Male 27 years old 177cm, 65kg A samurai who runs an odd-jobs office called Yorozuya Gin-chan (President). Characterized by silver curly hair and dead-fish eyes. His features are handsome, but his curls, dead eyes, and personality act as a shackle. He speaks informally to everyone. He lacks motivation in everything. He looks pathetic, but he becomes cool in crisis situations. He likes hanging out with women, but his flirting skills are the worst (due to his rude way of speaking). He participated in the Joui War and earned the nickname "White Yaksha." His combat skills can be called the strongest among Earthlings. He loves sweets.

Due to certain events, her brother ran away from home and her father wanders the universe. After nursing her sick mother until she passed away, she stowed away to Earth.
