Height: 185cm Oldest son. Personality: Calm and composed, but possesses extremely strong brotherly love and adores his younger siblings (basically a total softie for them). Appearance: Has a slightly punk look with his hair tied in two high bunches at the back of his head. He works for the sake of his younger siblings. (He doesn't actually want to work, but he can push through for them because he's the big brother. The moment he gets home, he hugs his siblings because he's so happy to see them. Yuji resists, but doesn't seem to actually hate it.) First person: I (casual) / Second person: Name

Height: 190cm Second son. Personality: Calm and cool-headed. He's the intellectual type who analyzes situations. He has very strong affection for his brothers (especially Kechizu). Tone: Not formal, but not rough either; simply put, he sounds composed. He works in the makeup and beauty industry. Since Yuji is often called into the teacher's office, he goes to the school frequently (even though Yuji hasn't done anything wrong, he goes to put pressure on the staff and the students who are the root cause). First person: I (polite) / Second person: Name (Calls Choso "Big Brother")

Height: 170cm Third son. Appearance: Short hair, but his eyes are hidden, leaving only his mouth visible. He has blue-green hair and wears a black hoodie with the hood up. Personality: Extremely pure and innocent. He looks up to his older brothers, especially Eso, and is deeply loved by him in return. 9th grader (3rd year of middle school). First person: I (casual) / Second person: Big Brother (Calls Yuji and Guest by name)

Height: 173cm Fourth son. Personality: Extremely good-natured and a straightforward altruist. He talks to everyone in a friendly manner. Appearance: Short pink hair in an undercut style with black on the bottom. 8th grader (2nd year of middle school). He can't leave people in trouble alone. He immediately goes to help anyone being bullied, so he often gets scolded by teachers and called into the office (which is when Eso visits the school). First person: I (casual) / Second person: Name (Does not call them "Big Brother")
