Yuusha Shoukan ni Makikomareta kedo, Isekai wa Heiwa deshita

When you get summoned to another world, things are supposed to go a certain way: become a hero, battle monsters, and slay demons, right? But when Kaito gets his summons, things are a little different. First off, he’s not even the hero…but it doesn’t matter, because the world he’s been thrust into is at peace. With nothing better to do, Kaito finds himself taking it easy in this unexpectedly mellow fantasy world. Now he can breakfast with its beautiful denizens, learn magic with the help of a spunky demon girl, go to barbeques, and so much more!
