Takatora Kureshima

"Those who own power and privilege have a duty they must fulfill. That's what Noblesse Oblige means. Sometimes you have to get your hands dirty in order to do that."

- Takatora explaining his importance to Mitsuzane

"Listen to me! You have to join with Kouta Kazuraba and save humanity! It’s all up to you, Mitsuzane!"

- Takatora telling Mitsuzane to save humanity, not knowing of his betrayal.

Takatora Kureshima (呉島 貴虎) is Kamen Rider Zangetsu (仮面ライダー斬月 [ザンゲツ]), later becoming Kamen Rider Zangetsu Shin (仮面ライダー斬月 真 [ザンゲツ シン]).

He is Mitsuzane Kureshima's older brother, who was a project leader in the Research and Development branch of the Yggdrasill Corporation until he finds out the company has been compromised, usurped by Ryoma. This causes him to team up with his old enemy, Kouta Kazuraba.

Past
At some point prior to the beginning of the story, Takatora was instrumental in testing the early prototypes of the Sengoku Driver. Though he suffered physical harm and scars from setbacks, he uses the Melon Lock Seed and a finalized Sengoku Driver prototype to become Kamen Rider Zangetsu to deal with the Inves in Helheim Forest. Despite his questionable methods, his intentions are well-meaning, proven from the fact that he instructed Ryoma to lower the specs of the Sengoku Driver to facilitate easier mass production, so to save more people, instead of hoarding power to himself.

Beat Riders Saga
Takatora is seen throughout the Beat Riders Saga as the protector of the Helheim forest, protecting his men as they forage into the forest to harvest the Helheim fruits. During one of these expeditions, he battles Gaim and teaches him the cruelty of reality and that the Sengoku Driver isn't a toy.

During the events of the movie, Takatora finds three of the Sengoku Driver users have gone missing. Enter the Sengoku Period World, he accidentally defeats Bujin Double before realizing that he helped Bujin Gaim, a different Gaim than the one he is familiar with. He later picks up the Joker Memory, the remnants of Bujin Double. As Zangetsu, he gives Ryugen the Suika Lockseed to ensure that the Sengoku Driver users return safely to their world. When the Priestess of Fate arrives, he realizes that the remnants of the Bujins resonate with the immature Lockseeds that was left in the girl's wake. Creating the Fourze, OOO, Double, and Wizard Lockseeds, he aids his fellow Riders, assuming the Fourze Arms, defeating the Nepenthes Inhumanoid together. In the aftermath, Takatora appears to have a prototype Genesis Driver and Melon Energy Lockseed.

Takatora later appears during the Lockseed gathering game, causing all 7 prototype Sengoku Drivers to appear in the forest. Takatora defeats Gridon, Baron, and Bravo without breaking a sweat, but in a rage, destroys Kurokage's Sengoku Driver by accident. He returns to Headquarters unpleased that Gaim saved his men, calling him street trash.

With all the data feedback from all 7 prototype Sengoku Drivers, Takatora uses the completed Genesis Driver to take out multiple Kurokage Troopers, noting that the Genesis Driver is powerful.

Yggdrasill Saga
After the development of the Genesis Drivers and his new transformation into Kamen Rider Zangetsu Shin, Takatora deems the Beat Riders to have outlived their usefulness. After learning that Mitsuzane was made an Armored Rider behind his back, Takatora shows his younger brother the ruins in Helheim Forest to convince him to help him for the greater good. When meeting Kouta and showing him the ruins, Takatora sees the same ideals he once embodied in the youth and it only makes him more adamant to crush Kouta's spirit. He succeeds when he reveals to Kouta that in his first battle as Armored Rider Gaim, he killed his friend Yuya Sumii who had been transformed into the White Tiger Inves. However, Takatora later is shocked that the revelation has the opposite effect on Kouta, who destroys Yggdrasill's Scalar System.

Helheim Saga
After Mitsuzane reports to the group that DJ Sagara is helping Kouta, concealing the full story of the Overlord Inves, Takatora does not believe these turn of events at first. However, Takatora learns the truth when he confronts one of the Overlords leading an attack on the research team with Kouta informing him of how the type of Inves may be instrumental in stopping Helheim Forest's expansion. Seeing a way to stop the invasion without massive sacrifices, he decides to ally with Kouta to stop the Overlords. However, Takatora is oblivious to the fact that Ryoma's group is conspiring against him. This becomes Takatora's downfall as he is usurped by Ryoma's group and loses his Genesis Driver while being subsequently thrown off a cliff. Eventually rescued by the Overlord king, Rosyuo, Takatora learns the origins of the Femushinmu. Now realizing Ryoma's ambition, he realizes what Ryoma meant by him never understanding what he worked for. To his dismay about humanity being able to be saved, Rosyuo delcares that humanity is foolish and will not ontain the Forbidden Fruit to repeat the tragedies that happened to his civilization.

Personality
Though a ruthless realist, Takatora still loves his family and spoils his younger brother, and especially cares about Mitsuzane's education. He is the most experienced and most powerful Armored Rider to date. In order to teach Gaim a lesson, who entered the Forest without his permission, without knowing that he's only looking for his friend, he brutally attacks him despite Kouta having no intention to fight him to make his point - that power given by the Lockseeds and Sengoku Driver is no game, letting Kouta go after clearly being the winner.

Despite his sense of realisim, he can show signs of arrogance and his wealthy upbringing has mildly affected his view of the world. He sometimes refers to the other Armored Riders as "street trash" that are beneath him and not worthy of his attention, the exception being if they directly interfere with his plans.

He also seems to have a bit of a temper when pressured, as seen when Kurokage provokes him while he was trying to reach his staff to rescue them from the Inves swarm. This caused him to have an angry outburst and unintentionally damage Ryoji's Sengoku Driver with a furious blow of sword slashes.

As stated by him back when he first encountered Gaim, he knows the Lockseeds carry a dangerous disease, which is also seen when he tries to warn Hase not to eat the immature fruit.

Under his ruthless realist personality shows that Takatora does have hidden feelings, grieving that he is only able to save about a billion of the Earth's population. More of this side is shown when he takes care of Oren after Oren takes a hit that disrupts his transformation as he falls into his arms. In addition, he finally lightens up, handshaking Kouta and thanking him for giving him an alternative means to save humanity rather than culling the world's population through Project Ark.

His ruthless realist personality was in fact used under the influence of Ryoma when he realized his own friend had been using him all along prior to his betrayal.
