Konosuba: God's Blessing on This Wonderful World!, Vol. 1 (manga) (Konosuba (manga), Band 1)

"Kazuma Sato is a game-loving shut-in--or at least he was, right up until a humiliating traffic accident brought his young life to an untimely end--is what you'd think. But after his death, a beautiful young girl calling herself a goddess offers him the chance to be reborn in another world. And so Kazuma's grand adventure to defeat the demon king begins--is what should have happened. But now he's been burdened with the useless goddess Aqua and the explosion-magic obsessed loli girl Megumin as they struggle to obtain just the basic necessities, doing nothing but hard labor day in and day out"--Back cover.
