Anime Crossover: I Never Meant to Become a Big Shot

Earth's resources ran dry, and the world fell into an unprecedented crisis. Conflict, plunder, and chaos engulfed everyone in endless war. The global population plummeted, and the survivors struggled to stay alive, with only death awaiting them. At the brink of despair, a miracle descended. “Become a Contractee, and you will gain everything. The Starry Paradise can do anything.” Those summoned by the Paradise boarded the space-time tunnels full of hope, only to find themselves in anime worlds that had once existed only in their imaginations: Kabaneri of the Iron Fortress, Attack on Titan, Demon Slayer... These worlds were terrifyingly real and terrifyingly dangerous. Some survived, but many more were lost forever. The lucky survivors became Contractees, exchanging resources with the Paradise and helping Earth just barely weather the crisis. From then on, the world could never escape the Starry Paradise's control. Everything depended on the “equivalent exchange” between the Contractees and the Paradise. Qin Chaoyan, who lives in the slums, resolutely accepts the summons and enters the Starry Paradise to find the younger sister who is all he has left. He does ordinary things with the bearing of a great expert. Qin Chaoyan: “I really didn't do it on purpose.”
