[Fun Fiction + Worldview Clash + Harem] That year, thanks to two hundred episodes of "Approaching Science," Rosser became a famous exorcist in Shinjuku. Initially, he just wanted to easily earn 100 million yen, then go back to his hometown to get married and never come to Tokyo again to avoid being beaten to death by his victims. But when the evil spirits actually came, and he blew up the school building with his made-up spells, he realized, "So I'm a god?" Rosser grinned maniacally. "In this world of evil spirit crisis, your savior has arrived." First, he'd transform into the Abyss-Eyed White Dragon, giving the world a little dragon-related shock. Then, he'd shift the blame, create a high-spec Type-Moon game, connect it with FGO next door, and whoever loses becomes a Lostbelt. Add some subspace, Cthulhu, and fight fire with fire... Crossover characters: Stop! And so... Goetia: Your Beast Law is... wait, what the heck is the Law of Cycles? Gudako: Mashu, could it be that our world is the Lostbelt? Anime Crossover World: Please, please, switch back to the evil spirit! I don't want the Cthulhu dimension! Sakayanagi Arisu: He didn't treat me like a cripple, nor did he treat me like a human being. Kazuma & Ayanokoji: Commander Rosser is my faith, my loyalty! Yukinoshita: Brother-in-law, won't my sister be angry if you do this? Tokisaki Kurumi: You scumbag god, watch me exhaust you with my three thousand clones!

Silently standing in a post-apocalyptic world of blood and fire, WarGreymon, its body mostly covered in pale yellow alloy, gazed listlessly at the sky, its expression one of indescribable sorrow and despair. Having traversed countless timelines, explored countless possibilities, and even reset existing timelines… even he, hailed as the “strongest hacker,” was now utterly exhausted. Even so, he dragged his weary body forward, clinging to that final glimmer of hope. “You want to protect the world…” “And I only want to protect you.” And so, in this desolate post-apocalyptic plain, only his final echoes reverberated across the battlefield of blood and fire. “Wait for me, I will definitely be with you to the very end!”
