Katsuki Bakugo, the arrogant and hot-tempered explosive hero from Class 1-A, actually has a twin sister! Her name is Chanthra and she was transferred to UA High because she was too advanced for her old school. Also Katsuki felt somewhat guilty about middle school and in shame didn't talk to Izuku for the whole summer before UA.

I own nothing but my original characters.  Also in this fic, the turtles and Master Splinter are humans instead of mutants. The four brothers are starting sophomore year they find it boring until they meet three girls that were the leaders of a popular group called the Elite Deck of Aces. And the leader is similar both to Raphael and Donatello in more ways than one. Their toxic ex friends are the bullies. Will they prevail or the toxic ex friends take them down and finally conquer the school? BTW, this fic takes place in 2019 despite being the human version of the 2003 Turtles.
