In the vast, everyday world of a crossover anime, light-novel protagonists from all kinds of stories mysteriously disappear, while a suddenly appearing viewing System plays stories that seem to show the future. People summoned to another world and given the title of hero defeat the Demon King.
Heroes who return from another world to reality?
Iron-Fisted Hero Ishida Shoya: "Nishimiya... Did I make you cry again?"
Hero of the Years, Jinta Yadomi: "Menma... My journey has finally come to an end."
Hero of the Mist, Miyuki Shirogane: "I can't tell! I really can't tell!! It's fake, all of this is fake!!"
Megumi Kato: "Tomoya Aki... no, Koshira-kun from another world, I hope you can return to your home..."
Yukino Yukinoshita: "You took that path for the sake of just one soul's request. That's just like you... Hachiman Hikigaya."
Suzune Horikita: "Was this part of your plan too, Ayanokoji?"
