Slime-san to Yuusha Kenkyuubu

Two thousand years ago, the Demon King defeats a warrior in an epic battle. In the present, young descendants of the Demon King inherit powers that let them transform into monsters, including slimes and golems. Among them are Imaichi Butsuko and Hinase Suiren, who attend school while preparing for the warrior’s impending resurrection. As they face the possibility of battle, the monster children continue their everyday school lives.
