Byoki no Oni

Byoki no Oni is an infectious oni covered in pus and mucus. The goal of Byoki no Oni is not to fight attackers, but spread its infection. The oni can spread its disease by a single touch or spattering blood and pus. If not treated within three days by a purification ritual, the infection will turn the victim into a plague zombie. These zombies are also covered in sores that carry the disease and pus.
