KONOSUBA -God's blessing on this wonderful world!

Kazuma Satou decides that today is the day to get out of the house for a bit. Since he dies, pointlessly, it's clearly a bad choice. The goddess who greets him in the afterlife, however, offers him a chance to be reborn in a world not unlike that of a video game, and as a bonus she'll even throw in a cool item or power! Can't possibly be a bad choice, right? Except he arrives with no money at all, dead average skills, and his "bonus" isn't useful at all--since he picked the goddess, Aqua, herself.
