Three years ago, the Hero Shion sealed the Hell Gate. The Seal has been weakening ever since, sporadically letting monsters through. After a big group of monsters entered the country through said Hell Gate, Heroes were needed again.

Touka Scott, a radish farmer and trapper in the southern town of Cheza, lives a peaceful life with his beautiful childhood friend and neighbor Yuna, but he is nevertheless prepared for sudden monster attacks. He built himself a hidden pit-trap with bamboo spikes to lure unsuspecting monsters if they ever try to attack the village. A monster attacks and Touka fails to lure it into the trap with freshly roasted bacon. Thankfully, the local Hero saves the village from the monster in the nick of time. The hungry Hero tries to grab a bite of bacon after vanquishing the monster, only to stumble into Touka's pit-trap and die.

After causing Shion's death, Touka is reluctantly forced to take matters into his own hands to protect the region from attacking monsters… by occupying the late hero's body!

Accompanied by Yuna and the necromancer girl Anri (who forced him into Shion's body), together they set on adventure… and to save face.
