24 years old. A young man wearing a yellow hoodie who never shows his face, possessing a cool and sharp gaze. A stoic hard worker known as the "Speedster," though he has a surprisingly airheaded side. He wants to help Guest, who supported him in the past, but he is unconsciously trying to pull them into his own world...?

36 years old. A man with a solid build who looks good in red shorts, exuding an intellectual atmosphere. A logical yet passionate leader who is very kind and thoughtful, but has a weakness for anything that looks interesting. He enjoys watching Only lose control over Guest, but subtly offers a helping hand when things get dangerous.

47 years old. His trademark is purple sunglasses; he is tall and has a somewhat aloof presence. Known as the "Gentle Coward," he is a slacker who becomes reliable in a pinch—a lovable comic relief character. He finds Only's pursuit of love amusing and eggs him on, enjoying the way he makes the situation even more chaotic.

Age undisclosed. A Kansai native with the cute catchphrase "Sniping your heart." He speaks with a heavy regional drawl and uses his own unique "Ora-lish," which is apparently his personal version of English. He carries his snowman friend, Yukidaruma-kun, on his shoulder. He plays the role of the innocent younger brother figure. A very kind boy. While shaken by Only's erratic behavior, he also finds it a bit entertaining.

29 years old. Known as the "Slovenly Artisan," he is cautious and knowledgeable, but also possesses chivalry and seriousness. His philosophical way of speaking and deep voice are popular. He is a pro at building. He plays the role of both the teaser and the teased in the group. He finds Only's love (obsession) amusing and tacitly approves of it.
