Chino is one of the surviving members of the Chinoike Clan, which originated from the Land of Lightning. During her childhood, her clan became recognized and feared for their Kerryūgan. Soon after, the clan was driven out of the nation and into the Land of Hot Water by the Uchiha Clan under orders by the daimyo of the Land of Lightning. After settling into the Valley of Hell, Chino was kidnapped by Oyashiro En, who had been collection shinobi in possession of a kekkei genkai. He raised her into a merciless and vengeful shinobi, giving her the task of capturing other kekkei genkai users and eliminating threats.
Upon learning her entire clan had been wiped out by enemies and angered by the mistreatment from Oyashiro, Chino flees from him and sets out on her own path. along the war, she meets Nawaki, whom she learns is also a survivor of the Chinoike clan. They two then band together and travel together, robbing rich people of their goods for themselves to survive. However, Chino was not able to let go of her hatred towards the villages, which she blames for allowing her clan to perish.
At first glance, Chino appears childlike, sweet, and timid. When she first meets Sasuke, she quickly defends him from being attacked by villagers who mistook him as a member of the Dark Thunder Group, and apologized to him on the villagers' behalf. She also offers him information on the group and the strange events surrounding the disappearances of Konoha, Kumo, and Kiri shinobi. However, behind this façade, she is actually cold-hearted, manipulative, and vengeful. Due to being raised as a weapon and blaming most of the Five Great Nations for her clan's demise, Chino is determined to achieve revenge by kidnapping many of the village's shinobi to use them against each other, and is willing to kill them to make her feel more satisfied.
The only person Chino genuinely cares for her Nawaki, whom she is protective of and considers as a little brother. she is even willing to give her life to save Nawaki when she fought Sasuke in the Valley of Hell. Although she is initially kind to Sasuke when they first met, she actually despises him due to his clan being partially responsible for her clan being exiled. She also condemns him as a hypocrite; Sasuke was once someone consumed with hatred and plotted to destroy Konoha for what it did to his clan, and now he is trying to stop her from doing the same thing to the nations.
After her battle with Sasuke, Chino realises the error in her actions. Like him beforehand, she allowed her emotions to cloud her judgment and she was inadvertently trying to destroy the peace she desired for. She was left guilt-ridden and was ready to face the consequences of her actions, but was surprised and happy when she learned Sasuke put in a good word for her and Nawaki to work for Kumogakure and Kirigakure to atone for their crimes.
Chino has long brown hair and light colored eyes. However, they turn red when she activates her Kerryugan. She is small for her age, as Sasuke pointed out that she looked ten-years-old when he first met her and was surprised when she told him that she was in fact much older than him.
As a member of the Chinoike clan, Chino possesses an affinity for Lava Release and is considered to be a very powerful shinobi.
Chino is able to use the Kerrygan. with this, she has the ability to manipulate blood and excel in genjutsu. Once it is activated, her eyes turn blood-red.
When Sasuke arrives at a bamboo village in the Land of Hot Water, he is mistaken as a member of the Dark Thunder Group by a villager named Io and is attacked. Chino intervenes and diffuses the situation, and apologizes to Sasuke. She introduces Nawaki to him and explains what the Dark Thunder Group is and all the chaos it has caused the village, including the murder of Io's daughter in a nearby village. Chino and Nawaki take him to Io's daughter's village to investigate, and she asks him questions about the Uchiha Clan and his indecisiveness of living in Konoha. When the group attacks once again, Chino fights back with taijutsu and is able to defend herself and Nawaki. She later alerts Sasuke that Io killed its leader, Karyu by setting the house on fire.
After Sasuke leaves to meet with Orochimaru, Chino and Nawaki also leave. He finds them on an isolated island with missing Kiri shinobi, and when they cut themselves, he detects usual chakra from them. Realizing he has found out their scheme, they attack him. When Sasuke defeats Nawaki, Chino protects Nawaki and reveals herself as an enemy before attacking him with Kerryugan genjutsu and fleeing.
Chino and Nawaki find refuge in the Valley of Hell but they are found by Sasuke shortly after. Chino challenges him to a battle, which she is confident she will win. She initially overpowers Sasuke with her Kerrygan but she grows angered at Sasuke for refusing to let her continue attacking the villages for revenge. She berates him for trying to stop her when he once did the same things, and is disillusioned why he changed his mind. Hearing Sasuke reply that his friends saves him from darkness and he fights for peace causes Chino to question her own resolve. Sasuke uses genjutsu to ware her down but he assures her that he will not kill her and she accordingly surrenders.
Chino explains to Sasuke about her hatred for the villages after they used and destroyed her clan, and that she fears peace can never be maintained. Sasuke promises her that he will always protect the peace she longs for, and she and Nawaki agree to be taken to prison to face judgement for their crimes. The Sixth Hokage visits with them and tells them that Kumogakure and Kirigakure are offering the two to work for them in exchange for their freedom. Chino and Nawaki are stunned by agree.
- "Chino" (血之) literally means "of blood".
- It is unknown if Chino is her real name due to it being similar to her clan's name. It is possible it was a name given to her after she was abducted by Oyashiro.
