Takatora Kureshima

"Yggdrasill holds the fate of the world in its hands. I will secure humanity's future."

- Takatora explaining his importance

Takatora Kureshima (呉島 貴虎) is Kamen Rider Zangetsu (仮面ライダー斬月 [ザンゲツ]) later 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 is a project leader in the Research and Development branch of the Yggdrasill Corporation.

Origin
At some point prior to the beginning of the story, he was given the Melon Lockseed and a Sengoku Driver, enabling him to transform into Zangetsu.

Helheim Forest Investigation
Takatora was first seen as Zangetsu, rescuing his men from the a bunch of Elementary Inves during their investigation in the Helheim Forest. He later appears in his normal identity in a company limo watching the broadcast about Armored Rider Gaim before taking out his Melon Lockseed while issuing the order to investigate Helheim Forest.

His brother education
As Mitsuzane secretly walked towards his room, Takatora asked him why he came home late. Mitsuzane replied that his cram school was doing extra sessions. Both of them have a conversation as Takatora reminds Mitsuzane to cast away any distraction that may disturb his education. Mitsuzane replied to his brother that his life is nothing but a distraction much to Takatora's surprise. As Mitsuzane went to his room, Takatora receives a call about the two Armored Riders in Helheim Forest.

Attack On Gaim
He appeared as Zangetsu in the forest by throwing a Lockseed, which is eaten by a Elementary Inves. The Inves then transform into Shika Inves. After Shika Inves defeated by Gaim, Takatora attacks him mercilessly, convincing Gaim of the true nature of the Armored Rider battles and mocking him by asking him that his Sengoku Driver was no good to evil.

Revealing his secret
Mitsuzane walks across the hallway and sees Takatora's Sengoku Driver and two other lockseeds. Takatora then calls Mitsuzane for a conversation about his education. Takatora then leaves to take a phone call. Once he finishes he realizes he is in a hurry and goes to work, not knowing that Mitsuzane knows more than he realizes. It's not until when Gaim uses the Suika Lockseed that Takatora realizes that he was missing it. Sid suspects Mitsuzane, but Takatora thinks it is impossible. Later, he goes to a factory to exterminate some Inves. He also sends his troops to burn the the place, due to there is some Helheim Forest's plants were growing in the factory. Unknown to him, Kota and Mitch already saw what they already done and Mitch suspects the white Armored Rider is his brother, due to the Rider's faceplate. Takatora then meets Ryoma to talks about the new model. Though Ryoma said that the new model would be dangerous, Takatora said he would use the new model as he and Yggdrasill Corporation is holding humanity's future.

Attack On Armored Riders
Takatora then receives a message that Armored Riders are entering the Helheim Forest in bulk, which got him mad about Sid giving them all access to Lockvehicles. He then goes to the floor where there is the portal to the Helheim Forest. Takatora then transforms into Zangetsu and gets ready for battle.

Before entering, Ryoma tells Zangetsu not to damage the Sengoku Driver, while fighting the Armored Riders. In the forest, he have fought almost all Armored Riders, even Ryugen without knowing that Ryugen is Mitsuzane. After he manage to defeat the Armored Riders, Zangetsu ordered his troops to sent the defeated Riders back to the real world. While fighting Kurokage, he accidentally damages his Sengoku Driver in a fit of rage and tries to contact his troops. As Takatora returns to the real world, the researchers thought that he fought the Inves in the real world when it was actually Gaim in Suika Arms. Takatora shows his annoyance of the Beat Rider saving his staff and making him look bad, once again comparing the other Riders to trash that were beneath him.

Inves Outbreak Part 2, Testing the Genesis Driver
Takatora tests the Genesis Driver in a simulation and easily defeats the Kurokage troopers. After the testing, Ryoma enters the room and tells him the features of the new belt. He then asks Takatora about the Inves Game, which he reply that he will teach the Beat Riders a lesson and show them reality.

While Takatora and his subordinates are having trouble with the citizens potentially blaming Yggdrasill for a disease outbreak, they are plannihg to close the Beat Rider staging and frame the Beat Riders. Takatora goes to the Charmant to hire Oren, when he realizes that Oren is really useful in actuality to be Yggdrasill's rightful enforcer, such as capturing Gaim and Baron. He is soon fighting an Azure Dragon Inves whom Kouta and Kaito were looking for at the industrial site, and tells them he will deal with them later once he destroys the evolved Inves. Upon getting ready to battle Gaim and Baron, Hase appears and eats the premature Lockseed due to being blinded by a lust for more power, which changed him into an Inves, leaving the three Riders shocked after Zangetsu tries warning Hase to spit the fruit out, but it was too late.

As Ryoji becomes an Inves, Zangetsu started to attack him, but Gaim interferes as he thinks that he is still human. He then tells him that Ryoji is no longer human as the Inves escapes. Gaim chases Ryoji while Baron distracts him. However, Baron is overpowered as Zangetsu orders the Kurokage Troopers to take Kaito away. Later, Takatora went back to his home as Mitsuzane started to ask him about the situation that Zawame is having, but he tells him to focus on his studies instead. In Yggdrasill Corporation, he arranges a meeting with Sid about the Genesis Driver and how they intend to mass produce it until he got a call about Ryoji's rampage in Drupers, which ends their meeting. While Gaim is trying to stop Ryoji and return him to normal, Takatora along with Ryoma, Sid, and Yoko transform into the Energy Riders and Takatora knocks Gaim back with his Sonic Arrow, reverting Kota's transformation. Zangetsu then tells Sigurd to fight the Inves due it being Sid's responsibility for the Inves Games and letting the Armored Riders go into Helheim.

Possible Future
In a possible future, Zangetsu, with Ryugen by his side and his army of Inves and Suika Arms Armored Riders behind him, watched the battle between Gaim and Baron's armies.

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 Kota having no intention to fight him to make his point - that power given by the Lockseeds and Sengoku Driver is no game, letting Kota 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.
