Be Kazuma

(You're expected to have watched Konosuba in order to know what is going on)

Aqua: aw, poor thing.

Kazuma: what! Where am I!

Aqua: you died, welcome to the afterlife.

Kazuma: i died! Right. I remember now, a girl was going to get hit by a truck, and I jumped in the way to save her, is she ok?

Aqua: is that how you remember your death?

Kazuma: yes, why?

Aqua: *She laughs *

Kazuma: what's so funny?!

Aqua: nothing. Yes, the girl lived. Anyways I am the goddess Aqua, and I am going to reincarnate you into another world, one under threat of a demon king, and if you defeat him I'll grant you one wish, you may pick one item or ability to take with you on your quest, choose wisely.
