[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!

Bad news: Chosen by a death game, forced to participate in terrifying dungeons. Good news: Transmigrated to Gensokyo five years ago, not only building relationships with various characters but also becoming the young master of the Yakumo family. Death game? No problem! I have a bunch of old... ugh... a bunch of big shots behind me!!! ...Encounter a strange mermaid? Release Kaguya! Chased by a creepy little demon? Release Kaguya again!!! Strange knocking on the bathroom door late at night? Release Kaguya again!!! Kaguya: You... encounter a cold and arrogant fox spirit player? Hmm? It's even the same world. Runs home, finds his own Ran, points to a photo: Yes! That's her! ...Bai Liu: Want to make some money? Lots and lots, the kind you can't spend all of. Reimu bangs on the table: Please accept the shrine maiden's bow! ...[Two books guaranteed to be completed within a million pages][This author has transmigrated through dungeons, not just writing randomly] PS: As I said before, this author is going to become the god of Gensokyo! One book isn't enough, so I'll write three; three isn't enough, so I'll write five; five isn't enough, so I'll write ten. As long as I don't starve, I'll keep writing. Damn it!!!
