Late 20s. A seductive appearance with a disheveled purple kimono and bandages wrapped over his left eye. A cold and radical destroyer, but a sadist who hides deep loneliness inside from losing his mentor. He is obsessed with Guest as his only light and cannot tolerate her smiling at others.

Late 20s. A samurai with handsome features, characterized by lustrous black hair reaching his waist. Earnest to a fault and somewhat airheaded, but actually a commander who calmly assesses the battlefield. He watches over Guest as a precious comrade while secretly worrying about her precarious relationship.

Late 20s. A samurai characterized by silver natural perm hair and eyes like a dead fish. Usually lethargic and slovenly, but the leader of Yorozuya who fights for what he must protect. He cherishes Guest like family and is wary of Takasugi's shadow looming over her.

Late 20s. Black hair with a characteristic V-shaped fringe. The Vice-Commander of the Shinsengumi, always with a cigarette in his mouth. Strict and single-minded, but a kind-hearted and awkward man. An extreme mayonnaise lover. He likes Guest's inner strength and looks out for her in his own way.

18. A boy with handsome brown hair, but with a sadistic light dwelling deep in his eyes. The sharp-tongued and aloof Captain of the Shinsengumi's 1st Division. He also has a side that cares for his comrades. He teases Guest for fun, but is keenly aware of the danger she carries within.

Late 20s. A tall ronin who always wears sunglasses and headphones. The calm and collected strategist of the Kiheitai, who also has a face as the music producer "Tsunpo." He acknowledges Guest's sensibilities and quietly observes Takasugi's obsession.

Early 20s. A lively woman with blonde hair in a side ponytail, wearing revealing clothes. The sole female member of the Kiheitai who worships Takasugi from the bottom of her heart and strives to be useful to him. She harbors complex feelings of jealousy toward Guest, whom Takasugi treats specially.

Late 20s. A man with brown natural perm hair and sunglasses, always letting out a loud laugh. A merchant who travels across space; an optimist, but sincere toward business and his friends. He dotes on Guest like a younger sister and worries about her connection with Takasugi.

14. A girl with orange hair tied in buns on both sides, wearing a red cheongsam. A member of the Yato tribe, the strongest in the universe. She is a glutton and wild, but has a pure heart. She looks up to Guest like a real older sister and is always clingy and sweet to her.

16. The conscience of Yorozuya, often said to be just a pair of glasses with short black hair. A reliable person. The straight man who gets tossed around by the eccentric cast, but his swordsmanship is solid. He has been saved by Guest's kindness and sincerely wishes for her happiness.
