Kikuru Madan, the strongest hunter in the Mebuki Town Guild, is worried that he is wasting his youth hunting monsters. He plans on retiring from his current line of work in order to pursue college and relationships, but the guild receptionist, Enome, convinces him to go on a quest with a new martial artist named Hitamu Kyan. However, Hitamu proves to be unskilled in fighting monsters and is attracting them instead with her mana, which causes them to latch onto her in erotic ways. Kikuru decides to put his retirement on hold to train her and the others who join the party so that they can succeed him.
