Nakoruru/Story

Samurai Shodown I, III & IV
At 15, she and Rimururu are playing in the forest when Mamahaha flies in holding her father's sword. Sensing her father was in danger, she apologized to Rimururu and leaves. Upon reaching Hinowa, Nakoruru tells Gaoh that his war is hurting the planet. Gaoh proclaims he will build a new country and will destroy any who would stand in his way. At his defeat, Kamui appears before her, asking Nakoruru to follow her father's footsteps as he was killed. Nakoruru asks what would happen if she declined and is told another maiden would be asked to be the successor. Not wanting Rimururu to be put at risk, Nakoruru accepts to become the new Kamui warrior of Kamui Kotan.

Samurai Shodown II
She continues to fulfill this role throughout the series protecting nature and defeating villains often alongside Haohmaru. However, after overthrowing Mizuki Rashojin, she sacrifices herself to restore nature's balance and becomes one with the spirit of Nature.

Samurai Shodown 64
In Samurai Shodown 64, her apparent death is retconned. Instead of sacrificing herself, she slept within Kamui Kotan's forests and was protected by the spirits of nature. At nature's beckoning, she awakens to fight the disturbing presence caused by Yuga the Destroyer. Sometime after Yuga's second defeat, she eventually returns to her slumber.

Samurai Shodown: Warriors Rage
Later in Warriors Rage, she transcends even further and melds her soul with Gaia to become a Divine Spirit in nature's service. As one of the "Maidens of Light", she travels across space and time to prevent the disasters of the world from occurring. However, she is stopped in her quest by a magical spell cast by Jigen Taishi in Ritenkyo. This leaves Nakoruru unable to assume her original form, and she can only battle evil through the strength of her fellow forest sprits. Weakened, she knows she must stop Oboro's evil plan, but cannot without the Maiden of Light Rimururu, who has been sealed by Oboro. Nakoruru informs Haohmaru of the threat and sets out on a quest to free her sister and together combine their powers to defeat evil.

Samurai Shodown Sen
In Sen, she follows the runaway Rimururu, hoping to protect her younger sister from the danger that she sensed. She also left her home to tell Rimururu the reason why she is in her current predicament.

Nakoruru ADV
In this game, Nakoruru is living peacefully at her home as the village's priestess. At the behest of the village's elder, she adopts a protege named Mikato and teaches the young girl about Kamui and her society's culture. However, Nakoruru remains distant due to her other half, Rera, who constantly warns her about an incoming evil. Wanting to continue her life of serenity, Nakoruru doesn't talk about this to anyone. She is also afraid of losing her own identity if she accepts Rera completely.

When Mikato discovers the truth about her reluctant nature, the priestess has already lost her powers due to her selfish nature. Despite this, she takes action once her home is attacked by demons and sets out alone to somehow deal with the threat peacefully. Eventually, Nakoruru accepts Rera and fights Mizuki. Unfortunately, while protecting Mikato from being hurt, she is badly injured. She succeeds in dealing a mighty blow against Mizuki but succumbs to her wounds and dies. Mikato, who was destined to carry out the priestess' prophecy, uses Nakoruru's sword to avenge her. It's implied that Nakoruru is happily reunited with Yantamu in the afterlife.

The King of Fighters XIV
Sometime after her ascension as a spirit of Nature, Nakoruru sensed terrible malice coming from a crack in spacetime. To prevent the disaster of its potential release and to find its source, Nakoruru traveled to the modern times (where The King of Fighters universe and story takes place) and enters the tournament in The King of Fighters XIV with Mui Mui and Love Heart.

After Verse's defeat, Nakoruru senses that it may one day be revived. She decides that she and her comrades should stay in this universe, declaring her wishes to visit the present-day Hokkaido and China.
