Character History

Kyuemon Teenager

Human form

Long ago, Kyuemon Izayoi was a ninja who held a huge proficiency in ninjutsu. Eager for an apprenticeship, Yoshitaka Igasaki took Kyuemon under his wing and trained the latter to follow his footsteps. Kyuemon trained with Tsumuji Igasaki as ninjas, with Kyuemon showing more in terms of proficiency and lack of hesitancy. When Yoshitaka derided Tsumuji for being so hesitant and lacking nintality, Kyuemon stripped Tsumuji's of his ninja powers and memory, seeing this as the only logical choice. He did so just before the Last Ninja caught him. Shinobi 29: Definitive Edition Ninja Sugoroku! Sometime later, Kyuemon became fearful of the power, and defected from Yoshitaki. Kyuemon eventually fell to darkness and turned into the Kyuemon the Ninningers know now. Shinobi 13: Burning! Ninja Sports Day According to a conversation Kyuemon had with Kinji, the betrayal was because Yoshitaka refused to hand over the End Shuriken. Shinobi 15: Youkai, I Never Failed

Kyuemon first orchestrated the destruction of the Igasaki Dojo home. Kyuemon picked up a mallet from the burning ruins within a box by phasing through it while Hitokarage fought Takaharu as AkaNinger. Kyuemon later appears at the site where Gengetsu Kibaoni was sealed, and with the pilfered mallet, used it to free him from his sealed state, leading to the full revival of the Kibaoni Army Corps. Shinobi 1: We're Ninja!

By collecting human fears, Kyuemon resolves to revive the other generals of the Kibaoni Army Corps starting from Raizo Gabi Shinobi 2: Become the Last Ninja! and later tried to resurrect Gengetsu Kibaoni with it. Kyuemon began a search for the End Shuriken in the hope of reviving their master while knowing that his nemesis, Yoshitaka Igasaki has grown weaker in his older days. Shinobi 6: Tengu's Spiriting Away

After Raizo Gabi's death, Kyuemon used the fears he collected for him to revive Masakage Tsugomori, Kibaoni's Chief retainer, who knows that Kyuemon is not an original member of the Kibaoni Army Corps. Masakage threatened to kill Kyuemon should there be any betrayal. Shinobi 13: Burning! Ninja Sports Day Following Youkai Futakuchi-onna's demise, Kyuemon approaches Kinji, a wannabe student of Yoshitaka and offered him an apprenticeship, in hopes of using him to proceed with the plans. However, after thinking it over, Kinji attacked Kyuemon, saying he had been a fool for being tempted by someone who disobeyed the Last Ninja. Disappointed, Kyuemon said that an OtomoNin that he had created not only disobeyed him, but abandoned him as well. Kyuemon said that it was called the Sky OtomoNin, and that hopefully Kinji wouldn't live to regret his decision before leaving. Shinobi 19: Search For It! The OtomoNin of the Sky

For his third Izayoi Way Ninja, Puppet Ninja Kuroari, Kyuemon intended him to recruit children into the Kibaoni Army Corps, with Masakage overseeing this plot. Having Kuroari use his Parasite Technique to control the ninja master, Kiroku Ise, the manipulated Kiroku then set up a ninja school to find potential ninja initiates. However, Kiroku's apprentice instructor, Kikyo Kousaka, turned out to be an acquaintance of AkaNinger, introducing him to the school where he noticed suspicious behavior from Kiroku and his students, leading Ao, Momo and StarNinger to investigate Kiroku who convened with Masakage, who intended to use Kikyo's conflicting feelings against Takaharu. Engaging the three Ninningers to prevent them from getting through to Takaharu, Masakage was forced to retreat when StarNinger escaped. Ultimately, the plot was foiled when Kikyo's faith in Takaharu led to the truth being revealed as Kiroku was freed from the manipulation of Kuroari, who was subsequently defeated by the Ninningers. While observing that Kuroari had fallen, Kyuemon proclaimed that he had served his purpose as he gathered his first three ninja's Core Gears. Shinobi 30: Targeted Ninja School!

Later it was revealed that he wanted the Izayoi Way ninjas to be defeated in order to collect the core gears to power the Karakuri Kyuubi, using it he nearly killed Shishi-oh and put the other OtomoNin out of commission throwing the Ninningers out of them. He later confronted them on the ground intent on destroying them and would have if it weren't for the intervention of Yoshitaka Igasaki who whisked them away to safety while unintentionally letting Kyuemon know that he is in possession of the End Shuriken. Later, as the Ninningers fought Mujina using Gekiatsu Dai-Oh, Kyuemon uses Karakuri Kyuubi to backstab him. However, while fighting Gekiatsu Dai-Oh, the Ninningers determined strength ends up overpowering Kyuubi. Then, they finish off Kyuubi with Kyuemon inside using the Gekiatsu Dai Fever. Shinobi 32: Extremely Hot Ninja! Acha!

While thought to be dead after Karakuri Kyuubi was taken down, Kyuemon ends up hiding in secret, wearing a cloak, now scarred from the previous battle. Kinji then searches for him in hopes of finding a cure to the You-Power in his body. Kyuemon tells him of the cursed demon sword Urusame that will absorb its power. They are both targeted by Advanced Yokai Oumukade due to orders from Tsugomori. After telling Kinji that he can go back to his friends, Tsugomori then finds him. As Oumukade is destroyed by Gekiatsu Dai-Oh, Tsugomori confronts Kyuemon for his deception, but Kyuemon tells him that his plan was to overwhelm Kinji into a Yokai with the cursed sword. Shinobi 35: Kinji Enters the Yokai Labyrinth! Then, as Kinji struggles to fight the You-Power, Kyuemon appears before Yoshitaka to tell that he'll save Kinji if he gives the End Shuriken to him, but he refuses. Kyuemon then enters Kinji's mind, uses his visage alongside other Yokai, and tells him that being a Yokai helps him disregard any struggles or doubts. But Kinji refuses, and at Yoshitaka's command, Kinji slays the spirits out of his mind, resulting in Urusame becoming the Gekiatsuto. After Tsugomori's defeat by StarNinger, Kyuemon curses in anger as he leaves. Shinobi 36: Kinji, the Glorious Super Star

After Mangetsu Kibaoni's defeat, Kyuemon revealed his secret to him before he died - he is Mangetsu's older brother, the eldest son of Gengetsu Kibaoni! Shinobi 42: OtomoNin Wars! Nekomata Strikes Back He then proceeds to tell Ariake no Kata about Mangetsu's demise to where she cries and with this massive despair, Kyuemon gathers all of it to resurrect his father. Shinobi 43: The Legendary Ninja! Yokai Karuta Tactics

Following Gengetsu's revival, the general reveals to Tsugomori and Ariake no Kata that Kyuemon is his illegitimate son, bore to him by one of his concubines and thrust into the future by Yokai power. Tsugomori apologizes to Kyuemon for his previous threats and insults towards him. Kyuemon tells him it couldn't be helped and orders him to gather fear and deal with the Ninningers. Shinobi 44: The Final Battle! The Ordeals of the Last Ninja

After assigning Raizo Gabi to take out the Ninningers and is easily defeated, Kyuemon then approaches them next, telling them them that to become the Last Ninja, they must slay their grandfather, to where he'll be the one to do so. They essentially struggle in fighting Kyuemon at that rate. Eventually, they soon learn and decide to go into a new direction of being the Last Ninja and fight Kyuemon with new, unexpected techniques. After they finish Kyuemon, the stolen Nintality he had exits his body. Tsumuji, who was watching the battle, takes the opportunity to claim his stolen Nintality back. A thoroughly vexed Kyuemon decides to charge back, but Raizo Gabi appears and tells him to stand down as they soon leave. Shinobi 45: Three Generations of Fathers and Sons! All Ninjas Gathered

During the climatic battle against Gengetsu Kibaoni, Kyuemon successfully seized the End Shuriken from his former mentor Yoshitaka while he was distracted in his battle with Gengetsu. But as Yoshitaka vanished, he imparted a single Sealing Shuriken to Kyuemon. With the Last Ninja vanquished, Gensetsu would empowered Kyuemon with five Sealing Yo Shuriken, transforming him into Sakuya Kyuemon, a yokai of incredible power. Though the Ninniger would fight valiantly against the Kibaoni Army, Kyuemon would eventually activate the power of the End Shuriken in the form of the Shukyoku Nin Shuriken (終極忍シュリケン Shūkyoku Nin Shuriken?, Ultimate Nin Shuriken) to spread darkness throughout the land, even severing the Nintality of the Ninninger, leaving them powerless. Shinobi 46: The Last Shuriken Appears!

Takaharu and his team rally and regroup against Kyuemon creating new Nintality to transform and defeat him. The battle leaves Kyuemon in his original Yokai form, distraught that he was supposed to be the one to surpass Yoshitaka, not them, but Takaharu decides to approach him about the fact that he admired Yoshitaka. Kyuemon denies this, but the rest of the team understood his ambitions and feelings from his actions. Kinji even compares this to his own motives of wanting to reclaim their families. Soon, the Sealing Shuriken Yoshitaka gave to Kyuemon appears, turning into a blank green Nin Shuriken. Being told that it was a sign of Yoshitaka wanting him back as a student, Kyuemon is doubtfully surprised by this. However, Gengetsu reappears. Telling him that he can't escape fate and grabbing him on the neck, he absorbs Kyuemon to enlarge himself. But thanks to the combined efforts of Ninningers, they release Kyuemon from the giant Gengetsu before they finish him off once and for all. After Gengetsu's defeat, the weakened Kyuemon sees the spirit of Yoshitaka for the last time before he fades, leaving the End Shuriken behind to the Ninningers. As the Ninningers save the world by wishing for one without the End Shuriken, Takaharu hopes of Kyuemon being reborn a ninja through the green Nin Shuriken he retrieved as a memoir. Shinobi Final Chapter: To a Future Without Hiding, Wasshoi!

The blank green Nin Shuriken, now housed in the Igasaki home, is later used by Sakurako Igasaki to recruit a new "Ninnin Girl" to fight alongside Kasumi Momochi and Fuuka Igasaki against the "Ninnin Boys" for right to be THE Igasaki ninja team. With the Nin Shuriken given to Luna Kokonoe, Kyuemon comes to possess her and redeem himself as a ninja. Now a woman, she proves this by revealing herself to the Ninningers when the Youkai threat returns, saving their life and fighting by their side as a team member. With the threat eliminated, Kyuemon departs from Luna's body and disappears into the ether. Come Back! Shuriken Sentai Ninninger: Ninnin Girls vs. Boys FINAL WARS

Video Game appearances

Super Sentai Battle Base

Kyuemon Izayoi is among the vast pantheon of villains which appear in the mobile game Super Sentai Battle Base.

Shuriken Sentai Ninninger: Game de Wasshoi!!

Kyuemon Izayoi appears as an enemy in Shuriken Sentai Ninninger: Game de Wasshoi!!, where he appears to enlarge the Yokai as on the show.


As mentioned by Yoshitaka, Kyuemon was skillful and active in his early days as a ninja, and eagerly willing to become his student. But eventually, after developing fear of the Ninnin power, Kyuemon went astray and betrayed his teacher, ultimately falling to the dark side.

After joining the Kibaoni Army Corps, Kyuemon holds a huge loyalty for the master of the Corps and faithfully fulfills his desire to gather human fears. Kyuemon's turn to the Kibaoni Army Corps had made him a stoic and calculating person. Due to this, even though Kyuemon is capable of controlling patience such as when dealing with Raizo Gabi's lust for fighting, Kyuemon is still easily aggravated by flighty or playful persons like his former teacher Yoshitaka and Tsugomori.

Powers and Abilities

Kyuemon was able to retrieve his mallet from a box without opening it.
Yo Shuriken Abilities
Kyuemon Izayoi uses the ill-gotten mallet to set a Yo Shuriken in it, utilizing it in a way similar to the Ninningers and their Ninja Ichibantou.
Yo Shuriken Creation
If one of Yoshitaka's purified Sealing Shuriken were to fall into Kyuemon's hands, it can be converted into a Yo-Shuriken.
Kyuemon can fly by creating a black Shuriken energy construct to step on.
Kyuemon can unleash a powerful gust of wind by simply outstretching a hand to the target.
Yōjutsu (妖術? lit. "Demon Technique")
As one of Kibaoni Army Corps' general, Kyuemon has knowledge of dark magic. It is possible that since Kyuemon was a former student of Yoshitaka, the Yojutsu techniques were simply based on the Last Ninja's Shuriken Ninja Arts, albeit warped and corrupted. While most of the techniques made in conjunction with Kyuemon's mallet and Yo Shuriken, there are a few unique to him.
Thunder Summoning Technique (雷招来の術 Ikazuchi Shōrai no Jutsu?)
One of Kyuemon's attacks- can generate a lightning bolt from his hands.
Kyuemon can teleport by engulfing the body with purple flames.
Kyuemon can put out or generate fires with the wave of a hand.
Fire Fox Technique
Kyuemon can create a small stream of fire that detonates into a violent explosion upon reaching its target.
Inferno Cross Technique

Kyuemon focuses his ninpo energy into a field of purple flaming cross projectiles that surround the target in a dome-like formation and then bombards them with the projectiles.


Mallet and Yo Shuriken
Kyuemon wields a small golden ceremonial mallet stolen from the ruins of the Igasaki Ninjutsu dojo, which can be augmented with a Goton Yo Shuriken, which allows the use of Yōjutsu. The mallet itself can also being used in multiple ways, among them are:
  • Transforming into a sword.
  • Yojutsu: Hidaihansoku Technique (妖術・肥大蕃息の術 Yōjutsu: Hidaihansoku no Jutsu?, a 4-kanji proverb meaning "to grow and multiply rapidly")
Kyuemon's most commonly used Youjutsu. Performed by using the Goton Yo Shuriken, this technique is used to revive and grow Yokai. This technique can also grow non-Yokai, such as RoidmudesIcon-crosswiki, as seen in the incident in the Kamen Riders' world, Shuriken Sentai Ninninger Vs. Kamen Rider Drive Spring Vacation One-Hour Combining Special or even the Ninningers as demonstrated when Yokai Mataneko inadvertently enlarged AkaNinger Chozetsu after taking Kyuemon's mallet. Shinobi 26: It's Summer! Last Ninja Race Intermediate Announcement!
  • Used as a makeshift fishing rod.
Gourd Container
As the Kibaoni Army Corps commence their acts of villainy, this special Hyotan gourd gathers the "Power of Fear" as some form of liquid. The gourd must be near to work, so Kyuemon is often close by when the Kibaoni forces are creating havoc.
Karakuri Kyuubi
Kyuemon's personal mecha made in his own likeness.

Behind the Scenes

  • Height: 184 cm (194 cm: Ultimate form)
  • Weight: 194 kg (205 kg: Ultimate form)


Kyuemon Izayoi is voiced by Megumi Han (潘 めぐみ Han Megumi?). His suit actor is Yuichi Hachisuka (蜂須賀 祐一 Hachisuka Yūichi?). As a teenager, Kyuemon is portrayed by Ryusei Takeba (竹場 龍生 Takeba Ryūsei?).


  • While initially either gender-ambiguous or feminine, Izayoi was revealed to be male in the second arc of the show.
  • The "Izayoi" of his false surname refers to the "16th day moon", which is commonly known as the "full moon". This served as foreshadowing of his true origins.
  • Kyuemon's motif and name are based on the nine-tailed kitsune (九尾の狐 Kyūbi no Kitsune?), and as such he sports an incomplete kitsune mask from Noh theatre. Considering Kyuemon's white pelts, the design could be an evil parody of the messengers of the Shinto god Inari, the Zenko (善狐? lit. "Good Fox"), which are said to take the form of white foxes.
    • Ironically, while kitsune are often portrayed as playful animals, Kyuemon is stoic and persistent in outlook, though there are certain scenes which tied to the kitsune motif, being a cunning strategist to the Kibaoni Corps and having betrayed Yoshitaka to join said team, using his teachings against him and his grandchildren.
  • The mallet's shape is a reference to the Uchide no Kozuchi, the legendary Lucky Hammer. In the fable Issunboushi (One-inch boy), a boy the size of a thumb defeats an oni, steals his mallet, and uses it to become a full sized man (and marries the princess).
    • The Lucky Hammer also appeared in an episode of GoGo Sentai Boukenger, where it was used to make human-sized opponents giant sized.
