Chizuru Kagura/Story

Past
Chizuru is the younger of the twin heiresses of the Yata clan, the other being her older twin sister, Maki Kagura. As the heiress of the Yata, she was raised as a priestess and was given the duty of keeping the diligent seal on Orochi intact. One night, Goenitz visited their home with intentions to destroy the seal. Maki confronts him, but since the power of their clan can not fight the Orochi without the help of the other two clans and Goenitz's strength as one of the Heavenly Kings was too great, she loses and is mortally wounded. Goenitz destroys the seal and leaves with the satisfaction of a weak but released Orochi. Before her death, Maki passes on the responsibilities of the seal to Chizuru, begging her to join the three clans together once again to defeat Orochi.

The King of Fighters '96
Ten years afterwards, Chizuru became a very successful and prestigious business woman under the family name Kagura. She secretly kept track with the King of Fighters tournaments since it began with Geese Howard, and hosts the tournament in 1996 in hopes of entreating the two other heirs, Kyo Kusanagi and Iori Yagami, to help her replace the broken seal.

After the tournament, Chizuru appeared before Kyo and Iori, revealing that she was the one hosting this year's tournament, in an attempt to lure out the two men to fight the real threat; the coming return of Orochi. Before she could explain any further, Goenitz appears and destroys the stadium where the finals were being hosted. He reveals himself as the leader of the Hakkeshu, and that Mature and Vice were keeping an eye on Iori Yagami, since he is a descendent of Orochi. Seeing an opportunity to finally end all three heirs at once, Goenitz attacks the trio, but is ultimately defeated. In the final events of the tournament, he is defeated by Kyo with the help of Iori and Chizuru. Humiliated, Goenitz saves face and apparently took his own life in the aftermath of the tournament by cutting his body on his own wind.

Chizuru explains that since Orochi is on the verge of resurrecting, the three should form up together like their ancestors did nearly 1800 years ago. However, Kyo and Iori despised the idea of working together, and rejected her request.

The King of Fighters '97
Chizuru publicly announces that she will be participating in KOF '97 to see how she stacks up with other fighters. In reality, she is coming in order to convince Kyo and Iori to work together again. She decides to team up with King and Mai Shiranui to form the Women Fighters Team.

During the finals of the '97 tournament, Kyo confronts Iori. However, Iori suddenly enters the Riot of Blood state. At the same time, Leona falls to the Riot of Blood state, revealing that she is also a descendent of Orochi. Kyo, Ralf and Clark fight to snaps them out of the state. Realizing the situation, Kyo, Iori, and Chizuru come together and form the Three Sacred Treasures Team to stop the Heavenly Kings from reviving Orochi.

Kyo, Iori, and Chizuru confronts the remaining Heavenly Kings of Orochi, Yashiro Nanakase, Shermie, and Chris. The Hakkesshu also mention the plan to sacrifice Kyo's girlfriend Yuki in order to revive Orochi. Fueled by these turn of events, Kyo, Iori, and Chizuru fights an emotional and heroic battle against the remaining Heavenly Kings. Their battle ends up reviving Orochi, but not at full power. In order to him to reach full power, both Yashiro and Shermie commit suicide in order to transfer their remaining energy into Chris and because of this, Orochi is able to return to the world while using Chris' body as the host, and attempts to destroy the three clans at once. As was done in the legends of their clans, the trio successfully defeat him.

In a last-ditch effort, Orochi causes Iori to enter the Riot of the Blood state, expecting him to turn on Kyo and Chizuru. Instead, Iori snaps out of his control and snares Orochi by the neck. Kyo suddenly gets a vision by various members of the Yasakani clan, explaining the circumstances behind Iori's past and his connection to Orochi. Kyo obliged his rival by crippling the great demon with one last deathblow, allowing Chizuru to reseal Orochi.

The King of Fighters 2003
She hosts another King of Fighters tournament in 2003 with intentions similar to her previous attempt. During the tournament, however, it is revealed that Chizuru was under mind-control by a mysterious puppeteer, Botan, a member from Those From the Past.

Ironically, she ends up using the power of the Yata Mirror for the benefit of the very force she was trying to combat, and fights alongside an illusion of her sister Maki as one of the game's sub-bosses. Eventually, she breaks free from Botan's control and tries to restore the seal of Orochi, but Ash Crimson steals her powers before she can. She survives the attack, but can no longer participate in fights.

The King of Fighters XI
Prior to the eleventh tournament, Chizuru asks Kyo's self-proclaimed disciple, Shingo Yabuki, to fill her spot of the Sacred Treasures Team.

The King of Fighters XIII
Before the thirteenth tournament, Iori pays a visit to Chizuru to see if she needs her treasure to use her power. Realizing that his predictions are true, she presents Iori with the prospect of ridding the Orochi curse from his bloodline since he is no longer hindered by his treasure.

She keeps in touch with current events and Ash's movements by talking with Benimaru Nikaido. Her powers return when Ash disappears in The King of Fighters XIII.

The King of Fighters XIV
At the end of The King of Fighters XIV tournament, sensing the presence of Orochi after Verse's defeat, Chizuru contacts Kyo to head west to Hungary and there, together with Iori, the trio deal with what believed to be a weakened Orochi.

The King of Fighters XV
For The King of Fighters XV, Chizuru reenters the tournament for the first time since 2003 alongside Kyo and Iori to form the Sacred Treasures Team.
