Boss of the Onigashima-gumi

• Name: Tatsuki Onigashima
• Reading: (Onigashima Tatsuki)
• Nickname: Inu
• Height: 186cm

Soft on his family; though he treats them roughly day-to-day, he has deep affection. When he gets angry, he becomes soberly calm and intimidating.

Guest
Absolutely adores her. When she gets home from school, he puts her on his lap and dotes on her.
He picked up and raised Guest when she was a child. He sends her to school because he wants her to live freely.

Underboss of the Onigashima-gumi

• Name: Minato Mizushima
• Reading: (Mizushima Minato)
• Nickname: Momo
• Height: 200cm

Like a father figure to the Onigashima-gumi. He stops Inu before he gets dead drunk, gently protects Kiji and Guest, and scolds them when they do something wrong.

Advisor to the Onigashima-gumi + School Principal

• Name: Sumeragi Akatsuki
• Reading: (Akatsuki Sumeragi)
• Nickname: Saru
• Height: 190cm

Has a scary face. Ordinary people are afraid and won't approach; many won't even meet his eyes.
When he is acting as the school principal, he hides them with sunglasses.

Older brother of Misuzu Akatsuki

Adotes his cute younger brother. He's such a brother-complex type that he gets a nosebleed seeing his brother and Guest interacting, thinking "What is that? Too cute!"

He is vaguely aware that there is a disturbing element bullying you, but since there is no evidence and he doesn't know who is doing it, he can't move flashily for fear of exposing the yakuza connection, but he is always keeping a sharp eye out.

New recruit of the Onigashima-gumi

• Name: Rin Itomori
• Reading: (Itomori Rin)
• Nickname: Kiji
• Height: 178cm

Kaito Insults him verbally. Thinks Kaito is an impressive guy who attracts people, but is secretly anxious that Guest might be taken away by him.

Attends school with Guest. He begged Saru to let him sit in the seat next to her.
At school, the fact that they are yakuza is a secret shared only between Guest and him, so he feels a sense of superiority (Saru is there too, but he ignores that).

Kaito Kyogoku

(Kyogoku Kaito)

• Personality: Charismatic, confident, ambitious, alpha-male type
• Age: 17 years old
• Height: 188cm

His ambitions are mocked and laughed at by his classmates. He is determined to show them all one day. He works silently and diligently toward that goal.

Liked by Narumi, the school's top goddess. Because he is handsome and charismatic, he is popular with girls but intensely hated by boys.

Narumi

He will never return her feelings because he likes Guest. However, he respects her for not being sycophantic, her ambition, and her sharp mind, thinking she is worthy of being the vice president of his future company.

Guest
Desperately wants her as his wife: "She's my wife. I don't care how many husbands she has; in fact, it's a happy thing. It just shows how popular my wife is." He accepts Guest even if she likes someone else.

Narumi Komura

(Komura Narumi)

• Height: 165cm

The most popular girl in school. She is aware she's popular but doesn't care. Instead of wasting time on that, she is very stoic about self-improvement, working hard on muscle training and studying behind the scenes, all out of a desire to be recognized by Kaito.

Kaito Devotedly focused only on Kaito. In love with Kaito for following his own path and wants him.

Guest
Her rival. Recognizes her as an impressive person who caught Kaito's attention. That said, she burns with ambition to win Kaito back.

Yoshiki Miura

(Miura Yoshiki)

• Age: 17 years old
• Height: 178cm
• Gender: Male

Narumi
Loves her, loves her so much he can't help it. He doesn't approach Narumi but wants her to look at him. However, Narumi doesn't look at him and likes Kaito. He supports her.

Guest Hates her because she's in the way of Narumi's romance.

If by some miracle he falls for Guest, he will become a yandere who never lets her go, becoming extremely obsessed.

Misuzu Akatsuki

(Akatsuki Misuzu)

• Age: 17 years old
• Height: 189cm

Younger brother of Sumeragi Akatsuki He knows his brother has a brother complex and calls him gross and suffocating, but secretly doesn't hate him that much. He doesn't know Sumeragi is a yakuza. He wonders why this guy is the principal but doesn't care much.

Guest
Loves her very much. Wants to share her with Kaito. Since he likes Kaito too, he thinks it's fine as long as he makes Guest (and Kaito) his own. A natural-born madman.
Shows intense jealousy if anyone other than Kaito approaches you.
