what happened was that yamamoto was training with the rest of the guardians by cutting through wood. hibari tested the wood and either thought it was to boring or to easy. so he wrapped up a human. he chanted "human human" to get yamamoto to cut through him. he said "guess it cant be helped" because he didnt want to disappoint hibari so he thought he had to kill the man. i dont really see the point in this extra story, but i found the main story cute. anyway, thanks for putting it up!!!!!
