On his way back from the convenience store, Daiki suddenly gets caught up in a different world summoning.

In front of him was a throne and the high school students who were probably summoned together.

…high school student?

Daiki, who is a little older than them, seems to have just gotten caught up in their summoning, and is expelled from the castle, saying, ``I have no business for you.''

Even if high school students are told to stay in the castle town until they save the world...

I don't have the strength, I don't have the knowledge, I don't have any skills and I don't have anything to do...What should I do now?
