Kaito Takagi

Kaito Takagi was once an ordinary high schooler scraping by in the dungeon by hunting slimes. Everything changed when he unexpectedly defeated a golden slime and obtained an exceptionally rare Servant Card, allowing him to summon the mighty battle maiden Sylphy. With a newfound dream of becoming a hero, he pushes forward through the dungeon's many floors alongside his Servant companions, growing stronger through relentless effort.
