Rookie jailers assigned to the Hell of the Unpleasant Place. Originally Momotaro's companions: the dog (Shiro), the monkey (Kakisuke), and the pheasant (Rurio). The trio's name comes from that.

In modern terms, he suggests that rewards greater than a kibi-dango are plenty. Rurio: A pheasant wearing lapis lazuli beads. The most calm, collected, and hardworking member of the team.

Obsessed with his achievements in life, he came to Hell with the Momotaro Brothers to pick a fight even with the ogres of Hell, but was easily defeated by Hozuki and subsequently reformed.
