Tsukuyomi (ツクヨミ) is an amnesiac 18-year-old young woman[1] who initially had no memory of her past before discovering her true heritage as a princess named Alpina (アルピナ, Arupina). Stranded in a different timeline with her memories erased by her older brother Swartz, she joins the Resistance and unknowingly acquires a Ridewatch that would allow her to become Kamen Rider Tsukuyomi (仮面ライダーツクヨミ, Kamen Raidā Tsukuyomi). In an effort to change her apocalyptic future, she travels to 2018 with Black Woz and Geiz Myokoin in an attempt to guide Sougo Tokiwa away from his fate as Ohma Zi-O.

After Sougo rewrote the timeline, Tsukuyomi was revived and is currently living in 2018 with the name Alpina Tsukuyomi (月読 有日菜, Tsukuyomi Arupina)[2]

History

Background

Alpina is a resident from an alternate timeline where she and her older brother Swartz were members of a royal family with temporal abilities. However, after Alpina was chosen to succeed the throne over her brother, Swartz erased had her memories and left her stranded in Ohma Zi-O's timeline, where she was found by the Resistance and given the code name "Tsukuyomi", which she kept for the next ten years.

During one of the Resistance's battles, she encounters the past version of Sougo Tokiwa, who slips a blank Ridewatch into Tsukuyomi's pocket. After Ohma Zi-O wipes out a number of Resistance members, Tsukuyomi was saved after her captain pushed her to a trench. As Geiz Myokoin became motivated to travel to the past to kill Ohma Zi-O in 2018, Tsukuyomi who follows him to observe Sougo Tokiwa's actions.

Traveling to the Past

Using her Time Mazine, Tsukuyomi rescues Sougo Tokiwa of 2018 from Geiz and hid across different time periods. She revealed to him that in the distant future, Sougo will become the most evil and despised demon king in all of history. Despite her attempts, she is unable to prevent Sougo's transformation into Kamen Rider Zi-O and is hesitant to trust him. But after observing more his actions, Tsukuyomi doesn't believe he really could become Ohma Zi-O, much to the disagreement of Geiz who is more confrontational towards Sougo.

Despite not wanting to harm the Sougo of the past for his future actions, Geiz and Tsukuyomi learnt the Time Jackers have arrived in the era and aiming to replace Ohma Zi-O using the Another Riders. The pair questioned how the good-natured Sougo Tokiwa became the villainous Ohma Zi-O, opting to observe him by moving in Sougo's residence and disguising themselves as students in his school. Although Sougo tried to get into his good graces, Tsukuyomi easily gotten along with him compared to Geiz. Tsukuyomi would assist the both of them to combat the Another Riders, while uncovering each host's motivations and modus operandi.

One day as the Dai Mazines have arisen at the city, Ohma Zi-O's servant Kasshine arrives from the future to kill Tsukuyomi and Geiz to "protect" Sougo. Following Tsukasa Kadoya's intervention, Tsukuyomi accompanied Sougo as he is brought to the year 2068 to meet Ohma Zi-O. Their meeting had traumatized Sougo to the point of having his Ziku-Driver destroyed when they returned to the present. Despite completing their mission, Tsukuyomi and Geiz decided to stay and they motivate a forlorn Sougo to pursue being the "greatest and kindest Demon King". However, the decision for Sougo to temporarily give up the Ziku-Driver began to diverge the timeline to new outcomes.

The Demon King Conspiracy

After the new year had begun, the group uncovers that the Time Jackers are creating Another Riders based on the future Kamen Riders that have yet to exist. Upon the arrival of a second Woz, referred to as White Woz, the group would discover that the timeline has diverged to a potential timeline where Geiz defeats Ohma Zi-O and became a "savior". Meanwhile, White Woz to recover the powers of the Future Riders as Kamen Rider Woz.

While on the pursuit against the elusive Another Another Ryuga, Geiz was accidentally killed in an attempt to attack their adversary. This moment was reversed when Sougo had evolved into Kamen Rider Zi-O II, granting him the power to rewind time. However, this new evolution became concerning to Tsukuyomi as what Sougo has acquired is similar to that of Ohma Zi-O. Becoming more and more afraid of Sougo, Tsukuyomi turns on him and allies herself with White Woz as she expressed fear that Sougo will become Ohma Zi-O.

During the emergence of Another Zi-O, Tsukuyomi began investigating Sougo's past after discovering a link between him and Hiryu Kakogawa. She attended a bus in 2009 as a passenger and discovers Swartz sabotaging the bus. As she tries to stop him, Swartz teleports away with the children. Tsukuyomi managed to escape thanks to Tsukasa Kadoya before the bus exploded and killed all the adults. Geiz, having witnessed the bus crashing, misinterpreted the events as Tsukuyomi killing a young Sougo, causing him resolved to become GeizRevive. Having witnessing the young Sougo's trial as he survives an alternate timeline of a city under attack. Tsukuyomi rushes back to 2018 where she reunites with Sougo and Geiz.

Tsukuyomi managed to find peace with Sougo and understood the conspiracy behind his kingship. With Oma's Day was vast approaching, Sougo brings Geiz and Woz together as they strived to create a new future together. This allows Zi-O merges with Geiz and Woz to become Kamen Rider Zi-OTrinity and were able to save the world. Although Sougo had not become the demonic tyrant on the event, they have so far yet to avert Ohma Zi-O's rule.

Rediscovering Her Past

Tsukuyomi continued to assist Sougo after being tasked to collected the six Ridewatches, as it could help him defeat Ohma Zi-O. The group embarks to meet with the previous Kamen Riders to prove themselves worthy in inheriting their powers. In the process, the Time Jackers have begun creating Another Riders in the present in an attempt to prevent Zi-O from growing stronger.

The group would additionally become aware of Tsukuyomi's sudden temporal abilities and how she had no memories of her childhood past. After meeting with Tsukasa Kadoya, who notices time and space is being distorted following Kamen Rider Ginga's presence, Tsukuyomi ventured to the year 2058 with Tsukasa and encounters her younger self with her older brother. Although Tsukuyomi and Tsukasa were forced back to 2019 by Swartz, he discreetly remarks how far his sister's powers are growing, confirming that they are siblings.

Eventually, Sougo managed to complete the collection of twenty Heisei Ridewatches, resulting in the birth of Kamen Rider GrandZi-O, having obtained the power to finally prevail in building a new future together.

The Royal Connection

Swartz reveals him to Tsukuyomi as her older brother

Sometime after Sougo acquired the power of GrandZi-O, the timeline became altered by the appearance of Another Zi-O II, causing Tsukuyomi and Geiz had lost every memory of their time with Sougo. While Sougo manages to get through to the pair, Swartz has Tsukuyomi captured where he finally reveals they are siblings. Tsukuyomi learns of her heritage to manipulate time and how her powers exceeded Swartz. While Swartz tried to take her powers away, an undercover Woz rescues her. Following Another Zi-O II's defeat, the world was returned to normal and restored Geiz and Tsukuyomi's memories in the process, while imparted with her relation with Swartz.

Tsukuyomi still had lost a majority of her powers from Swartz as he absorbed nearly all of it. One day, Geiz and Tsukuyomi are visited by Kamen Rider Aqua, Michal Minato, who arrived from the future to take both of them home. She learned from Michal that her real name is "Alpina" and their efforts will be fruitless because Sougo will become Ohma Zi-O because of them. As Swartz made his presence known as Another Decade, he displayed his ability to summon Dark Riders from different timelines, only to be stopped by the Kamen Riders for the time being.

As Swartz grew stronger as Another Decade, elements related to the previous Heisei Riders began to surface, and monsters began spawning all over the city. She accompanied Sougo in uncovering Swartz's true agenda to gather the twenty Kamen Riders' powers from each dimension and create a new world. Tsukuyomi participates in to Tsukasa's plan to destroy his world but save the people in it. As part of their plan, Tsukuyomi would be made into a Kamen Rider to link Sougo and Tsukuyomi's worlds to transfer the residents to her world. However, in a surprise turn of events, she would seemingly betray the heroes for Swartz's servitude.

Death

Tsukuyomi bowed down to her older brother Swartz, serving under him as her king. While the Kamen Riders tried to defend the city from the monsters, she warned that the world's destruction is imminent. After Geiz's death and Sougo transformation into Ohma Zi-O, Tsukuyomi landed a blow on Another Decade from behind, revealing he plan to attack her brother while distracted. However, Swartz retaliated by obliterating Kamen Rider Tsukuyomi, angering Ohma Zi-O to vanquish Another Decade. As Tsukuyomi expressed good wishes to Sougo, her spirit faded away in peace. Afterwards, Sougo accesses his powers to rewrite the world's history to ensure he'll become king with his friends. Tsukuyomi's timeline is erased as the world and reintergrated with Sougo's timeline.

New Timeline

Alpina Tsukuyomi

In the new timeline, Tsukuyomi, Geiz, Heure, and Ora were restored as ordinary people attending Hikarigamori High School in September 2018 with Sougo.

Personality

Tsukuyomi is a no-nonsense individual and shares relatively the same goals as Geiz, though she is prone to stopping Sougo from becoming Ohma Zi-O by not having him transform, as opposed to Geiz's idea of outright killing him. Her conviction to her ideals is great enough that she would save Sougo from Geiz when the latter attempts to kill him. After hearing Sougo's conviction of wanting to become a good king, Tsukuyomi began to trust him as she found almost no evidence that Sougo would eventually become Ohma Zi-O. However that conviction faltered slightly when Sougo acquired Zi-O II, which caused Tsukuyomi to become paranoid and begin to believe that Sougo could in fact become Ohma Zi-O. She sides with White Woz in an attempt to stop him, though she eventually defended young Sougo in 2009 from Swartz and realized the future could indeed be changed.

When Tsukuyomi discovers her temporal abilities, she became shocked and horrified over this fact, but was later able to accept for who she was now, rather than who she was before.

She is also shown to appreciate different kinds of foods, such as Shouichi's cooking and sweets, although according to Geiz, she has a preference for really spicy items.

Powers

Tsukuyomi temporarily stopping time.

  • Temporal Freezing: As a member of the same royal family as Swartz's, Tsukuyomi shares the Time Jackers' ability to freeze time. Her ability is powerful enough to even freeze Swartz himself, something that both Heure and Ora cannot do as they have weaker versions given to them by the former. After learning to accept herself for what she was, she is able to control her ability at will, having used it to save innocent civilians from being crushed by falling debris and allowing allies to move within the confines of her time freezing. This ability may or may not be inherited. In the altered timeline, Tsukuyomi is fully aware of her powers and is able to use it to the best of its ability, though it can be easily canceled out by other Time Jackers.
  • Power Absorption: Much like Swartz, Tsukuyomi can absorb time manipulation powers from any person who possesses them. She used this to try and drain all of Swartz's powers but failed, only managing to retrieve a small fraction of her powers.
  • Energy Blade: Tsukuyomi could manifest a white energy blade from her hand for offensive purposes. She first manifests this blade when she stabs Swartz at his back before she is, in turn, killed by her brother.
  • Energy Redirect: In Kamen Rider: Reiwa The First Generation, Kamen Rider Tsukuyomi catches blasts from the Battle Magia with her hands and fires them back with her own energy.

Kamen Rider Tsukuyomi

Like Zi-O and Geiz before her, Tsukuyomi transforms by inserting the Tsukuyomi Ridewatch into the right-hand side of the Ziku-Driver and spinning the Driver 360 degrees.

Tsukuyomi's ending theme is entitled "Tsuki no Michiru Toki".

Vehicles

Relationships

Friends

  • Sougo Tokiwa/Kamen Rider Zi-O: Like Geiz, Tsukuyomi believes Sougo to be the evil tyrant Ohma Zi-O and decided to go back in time to change his fate. At first, she seemed confused that a light-hearted teenager like Sougo could grow into an evil Demon King. But that quickly changes when she notices his earnest motivation to become a king and his ability to activate the Zi-O Ridewatch. Despite this, she wants to help and guide Sougo in being a hero as Zi-O so time and history can hopefully be altered for the better. But she then loses her faith in him when he becomes Zi-O II. She then reaffirms her mission to kill Sougo, even going as far as time traveling to 2009, seemingly to kill Sougo when he was still a child, while she actually protected the younger Sougo from Swartz after she learned the truth. Once discovering that Swartz was responsible for what had occurred and the possibility of Sougo's future as Ohma Zi-O could be altered, her doubt was cast aside as both she and Geiz reconciled with him and return to 9 5 DO. When Swartz unveils his master plan in becoming the king himself, Sougo goes forward into the future to give Past Tsukuyomi a Ridewatch, so that she'll be able to fight her brother as a rider, until it backfired on them. It turned out to be a deception as she strikes Swartz but ends up killed as Sougo avenges her & Geiz as Ohma Zi-O. In the end, after Sougo remakes the timeline anew, she and Geiz are reborn as high school students in Sougo's new present time.
  • Geiz Myokoin/Kamen Rider Geiz: Geiz and Tsukuyomi were on the side determined to defeat Ohma Zi-O in the year 2068. But after witnessing many casualties, Geiz came to the conclusion that he needs to kill the man who would become Ohma Zi-O in the past. Tsukuyomi does not agree with this but Geiz goes back in time. She tries to protect Sougo from him, believing it's not right to kill him for something he hasn't even done yet. After Geiz tries to help Zi-O, she asks him to do what he come for. Although Tsukuyomi remains allies with Geiz, she decides to settle their mission on her own. Upon learning the whole truth, Tsukuyomi later convinces Geiz to stop his and Sougo’s duel to the death. In the final battle against Swartz & his master plan in becoming king using Ohma Zi-O's powers & Tsukuyomi's time abilities, she betrays Geiz & the others as a means of luring Swartz into her trap of ending him until her death. In the new timeline, Geiz & Tsukuyomi are now high school students in Sougo's time & no longer from the future.

Woz watches over Tsukuyomi & the others in the new present.
  • Swartz: Swartz is in fact her older brother, though their relationship seems to have gone estranged since Tsukuyomi lost her memories and the way Swartz has been treating her since. However their interactions increased once Tsukuyomi's time-stopping abilities were re-awakened in her teen years. Once the world starts showing signs of being destroyed, Tsukuyomi travels back in time with Sougo with the intention of killing a younger Swartz but could not bring herself to kill her brother. However, in the new timeline, he became principal of Hikarigamori High School.
  • Ora: Once they were in enemies in the old timeline, now high school friends & students in the new present.

    • Tsukasa Kadoya/Kamen Rider Decade: Tsukuyomi was saved by Tsukasa during the bus accident in 2009. They both learn the whole truth about Sougo’s past and Tsukasa himself explained his motives to Tsukuyomi. Thanks to the knowledge, Tsukuyomi regained her faith in Sougo. He also helped her discover her past.
    • Shoichi Tsugami/Kamen Rider Agito: Tsukuyomi met Shouichi while she isolated herself from her fellow 9 5 DO members due to her newfound ability to freeze time and her unknown past due to her amnesia, something Shouichi could relate to.
