Brothers' End! Zangetsu vs. Zangetsu Shin!

Brothers' End! Zangetsu vs. Zangetsu Shin! (兄弟の決着！斬月VS斬月・真) is the thirty-sixth episode of Kamen Rider Gaim. It features a showdown between Takatora as Zangetsu and Mitsuzane as Zangetsu Shin.

Synopsis
As Mitsuzane/Zangetsu Shin is about to kill Kouta, Takatora appears and stops him, revealing the two's relationship as brothers to Kouta. Later, the fight of the two brothers begins as Takatora returns as Zangetsu to fight Mitsuzane.

Plot
With Mitsuzane as Zangetsu Shin canceling Kouta's transformation, Takatora intervenes to dissuade Mitsuzane from siding with the Over Lords. Kaito also attempts to aid Kouta, but is attacked by Redyue and is affected by flora growing on his wound. Kouta explains to the rest at Team Gaim's hangout about Mitsuzane's betrayal with Mai in disbelief, believing that Mitsuzane lied to everyone so that he could be their friends. During this chat, Takatora learns what happened of Yggdrasill after Ryoma usurped it. He forgives Yoko and goes to find Kouta, telling him of his origins with Mitsuzane and how he had to raise him alone, much like how Akira Kazuraba had to raise Kouta alone. Takatora, believing if he was more like Kouta, Mitsuzane wouldn't have become the way he is. Entering the abandoned Kureshima residence, he regains the Sengoku Driver and Melon Lockseed. Meanwhile, Redyue toys with Mitsuzane telling him that killing the people you trust and betraying their trust is an exciting feeling. Mitsuzane is prompted by Takatora on the Yggdrasill Mainframe to meet with him. Kouta, searching for Takatora, is unable to find him and can't initiate their plan to save the captured citizens of Zawame. Takatora tells Mitsuzane that he is his shadow and that all the mistakes he made is reflected on Mitsuzane's mistakes. Takatora and Mitsuzane both transform and the fight ensues. Kouta finds Redyue and realizes that Redyue is manipulating Mitsuzane. Injuring Redyue, Kouta unleashes Kiwami Arms and overpowers her to the point where she realizes that he's becoming an Over Lord and that Kouta possesses the powers of the Fruit of Knowledge and retreats. Flashing back to the Kureshima Brothers, despite using the weaker Sengoku Driver Takatora has the upper hand against Mitsuzane. However when the time comes to land the final blow, Takatora flashes back to how he cared for Mitsuzane when they were children and finds himself unable to finish off his brother. Mitsuzane, on the other hand, shows no mercy and takes advantage of Takatora's moment of weakness by slashing at a point-blank range with a Melon Energy Squash, which destroys the Sengoku Driver and sends Takatora flying into the sea as his helmet shatters. As Takatora's suit dissolves and he disappears into the depths of the ocean, his final thoughts are of Mitsuzane.
