Shigeru Sugiyama (a cafe assistant), suddenly teleports to a fantasy world, where he realises he is different from the rest. However, this wasn't in a good way. The younger high school students who teleported to the same world had titles of [Heroes] and [Saints], but Shigeru didn't have any titles to his name. But then it happened again. Shigeru teleported once more, but this time, to the real world!
