Jigoku Mushi wo Kuu! Oninbo

Oninbo is a demon with unrefined eating habits, favoring a diet of grotesque creatures known as Bugs from Hell. These bugs reside within human hearts, growing increasingly repulsive as they feed on their hosts' souls. Oninbo can detect them from a distance and will go to great lengths to capture them. He faces competition from Mamushinbo, another demon with a taste for the same prey.
