That Time I Got Reincarnated as a Disappointing Prince

A young man who gets into a plane crash while returning from a business trip overseas is reincarnated into another world after being asked by the goddess to defeat the evil god.

However, he was reincarnated as a stupid prince who is known among the aristocrats as the "Pig Prince" because of his fat and ugly appearance. If you can't even do one sit-up, how are you going to defeat the evil god? This is the story of the Pig Prince's struggle to lose weight!
