Anime Crossover: Starting with an Armor Summoner

GBC, Bocchi the Rock!, K-On!, MyGO!!!!!, Gabriel DropOut, Love, Chunibyo & Other Delusions, My Youth Romantic Comedy Is Wrong, As I Expected, Oreimo, Saekano, The Quintessential Quintuplets, The Girl I Like Forgot Her Glasses, Kaguya-sama: Love Is War, Miss Kobayashi's Dragon Maid, A Silent Voice, Himouto! Umaru-chan, Chuunibyou, Rascal Does Not Dream of Bunny Girl Senpai... tentative list Multiple heroines; the romance is a slow burn If you transmigrated to a crossover anime world and had both an armor transformation and the Sharingan, what would you do? Chen Xuanyuan says he'd obviously become an Ancestor One. Wait... why are there angels in an everyday world? Never mind. They dared to mess with me, so I'll beat them up first! Parasyte? Beat them up! Ghouls? Beat them up! Muzan? Beat him up! Uchiha Madara? Beat him up! Hang on, something's wrong. Forget this not being an entirely ordinary world, it's supposed to be a city! Why are there ninjas here? I don't want to be an Ancestor One anymore. I just want to play games in peace, all right? Why are so many girls bothering me? I don't even want to start a band! Gabriel: Chen Xuanyuan! Come help me clear a dungeon. Hitori Gotoh: Here's today's friend fee. Please accept it, Lord Xuanyuan. Tomori Takamatsu: Please form a band with me for the rest of our lives. Rikka Takanashi: In the name of the Wicked Eye, I hereby enter into a contract with you. Subaru Awa: Xuanyuan, can I borrow Hiei to play with him again? Kuroneko: One-on-one in the arena! Don't run away! Nijika Ijichi: Xuanyuan, I can transform into armor and fight alongside you too! Chen Xuanyuan: Ahem, Nijika, I think you'd be better off using the power of the Nine-Tails. How about Uzumaki Nijika? Namikaze Nijika works too. (Just kidding.) This story leans toward everyday life in a crossover anime world. There are battles, but the focus is still on daily life.
