The only thing I remember about this story is that Sesshomaru teaches Shippo to hunt (and the story is not Imperceptible). Sesshomaru is traveling with the group and teaches Shippo to hunt. They first hunt fish then bunnies where Sesshomaru teaches him to skin his catch. Shippo's first attempts were bad because I remember Sesshomaru had to catch extra. When Inuyasha complained about Sesshomaru's teaching, saying that he had learned on his own by watching Sesshomaru. Sesshomaru replied that he had known Inuyasha was watching when he was young and had displayed proper technique in an attempt to teach Inuyasha.
