Buntan Kurosuki

is a kunoichi from Kirigakure.

Background
As a child, Buntan was raised solely by her mother, who reminded her she was worthless just like her father Raiga, who wasn't aware of Buntan's existence.

Personality
Like her allies, Buntan has a great hatred for the peaceful era of 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 seemingly has a romantic fondness of Shizuma, seen from her snuggling against him. In battle, she has great confidence in her abilities, viewing academy students like Boruto Uzumaki and Sarada Uchiha as being beneath her. Beneath sadistic and arrogant demeanour however is great 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 lineage like Kekkei Genkai is a cheat.

Appearance
Buntan is a young woman of average height and slender built with short and straight comb-backed blond, blue-coloured eyes 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.

Nature Transformation
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.

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.

Field 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. After acquiring the blades, with Buntan taking Kiba, Shizuma voiced more of his plans, noting that he had allies within the ranks of the Water Daimyō who agree with Shizuma's goal of restoring the "Bloody Mist" era. He also intended to place Kagura as the new Mizukage, continuing the vicious reign of the Fourth Mizukage.

Their first act of revolution was to destroy the Kirigakure Memorial Stone. Before they could destroy it, they were confronted by Boruto and Sarada, along with Chōjūrō. Shizuma was glad at this development and cut off the area with his Crimson Mist Barrier Technique to begin the battle. Ichirōta Oniyuzu used Shibuki to cause an explosion on the ground, making Sarada fall into a chasm to face Buntan. Buntan was in control for much of the fight, making an effort to fight from a distance so Sarada could not unleash any genjutsu on her with the Sharingan, and limiting Sarada's mobility by having a Lightning Fish in the water. In the end, Sarada was able to get close enough to copy some of her Lightning Release, and managed to place her under genjutsu, as well as take advantage of her lightning fish, which caused a buildup of hydrogen gas. Buntan was knocked out when Sarada ignited it, which caused a great explosion.
