When seasoned swordsman Alec Deer takes on a quest assigned by his old pal and local guild leader Zack Ciel, he anticipates a challenging journey: enduring the wilderness for weeks, battling monsters, harsh terrains, and maintaining team morale. However, Zack assures Alec that the manticore mission will be swift and successful, thanks to the aid of Shiori Izumi—a unique B-rank support mage under his wing. Despite her seemingly modest magical abilities, Shiori's talent in blending elements and casting precise spells sets her apart in the realm. Known as a 'housekeeping mage,' she effortlessly enhances the adventurers' comfort on the road. Despite her amiable nature, Alec perceives a hint of loneliness in Shiori, unaware of the deep-rooted reason behind her isolation.
