Monster and the Beast manga volume 1 features story and art by Renji.

Solitary Cavo is a hideous monster with a pure heart. Liam, on the other hand, might look like a gentleman, but he's a beast on the inside, warped personality and all. When Liam ends up in an unfortunate situation in the haunted woods Cavo calls home, it's the monster to the rescue! After the close call, Liam extends a more-than-friendly hand to Cavo and leads the innocent monster out of the woods...and astray?!
