Role in Games[]

Samurai Warriors[]

In Samurai Warriors 3, Aya is alongside her brother and son in the Uesugi army as a unique non-playable character. She participates in most of the Uesugi campaigns as a support unit and occasionally appears as a representative of her clan in other characters' scenarios. To uphold the morality of the army, she fights to inspire Kanetsugu and the men. She is the one who is responsible for selecting Kanetsugu to enter the Uesugi ranks, choosing him specifically for his virtuous nature. There is a mission to rescue her from the central garrison in Tedorigawa from a fire attack and an ambush led by Saizo Kani. She and Masanori may be saved by Takamaru early in the Murasame Mode.

Her story in the Sengoku Musou 3: Moushouden expansion has her mainly support her younger brother's campaigns, occasionally choosing to personally deal with his opponents herself to test their integrity. She joins her brother in his campaigns through Kantō, Kawanakajima, and Suruga-Sagami. By the end of the third battle, Kenshin's actions have brought peace to the Kantō region. However, Nobunaga threatens their truce by attempting to invade east. Since he is closest to the conqueror, Kenshin volunteers to face him and usher in the Uesugi's virtue to the west. Prior to their clash at Tedorigawa, Aya decides to enlist the young talent, Kanetsugu, and instructs him to believe in the Uesugi's principles during combat. She makes it her responsibility to keep both Kenshin and Kanetsugu safe in their campaign to destroy the Demon King.

Though successful in driving Nobunaga back, Kenshin dies soon after the conflict. His death sparks internal rebellion between his two adopted sons, Kagekatsu and Kagetora. Although Kagekatsu is Aya's biological son, she supports Kagetora and opposes her son and Kanetsugu. Through her actions, she believes she is testing Kanetsugu's resolve to carry on with Kenshin's will. During the battle, she protects Kagetora while waiting for their Hōjō reinforcements led by Kai and Kotarō. Surprisingly, the Takeda take note of the battle, seeking to send Yukimura and Kunoichi in Kagekatsu's support. In order to capitalize on the rebellion, Nobunaga and other Oda generals enter the conflict to cut down either heir. Once the secondary enemies fall, Kanetsugu spurs Kagekatsu's men to charge in Kenshin's name. To Aya, however, he declares himself to be insufficient to carry on Kenshin's drive to wage war, but he believes that love will one day realize justice the world needs. Feeling inept for straying from Kenshin's image, Kanetsugu believes he should die as repentance. Aya scolds him, for she is actually impressed by his new motivation to carry on Kenshin's sense of virtue through different means. She agrees to watch over his decisions for the Uesugi's new future.

Sengoku Musou 3: Empires has Aya continue to support her brother in his story route. While occasionally reminding him of his duties to those in need, she is understandably sympathetic when he briefly loses his composure due to Shingen's death.

Aya resumes her previous actions in Samurai Warriors 4 by supporting the Uesugi army in most of their campaigns. She is Kagekatsu and Kanetsugu's stern instructor for learning Kenshin's values and the babying foster mother for Kagetora. Prior to the Uesugi civil conflict, she voluntarily joins Kagetora's camp. The brothers instinctively understand that her gesture is for comfort of his impending defeat rather than support for Kagetora's cause. Aya's last appearance in Story Mode is at Hasedō.

Warriors Orochi[]

In Warriors Orochi 3, Aya joins her brother and Shingen's attack on Da Ji at Shizugatake. Once the coalition bests the two veteran generals in combat, Aya voluntarily joins the coalition. She reminds them that though the Uesugi and Takeda continue to refuse obedience to Da Ji due to the chaos it would spread with the other warlords, she acts as a representative of their changed opinion regarding their opponents. She later helps the attack at Fan Castle to oppose Wei army led by Cao Cao and investigates the ruckus at Luo Castle, eventually leading to Okuni's cooperation. She also supporting Shu-Tokugawa led by Liu Bei at Chengdu. She learns with Liu Bei about a good things of benevolence.

In one of the downloadable scenarios, "Warriors of Purity", Aya commands a team of white-hooded warriors in destroying evil. She considers her brother and Xu Huang her "Kenshins" and eventually considers herself a "Kenshin" because of her white hood. In another stage, "True Love", Aya helps the mystics Nuwa and Nezha see the good qualities of human love in all its forms.

A clone of her, Kanetsugu and Shingen later attack the Uesugi and Wu forces at Hefei in Ultimate. Although, she and the real Kanetsugu and Shingen appear in the battle, a confused Yukimura, Kunoichi and Kenshin still attack and defeat the trio. After the battle Shennong clears up the misunderstanding, explaining of Tamamo's plot to pit the humans against each other.

During 4, Aya retains her spot as a member of the Uesugi army, which has allied with Liu Bei against Nobunaga. While the main bulk of the Rebel forces are busy rescuing Shingen and the rest of the Takeda forces, Aya and Kagekatsu's outposts are attacked and nearly overrun at Xu Province, but Yukimura and Kenshin's forces are able to rendezvous with Aya's forces and rescue the pair.

Aya later joins Sun Quan in fighting his family at Guandu.

Pokémon Conquest[]

Aya continues to support her younger brother in Pokémon Conquest. If the player chooses to approach Kenshin's kingdom of Illusio, she leads Kenshin's forces to attack one of the protagonist's castles. She demands to test the hero's love for their Pokémon and resolve to unify the land. Upon her defeat, Aya deems that they are worthy opponents for Kenshin and respectfully withdraws. Her last act in the game's main story is defending Illusio alongside her brother.

Nobunaga's Ambition[]

Nobunaga no Yabou 201X features the Uesugi civil conflict for succession as a limited-time event. The SLO agents have already sealed the demon portal, but Director Isurugi informs them that a portal still remains in the vicinity. When they return to medieval Echigo to investigate, they have somehow slipped into a UMA time loop and see their past selves talking with Kanetsugu.

Sentō-In conceals them from their past selves to avoid disrupting the timeline and guides them to a quiet room within Kasugayama Castle. Within it is Kenshin, Shingen, and Ujiyasu, all of whom were supposed to be dead. Sentō-In calms the panicking Matsuri and requests the SLO agents to help her keep the group hidden and dispatch the UMA threat. When her younger brother is sheepish to reveal the manner how he died to the other daimyou, an exasperated Sentō-In states it with brutal honesty.

Nobunyaga no Yabou highlights her kitty counterpart during the Dokii! Himedarake no Neko Senki scenario. Aya-nyan worries that her younger brother's conflicts with the Uesugi governor and Mikeda may lead him to an early grave. Therefore she asks her husband to speak on Kagetora's behalf. Since her husband carries out her wish, a civil conflict within Echigo is avoided. Aya-nyan is later seen lamenting the civil conflict between her brother's sons. She believes Kagetora has lost sight of the Uesugi's integrity and chooses to leave him. The narrative remarks that her departure opened the gates for Kagekyatsu's forces and Kagedora's forces soon fall.

Guruguru Dungeon Nobunyaga has Aya-nyan appear in the Uesugi legacy event. She greets the protagonist into the Uesugi and privately confides her fears that the brothers will someday quarrel. When her predictions become reality, Aya-nyan and Kagekyatsu implore the protagonist to negotiate peace with Kagedora. Aya-nyan accompanies him/her to Kasugayama Castle. When he/she is turned away, Aya-nyan volunteers to stay within the castle and continue to convince Kagedora to surrender. Aggressions persists even with her presence in the castle.

Character Information[]

Samurai Warriors 3 artwork.


Sophisticated, calm, and reserved, Aya places no importance on material gain. Instead, she finds abstract matters to hold utmost priority for her clan. She is aware that constantly waging war without morals will only lead to further conflicts for the world. Therefore, Aya stresses the importance of virtue to correct the world's flaws. Believing that justice, honor, and love should be kept at any cost, she will feel no hesitation for removing any obstacle that deters from these beliefs. If needed, she would accept the deaths of her brother or herself for the sake of restoring world order. Often choosing to act as support for the prominent male figures of her clan, Aya is stern on reminding them and the Uesugi generals to never forget their true purpose for fighting. She frequently uses the Buddhist four character idiom, Haja Kenshō (破邪顕正), in the Japanese script. It summarizes the objectives she wants her family to follow: "tear down depravity so justice can be realized".

Kenshin refers to her as a goddess and respectfully addresses her as "Elder sister". He remains faithful to her wishes and frets over her well being at all times. Aya dotes on her younger brother's eccentric traits, as well as his desire to wage "pure war", calling him "cute" or "adorable". She watches over him affectionately, occasionally known to lightly tease her younger brother. Even so, she prioritizes her strong belief for universal love before family ties, hiring Kanetsugu to spread her resolute beliefs when she isn't capable of doing it herself. She is content to watch over both men as an endearing presence for them. During the fourth title, she adopts a maternal role for both her sons.

If Kanetsugu fails to meet her expectations, however, Aya can become the stringent teacher to lecture him back in order. When Kanetsugu brashly jumps to conclusions that stray from the Uesugi's integrity, she chides him for foolishly lacking dignity (うるたえ者). Her darker traits are exaggerated for humorous effect in the spin-off titles, practically to the point in which she is Kanetsugu's dominatrix. She and the playable Kojūrō mask their mutual loathing for one another through a thin guise of pleasantries. Aya particularly insults his glasses and his presumptuousness. She shares special conversations with Lianshi and Zhong Hui in her Warriors Orochi appearance, the latter being on the receiving end of her strict punishments due to his haughty attitude.

Out of comic relief, Aya's cooking is also said to be quite dreadful, but enough to have people (such as Kenshin) forcefully praise it out of fear of her strict nature.

Character Symbolism[]

She is symbolized by the characters "virtuous" (淑) and "holy" (聖) for her Samurai Warriors appearance.

All of Aya's weapon types are known for being a cultural icon for their white feathers. Her Normal weapon is named after a white swan. Her Power weapon embodies a Japanese ibis while her Speed types embody a grey heron. In the case of the first two birds, they represent a removal from worldly desires and purity. The ibis is especially known for its rarity; a handful of those remaining are captured and raised to escape the clutches of extinction. A grey heron is known as a bird of winter in Japan, known to bravely face the frigid temperatures by puffing up its feathers. The bird is likely meant to tie in with Echigo, known for having freezing winters throughout Japan's history.

Her third weapon in Chronicles 3 takes its namesake from the fabled peaches of immortality. In Chinese culture, the fruit is considered a symbol of longevity and often associated with Xi Wangmu. It shares a similar meaning in Japan with the added distinction of repelling evil. During Izanagi's flight from the underworld, Izanagi ran to a nearby peach tree and tossed three peaches at his pursuers to escape safely.

Her first Unique weapon is an alternate name for Tenrin Jyooh, a term used in Indian religions for an idealistic ruler. According to ancient Indian beliefs, the term means to bring order to the world by using military force. Within Buddhist texts, Tenrin Jyooh is usually called a saintly king who is destined to one day usher in a new age of prosperity for humanity. He is said to appear once humanity regains their lost virtue and is destined to rule for the 8,000 years of regained peace. When he is gone, the world is destined to once again plunge itself back to darkness. The ring mentioned within the term can either refer to the sun, a wheel-like weapon known as the chakram, or a mandara. It symbolizes Tenrin Jyooh's laws and his right to create and dictate them without question.

Kariteimo appears in the name for Aya's secondary Unique weapon. She is known as Hariti in Sanskrit and is known as a Yaksha goddess. Kariteimo is known to be one of Bishamonten's wives who gave birth to 500 -sometimes said as 1,000 or 10,000- people. She loved all of her children, but she killed several other children in order to properly feed hers. Shaka one day took away her youngest child, Purinyanka, causing her to forlornly leave to search for her boy. Realizing the suffering her actions had caused for other mothers, she converted to Buddhism. She is known as a goddess who blesses the safe deliveries of children, granting them prosperity and good fortune.

Her heirloom is a historical document for the Uesugi family history. It records their family history starting from the Kamakura period to the Edo period, including genealogy and details of the Yamauchi-Uesugi and Echigo-Nagao clans. It is within this record that many tales of Kenshin and his family are proposed yet remain disputed by modern historians for their accuracy. It is currently stored within the Yonezawa City Uesugi Museum.

During the Uesugi story in the fourth Samurai Warriors title, Aya gives Kagetora a snack called sasa-dango. It's a confectionery made by being wrapped and steamed in sasa bamboo leaves. Sasa-dango was known as a healthier counterpart to the sweeter dango variations from the capital during the game's setting, since it was often filled with the same ingredients for riceballs (onigiri). They could be wrapped in kinpira to aid preservation, giving it a sour or bitter taste. The origins for the snacks are unknown, but one myth suggests that it was first created by Kenshin or the Uesugi retainers as portable war rations that helped them brave the harsh winters of Echigo.

Historical Information[]

Sentō-In was Nagao Tamekage's second eldest daughter. She was said to either come from the same mother as Kenshin or was his older half-sister. Though better known under her Buddhist name, it was said that her given name was Ayahime or Okame no Kata.

She was engaged to Nagao Masakage sometime during 1537, and they had two sons and two daughters together. Their eldest son died at the young age of 10 so their second eldest son, Kagekatsu, was adopted into the Uesugi family under Kenshin. Their daughters are also said to have been adopted into the Uesugi and supposedly became the wives of their loyal vassals. Sentō-In moved to Kasugayama Castle with her son in 1564. She was fabled to have recognized Naoe Kanetsugu's talents and recommended him to serve Kagekatsu. It was rumored that Kanetsugu tried his best to care for her in gratitude.

When the civil dispute between Kagekatsu and Kagetora took place after Kenshin's death, Sentō-In tried to protect Kagetora's heir after the death of her eldest daughter (Kagetora's wife). Although she was with Kagetora, she returned to Kikuhime and Osen no Kata's care. She died at Yonezawa Castle and was enshrined at Risen-ji. She was given the Buddhist name, Sentō-In. As for why she was named as such, the reasons are still debated even to this day.
