After graduating from high school, Tetsuya Kuroko, a transparent boy who was a sensation in the basketball world, suddenly quit basketball. Since then, he parted ways with basketball, and because his personality was at odds with the career his parents wanted, he had to change his personality.
He thought he would never see basketball again in the rest of his life, but unexpectedly, he was given a chance to rewind.
The original teammates, the original Teiko High School, the original team uniforms... But everything is different, things have changed. And... What's going on with the clothes! Although his appearance has not changed much, but! Why is my past self also in this place?
Isn't this a bug?
Could it be... In fact, this is not rebirth!
