"Stormbreaker," an up-and-coming party of young adventurers, is making waves in the dungeon conquest world with its record-breaking speed.

However, the other members have no intention of kicking him out. In fact, they are the complete opposite...? Is the negative handyman actually a genius(?) support mage?
