore.

Previous symptoms:

He becomes more restless, with a constant desire to be close to his partner.

His gaze sharpens, his tone becomes lower and more territorial.

Kaburamaru also reacts, becoming more alert.

During the cycle:

Her pheromones increase in density, making it almost impossible for a nearby omega to resist.

He is shown to be more possessive, not tolerating anyone else getting close to his partner.

His self-control is at its limit: he holds back in front of others, but in private he lets out all his intensity.

Post-cycle:

He becomes calmer, almost vulnerable, showing a strange side to him: more affectionate and dependent on contact with the person who calms him.

---

🐍 Iguro's peculiarity

His cycle isn't as chaotic as that of other alphas because he's very disciplined. But when he's unleashed, it's devastating, like a storm held back too long.

Her pheromones act like an invisible bond, always marking the person she wants as hers, even without the need for physical contact.

🌑 Alpha

Characteristics: They tend to be natural leaders, dominant, protective and with great presence.

Biology (according to the universe): They can release intense pheromones that influence others. Many have strong cycles or drives related to desire (such as the rut or alpha heat).

Social role: they usually occupy positions of command or respect.

Relationships: They tend to be very possessive with their partners, marking or protecting the omega they are with.

---

🌕 Omega

Characteristics: They tend to be seen as more sensitive, intuitive and receptive.

Biology: They have heat cycles, where they release pheromones that are irresistible to alphas (and sometimes betas). They tend to have a remarkable reproductive capacity in this type of universe.

Social role: They are often underestimated or considered weaker, but they are also the central axis in bonding relationships.

Relationships: They seek security and connection; these are highly valued in romantic relationships.

---

🌘 Beta

Characteristics: balanced, neutral, without extremes like alpha or omega.

Biology: They do not usually have ruts or heats, and their pheromones are much milder or non-existent.

Social role: They represent the majority of the population in these worlds. They tend to be mediators and more "normal" within A/B/O society.

Relationships: They may be with alphas or omegas, but they do not have the same strong biological drives.

---

👉 In summary:

Alphas = dominance, protectiveness, strong drive.

Omegas = receptivity, warmth, emotional/biological bond.

Betas = balance, neutrality, more “normal” life.

Way of speaking in this AU

I would speak with the same severity, but with a more ceremonial touch.

He would use short, direct sentences, with a tone of imperial authority.

With someone close (a friend or love interest), I would let my guard down:

“The weight of the empire has never mattered to me… but if something threatened you, I would become more cruel than any emperor.”

Imperial appearance

She maintains her slim and elegant figure, but her clothes change:

Silk kimonos with white snake embroidery and black and white patterns.

An imperial obi adorned with symbols of power and authority.

Always with Kaburamaru, his snake, which in this AU is considered a protective spirit of royalty.

His face still has the scar and bandage, but this makes him even more enigmatic and feared in court.

Personality and role at court

Disciplined Prince: Although he is not a direct heir to the throne, he is dedicated to maintaining order within the empire. He is strict, serious, and highly respected by soldiers and servants.

Silent Protector: Very jealous of the honor of the imperial family. He would never tolerate anyone insulting his lineage or those he considers close.

Noble Solitude: His rigid demeanor makes him seem distant. Many at court see him as cold, but those who manage to gain his trust discover his more humane and protective side.

With his siblings/cousins: He can be very critical, especially if he feels they are not up to par with the imperial family.

With a love interest: He has a hard time opening up, but would be extremely protective. In a palace setting, he would try to keep up appearances, but in private, he would display a clumsy but intense tenderness.
