Chino

is a member of the Chinoike clan.

Background
Chino is one of the surviving members of the Chinoike Clan, Chino was kidnapped by En Oyashiro, who had been collecting shinobi in possession of a kekkei genkai when she was very young to the point where she forgot her parents' faces. 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 En, Chino flees from him and sets out on her own path. Along the way, she meets Nowaki. The 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.

In the anime version, however, Chino met Nowaki (who is really Fūshin) when she fought and defeated him during her debut at the Coliseum. They bonded over their loneliness of being ostracised for their abilities and having no families. It was Chino's desire to find her clan at the Valley of Hell that prompted the escape of herself, Fūshin, Karyū, and two others. They formed the Lightning Group and began stealing money for the poor villages before being betrayed when Kirigakure began interfering. The group dissolved with Chino and Fūshin the only ones left. Upon reaching Valley of Hell and seeing it empty with evidence of her clan being dead, Chino vowed revenge for her clan's demise.

Personality
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 apologised to him on the villagers' behalf. She also offers him information on the group and the strange events surrounding the disappearances of Konohagakure, Kumogakure, and Kirigakure 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 herself feel more satisfied.

The only person Chino genuinely cares for is Nowaki, whom she is protective of and considers as a brother. She is even willing to give her life to save Nowaki when she fought Sasuke Uchiha 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 when she herself was unable to go out and create the bonds she so desperately desired despite never committing any crimes in the past. She also condemned him for always "having someone who loved him no matter how much he ignored it".

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 Nowaki to work for Kumogakure and Kirigakure to atone for their crimes.

Appearance
Chino has short, neck length, spiky white hair. Two thick strands reach onto her rosy cheeks. She has dark blue coloured eyes. However, they turn red when she activates her Ketsuryūgan. She also has small eyebrows. Chino 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.

Abilities
Chino is considered to be a very powerful kunoichi. Being a member of the Chinoike clan, she possesses the Ketsuryūgan, which allows her to manipulate blood and excel in genjutsu. Using Water Release, Chino can create defensive walls, blobs of water to attack with, and blow soap bubbles from her mouth. Chino is a sensor type, who can expel chakra into the ground, in-order to sense individuals. As such, she is considered a better sensor than Karin, and capable of sensing changes in chakra that Sasuke can't detect.

Sasuke Shinden: Book of Sunrise
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 Iō and is attacked. Chino intervenes and diffuses the situation, and apologises to Sasuke. She introduces Nowaki to him and explains what the Dark Thunder Group is and all the chaos it has caused the village, including the murder of Iō's daughter in a nearby village. Chino and Nowaki take him to Iō'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 Nowaki. She later alerts Sasuke that Iō killed its leader, Karyū, by setting the house on fire.

After Sasuke leaves to meet with Orochimaru, Chino and Nowaki also leave. He finds them on an isolated island with missing Kiri and Kumo shinobi, and when they cut themselves, he detects unusual chakra from them. Realising he has found out their scheme, they attack him. When Sasuke defeats Nowaki, Chino protects Nowaki and reveals herself as an enemy before attacking him with Ketsuryūgan genjutsu and fleeing.

Chino and Nowaki 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 Ketsuryūgan, but she grows angered at Sasuke for refusing to let her continue pursuing 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 saved 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 Nowaki 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. Although Chino and Nowaki are stunned, they agree to the proposition.

Anime
In the anime version, Chino does attack Sasuke at the command of Iō but quickly declines to continue upon seeing how strong he is. She sees Sasuke using his Sharingan to save those about to explode and realises he is a Uchiha. She explains to Sasuke that she and Nowaki are wandering shinobi who entertain for a living. As Sasuke leaves the Bamboo Village to learn more about Fūshin, Chino and Nowaki ask if they can come with him because they might be able to help him, which he relents. On the way, she asks Sasuke whether he plans to return to Konoha and restore the Uchiha clan.

Chino is surprised when they meet with Orochimaru but she gets into a fight with Karin, who is irritated at the latter for clinging to Sasuke. They travel via boat to the Coliseum to find En Oyashiro and witness how wealthy customers use their shinobi in competitions to win the losing shinobi. Chino is disturbed by this and tells Sasuke that if he doesn't help the poor and doesn't stop the rich, he is just as guilty, and she leaves with Nowaki. When more exploding humans appear, Chino is nearly killed but is saved by Sasuke, which surprises her. She and Nowaki later travel to the Land of Hot Water to find Fūshin but Chino complains they won't get to visit the hot springs. Five exploding humans appear in front of her and Nowaki but Sasuke saves them before going after someone who tried to attack him.

Sasuke arrives at the Valley of Hell, where he finds Chino waiting for him, and she reveals herself as the sole survivor of the Chinoike clan. She lashes out at Sasuke of how her clan struggled to survive after the Uchiha clan forced them to live there and is amused that Sasuke is interested in listening. She reveals her past of being kidnapped by Oyashiro, meeting with Fūshin and escaping with him, helping others before being betrayed, and vowing revenge upon finding no members of her clan survived.
