Tensei Saki ga Zannen Ouji Datta Ken ~Ima wa Fukkin 1-kai mo Dekinai kedo Yasete Isekai Sukuimasu~

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 (Orc 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?
