    What happens when you have built your whole worth with how much you achieve? What happens when you achieve nothing as time goes on? You succumb to the belief that you're undeserving of everything nice in the world. That is.. until you meet the sadistic red-head, who makes you feel as if you have everything in the world by merely offering you a smile. And suddenly, you see the beauty of things outside of the scientific scope. [🚫🚫DISCLAIMERS🚫🚫] - I do not own Assassination Classroom, nor do I own any of the characters mentioned (except Reader). - I am not a professional, I am just a massive science obsessed freak. - English is not my native language.

    Karma was seven and just wanted some cake. "Karma!" Gakushuu yelled, chasing after him and starting to catch up. "Get back here!" "I want cake!" Karma yelled, running faster when he saw the person up ahead start to turn a corner. "I'm hungry-huh?" He frowned when he saw a large hole up ahead and tried to slow down. "Wait-" "I said, stop!" His older brother caught up and tackled him, sending the two of them down the hole and into the abyss. Now somehow they'd ended up in a fantasy world that had Demon Kings and witches with large cleavage. Pt 7 That universe where Karma and Asano are brothers and everyone else suffers because of it.

    This is a Assassination Classroom AU, Koro-sensei is still a yellow octopus ? Korosuma ans professor bitch are there as well. The thing is that Nagisa is an assassin and know one knows even korosuma, he is known as the devils child for his age and being the best assassin. Korosuma is suspicious as well as a certain red head. The only reason Korosuma Dozent know how s because know one knows the devils child's gender. Can Nagisa stay under cover or will he be discovered Disclaimer I sadly do not own the series but the cover for this book is my own work. (As of rn its not but I'm to lazy to remobe thus part :]) I might add characters from other anime's later on. There will eventually be yaoi yay!!!! Ps Nagisa mom is the same but she doesn't know that he is an assassin, he is depressed and there will be triggering moments I will warn you abt the beginning of the chapter Kay... Kay lets reas the story!!!!!!!!!!!
