Short Summary
Inuarashi explains the antagonistic relationship between him and Nekomamushi, the master of the Whale Forest. Back in the past, Inuarashi and the Musketeers arrive to battle Jack, with Inuarashi succeeding in holding back one of Jack's attacks, but are forced to retreat due to the sun setting.
