Serious version: Everything will eventually come to an end. The temple's glory, the assassins' annihilation, churches rising everywhere, and a demon in white lurking above them all. Everything is for the so-called Eden Relic. The temple once used it to enlighten and control the people. The assassins, however, wanted nothing but revenge! The last assassin left in the world, the only one who knows where the relic is, lives a seemingly peaceful life on campus.
Normal version: After successfully taking revenge, an assassin returns to an ordinary life. But he discovers he has no idea how to communicate with people, and somehow gets caught up in one mess after another.
