I do not own Kuroko no Basket, nor do I own its characters. Also the story is different form the manga, because instead of Seirin winning against Rakuzan they lose. After being betrayed by his team and his light. Kuroko realizes that he can never relay on anyone. Especially a light. From that moment on he decides that in order to continue doing what he loves he has to become stronger. Strong enough to dominate any light that stands in his way. He is the Shadow the will conquer all.
