Masaki Segawa is the author and illustrator of the Japanese manga series Basilisk. Based on Futaro Yamada’s 1958 novel The Kouga Ninja Scrolls, it was serialised in Kodansha’s Young Magazine Uppers from 2003 to 2004. The storey is set in the year 1614. Two ninja clans, the Iga of Tsubagakure and the Kouga of Manjidani, compete to see who will be the next shogun, the grandson of Tokugawa Ieyasu. The deadly competition between ten elite ninja from each clan reawakens a centuries-old hatred that threatens to destroy any hope of peace between them.

Basilisk Anime Synopsis

For centuries, the Iga and Kouga ninja clans have been at odds. However, when the powerful warlord Ieyasu Tokugawa orders a ceasefire, the two clans are forced to lay down their arms.
Years later, Gennosuke Kouga, the Kouga clan’s heir, and Oboro Iga, the Iga clan’s heir, have fallen in love. Both heirs hope to bring peace to the clans through marriage. Their hopes are dashed, however, when rivalry between their clans rekindles and they are dragged into another war.

Ieyasu’s two grandsons have both claimed to be the next shogunate heir. To settle this dispute, the Kouga and Iga are both ordered to send their ten best warriors to a bloody battle royale, with each clan representing one of the potential shogunate heirs. Two scrolls with the names of the fighters are given and are to be inscribed in blood upon the death of the given fighter. The Tokugawa shogunate’s favour for a thousand years is the prize for victory. Gennosuke and Oboro must ultimately decide the fate of their clans, torn between their love for each other and their duty to their clans.

Basilisk Anime Characters

In the Basilisk universe, there are three main groups of characters, the Kouga Ninja, the Iga Ninja and others that are associated with the shogun. In the second season, The Ōka Ninja Scrolls, a number of new characters are introduced.

Kouga Ninja

The Kouga are experts in assassination and stealth, employing techniques that rely heavily on deception. Even battle-oriented abilities, such as Gennosuke’s Dojutsu, tend to be defensive in nature. A number of new characters are introduced in the second season, The Oka Ninja Scrolls.

Gennosuke Kouga

Gennosuke Kouga is the heir to Kouga Danjou and takes over as clan leader after his grandfather’s death. Gennosuke, an idealist and scholar who believes in looking to the future rather than being dominated by the past, sees the pursuit of any grudge as ultimately futile and self-destructive. Even after learning of the Hattori Truce’s absolution, he leads the Kouga on an expedition to Sunpu to beg former Shogun Ieyasu and Hattori Hanzou to reinstate the treaty before any further bloodshed occurs. Despite being a man of peace, Gennosuke is more than capable of killing anyone who threatens him or his clansmen if pushed into a corner. In addition to his sword skills, Gennosuke possesses a power known as Dojutsu, which was passed down through his family line. Dojutsu, a hypnosis technique, gives Gennosuke the ability to reverse the homicidal intent of anyone who directly meets his gaze, effectively causing them to kill themselves instead of him. Because of his strength, the Iga levels the playing field by temporarily blinding Gennosuke with the same Seven Days of Darkness ointment that Oboro used on herself.

Prior to the resumption of the conflict, Gennosuke attempted to end clan hostilities by marrying the Iga Princess Oboro, whom he adored. His feelings for her persist even as the death toll among both clans rises, tormenting him as he struggles to reconcile his personal feelings with the duty demanded of him as his clan’s leader. In the anime, Gennosuke carries a flute that he frequently plays for Oboro and that represents their hope of bringing the clans together in peace.

Gennosuke eventually accepts, unable to avoid confronting Oboro, that she will kill him. Instead, Oboro kills herself, and Gennosuke writes in the scroll that Oboro was the last person to survive before joining her in death.


Kagerou is a stunningly beautiful woman who is also a skilled fighter (she carries a shikomizue in her walking cane and is highly adept at shurikenjutsu). Kagerou’s sensuality is her most lethal weapon, as her breath turns poisonous when she is sexually aroused, a skill passed down from her mother. She is madly in love with her superior, cousin Kouga Gennosuke. But, because of Gennosuke’s feelings for Oboro and her own technique, she is unable to be with him emotionally or physically, resulting in a jaded persona full of envy and bitterness. Kagerou’s favourite target for her rage is Oboro, and she was one of the more vocal opponents of her and Gennosuke’s marriage, quick to belittle and criticise Oboro at every opportunity. Kagerou was tortured to death after being apprehended by Tenzen following an attempt to assassinate Oboro. Kagerou attempts to kill Gennosuke in her final moments, believing that the Kouga were doomed to defeat and desiring to die with the one she loves, but is stopped by Oboro using her eye technique.

Kisaragi Saemon

Kisaragi Saemon, Okoi’s elder brother, conducts himself with an almost professional sense of detachment in both war and peace. His sister is the only person to whom he expresses genuine emotion. Following Okoi’s capture and death at the hands of the Iga, Saemon throws himself wholeheartedly into the war between Koga and Iga, seeing victory for his clan and vengeance for his sister as synonymous. Throughout the battles, Saemon comes to understand, and even agree with, Gennosuke’s views on the futility of vengeance. Nonetheless, he recognises that the hostility on both sides makes reconciliation an impossibility.

Saemon is a stealth and infiltration expert who can assume the identity of another person by pressing their face into a raised mound of mud or soft clay, forming a mould into which he can insert his own face to assume their appearance. This, combined with his ability to impersonate voices, makes Saemon a master of disguise. His technique, on the other hand, is only cosmetically effective. It does not bestow any of a person’s memories or abilities on him, and anything with senses superior to a human’s (as Hotarubi’s snake demonstrated) can see through it. Saemon is also a capable fighter, having successfully defended himself against multiple Iga ninjas at one point. Tenzen violated the honour code of the two clans and enlisted the help of Lady Okufu’s vassals to gain the upper hand, and Saemon is impaled through the torso atop a bridge, making him the only ninja to be killed by forces other than Kouga or Iga. By the end, Saemon had killed Hotarubi and helped to kill three other Iga ninjas (Yashamaru, Koshiro, and Akeginu).

Muroga Hyouma

Muroga Hyouma is Gennosuke’s uncle and Danjo’s second in command. Hyouma, like Gennosuke, possesses the Doujutsu technique and was the one who first taught Gennosuke how to use it. Unlike Gennosuke, Hyouma’s Dojutsu is always active, so he must keep his eyes closed or risk killing the wrong person at the wrong time. To compensate, Hyouma develops an almost radar-like hearing ability, making it impossible for him to be snuck up on. Hyouma’s Doujutsu is only effective at night. Despite his mistrust of the Iga, Hyouma recognises that no matter how different people are, they are still humans who live, feel, and die in the same way. Because of Hyouma’s teachings, Gennosuke was able to see past his clan’s hatred for the Iga and attempt to establish peace, which Hyouma wholeheartedly supports. When Mino Nenki underestimates his two blind opponents, Hyouma and the recently blinded Gennosuke, he easily kills him with his Doujutsu. In a duel with the now-blind Koshirou, he is killed. Hyouma couldn’t use his Doujutsu on Koshirou because he was blind. Koshiro slashes Hyouma’s ear, destroying Hyouma’s ability to locate his opponent via hearing. Despite the fact that Hyouma dies, he remains on his feet in the end.

Kasumi Gyoubu

Kasumi Gyoubu is tall, bald, and powerfully muscled, and he can break an enemy in half with his bare hands. He, like Saemon, specialises in infiltration and stealth. Gyoubu gains cover to move and attack in complete secrecy, as well as manipulate any object in physical contact with the surface, by using his technique to merge into any solid surface. Because the technique can only be used by his body, he must strip naked and lay down any weapons he carries in order to use it. He despises the Iga because his father, Renbu, was murdered by an Iga squad years before, and Gyoubu vowed to one day exact revenge because his father’s last words were to never pity any ninja. However, the Hattori truce was imposed on both clans soon after, and Gyoubu shaved his head to express his unsatisfied rage.

In the anime, Gyoubu has an uncle/niece relationship with the tomboyish Okoi, whom he frequently takes hunting wild boar in the forests surrounding Manjidani. There is no mention of his backstory in the manga, and his baldness is due to a medical condition rather than a display of hatred.


Okoi embodies the popular concept of the Kunoichi, being tomboyish and energetic with a well-endowed frame (in contrast to both Akeginu and Kagerou who embody the more historically traditional version). She has a close relationship with her older brother Saemon and is one of the few people who can make him smile. Okoi also has a strong friendship with the normally unapproachable Gyoubu, with whom she frequently goes to hunt wild boar in the forests surrounding Manjidani in the anime. Although she is a capable fighter, Okoi is not opposed to using her numerous assets to entice men into a false sense of security if necessary. When they make the mistake of making physical contact, Okoi is able to adhere her skin to her opponent’s and absorb their blood into herself, leaving her opponents as dried up husks. Okoi must vomit out the excess blood after finishing the technique before she can use it again. She is dressed in a more revealing manner than the other kunoichi, with a hip length sleeveless kimono and shortened hakama that resemble Daisy Dukes, because more contact equals faster blood drain. Nenki killed her by stiffening his hairs into needles and impaling her in multiple places, leaving her to die on the floor.

Udono Jousuke

Udono Jousuke is a good-natured, a little dumb, and extremely fat ninja who defies the traditional ninja stereotype. And, as his interactions with Akeginu demonstrated, he’s also a bit of a lecher. Jousuke is more perceptive than he lets on, and during his stay with Gennosuke in Tsubagakure, he was the first to notice the Iga were planning something suspicious before they silenced him. Furthermore, despite his corpulent appearance, Jousuke possesses remarkable speed and agility for a man of his size, as evidenced by his ability to easily avoid the attacks of both Rousai and Akeginu, two of the Iga’s strongest fighters.

His obesity is also the key to his technique, as it gives his body the consistency of rubber, allowing him to bounce like a ball, roll over enemies like a living boulder, deflect physical attacks with ease, squeeze through openings impossible even for someone a quarter of his girth, or even float into the sky by rapidly inhaling air and blowing himself up like a balloon. Jingoro kills him for being too arrogant while he had the upper hand. Despite his untimely death, he was most likely one of Kouga’s strongest ninjas. Despite her intent to kill him, Jousuke easily defeated Akeginu without realising the treaty had been broken. Also, when told that Jousuke was with Gennosuke, the impatient Gyoubu was slightly calmed, and he even thought Jousuke and Gennosuke had already defeated all of the Iga ninja.

Iga Ninja

Rather than relying on deception, the Iga prefer more direct methods and their techniques tend to be mostly offensive to better give them an edge in close combat situations.


Following the death of Ogen, Oboro ascends to leadership of the Iga clan, only to have her authority usurped by Tenzen. Oboro, who was born with “mystic eyes,” has the ability to neutralise the techniques and special abilities of any ninja who comes into direct contact with her gaze. This power is always active and has the potential to affect both enemies and allies. Prior to the lifting of the Hattori truce, Oboro is engaged to Gennosuke Kouga in an attempt to bring both clans to a lasting peace. In the anime, Oboro and Gennosuke would frequently meet along their clan’s borders to practise a Japanese fan dance that they planned to perform for their wedding guests.

Oboro, who has a gentle disposition and a sweet disposition, lacks any real talent for martial arts or ninjutsu and is also a bit of a klutz. This, combined with her love for Gennosuke, has led to the majority of Iga viewing Oboro as a black sheep, a fact she is painfully aware of. When the Hattori truce is broken, the other Iga seize the opportunity to exploit Oboro’s feelings for Gennosuke by tricking her into inviting him and Udono Jousuke into their compound, where the Iga can keep them under surveillance. Oboro, despite being hurt and betrayed by their actions, remains loyal to her clan and is torn between duty and emotion when the truth of the renewed conflict is finally revealed to her. Finally, she decides to temporarily close her eyes with a potion called the Seven Days of Darkness given to her by Ogen, knowing that if she sees any of her clansmen attacking Gennosuke, she may be tempted to use her powers against them instead. Despite her best efforts, Oboro is forced to face a blinded Gennosuke in the final episode when Lady Ofuku and her faction enter the conflict. She refuses to kill Gennosuke in order to both defy her fate and make amends for the Kouga her clansmen have killed. Instead, she approaches him, tells him she loves him, and then commits suicide, taking her own life.

Yakushiji Tenzen

Following Ogen’s death, Yakushiji Tenzen, Ogen’s second in command, is able to seize control of the Iga from Oboro and become the Iga’s de facto leader. Tenzen appears to be a pragmatic fighter solely concerned with the honour and future of his clan, but he is actually a sadistic and malicious individual who thrives on conflict and bloodshed. He fights with ruthless tenacity and will not hesitate to involve innocent bystanders in order to win. He also lusts after Oboro and wishes to marry her in order to become the true lord of the Iga, even if it means raping her, which he attempts at least twice throughout the series. Tenzen’s technique, like Himura Genma’s from Ninja Scroll, is one of regeneration and immortality. Tenzen was born with a symbiotic being that normally conceals itself so that only its closed eyes are visible as a wart/growth on Tenzen’s ears. When Tenzen is wounded or killed, the creature awakens and moves through his body to regenerate him by “eating” his wounds, restoring whatever ravages of time or battle Tenzen may have suffered. Tenzen was well over 200 years old by the time Basilisk was born, thanks to his abilities, though he appears to be no older than 30. Tenzen can regenerate even after being decapitated if someone holds his head to his body while his symbiote seals the cut.

Ogen tells Oboro in the manga that the symbiote creature is Tenzen’s twin brother, with whom he merged inside their mother’s womb shortly before birth. However, in the anime, Ogen stops just before telling Oboro where she believes the parasite originated, leaving its identity ambiguous. Tenzen’s backstory is also expanded slightly in the anime, with his mother revealed to be an Iga woman who was murdered by her lover (a member of the Kouga ninjas and Tenzen’s father). Tenzen was then extracted from his mother’s womb and raised as a Kouga. Years later, the Adult Tenzen defected to the Iga, where he secretly manipulated both clans into retaining their hatred for each other in the name of his own vengeance, unbeknownst to the others.


As Princess Oboro’s bodyguard and confidant, Akeginu is more forgiving of Oboro’s lack of ninja skills than the rest of their clan, treating her almost as an older sister. Regardless, Akeginu’s first loyalty is to the entire Iga, and when word of the Hattori Truce’s absolution reaches her, she has no qualms about deceiving Oboro while assisting her clansmen in their attempt to assassinate the Kouga ten, including Gennosuke. Despite her responsibilities, Akeginu sympathises with Oboro’s situation and is one of the few members of Iga, aside from Tenzen’s apprentice Koshirou, who does not shun her after Oboro’s decision to seal her eyes. She even keeps the flute Gennosuke left behind in Tsubagakure safe from the other Iga so Oboro will have a memento of him after the war is over. She also has feelings for Koshirou, whom she wishes to marry.

Chikuma Koshirou

Chikuma Koshirou, a Tenzen apprentice, uses his breath to create miniature whirlwinds that suck his enemies in and shred them to pieces. He also carries two kama hand scythes, which he can use in close combat or throw like boomerangs. Tenzen dispatched Koshirou to eliminate Gennosuke after learning of the Hattori Truce’s absolution. When Oboro tried to stop the fight, Gennosuke used his Dojutsu to turn Koshirou’s whirlwind back on himself, destroying Koshirou’s eyes completely. Koshirou gradually learns to compensate by using his other senses, but he still requires some sort of assistance to fight effectively.

Koshirou and Oboro grew up together, and despite their different stations, she considers him to be her older brother. Koshirou is completely devoted to Oboro, and it is even implied that he has romantic feelings for her. His devotion to Tenzen compels him to obey his sensei’s orders regardless of how he feels. He’s also Akeginu’s love interest, despite the fact that he’s mostly unaware of it. In the anime, Koshirou is an expert woodcarver who, after losing his sight, learns to carve with equal skill using only his sense of touch. Of all of Basilisk’s characters, Koshirou differs the most between the anime and the original manga, where he shares Tenzen’s ruthlessness and arrogance in combat, whereas the anime depicts him as being more hesitant to fight any battle where his opponents would be at a significant disadvantage.
