I, Midorimu Sakaki, was born with a talent for life magic, which cannot be used for dungeon exploration or defeating demons. It is the highest rank S. I was working as a clerk at a magic academy while being scorned as useless, but by chance, I came into possession of a rare item "Sage System" that allows me to create new magic during dungeon exploration. I used the system to create life magic for dungeon exploration, and finally took my first step as the adventurer of my dreams...!
