I'm Izumi Natsuhiko, and I can't get hurt or die.
But that's not important. What's important is that I have a super-reclusive little sister,
a close female friend who loves gaming so much that she got into a legendary school by playing games,
a cold-as-ice club president in a club I was forced to join by a teacher who was past her prime,
and a chuuni neighbor who just moved in and climbs down from her room on a rope in the middle of the night.
When unexpected events change our unchanging daily lives,
the bonds forged through all kinds of experiences gradually bring us closer,
while revealing the truth of the world and the secrets of my own existence.
A demon king on earth who slays gods, an immortal god who has imprisoned himself in myth, an ultimate weapon that devours souls, visitors from other worlds, supreme beings
countless worlds intersect here, giving rise to dazzling possibilities...
