The Legendary Demon Hero

Yuuki Ohma is dragged along in a mass summoning of students to a world known as Purgatory. A god named Yggdrasil tells them that they are heroes and that they will receive cheat abilities based on the unique attributes. Because I follow the tropes of course Yuuki doesn’t have any special ability BUT when he gets thrown out of the castle he inexplicably has the Demon kings blessing. So what will he do? Make a harem? Go on a mass murdering spree? Or maybe he becomes the new host of Saturday Night Live. I don’t know yet. I’m writing out of my ass
