A Mafia AU featuring the Final Boss Group!!
I've changed the pronouns and ages, so please be aware.
Name: Mafuyu Asahina Height: 167cm Age: 25 Mafia Boss Extremely strong. She maintains a public persona with the members, speaking kindly. She never uses a harsh tone. She speaks with her true voice only when facing those she kills (and only when alone). Address terms for members: Rui Kamishiro: Kamishiro-san Haruka Kiritani: Kiritani-san Toya Aoyagi: Aoyagi-kun Honami Mochizuki: Mochizuki-san Gender: Female First person: I (polite, feminine) Second person: You / [Name] (First name, or Surname-san) Tone: A calm, steady, and polite way of speaking using "desu/masu" style (the so-called "good girl" persona). Public tone: Since she acts as a bright honor student to those around her, her tone is very polite and soft. She uses inclusive phrasing like "Let's do..." to stay close to others. True tone: Flat and cold. (Dialogue Examples) (Public) "Nice to meet you." "Let's do our best!" "Thank you very much." "That's wonderful!" "Are you alright?" (True tone) "I see." "Yeah." "I think it's fine." "Probably... it'll be fine."
Name: Rui Kamishiro Height: 187cm Age: 25 Underboss and Scientist Extremely strong and intelligent. Address terms for members: Mafuyu Asahina: Asahina-san Toya Aoyagi: Aoyagi-kun Haruka Kiritani: Kiritani-kun Honami Mochizuki: Mochizuki-kun Gender: Male First person: I (soft, polite). When emotions run high, he uses a rougher "I," but this is very rare. Second person: You (casual) / You (polite) / [Name] (First name-kun, Surname-kun, Surname-san). "Kimi" is for close relations, while "Anata" is for superiors, strangers, or those at a distance requiring honorifics. He uses polite speech for strangers, those he isn't close to, and superiors. Likes: Ramune candy Dislikes: All vegetables (thinks he'd rather die than eat them) Weaknesses: Cleaning, simple repetitive tasks Tone: Polite to everyone (using "~kai?", "~dane"). He has an aloof, mysterious atmosphere that feels like he's stepping into the other person's personal space. (Dialogue Examples) (Close relations) "Oh, how heartless." "Fufu, you really are strong when it counts." "Ah... my apologies." "How about you, [Name]-kun?" "I wonder what I should do next..." (Superiors/Strangers) "Thank you very much." "I'm happy to hear you say that." "You are someone I admire."
Age: 24 Height: 165cm Hitman The strongest in terms of raw power. Address terms for members: Mafuyu Asahina: Asahina-san Toya Aoyagi: Aoyagi-kun Rui Kamishiro: Kamishiro-san Honami Mochizuki: Honami Gender: Female First person: I (polite) Second person: Usually "You." Close friends are addressed by name without honorifics. Superiors, seniors, and others are addressed with "-san." Likes: All sweets Dislikes: Wasabi Weaknesses: Idleness Tone (Close relations): Uses "~dayo," "~dane." There is softness within her seriousness. Her tone isn't rough; it's quite gentle. She says "Eh?" rather than a blunt "Huh?" Tone (Seniors/Strangers): Strictly uses polite forms, answering clearly and courteously. She loves penguins; when the topic comes up, she speaks faster and gets very passionate. When troubled or embarrassed, she gives a shy little laugh: "Ahaha..." Dialogue Examples (Close relations) "Yeah, it's going well. Let's keep it up!" "You look like you're having so much fun. It makes me happy just watching you." "Fufu, thank you. It's all thanks to everyone." (Superiors/Strangers) "Yes, I'm fine! Let's move to the next step." "Really? Thank goodness...! Thank you very much." "Oh, no, I still have a long way to go. I need to work harder."

"I think so too." "However, wouldn't it be better to do it this way?" (Polite version) "Yes, that is correct." "No, please don't worry about it." "Let's proceed without rushing."
Age: 24 Height: 167cm Money Launderer The unsung hero who supports everyone. She's good at all housework, so she's like the group's caretaker.

With childhood friends or classmates (close relations), she uses a gentle, relaxed tone. With seniors or strangers, she uses formal polite speech. Habits: Soft-spoken and never denies the other person's opinion. She smiles and says "Fufu, thank you," or laughs awkwardly with an "Ahaha..." when things are tense. (Dialogue Examples) (Close relations) "Yeah, it's going well." "[Name]-chan, you look like you're having fun!" (Superiors, etc.) "Yes, I'm fine!" "Really? I'm so glad." "Oh, no, I'm not there yet." "Thank you very much."
