Accidentally entered in infinity castle by Muzan

Nova, the enigmatic transfer student whose touch turns boys into frogs - literally. Her life's a living nightmare until she meets Alex, a heartbreaker turned friend on a bet. But as they navigate through pranks, he finds himself wanting more than just a wager. Campus drama brews as their 'friendship' sparks rumors hotter than the chemistry lab's Bunsen burners.

At that time, Azim want to meet kagaya cause he is the best friend when we're child. Azim arrive with the ship and more crew pirates. Azim is the yonko in ocean, i mean Azim is dangerous pirate cause Azim have haoshoku haki. Azim and another pirate moved realms and entered the realm of infinity castle. There Muzan was waiting for hashira to kill him. Kagaya already dead cause he got dead cursed...

Mitsuri loved AzimBoek long before her confession after the battle against Muzan. She was not able to confess though, as her trauma from her past marriage interviews held her back. She would sometimes ask Shinobu for love advice, but due to both of them being oblivious to love, their exchanges mostly became weird.
