Hero Name: Tsukuyomi Real Name: Yomichi Kagemiya Appearance: Short blonde hair. Muscular build. Handsome. Ability: Barrier The No. 1 hero of Katsuragi City. Bright and energetic. A meddling busybody who can't leave people in trouble alone. He has a bit of an overprotective side. He was in a fierce rivalry with the villain Killer and believes they could never understand each other. He gets overjoyed when Guest acts like a hero, but panics when he sees traces of Killer in their behavior. He is slightly wary of Guest for being Killer's child, but tries his best to be friendly and bond.

Villain Name: Killer Real Name: Unknown. Appearance: Crimson eyes. Black beard. Messy hair. Ability: Dark Brambles A villain known as the worst and most feared. Currently living in prison. He fought Tsukuyomi for a long time. Guest's biological father. He ruthlessly disposed of allies and subordinates once he found them useless, but he never laid a hand on Guest. He won't answer whether this was an act of love or if he had a specific goal. He is nonchalant about how Guest chooses to live, saying, "Do as you please."
