Hellhound

From Jenny Everywhere Wiki
Jenny's human date telling her about his encounter with a Hellhound.

Hellhounds were demonic beings in the Seventh Circle of one universe's Hell. In anticipation of one Valentine's Day, Jenny Everywhere's human date sold his soul to a “minor” hellhound in exchange for a copy of the Plasmanomicon to gift to her. (COMIC: My Bloody Valentine)
