Rikuo and Kurotabo finally defeat Kidomaru, but their victory comes too late as Nue has already been born. Above the castle, Mamiru and Ryuji distract Hagoromo Gitsune to enable Yura and Hidemoto to seal Nue in his chrysalis. However, Tsuchigumo interferes with this plan because he desires to fight Nue. Rikuo rescues Ryuji from the chaos and engages in a duel with Hagoromo Gitsune. Meanwhile, Minagoroshi Jizo attempts to scare Tsuchigumo away using the Maō's Hammer to protect the sealing process. The group faces significant opposition as they struggle to contain the newly born entity amidst the ongoing conflict with the remaining antagonists.
