Plot
InuYasha and company arrive at a special tree that has recently started absorbing people again, and they find that it has a Shikon shard. What's more, it's guarded by Naraku who proceeds to absorb the tree and escape. Meanwhile, Koga is trying to track down Moryomaru and instead runs into Kikyo and Kohaku. Kikyo wants Koga to give up his shards so that she can go through with her plan, and she points out how the shards in his leg haven't been obeying him. Koga, however, refuses to give them up and continues after Moryomaru. At around this same time, Moryomaru has run into Naraku, and he appears to win the ensuing battle and consumes him. With most of the Shikon jewel now, Moryomaru's next goal is to go after the remaining shards, and, watching from nearby, Kagome realizes that this means the ones attached to Kohaku and Koga.

Both of them are nearby, and Koga is the one Moryomaru targets first. Koga and InuYasha try to work together against Moryomaru, but they're not able to accomplish much, and Moryomaru stills captures Koga. The problem for Moryomaru and Akago is that Naraku starts to take over Moryomaru's body, he uses the tree's special ability to break through Akago's barrier. Naraku eventually succeeds, and in order to free Koga, Kagome fires an arrow at him. As a result, Koga is able to break free. Miroku opens up his Wind Tunnel to suck Naraku in. Unfortunately, this means that Miroku also takes ton of Naraku's Miasma, putting his own life in danger. Miroku is able to suck in the Fuyoheki, but because of the danger, InuYasha closes the Wind Tunnel before Naraku himself can get sucked in, thereby allowing him to escape him to escape. In the aftermath, Miroku is barely still alive and Kikyo tries to treat him.
