His Rider Form, Decade Form has appearances like magenta, white, and black colored Rider Armor with green visor and yellow signal pointer, he also use **Neo Decadriver** for his Driver Belt, which has a magenta color same with his base armor color and also he bring stuff in his right belt called **Ride Booker**, and he use this Ride Booker to store his cards and he can use his Ride Booker to be a weapon in Sword Mode and Gun Mode.

Tsukasa is an interesting individual to say the least. Initially, one would get the impression that he’s an irritating, hypocritical, cavalier, and a bit self-righteous, and well, that’d be correct, to a point. He tends to press forward regardless of the situation, most cases seeming to have a certain *"I'm better than you"* attitude about it all. He seems cold when it comes to others, and like someone that would be terribly ignorant about things (despite the fact that he’s very talented when it comes to everything). Of course, this is pretty much just the impression anyone gets from watching him for a little while. He’s uncaring, rude, and mostly kind of a bad person.

All in all, he’s not a terrible person. He’s just bad with other people. He wants to find a home and somewhere he belongs and that’s really all his grand aspirations end up being. He also really likes photography but, the photos that he takes always having bad results.

Usually, before he transforms into Decade and fight his opponent, Tsukasa would say *"Tōrisugari no Kamen Raidā da, oboeteoke!"* (I'm just a passing-through Kamen Rider. Remember that!).

#### Rider Time: Kamen Rider Decade VS Zi-O - Decade Mansion's Death Game

Later, he's finally back in **Rider Time: Kamen Rider Decade VS Zi-O - Decade Mansion's Death Game** and **Rider Time: Kamen Rider Zi-O VS Decade - 7 of Zi-O!**, were in the Rider Time: Kamen Rider Decade VS Zi-O - Decade Mansion's Death Game, In the series, Sougo, Swartz, Heure, Ora, and a couple of others became trapped in a mansion on a desolated island. A masked man orchestrates a "King Game", saying that whoever wins the game will become king of the world. Anyone who fails a task in the game will be killed by **Another Ryuki**. When Yusuke Onodera, Misa Kudo, and Swartz observe a deceased old man who has been killed by a mysterious person while holding a lot of cash, Tsukasa appears and greets Yusuke after not seeing each other for a long time. At first, the remaining people in the mansion are suspicious because of Tsukasa and Yusuke's acquaintance. Tsukasa explains to his old friend that the mansion they are in is the entrance to a dimensional gap and that the **"King Game"** has happened many times in the past. He also reveals that the true mastermind of the King Game is the "True Sougo", a man destined to become Ohma Zi-O, who has also become weakened because of having used "too much power". He further notes that nobody is to be trusted in the mansion, since it is connected to various worlds, and no one can know who is from what dimension. The next day, the masked man appears on TV and continues the game, with Tsukasa as a participant. This time, the challenge is some simple games of rock-paper-scissors. However, if 5 games end in a draw, everyone will die. Misa Kudo decides to be the loser voluntarily, saying that she has a plan. Another Ryuki promptly appears and kills her for being the loser. Swartz mocks Misa for being too weak, only to be shoved food in the mouth by Tsukasa. While eating, he proclaims he cannot lose, to draw the "true Sougo" out. The Game continues. This time, it is a hide-and-seek challenge where anyone first found by Another Ryuki will lose. Swartz is killed by an unknown person while playing, alerting Tsukasa. Before dying, Swartz tells him he wants a poisoned dumpling. The masked man reveals his final challenge: The rest of the mansion must each find a treasure weapon in the compound and use them to kill one another until there is only one left, and Another Ryuki will be killing them at random also. Tsukasa manages to find a sword. He walks outside and finds Yusuke, but the latter does not want to open his box of treasure and gives Tsukasa instead. Distracted, Tsukasa is sneak-attacked by Yusuke, who reveals himself to be the mysterious killer all along. He notes that Yusuke is not the same Yusuke Onodera he knows and quickly deducts that he is from an alternate dimension. Soon after, just as Yusuke thinks he has won, Sougo shows up, having survived the attempt on his life thanks to his robot physiology. At this point, Tsukasa learns that nearly every player in the King Game is not the same person that as he knows: Sougo Tokiwa is a robot from a timeline where humanity has been destroyed and replaced by machines, Heure is a space ninja, and Misa is a ghost. The robot Sougo then helps Tsukasa back to the mansion. Inside, the masked man finally makes his presence and identity known: He is none other than Decade's old enemy, Narutaki. He explains that the "True Sougo" has become very weak somehow, and he creates this Game to find a suitable body, with Narutaki acting as the referee. Just then, Ohma Zi-O appears inside a mirror, attempting to take Yusuke as the body, but Yusuke proves to be unsuitable as a host and disintegrates. At this point, Narutaki confesses that he has become tired of his role as the referee, and has guided Tsukasa to the mansion so that the Game could be stopped. Tsukasa and Sougo transform and jump into the mirror to battle Ohma Zi-O. In the wasteland, the two are joined by Kamen Riders Diend, Kiva-la, and Kuuga. Despite outnumbering the tyrant, they quickly find themselves on the losing side. Zi-O, seeing no other choice, gives Decade the Saber Ridewatch, telling him to deliver it to someone who can use its power. Decade and the four other Riders are then defeated by Ohma Zi-O in a massive explosion.

And for Rider Time: Kamen Rider Zi-O VS Decade - 7 of Zi-O!, After having survived the battle with Ohma Zi-O, Decade is still hellbent on ending his reign. Due to a distortion within several different timelines focused around their versions of Sougo Tokiwa, Tsukasa returns to destroy the resulting world by killing all of the alternate Sougos within, while trying to prevent Ohma Zi-O from rising to power as well. Driving a jeep towards Hikarigamori Academy, he spots a frightened, cowardly Sougo trying to run from him, Tsukasa stops the jeep to transform into Decade, and instantly kills this Sougo with a Final Attack Ride. Tsukasa eventually arrives at Hikarigamori, but turns around when the actions of Sougo C lead to a fight and lure out several more alternate Sougos. The night afterward, it is revealed that Tsukasa is slowly starting to disappear, showing that his wound during the stab from the evil Yusuke and Ohma Zi-O actually endangering his life because Tsukasa has yet to be treated into full condition. After the other alternate Sougos are erased through a mix of infighting and Tsukasa's own actions, the mysterious child Tsukuyomi has been helping appears and reveals himself as yet another alternate version of Sougo (The "True Sougo" that Tsukasa has been hunting) who has now become Ohma Zi-O. Tsukasa attempts to intervene by equipping the **K-Touch 21** and transforming into **Decade Complete Form 21**, but his weakened condition proves fatal, with Ohma Zi-O easily defeating Tsukasa once more. Once Sougo A manages to remanifest, he finds Tsukasa near the pond where Ohma Zi-O has defeated him earlier, and is given the Saber Ridewatch. Following Ohma Zi-O's destruction at the hands of **Zi-O DecadeArmor Saber Form**, Tsukasa begins to disintegrate, relieved that his journey will finally be over before quietly passing away and restoring all seven timelines to their original state.
