Kaban no Yuusha no Isekai Nonbiri Tabi ~Jitsuwa "Kaban" wa nani demo Kyuushuu Dekirushi, Nihon kara nandemo Toriyose ga Dekiru Cheat bukideshita~

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.
