I think this anime is like a decade old or something? It isn't isekai per se, because it takes place in a place like a parallel Earth with magic. It takes place in Japan of course. Basically that world has magic and they even have a prophesized Maou or Demon King. This dude actually wants to become a figure of Good, like a pope or something, but he ends up being the Maou. The prophecy was made on his first day at school (by a talking bird living in a jar) and causes lots of misunderstandings for him. In the first episode, the MC meets a girl called Junko or something. She's from some magic samurai family who has sworn to defend the empire etc. Another character is a flying girl who can turn invisible. She likes rice a lot iirc. Does anyone know the title?
