Buntan Kurosuki

is a kunoichi from Kirigakure.

Background
As a child, Buntan was raised solely by her mother, who often told her that she was worthless just like her father Raiga, who wasn't aware of Buntan's existence. At some point, she began a relationship with Shizuma Hoshigaki.

Personality
Like her allies, Buntan has a great hatred for the peaceful era for Kirigakure brought by the Sixth Mizukage, viewing it as an insult to their heritage as they calmly allow tourists to visit the village. Joining Shizuma Hoshigaki, she seeks to restore the "Bloody Mist" era and usurp Chōjūrō. Despite never meeting him, she is very fond of her father, and appears to hold a grudge against Naruto for killing him. She was originally in love with Shizuma and the feelings were seemingly reciprocated, leading Buntan to have unwavering loyalty to him.

In battle, she has great confidence in her abilities, viewing academy students like Boruto Uzumaki and Sarada Uchiha as being beneath her. Beneath her sadistic and arrogant demeanour, however, is a great amount of insecurity. Never knowing her father and being raised by a mother who showed no love, Buntan became desperate to prove her worth. As such, she feels that power obtained through a lineage like Kekkei Genkai is a cheat. On missions, she is cold and detached, believing that eliminating the enemies is the most efficient way to move unnoticed. Likewise, she prides herself as a very efficient interrogator, able to get anyone to talk. Despite this merciless nature, her love for her village's history has also led her to become well-versed in its ancient teachings, including for healing.

Buntan developed a heated rivalry with Sarada, stemming from their battle during the latter's field trip at Kirigakure, which resulted in Buntan's defeat and subsequent imprisonment. After Buntan and her allies were granted the chance to reduce their sentences by aiding Kagura and Team 7 with the Funato Clan's threat, Buntan resumed her rivalry with Sarada, both of them butting heads due to Buntan's reckless and bloodthirsty suggestions to eliminate their enemies, while Sarada urged them to remain cautious and out-of-sight. Following her time in prison, between being betrayed by Shizuma and spending time thinking about her mistakes, she came to regret her actions. Likewise, she lost all feelings for Shizuma and desires to kill him. She is also shown to be very loyal to her team-mates.

After Kagura saved her from Tenma Funato's attack, she developed a sense of appreciation and loyalty to him, as even though hearing that her prison sentence was reduced by a mere three years despite their efforts, she did not condone Hebiichigo's suggestion of killing Kagura to escape.

Appearance
Buntan is a young woman of average height and slender built with short and straight comb-backed blonde hair, blue-coloured eyes, a beauty-mark above the right of her upper-lip, and sharp teeth. She wears a red, pinstriped and sleeveless dress with a short skirt and leggings of the same design. She also dons a forehead protector and long wrist wraps, in addition to a sword hilt. After Shizuma's declaration of war, she dons a long-sleeved black jinbaori war coat with tan lining and grey hemming, draped over her shoulders in the style of a cloak.

Abilities
Buntan has demonstrated expertise in her movements, giving her characteristics of a trained shinobi or chūnin. She was skilled enough that Shizuma recruited her to be Kiba's wielder in his New Seven Ninja Swordsmen.

Ninjutsu
Buntan can use Lightning Release chakra to enhance the striking power of her attacks. When comparing her Lightning Release to Boruto's, she cited that hers was substantially stronger. Similar to her late father, Buntan is proficient in a variety of lighting-based techniques, including creating orbs, armour, and self-attacking creatures. She has also shown proficiency in Medical Ninjutsu, able to cure seasickness.

Kenjutsu
Buntan shows a particularly advanced skill in kenjutsu, able to calmly deflect a barrage of shuriken with her blade alone. In addition, her proficiency in it allows her to use it simultaneously alongside her Lightning Release. This allows her to quickly adjusted to using the Kiba, which also shows her to be an ambidextrous swordswoman. With the lightning-imbued properties of these twin blades, Buntan is able to greatly augment her attacks and likewise energise herself. She also excels in controlling the Kiba remotely, letting her attack from a distance and from multiple directions at once.

School Trip Arc
When Shizuma approached Kagura Karatachi, Buntan and her comrades accompanied him, where she protected Shizuma from Boruto's shuriken attacks. She later accompanied Shizuma and his group when Kagura took them to the shinobi swords' vault. Upon opening the container, Buntan took her father's swords Kiba, and used them on Puppets protecting the vault. Later, at their hideout, Buntan voiced to Shizuma on that now that they had their swords and Kagura, they could start their revolution.

Upon arriving at Memorial Park during the night, the group drew their swords in preparation to destroy the village's Memorial Stone. Before being able to, they were confronted by Boruto and Sarada, who were accompanied by Chōjūrō. Taking the opportunity to kill the Mizukage, Shizuma erected a mist barrier around the surrounding area. Ichirōta Oniyuzu used Shibuki on the ground, leading to Buntan and Sarada falling in a chasm. As Buntan began to attack and overwhelm Sarada, she made an effort to keep her distance so she wouldn't get caught in genjutsu, and attacked using her submerged fish. During the fight, Sarada managed to copy some of Buntan's techniques thus leading to a stalemate, until Buntan is placed in a genjutsu. Taking advantage of the hydrogen gas built up from the fish, Sarada used a Explosive Tag to ignite the cave, which caused an explosion that knocked out Buntan. She was soon after detained by Chōjūrō. After the group was defeated and rounded up, the event was covered by the Mizukage while Buntan and her team, minus Kagura, were sent to prison for rehabilitation.

Great Sea Battle of Kirigakure Arc
Sometime later, the swordsmen were moved to a new state-of-the-art prison. Shizuma planned an escape with Buntan, in which Hebiichigo and Kyohō were to be left behind, and Ichirōta and Hassaku would be scapegoats for a diversion. During the escape, Buntan was poisoned as part of Shizuma's plan and he abandoned her, using her as another distraction. As she, Hebiichigo, and Kyohō did not take part on the escape, their 10 years sentences remained unchanged.

After the Funato Clan broke out their leader from prison and took over all the neighbouring islands, Kagura recruited them three to deal with the situation, even allowing them access to the blades they wielded, though they were branded with cursed seals. She was amused to see Team 7. Upon arriving at Dotō Island to help the Konoha Team 5, Kagura decided that only Sarada and Mitsuki would go ahead to spy on the situation. The rest were later approached by a massive structure.

Realising it was a fortress ship, Kagura instructed Buntan to investigate it along Boruto and Kawaki. Discovering that Tenma Funato was in control of the fortress, Buntan explained who he was to Boruto and Kawaki. As they moved around, Buntan killed the Funato soldiers, drawing censure from Boruto. Concerned about Kawaki's seasickness messing up her opportunity to reduce her prison sentence, she cured it. Upon further investigation, they discovered a massive, long-range, scientific ninja tool Chakra Cannon.

After Boruto managed to radio Kagura and warned him about the Chakra Cannon, they learned that Sarada's group was on the fortress's path, requiring them to destroy the cannon themselves. They used Kagura's distraction to get close to the cannon, and were joined by Kagura's group. Before they could decide how to do it, they were attacked by Tenma. She warned the others about Kyohō's rage, and was protected by Kagura from one of Tenma's attacks, much to her surprise. Buntan held off Funato guards while Boruto used the maintenance cranes to aim the cannon at the fortress itself as it fired. They all escaped on a lifeboat and were rescued by Sarada's group. The swordsmen celebrated a reduced sentence with the mission's success, their presence surprising Team 5, before all heading back to Kirigakure.

The following morning, Taiki was discovered to have been murdered. Suspicion fell on Kyohō over his discovery cleaning blood off Kabutowari, and his recent rampage he had no memory of. Buntan believed him when he claimed innocence, and talked Hebiichigo down when tensions rose between her and Iwabee. She partnered up with Sarada searching the ship for the true culprit. A witness came forward with damning testimony, but Kawaki noticed inconsistencies in it, and suspicious of how fast word about the murder had spread, set up a trap by faking Kyohō's death. The real culprit, Kobasoza, was exposed, and Buntan wished to interrogate him to gain intel about the Funato Clan. Kobasoza chose to kill himself to destroy the ship's engine rather than betray the clan.

As the ship was stuck in the middle of the sea, they were found by master shipbuilder Kajiki. Unable to repair the ship at sea, he towed the ship to his port. There, Ninja Swordsmen joined Kagura to report to Kirigakure. On the phone, they learned that Chōjūrō had left the village to join the front-lines against the Funato Clan. Buntan was annoyed to hear they would be staying on the island longer.

Later, Buntan learned from Hebiichigo who spied on Kagura that their sentence was only reduced by 3 years. As Hebiichigo insisted they take advantage of their trust from Kagura to kill him and escape, Buntan remained opposed to the idea. While keeping quiet, Buntan was against it as she still felt indebted to Kagura for protecting her. Instead, she said such an act would only mean they'd be fugitives for the rest of their lives. Hebiichigo thought that Buntan got soft, Buntan told her to try escaping on her own if she was so determined.

Later that night, as Buntan wondered if Hebiichigo would go through with killing Kagura, the Funato Clan attacked the island. Kyohō was slow in alerting her of a leech getting on her, and she briefly struggled with it. By morning, the Funato attack had been repelled, and Buntan joined the investigation on it. Noticing Kagura's injury, she questioned Hebiichigo about it, but before she could answer, Kagura asked for their help.

After deciphering the coded message recovered from the Funato, they discovered the sea battle was a distraction so they could launch a sneak attack on Kirigakure while most of their forces were away. Kagura asked from the swordsmen's help, but they only agreed in exchange for a full pardon, which he agreed to personally negotiate with Chōjūrō. He took them to his childhood village, which was on the route the Funato forces were taking, so they could intercept them. She and Sarada ended up contributing to the plan together, noting that taking down two bridges would funnel the Funato into a ravine, putting them at a disadvantage. While fortifying the village's defences, the two began getting along better.

As preparations got along, she confronted Hebiichigo about her attempt to kill Kagura, and revealed Shizuma's betrayal at the prison to dissuade her from looking for him. Buntan explained her goal of tracking Shizuma down and killing him after being released, and pointed out that unlike Shizuma, Kagura didn't abandon them at any point. Kagura called for the swordsmen and removed their cursed seals in anticipation for battle, explaining that if he was killed, the seals would also kill them. Buntan teased Hebiichigo about how she almost got them killed. Word of Funato scouts reached the village, so they had to hide and pretend the village was normal. Butan was frustrated when learning Hebiichigo deserted the group, and volunteered to go retrieve her. Despite Sarada's apprehension, Kagura and Boruto trusted her and Kyohō to the task.
