Ep. 26: Kazane coordinates the assault on Leopard while Kagura confronts Nami and Xanthippe arrives to assist.

Kazane assigns Akiha and Honoka to attack Leopard’s brain with the Existence, while Kagura attempts to reason with Nami before defeating her. As Sakura and the Shishido elders disable the power supply, Akiha and Honoka enter Leopard, but a hyperspace rupture blocks their path. Xanthippe, Benkei, and Nerval arrive to stop the cannon fire. Benkei blocks the sun and removes Leopard’s Crown. Itsuki reunites Akiha with Imo-chan, allowing them to penetrate the rupture using Fon’s data. Akiha commands the Existence to attack the core, but Dark Leopard tricks her. After teleporting others away, Akiha defeats Dark Leopard by kicking through it, transferring it into Nerval. Nerval forces Leopard to destroy Dark Leopard. In the aftermath, Nerval survives, Kagura and Honoka require medical attention, Akiha is found by Leopard, Bou and Min beg Nina to stay, and Tsutsuji and Benkei depart with Nami.
