"Treasures are irreplaceable."
―Daiki's boast when stealing a treasure[src]

"It'll only hurt for a moment."
―Diend's warning before using a Final Form Ride Card on a Rider for the first time.[src]

Daiki Kaito (海東 大樹, Kaitō Daiki) is an inter-dimensional thief who travels through the A.R. Worlds as Kamen Rider Diend (仮面ライダーディエンド, Kamen Raidā Diendo, Masked Rider Diend) in order to steal items he deems as treasures belonging to said worlds, while crossing paths with Tsukasa Kadoya on many occasions.

Much like Tsukasa, Daiki would return as a recurring character in Kamen Rider Zi-O with an upgraded Diendriver, traveling to Zi-O's world as he sets his sight on the Ridewatches.



Daiki worked under Fourteen

Daiki Kaito is the brother of Junichi Kaito, hailed from the World of Diend. He was working under Fourteen and he was tasked to capture Glaive, Larc, and Lance. He then discovered that his brother is a Kamen Rider. After Junichi was captured, Fourteen showed Daiki how he brainwashed Junichi to serve under him, in which Daiki was shocked and he left as Fourteen eventually declared Daiki as an outlaw. After he was exiled from his world, he traveled to the World of Decade and he eventually stole the Diendriver from Dai Shocker, becoming his first treasure.

The Mysterious Phantom Thief

"Hey, you. You still haven't eaten... a sea cucumber, Tsukasa?"
―Daiki Kaito’s first line[src]

Daiki's first appearance in the World of Blade.

Daiki briefly appeared in the World of Blade caught in the crossfire in the Kamen Riders' battle against Chalice. He later appears to greet himself to Tsukasa Kadoya and Daiki notes that he found nothing worth taking before making his leave.

Arriving in World of Faiz ahead of Tsukasa, Daiki witnesses Takumi Ogami's battle with the Butterfly Orphnoch as Kamen Rider Faiz and was unable to catch him to acquire his Faiz Gear. When Tsukasa arrives in Faiz's World, Daiki reveals that Faiz is among the student body and warns him not to meddle in his affairs. However, as Tsukasa decides to find Faiz, Daiki gets Lucky Clover's aid by showing them the photograph that Faiz dropped during the fight under the assumption he wanted to join their group. When the Oprhnochs retrieve the Faiz Belt, Daiki reveals his true intentions as he becomes Diend. Diend continues his pursuit for the Faiz Gear until Takumi Ogami found the confidence to become Faiz again during Lucky Clover's attack in Smart Brain High School. Daiki would later find the Orga Gear in the rubble and claims it, before warning Tsukasa to not to meddle in his affairs again as he leaves for the next world.

Diend summons Delta and Drake.

Daiki appeared next in the World of Agito, Daiki is training along with Yusuke Onodera and others to become the next G3-X user. Acquiring the position, it is only revealed later that Daiki's real goal in Agito's World is to steal the newly created G4 chip that was stored in Shoichi Ashikawa's locker, Yusuke confronts him until Tohko Yashiro arrives and blasts the chip to bits. Daiki later aided Yusuke in protecting Ashikawa, only to find out what he possessed to be more precious than the G4 Chip. However, seeing that to be his Kamen Rider Agito powers, Diend leaves the fight scene to the next world as he could not take it with him.

Arriving at the World of Den-O, Kaito attempts to coax the Imagin Momotaros, who took Yusuke's body, into allowing him to use a Final Form Ride card on him to become a DenLiner. When M-Yusuke refuses, he is fought ragged by Diend until he leaves him to reconsider his offer. However, when he offered again, Decade takes the card from Diend while defending Momotaros before helping him regain himself.

Daiki appears in World of Kabuto, interested in the Clock Up ability of the Kamen Riders, Diend saves Decade from TheBee and Gatack, fighting the latter by himself as he is further impressed by the Clock Up System and proceeds to get it from Kabuto. But after the attempt blew up in his face, Daiki receives a "treasure" from Tsukasa which was actually a vial of pepper.

Landing in the World of Hibiki, after an attempt to rob Hibiki, Daiki learns from Asumu of the three scrolls owned by the three Oni schools. Working his way in Zanki's school, he makes a proposition to aid him in settling things with Ibuki and his school. However, during the fight with Decade, Diend reveals his true colors after stealing the Zanki and Ibuki school scrolls and having Momotaros cover his escape. He then admits to getting the last scroll from Hibiki who blocks his path and gives him his Onkaku to give to Asumu along with his final request. The next day, Daiki uses Asumu to distract Hibiki lost enough to steal the scroll, invoking the man's change into Gyuki to cover his escape. However, after reading the scrolls, Daiki returns to give Asumu the Onkaku in order to see the harmony of the three Ongekidō styles. He takes his leave soon after, though thanked by Asumu and the others in spite of his protest that his motives were selfish.

New Worlds, New Treasure

Daiki is seen again in the World of Negatives, following Tsukasa before he overheard Otoya Kurenai speaking of treasure that attracts the thief into fighting alongside Decade against the Dark Riders. Though he gained the treasure, the K-Touch, Diend loses it during the fight after Tsukasa uses the item to become Decade Complete Form


Returning to his homeworld, Daiki reunites with his old friends Haruka Miwa and Shin Magaki as they fight Darkroachi as Kamen Rider Larc and Kamen Rider Lance, the latter blaming him for Junichi's brainwashing. Tsukasa approaches Daiki after Natsumi and Yusuke have also been brainwashed by the evil Fourteen, and Daiki agrees to help Tsukasa, Haruka, and Shin defeat Fourteen and his brother who can transform into Kamen Rider Glaive. Together, they reveal Fourteen's true form as Jashin 14 and destroy him, freeing everyone from brainwashing. However, Junichi revealed he was never under Fourteen's control and was working for him on his own free will. Diend and Glaive fight, though neither has the will to kill the other, especially after Tsukasa tells them that the brothers must look after each other, no matter what.

Junichi and Daiki go their separate ways as Daiki travels to the next world, with the intent to obtain the ShinkengersIcon-crosswiki.png' OrigamiIcon-crosswiki.png. Starting with Genta UmemoriIcon-crosswiki.png's Ika OrigamiIcon-crosswiki.png, Daiki runs off with Genta in pursuit. Deciding to fight him as he cannot lose him, Daiki gets an unexpected visit from Chinomanako who steals his Diendriver and hounds him until he makes his way to Tsukasa who has Yusuke take him back to the Hikari Studio. He eventually gets it back from Shinken Gold when Chinomanako is destroyed by the combination of Decade, Kuuga, and the Shinkengers in exchange for the origami he stole.

In the World of Black RX, Diend's next attempt treasure is the Perfecter from Apollogeist. After Tsukasa had been stranded in the World of Black, Diend comes to his aid and summons Kamen Rider Femme against Kamen Rider Black. When Decade returned to Black RX's world for the final battle, Diend takes his Kamen Rider Black card to summon the Rider to fight alongside Black RX. After claiming the Perfecter, Daiki gave it to Tsukasa who used it to restore Natsumi to life.

Arriving at the World of Amazon, Diend appears again looking for the GaGa Armlet. Diend manages to infiltrate the Dai-Shocker base and learns the armlet is in the possession of Yum Cimil. He joins Decade and Amazon in a fight against the Jyumenki and after GiGi Armlet is stolen from Amazon, Narutaki presents Kaito with a card that will make Diend stronger on the condition that he defeats Decade. Kaito takes the card but says that there are other options as well. Kaito then appears to tell the gang that the boy who stole the GiGi Armlet, Masahiko is being subjected to Dai-Shocker's Human to Monster project. Diend then battles with Decade and Amazon having recovered the GiGi Armlet and manages to steal the GaGa Armlet from Yum Cimil until Decade uses an Attack Ride Card to take it from him. The riders then destroy Yum Cimil and Diend joins the Hikari Photo Studio as a traveling partner into another world. They end up in the worst possible world as they enter the World of the Rider War.

World of the Rider War

In the World of the Rider War, Diend defends Asumu from Kamen Rider Saga and his Fangire minions. Asumu explains to Daiki that there are some treasures that should never be taken. When Tsukasa goes to save Natsumi, Kaito appears to tell him about the trap Super Apollogeist has planned but Tsukasa goes anyway, promising Kaito that if he dies Kaito can have the world. Diend helps Tsukasa fight Super Apollogeist and the revived Kaijin even giving him a Diend Final Attack Ride to destroy Apollogeist. But when the Rider War starts, he shoots Decade at point-blank range marking future battles.

In Decade: Final Chapter, he tries to convince Natsumi to destroy the photographs of Tsukasa as they are only memories of who he used to be as Tsukasa has now accepted his fate as the Destroyer of Worlds as Decade Violent Emotion. After Decade is destroyed, he and Natsumi meet Wataru Kurenai who explains Decade's role as a substitute for the riders of the A.R. Worlds. When Tsukasa is revived, Diend joins the fight against Super Shocker. After the battle, he is seen with the gang posing for a picture.

Crossing Paths With Zi-O

Daiki Kaito in Zi-O

"I won't let you... ...keep all of this world's treasures to yourself, Tsukasa."
―Daiki's message to Tsukasa before setting his sites on what he deems the treasure of the world of Zi-O[src]

Daiki Kaito arrives in the World of Zi-O and like Tsukasa with an all-new transformation device, the NeoDiendriver. He appears somewhere at the top of the building at night, and telling that Tsukasa should've not hogged all the 'treasures' by himself as he sets his sights on Sougo Tokiwa's precious Ridewatches.

Diend summoned Kamen Ride Accel & Birth

The next day, he comes into 9 5 DO to prepare breakfast for Sougo and his friends. After he left, he is exposed immediately upon stealing all of the Ridewatches. Black Woz, who still kept his Miridewatches, triumphs against Diend and reclaimed most of the Ridewatches. Daiki however kept the Zi-O Ridewatch II and GeizRevive Ridewatch and manages to escape to present them to White Woz, with who he has been working. Diend later faces Black Woz again and reclaims the Geiz Ridewatch.

After Geiz transforms, he and Black Woz managed to overpower Diend and he escapes after telling that he’s also a passing-through Kamen Rider and Tsukasa’s friend. He reappears after the fight against Another Blade finished, with White Woz's future tablet in hand, his original target. It appears that he actually works for Ohma Zi-O, and he relays the demon king's message to Sougo and Woz.

The Time-Space Conspiracy

Daiki steals the GrandZi-O Ridewatch from Sougo

After Zi-O has obtained the power of all the previous main Heisei Riders, Swartz tampers with the timeline by contracting with Hiryu Kakogawa to become Another Zi-O II, altering the present to create a reality where he ruled the world with an iron fist. Daiki returns in the altered reality and witnesses Zi-O's defeat at the hands of Another Zi-O II, marking the latter as his next target. While he enters Another Zi-O's palace to steal his Zi-O II Anotherwatch, he is stopped by Swartz. However, Swartz decides to bestow him with the ability to freeze time. Daiki was later recruited to steal the GrandZi-O Ridewatch from Sougo using his new powers.

Decade fights Diend in the forest

Back at Hiryu's castle, Tsukuyomi is brought before Swartz as he reveals the fact that they are siblings, and takes away both her and Ora's time powers. Before he can do the same to Heure, he is able to get away with Ora. Swartz orders Daiki to kill the both of them, which he complies. Daiki finds the disgraced Time Jackers in a house, just as some Another Riders are looking for them. He says he does not want to fight and gives Ora the GrandZi-O Ridewatch that he has stolen earlier. However, on his way out, he signals their location to two Another Riders nearby, just to live up to Swartz's expectations. Later, as Zi-O, Geiz, Woz and Decade unite to overthrow Hiryu, Diend appears and shoots Decade from behind, saying that he is happy to see him again. The two enter battle, but just when Decade had the upper hand, Diend freezes time. This allowed Swartz to steal Kamen Rider Decade's power away from Tsukasa, creating the Decade Anotherwatch. GrandZi-O eventually managed to defeat Another Zi-O II and returned the world to normal, but Daiki takes the Zi-O II Anotherwatch from Hiryu as his treasure, which Swartz allows him to do. He then leaves to parts unknown.

"Hey, you just died, Tsukasa. By the way, have you eaten a sea cucumber yet?"
―Daiki after reviving Tsukasa[src]

Daiki activates the Zi-O II Anotherwatch to save Tsukasa's life

When Tsukasa, Sougo, and Tsukuyomi visit the year 2058 in order to investigate Tsukuyomi's past, Tsukasa is hit by Swartz's attack meant for Tsukuyomi, which leads to his death. Daiki appears through an Aurora Curtain and realizes Tsukasa's condition. Daiki uses the Zi-O II Anotherwatch to reverse time and revive Tsukasa. Although Tsukasa came back to life, the Anotherwatch consumed Daiki into becoming Another Zi-O II. Sougo returns the Decade Ridewatch to him, revealed to have contained half of his powers, and allows Tsukasa to become Kamen Rider Decade once more. After pushing Another Zi-O II back into the present, Decade transforms into Kamen Rider Zi-O and fights alongside GrandZi-O to defeat Another Zi-O II, freeing Daiki was free from the Anotherwatch's influence.

As more monsters started to surface and the city became in utter chaos, Tsukasa declares that Zi-O's world must be destroyed. Daiki and Tsukasa help Sougo, Geiz, Woz to combat the monsters. During Decade's fight with Another Decade, Diend manages to freeze Another Decade while claiming that he still has the Time Jackers' power. After unfreezing Tsukasa, Daiki states that they're now even and proceed to battle Another Decade together.

Daiki and Tsukasa during the world rewritten event.

"You are having fun, Tsukasa? We are together witnessing the end of the world. Don't you think that is the ultimate treasure?"
―Daiki's words before aiding in the final battle[src]

Diend appears to aid Decade, Geiz and Woz while hordes and hordes of monsters spawn endlessly. In the middle of the chaos, Tsukuyomi shows up and stops time, freezing everyone in place for Swartz, as Another Decade, to fire an energy blast at them. Before he can fire another one, Sougo appears and interrupt the attack, saving them. Eventually, with the power of Ohma Zi-O, Sougo is able to defeat and destroy Another Decade once and for all. However, after the battle, Sougo decides to reset the timeline. Daiki and Tsukasa watch as the history of the world is being rewritten.

Kamen Rider Zi-O NEXT TIME: Geiz, Majesty

White Woz stealing Daiki's powers

Daiki encounters and fights White Woz while looking for Geiz in the present. However, Woz defeats him as Futurering Shinobi and steals his powers, creating the Diend Anotherwatch. After this, Daiki escapes into 2018 in order to return Keito Myokoin's memories as Geiz, and later uses the seized Future Note from the main series to restore Sougo and Alpina's Rider powers.

Daiki during the birth of GeizMajesty

After Another Diend defeats Geiz in GeizRevive, Daiki offers his ninteen Secondary Rider Cards, which immediately combine into the GeizMajesty Ridewatch, enabling the swift takedown of White Woz. Another Diend is defeated and Daiki is able to transform into Diend once more.

Novel Appearances

Kamen Rider Decade: The World of Tsukasa Kadoya ~The Garden Inside the Lens~

Main article: Daiki Kaito/Novel


Daiki is a mysterious young man who is portrayed as being cheerful to the extent of being annoying to those around him, but becomes serious in battle and sees material objects as more important than anything else. Narutaki, aware that Daiki is Diend, avoids getting in his way. He also appears to know about Tsukasa's past, referring to sea cucumbers as being something Tsukasa had always wanted to taste. He travels from A.R. World to A.R. World, stealing what he refers to as "treasures".

It is revealed that he comes from an A.R. World (referred to as the "World of Diend") where he was an officer who served the evil Fourteen who has deemed Kamen Riders as threats to the public peace. Daiki hunted them down and turned them in for education until he captured the leader of the Kamen Riders: Kamen Rider Glaive. When Glaive is unmasked, he is revealed to be Daiki's older brother Junichi. By then, Daiki learns the truth that Fourteen brainwashes people, powerless to stop him. Losing his self-confidence and seeking to undo all of the mistakes he had caused, Daiki stole the Diendriver from Dai-Shocker, becoming Kamen Rider Diend and becomes Fourteen's new most wanted Kamen Rider.

Daiki leaves his world, traveling to other worlds and taking their treasures as a means of self-delusion until he crosses paths with Kamen Rider Decade. He considers the Hikari Studio residents as his friends, even calling Decade a "comrade" and helping him in battles selflessly. However, like how Decade began doing after regaining his past memories, Daiki is not beyond abandoning them, though only while hunting his treasures. He also seems to be willing to steal from the weak and innocent, as he stole from Kurosaki when he was a child. This makes him one of the more questionable heroic Secondary Riders when it comes to morality.

Powers and Abilities


  • Dimensional Travel: Like Tsukasa, Daiki can travel within worlds via Dimensional walls.
  • Temporal Freezing: Bestowed by Swartz against his will, Daiki possesses the Time Jackers' ability to freeze time. The first instance he tried out this power was to steal the GrandZi-O Ridewatch from Sougo Tokiwa. For some odd reasons, he was able to freeze Swartz when he saved Tsukasa from being attacked by Swartz.
  • Ridewatch Creation: After losing his Rider powers to White Woz, Daiki's Rider Cards eventually combined into the GeizMajesty Ridewatch through unknown means.
  • Temporal Protection: Being an otherworldly human like Tsukasa, Daiki is immune to the timeline changes brought about by Sougo's adventures and powers.

Former Powers

  • Time Reversal: Via the use of the Zi-O II Anotherwatch, Daiki could reverse time on a subject. This ability was lost when the Anotherwatch was destroyed by Tsukasa and Zi-O to save his life.


  • Expert Thief: Daiki is a treasure hunter who travels the A.R. Worlds in search of treasures and can sometimes able to pickpocket from out of sight, even a past version of himself was able to steal the Kurosaki family's pistol heirloom from Daiki.
  • Expert Marksman: To be added


He mostly appeared as Kamen Rider Diend. Only in Episode 12 of Kamen Rider Decade, he briefly wore the G3-X suit.

Kamen Rider Diend's ending theme is entitled "Treasure Sniper".

Behind the Scenes


Daiki Kaito is portrayed by Kimito Totani (戸谷 公人, Totani Kimito), who reprised his role in Kamen Rider × Super Sentai: Super Hero Taisen and Kamen Rider Zi-O, in Episode Yellow when Daiki disguised himself as Naomi, he is portrayed by Rina Akiyama (秋山 莉奈, Akiyama Rina). In Super Hero taisen Otsu, when Daiki disguised himself as Master of Fumen, he is portrayed by Hiroshi Doki (道木 広志, Dōki Hiroshi).

As Kamen Rider Diend, his suit actor in Kamen Rider Decade was Eitoku (永徳), who has been the suit actor for the Secondary Riders of the Heisei Phase 2 Series from Accel to Meteor, as well as Baron. In Super Hero Taisen, his suit actor was Ryo Yokota (横田 遼, Yokota Ryō).

Concept Art

Another Zi-O II was designed by Yutaka Izubuchi (出渕 裕, Izubuchi Yutaka).


  • Kamen Rider Diend name comes from the English words "die" and "end", as well as "the end".[12]
  • Daiki's surname is a homophone of the Japanese word kaitō (怪盗 phantom thief), a role he fulfills in Decade.
  • In some materials in Decade, Daiki's surname is spelled in English as "Kaitou" rather than "Kaito"; this is considered an acceptable alternative Romanization for the long "O" sound.
  • Unlike Kamen Rider Decade, Daiki can't change into any of the past Riders in the same way he could. The only times he became a different Rider was when he briefly wears the G3-X armor and in Zi-O, where he became Another Zi-O II.
  • Exactly how and when Kaito stole the Diendriver from Dai-Shocker was never clearly stated, but many fans believe that when he ran away from his world, he stole the Driver while traveling and stealing treasure.
  • It is possible that when Diend summons a Rider, he is actually controlling their mind (or perhaps corrupting them instead) as some of them did act out of character when they fought his enemies.
  • He is the second Rider after Daisuke Kazama to use a gun to transform into a Rider.
  • Despite having an updated transformation device, there is no changes for Diend's suit when using the NeoDiendriver unlike Decade sporting the Neodecadriver.
  • Kaito made his first appearance in Kamen Rider Decade in the World of Blade. He then made his first full appearance in Kamen Rider Zi-O in the Kamen Rider Blade episode of that series. It also should be noted that his homeworld is heavily inspired by the summer movie, Kamen Rider Blade: Missing Ace.
  • Kaito is currently the only Secondary Rider to be a recurring character in Kamen Rider Zi-O.
  • As with every Another Rider, Daiki as Another Zi-O is the opposite to Sougo Tokiwa. While Sougo earns the powers from the Kamen Riders fairly with approval, Daiki and Another Riders have the properties of stealing Rider powers.
