Yuusha Party wo Tsuihou Sareta Ore daga, Ore kara Sudatte Kureta You de Ureshii. ...nano de Daiseijo, Omae ni Otte Korarete wa Komaru no daga?

Written off as nothing more than a useless bag boy, Mihama Ariake is driven out of the hero’s party he had been traveling with. However, his true strength is in his unlimited use of all extant skills, a power directly bestowed upon him by God—and it is God’s will that he use those skills to back up the hero’s party. Freed from that duty, he goes where his whims lead him, running into many surprising people and unexpected things along the way. Based on a wildly popular novel published by Square Enix, join Ariake as he and his invincibility carve out a new path!
