==History==
===Background===
Ikki Igarashi was born sometime in 1999 as the first-born son of Genta and Yukimi Igarashi, and also the elder brother to Daiji and Sakura. When he was four,Character Album 2022 , p. 12. Ikki bore witness to Happy Spa being burnt down by his father, who had been possessed by Vail. Fearing for the safety of family, he manifested an inner demon who erased his traumatic memories of the event to protect him and stayed dormant for the next eighteen years. The bathhouse would be rebuilt then, and his family continued to live out a normal life. At one point during his childhood, Daiji went missing during a camping trip and Ikki was able to find him.
He started playing soccer in elementary school and has since won multiple MVP awards. Ikki attended Ritsu Daini Chuo Middle School, then later Kitase High School where he joined the soccer club and befriended Koji Ikeda while being coached by Subaru Kimura. In their efforts, they won the Japan High School Soccer Tournament in 2017. Although Ikki and Koji aspired to go professional, he accidentally injured Koji during one practice. Because of the guilt, Ikki fell under too much pressure and gave up soccer after graduating high school. Since then, he began helping his family run the bathhouse. Ikki's file according to Fenix
===Becoming Kamen Rider Revi===
One day, while helping out his customers, Ikki became aware of his inner demon Vice. He tried to make the best of his situation, but often ran into trouble because of his demon's antics. While attending Daiji's appointment ceremony at Fenix, the event is sabotaged by the Deadmans. Learning the Revice Driver is the only system capable to combat them, Ikki picked up the Driver and was able to transform due to his connection with Vice. He was christened by the belt's creator, George Karizaki, as "Kamen Rider Revi" but lacked a desire to be one due to his personal priority being the family bathhouse. 
Although Daiji tried to persuade him to join Fenix, Ikki opted to use the Revice Driver occasionally to fight Deadmans. Frustrated by Vice's mischief and hunger for humans, Ikki had refused to even use the Revice Driver unless the demon agreed to stop harming people. After the two came to an agreement and resolved an incident regarding his childhood friend Ayaka Oketani, who was driven to become a Deadman, Ikki came around and signed the contract with Fenix to become a full-time Kamen Rider, allowing Fenix to provide additional financial support for his family. He became assigned to perform "hero work" to help civilians in Deadman related incidents.
===Kamen Rider Revice: The Movie===
Kamen Rider Revi and Kamen Rider Vice would appear to fight off the Giff Juniors led by Orteca who were terrorizing a theme park. While the pair later retired the day off in the bathhouse, Daiji would inform them of a new Deadmans attack elsewhere in the city. Arriving to battle the Spider Deadman, Revice would assume the Megalodon Genome to vanquish the monster together. After their victory, Revi let Vice roam free to soak himself in the bath.
===Time of the Igarashi Siblings===
As the duo continued to combat against stronger Deadmen, they faced Daiji's inner demon Kagero who fought Daiji for control over their body. Hiromi Kadota began assisting the duo as Kamen Rider Demons until Ikki was able to help Daiji regain control of his body as Kamen Rider Live. However, Ikki was unaware that Sakura began feeling inferior and wanted to help her brothers fight. Ikki reminded her that being weak was okay as Sakura unlocked her fullest potential as Kamen Rider Jeanne.
With Ikki and Vice's bond growing stronger, George began to prepare a new upgrade for Revice. While still hesitant to fully come to accept Vice as a buddy, Ikki decided to turn him corporeal when the Fenix Skybase was under attack by the Deadmans. This allowed the Rex Vistamp to completely synchronize with the Barid Rex Vistamp. Having placed his utmost faith towards his demon, this allowed Ikki to evolve into Revi Barid Rex, granting him access to all previous Genomes and Remixes the duo have utilized up until that point. 
===Kamen Rider: Beyond Generations===
Ikki and Vice continued their contract work with Fenix while tending to the bathhouse during his free time. After reuniting with the members of the Sword of Logos whom he encountered a few months prior, they joined forces to fight the demon Diablo, who emerged to threaten the Earth's future. They would also encounter time-displaced Shocker scientist Ryunosuke Momose, who sought to make amends with Hideo, his young son he left behind in 1971, who is now an adult man in 2021.
While his siblings and Vice go to the future, Ikki stayed behind in the present to help defeat Diablo, fighting on his own until everyone was able to return. He and Vice would join forces Xross Saber and the benevolent Century to battle a giant Diablo. Revice would also access the Neo Batta Genome to vanquish Diablo for good.
===Dismantling the Deadmans' Operations===
One day while cleaning the bathhouse, Ikki was forced to battle Yasushi Kudo after he had escaped Fenix's custody. While Ikki admitted he liked to intrude himself to fix others' problems, Kudo called him out for acting without considering the consequences. Although his words made Ikki become unsettled, Vice encouraged him to recognize the responsibilities that he would carry. Ikki carried on with Vice's words and helped Fenix shut down the Deadmans' operations.
===Kamen Rider Revice: The Mystery===
After fighting the Orangutan Deadman, Ikki and Hiromi followed its trail to Pension Nijitenka where they met its staff, the proprietor Suzu Saionji and the caretaker Shinzo Hanawa. While trying to search for the Vistamp holder among its lodgers, Ikki is strung along for a murder mystery when one of the suspects ends up dead. Working with Genpachiro Otta, he investigated the lodge and learned that one of the suspects was Naoya Kaido. Deducing that Naoya was actually a victim, Ikki pointed out that the true culprit was Suzu, who had planned to kill Ikki as revenge against George Karizaki. Joining forces with Ryu Terui, Ikki and Vice prevail against Suzu after she transformed into Oblivian.
===The True Value of Buddies===
Wishing to liberate the Phase 3 Deadman from their demons, Ikki and Vice underwent a VR training simulation to harness the Volcano Vistamp and combat against Orteca's Gifftarians, but were unable to be separated from their human hosts once created. Though Volcano Genome was powerful enough to defeat them, Ikki could not withstand the recoil of using the form and was hospitalized for bodily burns. Discouraged to fight, Vice encouraged him to face his burdens, which strengthened their bonds and allowed them to use Volcano Genome more efficiently. 
With Hiromi's dilemma with the Demons Driver becoming more apparent, Ikki began worrying about Hiromi's declining health which rendered him unable to operate as a Kamen Rider. During the operation to capture Orteca, Revice cleverly used a Rider Kick to separate Hiromi from the Demons Driver. After the battle, Ikki is informed about a demon inside the Demons Driver, making him suspicious of Fenix. Orteca deliberately had himself captured to acquire the belt and transformed into Kamen Rider Demons, becoming a powerful force who defeated the Igarashi siblings and knocked Hiromi off the cliff, seemingly killing him.
With Hiromi missing and Fenix being untrustworthy due to Vice's frequent afflictions from resonating with Giff, Ikki is given the Rolling Vistamp from an external source to treat his demon's condition. The Vistamp granted the duo acccess to Kamen Rider Jack Revice, but resulted in Ikki becoming incorporeal while Vice ran around in a physical form. Though Ikki was grateful for Vice's efforts to protect him, Ikki decided to accept George's help with the Vistamp and took control of Jack Revice for the first time. Ikki was restored to normal, however Vice had also merged with him. 
While attempting to adjust to their new situation, Ikki faced the resurgence of Vail and the return of his childhood memories regarding the fire. Learning that his father Genta was once transplanted with Giff's DNA, the Igarashi siblings are descendants of Giff. As Giff's revival approached, Vice became rampant and Ikki lost control of his body, causing him to subconsciously battle his demon. After saving him, Ikki and Vice harnessed the Thunder Gale Vistamp, uniting as Kamen Rider Revice. After defeating Orteca, Giff was fully revived but escaped into inactivity. Ikki and Vice were restored back to their own separate bodies.
===The Ultimate Unity===
Following Giff's complete awakening, Ikki and Vice would battle true Gifftarians created directly by Giff, just as Hideo Akaishi began to unveil his true colors. When he reunited with his old friend Koji Ikeda during a high school reunion, Ikki struggled to remember the memory regarding him accidentally injuring the former. Although he later reconciled with Koji, Ikki questioned why he was disappearing from the family photos. Vice revealed the condition of the contract to protect his family would erase his memories.
As the Igarashi siblings began fighting Akaishi, Vail reappeared and became a menace to the family. Akaishi proved to be many steps ahead of the Kamen Riders after turning Akemi into a Giffdemos and depleting most of Fenix's forces. While Ikki comforted Vice's worries about becoming like Vail, he also became concerned about Daiji's instability after several losses. He expressed that whole family should join forces to fight against Giff, despite Daiji prioritizing on saving mankind instead.
Together with Weekend, Ikki initially devised a plan to capture Akemi and extract Giff's cells from her body. However, the plan failed after Akaishi killed her and Daiji falsely accused him of letting Akemi die. To complete the Giffard Rex Vistamp, Genta elected to provide Giff's cells to his body. Despite the operation itself nearly killing his father, Ikki was able to stop it just in time. Before the Giffard Rex Vistamp flew back to Giff, Ikki and Vice were able to work together to split the Vistamp, allowing them to become Ultimate Revi and Ultimate Vice respectively.
While persevering in the demon war as Ultimate Revice, Ikki was forced to battle Daiji after the latter decided to cooperate with Akaishi and abandoned hope for humanity. Furthermore, every time he borrows the power of Vice, more Ikki's memories continue to disappear. Once the heroes finally come face to face with Giff, Ikki continues to transform into a Kamen Rider for the sake of his family and the world. In time, he would finally reconcile with Daiji and thus the Igarashi three siblings and their demons fully unite to destroy Giff for good.
===Price of Transformation===
Several weeks have passed and the Igarashi family returns to a peaceful life. While he is encouraged to make new memories, their peace would come to a halt after Karizaki became Kamen Rider Juuga on a mission to destroy every Rider System harnessing the power of demons. Although Vice elected to fight in Ikki's place to not worsen his memory loss, the idea failed after he was unable to recognize his own parents. With Karizaki being intent to threaten the Igarashis, Ikki has no choice but to confront him.
Although he remained conflicted, Ikki found a way to change Karizaki's heart after finding his childhood room. Convinced that it is necessary to defeat Juuga with Ultimate Revice, he decides to stop Karizaki even if he loses all his memories. The very next day, Ultimate Revi and Ultimate Vice fought Juuga and were evenly matched. Despite Karizaki's objections, Ikki asserts that he simply misses his late father Masumi and were able to save Karizaki's broken heart. In the aftermath, Ikki loses memories of Daiji and Sakura, asking Vice who they were to him.
After losing all memories of his entire family, Ikki tried to continue his daily life at Happy Spa, but he was unable handle things and decided to leave Vice. The pair relocated themselves to a new apartment and he went looking for a job. The next day, Ikki witnesses Vice going on a rampage in the city. He desperately pleads with his partner to stop, but is later stunned when Vice claims their experiences together was a lie. This sudden revelation angered Ikki enough for him to confront Vice, with both transforming into Ultimate Revi and Ultimate Vice to duke it out. While the two fought, Ikki deduced that Vice had pretended to go on a rampage with the help of their friends and allies.
Understanding Vice's intentions, Ikki decided to fight Vice on much friendlier terms. The playful battle between Revi and Vice became intertwined with several Genome Changes and Remixes, reminiscing their past battles. Once Vice began to vanish, Ikki held his partner in his arms and tearfully promises to reunite with Vice because he is family. With that, Vice disappears and Ikki's memories of his family are restored. A few months later, Ikki returns to normal life with his family and continues to aspire becoming a professional soccer player. During one family dinner, Ikki begins reacting in a strange yet familiar manner, before the family all laughed over his reaction.
One day after, Ikki goes outside and sees a box on his bike. After seeing what's inside the box, he was then visited by Ace Ukiyo, who politely takes the box from him and transforms into Geats.
===Kamen Rider Geats × Revice: Movie Battle Royale===
One year after they saved the Earth from Giff, life has continued on for the Igarashi family. As welcoming their newest member Koshiro into their lives, their demons also join them as part of the family. However Ikki is saddened to have no memory of Vice.
Whilst on vacation, the family are attacked by two aliens looking to extract Koshiro's inner demon to harness Giff's power. After being hospitalised due to suffering grave injuries in the attack, Ikki is able to call forth Vice upon the verge of his death. With Vice's return, Ikki regains his memories of his partner and the full strength of his Revice form. However, after defeating the aliens, Ikki must rescue the inner demon of Koshiro.
His rescue attempt eventually got him to reunite with Ace, as they recognized each other from when they saw last. With him, Ace and Vice being the victors of the first Desire Royale game, they proceed to the next game. Ikki would then use the Desire Driver temporarily to continue fighting as Riders.
After winning the Desire Royale, Ikki returns to his normal life while saying goodbye to Vice, who disappears again. However, this time, Ikki's memories of Vice stays intact due to Ace making a wish for Ikki to remember his partner forever.
==Other Events==
======
Kamen Rider Revi and Kamen Rider Vice arrived to challenge Asmodeus when he proved to be a formidable foe against the Kamen Riders and Super Sentai Rangers. While Vice made a dramatic entrance, Revi scolded him and pulled his tail. The surprise confused Kamen Rider Saber and Zenkaizer at first, but the heroes would soon watch as Revice working together to defeat Asmodeus with a Rex Stamping Finish before making their leave.
===Kamen Rider Saber===
Ikki as Kamen Rider Revi was chasing down Vice as the latter intruded Kamen Rider Saber and Espada's battle against the Batta Deadman. In the final battle, both Revi and Vice assumed the Megalodon Genomes to briefly slash it, before the Deadman was vanquished by Saber and Espada. After giving George Karizaki the Batta Vistamp, Ikki later passes out flyers to Touma Kamiyama and his friends to invite them to visit his family bathhouse before taking his leave.
==Personality==
Ikki is a hardworking young man who cares very much for his family and often times prioritizes them over everything else. However this would end up being detrimental to him and his effectiveness as a Kamen Rider where he'd treat the role as a side-gig, therefore not completely taking it seriously and inadvertently allowing people to come into harm's way as a result. Ikki is highly aware that his behavior ignores the trail of "losers" and victims he leaves behind, so he tries to make efforts to fix this trait of his while recognizing the weight of the responsibilities that come while fighting as a Kamen Rider.
Ikki is mellow and selfless, a trait that is often said to be inherited from his mother. As the "number one busybody in Japan", he will not hesitate to help anyone whom he sees needs it from the bottom of his heart. However, as pointed out by Yasushi Kudo, this is actually a sign of Ikki being unknowingly lacking in empathy, as he often acts against the wishes of others and does so without considering the consequences. Although Ikki told him that this was to satiate his own ego, he privately told Vice that when he gave up his dreams to play soccer, he also gave up on himself, admitting that he had, at some point, lost his will to live. As such, he began putting his attention onto others, hoping that their happiness would become his new reason to live. This is further explored through the revelation that his contract with Vice will inevitably cause him to lose all of his memories, and thus he ignores this for the sake of saving the world while believing that his own happiness comes from everyone else being able to remember him. In his final battle against George, he willingly gave up his own memories to ensure George's memories of his father were kept happy.
After ending his contract with Vice and regaining all of his memories of his family, Ikki goes back to his usual selfless and busybody attitude, though this time he also manages to move on and begin living a life for himself, resuming his passion towards soccer and overall becoming a lot more energetic and happier as a result. By this point, although Vice had already faded from existence, and Ikki had already completely forgotten about Vice, he begins adopting some of his inner demon's mannerisms much to his family's surprise, as Vice is still a part of Ikki after all.
Ikki's catchphrases are and .
==Powers and Abilities==
===Powers===
*Giff's Offspring Physiology: As a child of the man who is infused with Giff's DNA, Ikki can safely transform into a Kamen Rider using the Vistamp system.
*Inner Demon Control: Ikki possesses the ability to keep his inner demon Vice under control, enabling him to use the Revice Driver and Vice to appear as a corporeal being instead of a Deadman. As noted by George Karizaki, Ikki's ability to do this greatly enhances his power output as Revi, as seen with Volcano Rex.
*Demon Purging: Through the Volcano Vistamp, Revi can purge the demon form from contract-holders, as long as their human bodies still exist, unlike Gifftarians, where their host is consumed upon creation. This ability extends to Thunder Gale/Revice, with the power being strong enough to separate a Deadman merged with Giff's Coffin.
===Former Powers===
*Incorporeal Physiology: After the initial usage of the Rolling Vistamp, Ikki and Vice switched places, with Vice being permanently materialized and Ikki taking an immaterial form connected to the demon. During this period of time before they were able to switch back, Ikki had exhibited several physical characteristics similar to Vice in his original state:
**Imperceptibility: Ikki could not be perceived by anyone else other than Vice, having to possess the Gundephone50 in order to communicate and be seen by others. It is unknown if stamping the Rex Vistamp onto Vice would have been able to materialize Ikki the same way it did before with Vice.
**Intangibility: Ikki was completely intangible and could pass through everything, including his demon.
**Fourth Wall Interaction: While in his incorporeal form, Ikki was able to break the fourth wall just like Vice would usually do.
===Abilities===
*Expert Combatant: Because Ikki plays soccer, he uses his skills in battle for both evasive and offensive purposes. Examples include kicking in combat and performing slide tackles. Furthermore, Ikki was able to fight on even terms un-transformed against Azuma.
*Expert Soccer Player: Ikki is a soccer player who won multiple tournaments and awards throughout grade school.
*Public Bath Safety License: Ikki is a licensed advisor for public bath safety, which he uses to work at Happy Spa.
*Intermediate Illusionist: Ikki is capable of performing a sleight-of-hand magic trick using a piece of candy.
*Keen Insight: Although Ikki is not a professional detective, he is able to accurately analyze and deduce the harmful schemes of various individuals.
*Bilingualism: According to his Fenix profile, Ikki has achieved Level 3 on the National English Test, indicating that he can understand and speak English to an extent.
===Former Weaknesses===
*Memory Loss: As a young child, Ikki formed a contract with Vice to protect his family. This in exchange causes him to progressively forget significant parts of his past every time he fights as Kamen Rider Revi to the point he had forgotten daily routines of his life. Once Vice faded from existence, the contract was completed and Ikki regained his memories at the cost of forgetting Vice, though some muscle memory still remained. Vice along with Ikki's memories of him would be restored due to a near-death experience just prior to their participation in the Desire Royale. Although Vice's resurrection was temporary, Ace Ukiyo would use his latest wish as Deza Shin to allow Ikki to retain his memories of Vice and their partnership.
**Decreased Power: Relatedly, with Vice gone, Ikki can still transform but his power is diminished by "more than half."
*Giff: Due to briefly merging with Vice, Ikki also became affected by Giff's revival in a way that cause Vice to go berserk. The usage of the Thunder Gale Vistamp was able to bring Ikki and Vice in tune back together, freeing Vice from Giff's influence and restoring them both back to normal.

*Daiji/Kamen Rider Live: Daiji is Ikki's younger brother, often considered the prodigy of the family as he is a captain of Fenix. However, he has his own inner struggles that he refuses to disclose to Ikki and insists on having him sign the contract with Fenix. Daiji's hidden resentment towards Ikki had led to Kagero taking control, though with Ikki's renewed faith, Daiji was able to keep Kagero in check, and eventually even overcome his inner demon. However, the manipulations of Fenix's director had driven Daiji into desperation and despair, with his increasingly differing beliefs from Ikki beginning to drive a wedge in their relationship once more. The two would eventually mend their relationship as brothers after Daiji brought back Kagero and accepted his own demon as a part of himself.
*Sakura/Kamen Rider Jeanne: Sakura is Ikki's little sister. Ikki has a lot of trust in her, which she reciprocates. When Sakura gained the Libera Driver that allowed her to transform into Jeanne, it was Ikki who managed to help her work out her issues and help her transform into Jeanne. As her brother, Ikki does care for his sister a lot and does go out of his way to try to protect her but understands that she doesn't need protection from everything and has grown accustomed to her on the battlefield alongside himself.
*Yukimi: Yukimi is the mother of the Igarashi siblings who seems to understand each of her own children the most. She gives advice to Daiji and Ikki whenever they fight.
*Genta/Kamen Rider Vail/Kamen Rider Destream: Genta is the father of the Igarashi siblings. His antics sometimes lands Happy Spa into trouble, although Ikki hardly minds about this. When Ikki learned of Vail's existence as his father's inner demon, he was shocked, as he learns of his father's past as well and that Giff's cells were inherited from him.
===Friends===
*(Kamen Rider) Vice: At the first, the two were "frenemies", as Ikki did not like Vice's constant jokes about eating humans. Gradually their relationship became less antagonistic to the point where they became extremely close, with Ikki allowing Vice to roam around in his physical form. When the two switched places, Vice did his utmost best to keep Ikki from being captured by Fenix, feigning anti-heroism. When George is kidnapped by Orteca, Vice panics and proclaims to Sakura that he truly loved Ikki, which put a small smile on Ikki's face. After Ikki regained his childhood memories, he realized that Vice had protected him from mentally collapsing under intense trauma all these years. After Giff revived, Ikki made a vow to protect Vice this time not knowing that by doing so meant his memories will gradually disappear. By the time Ikki forgot his family, Vice selflessly worked out a plan with everyone else to have Ikki end his contract and regain his memories, at cost of Vice's disappearance.
=== Allies ===
*George Karizaki/Kamen Rider Demons (III)/Kamen Rider Juuga: George is the Fenix researcher who gives Ikki the Revice Driver and Vistamps to combat the Deadmen. At first, Ikki trusted him out of blind loyalty, believing George to be doing what is right. It wasn't until the events of the Demons Driver that Ikki started to doubt George's motives, something that Vice took a bit harder and absolutely refused to trust George. However, despite all the things happening around them, Ikki believe that George is someone they can rely on and managed to convince Vice of this.
*Hiromi Kadota/Kamen Rider Demons (I): Hiromi is a Fenix squad leader who assists Ikki in his battle with Deadmans after Daiji's supposed betrayal, while in reality it was Kagero who possessed Daiji. As they fought together, they became close and friendly with one another, acting like an uncle figure to him and the other siblings. When Hiromi was knocked off the edge of a cliff by a new christened Kamen Rider Demons (Orteca), he was devastated to a point where he began to lose faith in Fenix and those who were involved with Fenix (aside from his brother Daiji who took Hiromi's disappearance hard as well).
*Kagero/Kamen Rider Evil: Kagero is Daiji Igarashi's inner demon which was created from Daiji's secret resentment towards Ikki. As such, Kagero's existence is solely for Ikki's own destruction. Ikki did not hesitate to ask Kagero for help with the location of the Deadmans, agreeing to help him in exchange for food. Ikki witnesses the fight between Kagero & Daiji as Daiji becomes Holy Live. Realizing that Daiji's lost without Kagero (despite being a necessary evil), Kagero is brought back to life becoming an ally to Ikki as Daiji and him become truly one against Giff.
*Go Tamaki/Julio/Kamen Rider Over Demons (II): Once they were enemies. When Tamaki as Julio went Riot form after his best friend was killed by Orteca, Ikki saved him with Volcano Rex. Tamaki ends up working in the family bathhouse.
*Hana Natsuki/(Kamen Rider) Aguilera: Ikki saved Hana as Aguilera when the Deadmans' base collapsed. When attempting to free Aguilera from her demon, Sakura ended up stepping in to stop him.
*Masumi Karizaki: George's father of Weekend was responsible for sending a member of the group to deliver Ikki the Rolling Vistamp as a FENIX soldier, all for strengthening him and Vice against Giff.
*Hikaru Ushijima/Kamen Rider Over Demons: to be added
*Akemi Mikoshiba: FENIX's doctor who tells him of Hiromi's condition due to the Demons Driver's effects and how it's slowly aging him into an old man. When Akemi got too close to Akaishi's secrecy, she was drowned to despair, becoming a Giffdemons for Giff. Ikki & Vice tried to save her and she tells them before her untimely death that the only way to end Giff, is to use his own power against him.
*Nozomu Otani/Kamen Rider Chimera: to be added
===Enemies===
*(Kamen Rider) Orteca/Demons (II): Among all trio, Ikki harbored the strongest hatred to Orteca as he was the most manipulative and completely disregard of human's life, even his own allies.
*Yasushi Kudo: While facing Yasushi is just a daily mission that Ikki has to do, Ikki unintentionally made Yasushi out to be his arch enemy. Unfortunately, since Ikki is the one who has completely humiliated Yasushi's reputation while Ikki is supposedly to be an ordinary person in front of Yasushi. After Yasushi had been released by Aguilera and Amahiko, Yasushi glared at Ikki as the sign to be his ultimate target.
*Giff: While intent on preventing his awakening, it was revealed Ikki and his siblings have Giff's genes in their DNA.
*Vail: Vail is his father's inner demon who was sealed away in various Drivers since he was separated from Genta. Vail believes that he and Genta do not have a need for a family and therefore resents Genta's family, hoping to destroy them all, which Ikki would not allow to happen without a fight.
*Azuma/Kamen Rider Daimon: to be added
===Others===
*Ayaka Oketani: Ayaka is a childhood friend of the Igarashi siblings, though Ikki has a noticeable crush on her. Ayaka however was the contract holder of the Kong Deadman.
