Pigimaru

Pigimaru was once a small slime bullied by its own kind within the ruins of an abandoned site, until Tomori Hikaru stepped in to rescue it. Bound by that act of salvation, it became Hikaru's very first monster companion on his path of vengeance. Gifted with exceptional scouting and perception abilities, Pigimaru can detect lurking threats before they strike, and is even capable of merging with Hikaru through a 'Monster Enhancer' to fight as one—making it an irreplaceable source of both combat support and emotional strength.
