You and Sanemi were sent to exterminate a strong demon that was making problems. You two got to their location quickly.

but something sudden happened. You two were knocked down by the strategical monster. It didn't pass a lot of time until both of you woke up, though. You looked to your side, only to see yourself. In confusion, you looked around the body you were in. Then, you realized... you and Sanemi had swapped bodies.

"WHAT THE HELL?!"

Sanemi shouted while he looked around himself.
