Momiji (紅葉?) is Kureha's younger sister and Ryu Hayabusa's apprentice who first appears in Ninja Gaiden Dragon Sword. She later appeared as a playable character in Ninja Gaiden Sigma 2 and an NPC in both Ninja Gaiden 3 and Yaiba: Ninja Gaiden Z. Like Kasumi, she is available as a free DLC Character in Ninja Gaiden 3: Razor's Edge for the Wii U system and as an unlockable character for the Xbox 360 and PS3 systems.
Momiji is young girl with hazel eyes and long black hair tied in a ponytail. She originally wore a white standard Hayabusa ninja garb, but later adopts an outfit with a sleeveless white top with red ribboned edges, red kunoichi styled pants, and black and gold high-heeled boots.
Momiji is a very gentle and caring young woman who is seen by the village children as an older sister figure, whom they look up to.
Like her mentor Ryu Hayabusa, Momiji has a strong will and refuses to accept any vulnerabilities and trains extensively to become one of the deadliest warriors in the Hayabusa village.
Along with her older sister Kureha, Momiji was raised to be a Dragon Shrine Maiden. She was tasked with keeping the ancient relics passed down the Hayabusa Village from the ancient Dragon Lineage and carrying out the Shrine Maiden's rites and rituals to purify the world of malicious evil forces.
Unlike Kureha, Momiji was spared the fate of her older sister during the Dark Dragon Blade Incident. At the time, Momiji was away from the village on an errand only to come back to a ruined village. She was devastated by the loss of the many lives, especially her elder sister.
Momiji began training under Ryu as a precaution and ended up becoming a skilled kunoichi along with her Shrine Maiden abilities for the sake of the Hayabusa Village. She supports and follows her master whenever he comes around.
Ninja Gaiden: Dragon SwordEdit
After training in the Forest of Shadows with Ryu, as she had done everyday since the attack on the Hayabusa Village, Momiji tells him to go ahead while she stays behind to pick flowers for Kureha's grave, as she had promised to Sakura earlier. Unfortunately, while picking flowers, she is attacked by the Black Spider Clan, under the order of elder sorceress Obaba, to retrieve the ancient relics of the Hayabusa clan. Though she manages to kill many Black Spider ninjas, she is overwhelmed by the fiendish Red Dragon and taken prisoner.
At the Black Spider clan's base, Momiji is interrogated by Obaba for the Shrine Maiden's Eye of the Dragon. It is soon revealed that Momiji had managed to fuse the Dragons Eye into her soul, preventing Obaba from killing her. As events unfold, it is also revealed that Obaba is working for the Fiends' leader Ishtaros. Ishtaros eventually takes possession of the captive Momiji, after transforming Obaba into a fiend, in hopes that she may lure Ryu and kill him.
Later, during the battle between Ryu and Ishtaros at the Gates of Hell, Momiji watches in horror as Ryu is overwhelmed by Ishtaros and the Dark Dragonstones' power. Suddenly, the ghost of Kureha appears and draws out Momiji's soul. Together they release the Eye of the Dragon and imbue the Dragon Sword with its power, allowing it to become the True Dragon Sword. With it, Ryu is able to defeat Ishtaros.
As Ishtaros falls, Nicchae, the Greater Fiend of Destruction and Ishtaros's twin, appears and takes Momiji, Ishtaros' body and the eight Dark Dragonstones deeper into Hell in an attempt to reawaken the Vigoor Emperor. Nicchae's plan ends in failure, as the Dark Dragon consumes the Emperor and Ishtaros before bursting forth to threaten the world once again. Ryu defeats the Dark Dragon with the True Dragon Sword, and Momiji is finally rescued.
After the incident, Momiji is reunited with the children of the Hayabusa Village and mourns Kureha alongside the children. She makes a vow at Kureha's grave to become stronger so she can defend herself and the Hayabusa Village. She leaves Ryu a letter as she departs the village to train in her travels.
The Vampire WarEdit
After traveling and training, Momiji returns to the Hayabusa village and resumes her duties as Shrine Maiden. She and the villagers are very worried when Jo Hayabusa returns to the village wounded, but relieved when Ryu assures them Jo will recover. She then informs Ryu of the Black Spider Clan's presence in the Sky City Tokyo. Momiji is then tasked by Ryu to watch over the village.
Ninja Gaiden Sigma 2Edit
While Ryu is away at Tokyo, the Hayabusa village is invaded once again by the Black Spider clan. As Jo battles Genshin, Momiji rallies the Hayabusa ninjas to protect the rest of the villagers. Ryu later returns to the village and repels the invasion, killing almost all the invading Black Spider ninjas.
The next morning, Momiji surveys a destroyed part of the village and soon realizes that Sanji has been taken captive, prompting her to go rescue him. As she travels to Tokyo, she encounters one of the Tengu Brothers and soundly defeats him. This leads her to Sanji, who is being held prisoner by both brothers. After her victorious battle, she reassures the saddened Sanji that, until he becomes a master ninja, she will always look out for him.
As they return home, they are unknowingly saved by Muramasa, who kills a Black Spider Ninja who is about to shoot an arrow at them.
Ninja Gaiden 3: Razor's EdgeEdit
After Sanji finds Ryu unconscious outside and brings him to Momiji, she watches over him and helps him recover. During his journey to find his father in the shrine, she assists him in dealing with the Grip of Murder curse while helping him defeat the Black Spider Ninja Clan. Whenever the curse almost takes complete control over Ryu, Momiji uses her power to protect his mind and help him regain his senses. As they get near to the shrine, they are attacked by Obaba, but they manage to defeat her. Near the end of the battle, Momiji is knocked unconscious by Obaba, but Ryu manages to save her and brings her to the shrine to be taken care of by his father.
When Canna attacks Tokyo as the Goddess and Ryu begins to become overwhelmed by Fiends created by the LOA, Momiji and Jo arrive just in time to save him. She gives her master the Eye of the Dragon before he departs, leaving her and his father to fight off the surrounding foes.
Yaiba: Ninja Gaiden ZEdit
During the events Ninja Gaiden Z, Ryu catches word of a zombie epidemic that is sweeping across the world. Fearing what could come of this, Momiji accompanied Ryu on his mission to find the source and destroy it before all is lost. During a few days Ryu and Momiji tracked the cause down to a massive drill machine burrowing into a mountain in Russia.
There, Ryu encountered Yaiba, and engaged him in battle once more, ending with Ryu killing Yaiba for the second time with an Izuna Drop to the ground hundreds of meters below them. She and Ryu then find the source of the disaster; the formula used to create the zombies was coming from a long dead alien lifeform. As Ryu was preparing to destroy it, Yaiba appeared once again, seeking vengeance once more. Ryu grew exhausted from the battle, and appeared to be losing ground.
Just then Momiji threw the Dragon's Eye to Ryu, which awakened the Dragon Sword. The Dragon Ninja and the Ninja Slayer clashed, and triggered and explosion that rendered the ground unstable. Momiji was caught in the fall out, and Ryu swept in to save her. Ryu didn't care what Yaiba did to him, but he requested that he take the notebook he had found, and get it into the right people's hands, imploring that he find whatever shred of good that is left inside him. Yaiba however, tossed the book down into the abyss, and ripped out his core, severing Alarico del Gonzo's control over him, allowing Ryu to save Momiji from certain death. Ryu then thanked Yaiba, and returned Momiji home to the village to recover.
