Having spent his childhood in the slums, Hajime Shinonome desperately sought strength to survive. Now, he enjoys a peaceful and carefree life as a resident adventurer of the Komai Village. One day, during a quest, he ventured into a dungeon and finds a young girl being partially eaten by a weakest kind of monster, a slime! The girl's name was Lirui.
