The Silent Bookstore, a library perched on a small island in Cornwall, houses countless secret teachings and profound techniques. After a devastating fire, the entire bookstore was deserted and sealed off until a new librarian took office on a stormy day. Uesugi Sumi, a reincarnated individual, not only found himself in a world pieced together from numerous anime series, but also became a survivor of a shipwreck brought by the storm in another world. He successfully took over the Silent Bookstore, inheriting the library's resources and knowledge. To repair his bookstore, he decided to cultivate his own "tools" to make it easier to get freebies. Yotsuya Miko: He's a good person, though sometimes he doesn't seem quite human. Hikigaya Hachiman: A good person, but not entirely good; at least sometimes he doesn't seem like a good person to his friends. Goto Ichiri: A terrifying person, but very kind. Faced with these assessments, Uesugi Sumi, a master of nine arts, a master of initiation, a master of medicine, and an all-around worker, said, "Let's make friends... and get me a room while you're at it."

[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!

"Why can the doctor command immediately upon waking up?!" "Because he was once stationed in the Intercity." "Why does he know so much about firearms?!" "Because he had a broken nose." "Why can he use magic when he's not a magician?!" "Because he witnessed the freezing of humanity." "Why do we feel so familiar even though we've never met?!" "Because it's a long-awaited reunion." "Then why did he run away?!" "Because I'm not going to be the Doctor's Master/Commander anymore!" PS1: Crossover anime, Infinite, No Game No Life Zero starts here, see the volume title for the rest. PS2: Just so you know, there are absolutely no yanderes this time!

Lin Mo, a student at Zongwu High School, is a transmigrator from the Celestial Empire. He starts with the ability to reincarnate infinitely and can also absorb strange powers for his own use.

In this world that seems to be a slice-of-life anime crossover.

My name is Fujiwara Seiji, a transmigrator. What I love most isn't saving the world, but admiring the helpless yet beautiful sight of those arrogant heroines falling into the abyss. When the black-stockinged upperclassman, Kasumigaoka Utaha, took off her stockings in front of me for three million yen in surgery fees. When the blonde loser, Eriri, knelt down begging me to invest in her dreams. When the icy beauty, Yukinoshita, walked into my room to rebel against her family. Only then did I realize how interesting this world truly is. Hero? Savior? No, I just want to be a… behind-the-scenes mastermind who controls the heroines.
