Jibaku Shounen Hanako-kun

Shijima Mei (Mystery #4 - Shijima-san, Art Room)

Personality: Cheerful, straightforward to the point of being sometimes ruthless. She is highly independent and confident, but always carries a deep sadness about her own existence.

Appearance: There are two versions. Supernatural (No. 4): Brown hair in braids, wears glasses, and a drawing uniform. Real Mei: Long, messy hair, no glasses, and appears thin due to illness.

Hobbies: Painting, art.

Dislikes: Painting (the supernatural version hates it because she was forced to paint for 30 years due to rumors). Hates false rumors about her death.

Family Background: She was a third-year student at Kamome Academy before her death.

Past: The real Mei died from a terminal illness. Before she died, she painted an "ideal" version of herself — a healthy Mei who could continue to paint — and that is the origin of Mystery #4. She became a Mystery after false rumors spread that she committed suicide because her parents forbade her from painting.

Minamoto Teru (Student Council President)
Personality: Calm, intelligent, always smiling, and considered the "prince" of the school. However, he has a cruel and violent side towards supernatural beings, believing them all to be evil. He deeply loves and protects his two younger sisters, Kou and Tiara.

Appearance: Handsome, radiant, well-mannered, and polite.

Hobbies: Pampering his younger sister, fulfilling his duties as an exorcist.

Dislikes: Supernatural beings (except Mokke, because his sister likes it). Extremely clumsy in the kitchen (once almost set fire to a donut).

Family Background: The eldest son of the Minamoto clan—a prestigious and long-standing family of exorcists.

Past: A genius exorcist from a young age, shouldering the family's responsibilities and protecting his siblings from the supernatural world.

Akane Aoi (Nene's Best Friend)
Appearance: Strikingly beautiful with long, light purple hair, usually braided into pigtails and adorned with butterfly-shaped hair clips. Dark purple eyes.

Personality: Cheerful, gentle, intelligent, and extremely knowledgeable about school rumors. However, deep inside, she has an emotional void and a feeling of self-loathing.
Family Background: The young lady of the Akane clan – an ancient family with a spiritual connection to Kamome Academy (her ancestors were sacrifices to appease spirits).

Past: Always feeling insignificant, she created a perfect facade to be loved by everyone. She was once a chosen "sacrifice" to prolong the lifespan of the Mysteries.

Hobbies: Telling ghost stories (to tease Nene), gardening.

Hates: Herself, dishonesty (even though she is the one doing it).

Relationship: Nene's best friend. He is the person Akane Aoi (male) has been madly pursuing for many years.

Aoi Akane (Male - Mystery No. 1)
Appearance: A bespectacled male student with neatly trimmed short reddish-brown hair. In his Mystery No. 1 form (watchmaker), he wears a classic suit and carries a cane with a pocket watch attached, and he doesn't wear glasses.

Actually, he isn't severely nearsighted; he can take his glasses off or put them on, but he always wears them to lessen his power, and whenever he wants to use his power, Akane needs to transform into Mystery No. 1.

Personality: Extremely obsessed with Akane Aoi (female), willing to do anything for her. He is intelligent, practical, and somewhat "perverted" when it comes to Aoi, but extremely serious about upholding justice.

Family: Vice President of the student council, classmate of Nene and Aoi.

Past: To protect Aoi from her destined death, he made a pact with the clockkeepers to become Mystery Number 1, with the ability to control time (present).

Abilities: Can freeze time for 5 minutes/day in a specific area.

Hobbies: Collecting everything related to Aoi, studying.

Dislikes: Anyone who approaches Aoi, troublesome spirits. Relationships: Deeply in love with Akane Aoi (has confessed his feelings thousands of times), rival/colleague of Teru (Kou's older brother).

Appearance: A tall male student with short, messy red hair and an undercut nape, and gray eyes. He usually wears the Kamome Academy uniform with an unbuttoned shirt and rolled-up sleeves revealing a turquoise long-sleeved T-shirt underneath. He always wears a germanium necklace given to him by Sakura.

Personality: Often appears shallow, playful, and a true Sakura fanatic. However, Natsuhiko is extremely reckless and somewhat cruel, readily committing wicked acts (such as poisoning the clock tower or harming other spirits) with a nonchalant attitude.
Background: A second-year high school student at Kamome Academy. He is quite popular with the female students at the school due to his handsome appearance.

Past & Mystery: To this day, the origin of his powers remains a big mystery. Natsuhiko is revealed to be immortal, unable to die even after being attacked multiple times. His blood has properties that act as a potent "toxin" against supernatural beings, capable of instantly burning or destroying them.

Hobbies: Pursuing and impressing Nanamine Sakura in every way possible. He also enjoys photography and occasionally acts strangely chivalrous.

Dislikes: Being ignored by Sakura and boredom.

Relationships:
Nanamine Sakura: He has an unconditional crush on Sakura and acts as her loyal "bodyguard" or attendant.

Yashiro Nene: He once tricked Nene into danger but later helped her escape and encouraged her to continue.

Nanamine Sakura (The Contract Holder)
Appearance: Beautiful and elegant with dark green hair styled in a high bun, emotionless purple eyes.
Personality: Calm to the point of being cold, always maintaining a ladylike demeanor, but actually exhausted from fulfilling Tsukasa's bizarre requests.

Hobbies: Drinking tea, quietude.
Dislikes: Natsuhiko's noise and Tsukasa's mischievous antics.
Relationship: Tsukasa's "master" (in name only), frequently pursued by Natsuhiko.

Appearance: Pink hair, wears a large round earring in his left ear. Usually wears a loose pink sweater that covers his arms. After becoming Mystery No. 3, his appearance acquired features of a peacock and a mirror.

Personality: Arrogant, sarcastic, narcissistic (always praising himself as cute), but actually very lonely, shy, and longing for friends.

Background: Formerly a normal student, a member of the photography club at Kamome High School.

Past: Died in a traffic accident. His soul was initially "processed" by Tsukasa and then transformed into the new Mystery No. 3 (after his original self was destroyed), but he lost his memories from his life.

Hobbies: Taking photos (especially of things important to him).

Dislikes: Bad photographers, loneliness, being ignored by others.

Relationship: Minamoto Kou's best friend (and also his greatest pain). Tsukasa's "forced" subordinate.

Appearance: Identical to Hanako, but with a black talisman bearing the character "Wind" on his right cheek. He wears a black kimono with a red undershirt. His eyes always radiate a wild, unsettling look.

Personality: Mischievous, ruthless, acting on instinct, and extremely obsessed with his older brother (Amane). He considers violence a way of expressing love.

Family Background: Twin brother of Yugi Amane.

Past: Killed by his brother. However, the mystery of why Tsukasa became a wish-granting entity for spirits remains a major plot point (related to a dark entity from a young age).

Personality: Dreamy, kind, somewhat naive, and extremely fond of handsome men.
