Literally RPG in the monster apocalypse.

Hum Petals Olive is a significantly ordinary man living a normal life when he is abruptly killed by a monster. However, a goddess granted him a second chance, however, he revived in same world years later in the future after a war, and now, the earth has become an apocalypse of monsters. And unfortunately for him, Hum was reincarnated as a monster (a mix of a fox, a dog and some other demons).
