KuroFuri: "CAMERA" (mah friend's)
One time, Furihata bought a very expensive camera. He brought it to school and everybody from the basketball club flocked around him. And when they started fighting over it, Furihata asked Kuroko to stop them because they might break it. Of course, nobody noticed Kuroko so he decided to use Ignite Pass Kai and sent the camera crashing on the wall, breaking it into pieces.
Furihata ran to his camera, crying over the loss of his precious camera. When Kuroko came up behind him to apologize, Furihata was startled, turning around, losing his balance and falling down. His butt landed on the shards broken camera and some of the sharp pieces were pierced inside his butt hole. He stood up and there, Kuroko saw a very large piece sticking out from his ass.
"I'm really sorry, Furihata-kun." He said calmly but sincerely while Furihata kept running around, screaming in pain. To make it up to him, Kuroko took another large and sharp piece from the pile and thrust it up his own ass. "See, now we're even" Kuroko said.
"That doesn't make me feel any better." Furihata cried. They were sent to the hospital to be treated. All that time, Kuroko only had a pokerface while the piece was removed from his butt which creeped Furihata and especially, the doctor out very much.
