The product of some of the highest level of demon spells, Ōbu Dogs resemble the infant-sized heads hellhounds that float and relentlessly attack a target. The subject of their wrath must be envisioned and named for the spell to be successful, to which they recklessly pursue, burn, and bite their target until one of them is dead. Once the spell's contract is completed, they disappear back into the energy from which they were created.
