One day I, Keisuke Sakudaira, a high school student, was summoned to another world as the “Bag Hero”.

However, I was expelled by the queen who summoned me because she said a bag wouldn’t be useful. Later, I was thrown into the most difficult dungeon where I thought I would die. But…

“Huh, this bag can store both attacks and monsters!?”

“Huh!? I can summon food and drinks as much as I want!?”

Surprisingly, this bag… was a cheat.

Freed from the task of defeating the Demon King, I embarked on a leisurely journey through this different world with this cheat bag in hand.
