After dying in a fight against the forces of evil, a knight found himself reincarnated as one of the most powerful monsters in the world: a behemoth! Problem is, he has to grow up before he can really strut his stuff, and a baby behemoth looks an awful lot like…a housecat?! And when an elf adventurer decides to take him in, she may need his help as much as he needs hers!

Long ago, the most ancient of divine dragons was slain by a human. The mighty dragon accepted its death when suddenly, it was reborn as Dolan, a man who lives in a quiet village. While spending another peaceful day toiling in the fields, he meets Celina, a half-human, half-snake creature looking for a partner. The unlikely duo become friends, but challenges lie ahead that threaten their new bond.

Hinako, a high school student with a dark past, lives alone in a town by the sea. Haunted by a constant sensation of drowning, she can barely go through the motions of her tedious life…until the day a monster tries to eat her! After passing out in the struggle, she awakens to find she's been rescued by a beautiful mermaid. However, salvation comes at a cost—the mermaid's protection will last only until Hinako has matured into the perfect meal! Hinako's first instinct isn't to run or scream, though, and an unlikely relationship between monster and prey unfolds… "I've come to devour you."
