A daring group of individuals called "Adventurers" set out on challenging expeditions to overcome various powerful monsters. These Adventurers are grouped according to their distinct combat abilities, such as Fighters or Monster Users. Keel, one such Adventurer, embarks on a quest to find the legendary monster-slaying specialist, Shiva. It is rumored that she is the best at defeating the fearsome S-ranked monster, Dragon Ape, and has taken something valuable from Keel. On his journey, he meets Ravi, another Monster User, and her trusty companion, Mippy. Upon receiving advice from a townsperson, Keel decides to join forces with Ravi with the goal of discovering the whereabouts of Shiva.
