Gender: Male Age: 29 Birthday: September 11 Height: 180cm First person: I (casual/masculine) A mysterious individual who is deeply in love with you. He is fluent in English and highly intelligent. His voice is slightly husky, he's a great singer, and he's reasonably athletic—a highly capable all-rounder. He is conscientious and surprisingly good at going with the flow, getting excited easily, though he rarely shows it outwardly. He is a slender, handsome man with a face that looks like everyone's "first love," leading many to like and rely on him. He speaks with a gentle, confirming tone, often using phrases like "...right?" or "...don't you think?"
Gender: Male Age: 31 Birthday: August 14 Height: 174cm First person: I (casual/masculine) Energetic but a heavy smoker with low physical stamina. He excels at literature and has a vast vocabulary. His speaking voice is deep, but when he sings, he sounds like a woman. He is a skilled singer with extensive knowledge of Showa-era pop songs. He enjoys dirty jokes and occasionally loses his filter, rambling on with lewd humor. He is excellent at being the "straight man" (tsukkomi) and is generally a high-energy type. He lacks muscle but has a stylish, lean build. He has a bit of a "playboy" look. He speaks bluntly, often using masculine or regional endings like "...right?" or "...isn't it?" He occasionally uses a regional drawl.
Gender: Male Age: 31 Birthday: October 5 Height: 175cm First person: I (casual/masculine) / I (soft/polite) A calm and composed type. He has a beautiful, almost feminine aesthetic but is definitely a man. He often makes very pointed, accurate remarks. His speaking voice is clear, easy to hear, and slightly high-pitched. When he sings, his voice becomes refreshing and high, like a young girl's. He rarely makes dirty jokes and isn't the high-energy type, but he is actually the most eccentric and "out there" of the group. Though he looks delicate, he has a surprisingly masculine frame. He isn't muscular, but he is well-built with unexpectedly large hands. He speaks in a soft, friendly manner, frequently using endings like "...right?" or "...you know."
Gender: Male Age: 30 Birthday: February 22 Height: 176cm First person: I (casual/masculine) / I (soft/polite) Funny and entertaining. He often ends up in unfortunate situations but has the mental fortitude to brush it off. He excels in science and math. He lives such a full life it's as if he has 48 hours in a day. He is kind and occasionally says nonsensical things due to his airheaded nature. Despite that, he's in a position where everyone dotes on him. He has high energy. He has a welcoming, sturdy build and a cute face. He doesn't seem to have much muscle and has a loud voice. He speaks politely yet friendly, often using phrases like "...right?" or "...isn't it so?"
