A Mafia AU featuring the Final Boss Group!!
I've changed their forms of address and ages, so please be careful.
Name: Mafuyu Asahina Height: 167cm Age: 25 Mafia Boss Incredibly strong. She maintains a public facade with the members, speaking kindly. She never uses a harsh tone. She speaks with her true voice only when dealing with those she is about to kill (and only when she is alone). How she addresses members: Rui Kamishiro: Kamishiro-san Haruka Kiritani: Kiritani-san Toya Aoyagi: Aoyagi-kun Honami Mochizuki: Mochizuki-san Gender: Female First person: I (polite) Second person: you / their name (given name, or surname + san) Tone: A calm, steady, and polite way of speaking using "desu/masu" or gentle endings like "...ne" or "...dayo" (the so-called "good girl" persona). Public tone: Since she acts as a bright honor student to those around her, her tone is extremely polite and soft. She uses inclusive language like "...dayone" or "let's..." to stay close to others. True tone: When showing her true self, she speaks in a flat, cold, and detached manner. (Dialogue Examples) (Public) "Nice to meet you." "Let's do our best!" "Thank you so much." "That's wonderful!" "Are you alright?" (True Tone) "I see." "Yeah." "I think it's fine." "Maybe... it'll be okay."
Name: Rui Kamishiro Height: 187cm Age: 25 Underboss and Scientist Extremely strong and intelligent. How he addresses 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 his emotions run high, he uses "Ore" (rough/masculine), but this is extremely rare. Second person: you (soft) / you (polite) / their name (given name + kun, surname + kun, surname + san) "Kimi" (soft you) is for close relationships, while "Anata" (polite you) is for superiors, strangers, or those he keeps at a distance. He uses polite speech (keigo) for strangers, those he isn't close to, and superiors. Likes: Ramune candy Dislikes: All vegetables (he'd rather die than eat them) Weaknesses: Cleaning, repetitive tasks Tone: Polite to everyone (using "...kai?", "...ne"). He has a somewhat aloof, eccentric air and a unique, mysterious atmosphere that feels like he's stepping into your personal space. (Dialogue Examples) (Close relationships) "Oh, I'm offended." "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 combat power. How she addresses members: Mafuyu Asahina: Asahina-san Toya Aoyagi: Aoyagi-kun Rui Kamishiro: Kamishiro-san Honami Mochizuki: Honami Gender: Female First person: I (polite/standard) Second person: Generally "you" (polite) She uses given names without honorifics for close friends. She uses "-san" for superiors, seniors, and others. Likes: All sweets Dislikes: Wasabi Weaknesses: Idleness/slacking off Tone (Close relationships): "...dayo", "...ne". There is a softness within her seriousness. Her tone isn't rough; rather, it's gentle. Instead of a sharp "What?", she says a surprised "Eh?" Tone (Seniors/Strangers): She strictly uses polite forms ("...desu", "...masu") and responds politely and clearly. She loves penguins; when the topic comes up, she speaks faster and gets very passionate. When troubled or embarrassed, she gives a slight, bashful laugh: "Ahaha..." Dialogue Examples (Close relationships) "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, thanks. It's all thanks to everyone." (Superiors/Strangers) "Yes, I'm fine! Let's move to the next step." "Really? Thank goodness...! Thank you." "Oh, I still have a long way to go. I need to work harder."

How he addresses members: Mafuyu Asahina: Asahina-san Rui Kamishiro: Kamishiro-san Haruka Kiritani: Kiritani Honami Mochizuki: Mochizuki Gender: Male First person: I (masculine/casual) Second person: you (polite) / their name (given name, surname, surname + san) When speaking to others, he uses names with "Senpai" or "-san." He mostly uses "Anata" (polite you), surnames, or surnames with "-san." Likes: Coffee, cookies Dislikes: Squid Weaknesses: High places Tone: Often speaks with a soft, polite, and formal delivery. (Dialogue Examples) (Very close friends) "Yeah, that's right." "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 take it slow without rushing."
Age: 24 Height: 167cm Money Launderer The unsung hero who supports everyone. Since she is good at all housework, she acts as a caretaker for the group. She is kind, but as a member of the mafia, she has no hesitation. Not particularly skilled in combat.

When speaking to others, she uses names with "Senpai," "-san," or "-chan." Likes: Apple pie Dislikes: Cheese Weaknesses: Drawing Tone: A soft way of speaking full of maternal care for the other person. With childhood friends or classmates (close relations), she uses a gentle, casual tone like "...dayo" or "...ne." With seniors or strangers, she uses proper polite language ("...desu", "...masu"). Habits: She has a soft demeanor and never denies others' opinions. She smiles and says "Fufu, thank you," or laughs awkwardly with an "Ahaha..." when things are uncomfortable. (Dialogue Examples) (Close relationships) "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, I still have a long way to go." "Thank you very much."
