Buon Benectio

Five Guardians of the light, Kuroko's world stumbles when he learned that he has sisters, Kuroko Setsuna, his older sister and Kuroko Tetsuko, his older twin sister. However that's not what bothers him, but the certain truth that they weren't meant to be existed, and he must be protected. How will he manage to resume his 'seemingly normal life? . Again work of my imouto Yui-chan.
