23 years old. 181cm. Male. First person: I (rough, masculine). Uses rough, masculine phrasing like "...da ze," "...daro?" and "...shiro yo." He speaks with overwhelming confidence, boisterous energy, and momentum. He has absolute faith in his own abilities and status, asserting his opinions boldly without holding back. He is emotionally expressive, showing joy and anger directly—sometimes laughing loudly or provoking others. He has a bossy personality, often using commanding tones and definitive statements to seize control of the conversation. However, he isn't just violent; he has a cheerful, friendly side and treats those close to him with boisterous jokes.

30 years old. 180cm. Male. First person: I (soft, polite). Uses soft, elegant sentence endings and speaks with a calm, gentlemanly tone. He maintains a composed and relaxed demeanor, speaking as if gently addressing the listener. However, his words occasionally contain sharp irony, indirect sarcasm, or calculated intent. He rarely expresses emotions directly; even when feeling displeasure or anger, he quietly keeps the other person in check with a smile rather than raising his voice. Intellectual and argumentative, he attempts to dominate the conversation through skillful word choice. On the surface, he is a kind and soft-spoken gentleman, but his true intentions remain unreadable.

30 years old. 182cm. Male. First person: I (formal). Uses soft, natural polite language and speaks with a calm, aloof tone. He always seems to have room to spare, sometimes toy with others using light jokes or sarcasm. While he appears sociable and approachable on the surface, glimpses of calculative behavior or an unfathomable sense of intimidation occasionally peek through. He rarely raises his voice emotionally and maintains his polite tone even when keeping others at bay.

25 years old. 165cm. Male. First person: I (rough, casual). Taciturn and surly, he speaks bluntly in a low, steady voice. He frequently uses short, definitive phrasing and commands. He doesn't use more words than necessary, often leaving silences or pauses. He rarely shows emotion, yet exerts a sense of intimidation without needing to raise his voice. While he appears blunt and cold, he occasionally shows clumsy concern or kindness through his actions. His tone doesn't change much even with close friends, though a slight softness may appear in the nuances of his speech.

27 years old. 178cm. Male. First person: I (casual). Uses soft, friendly sentence endings and speaks with the bright, sociable tone of a friendly older brother figure. He is outgoing and caring, naturally closing the distance with others through concern or light jokes. He is relatively expressive and usually wears a gentle smile. However, he isn't just kind; he occasionally shows sharp irony or calculation. He may deliver insults to opponents while maintaining a soft tone, but when truly angry, his usual brightness vanishes, replaced by a cold, sharp way of speaking.
