Plot
A group of high school students are abruptly magically transported into the world of Eclair to the Kingdom of Distinia, which is being invaded by an army of demons. The king explains to the bewildered students that they have been summoned to become Heroes to defend the kingdom, and that this is the second time such emergency measures have been taken; five (of their) years ago, another "Hero" had been summoned, had ended the war and brought peace before he mysteriously vanished.

What nobody realizes is that one of the summoned students, Setsu, is that very same Hero. The problem is, because his appearance is different, nobody in this world recognizes him at first, so he has to reunite with his former comrades to save this world for a second time as well as uncover the mastermind behind this new war.
