In This Chaotic World, I Just Want to Fall in Love

When the bright moon hangs high, the shrine bestows its blessing. When the devil turns back from the sea of suffering, time crowns the tombstone. The dead shall return to the world of the living... Ahem. To put it simply: The world of anime invades Blue Star. And Chen Yu, a good-for-nothing high school student, gets his first date with someone from another world: Wait! This silent, chubby shut-in... Has turned into a sunny young man and won over Miku from The Quintessential Quintuplets? So sweet, so sweet!! Nakano Miku is the best in the world! Hey, wait, why has the whole vibe suddenly changed? What! There's more! The perverted villain Yoshikage Kira is reborn as a housewife in charge of the cafeteria? The lovestruck high schooler Josuke Higashikata swears he'll be nothing but Miss Yae Miko's dog? A certain scumbag boss transmigrates, only to have his demon underlings rebel and leave him a lone commander?! Diavolo: Same here. You guys upstairs, let's huddle together for warmth! Doma: @Muzan, your only loyal subordinate has died. I'm currently chatting with you as a spirit... Medicine Seller: Are you also the old man in the ring? Doma replies to @Medicine Seller: I'm a handsome guy, and I can't turn my fighting spirit into a horse... Get lost! Readers: Oh my god! Stop, stop it! This world... Something is very, very wrong!! [Romance + battles] + [Reverse crossover with various anime] The synopsis doesn't do it justice. Please read the story. There are a lot of worlds involved, so please be patient at the beginning. The author isn't in a hurry, after all. If you like my humble work, please give it a five-star rating. It means a lot to me. Thank you! Though I cannot have the things I love, I can still enjoy them with all of you. (Blade: Please pay the licensing fee. Thanks.)
