Lake, whose only skill is "curse dispelling," is denounced as useless by his party members, cast out of the party, and abandoned deep inside a dungeon. Stranded all alone in a dungeon teeming with monsters and facing a desperate situation, Lake somehow manages to stumble into a hidden room...

When he immediately uses his curse-dispelling ability on it and equips the ring, a beautiful silver-haired girl named Miu emerges from it...! (Source: Hifumi Shobo, translated)
