Female Giyu

Giyu Tomioka (冨とみ岡おか 義ぎ勇ゆう, Tomioka Giyū?) is a major supporting character of Demon Slayer: Kimetsu no Yaiba. She is a Demon Slayer of the Demon Slayer Corps and the current Water Hashira (水みず柱ばしら, Mizu Bashira?).

The Butterfly Mansion is the manor that the late Flower Hashira Kanae Kocho, Insect Hashira Shinobu Kocho, Tsuguko Kanao Tsuyuri, and assistants Aoi Kanzaki, Sumi Nakahara, Kiyo Terauchi, and Naho Takada live in. The manor is often used as a recovery base for injured Demon Slayers. All Hashira's including Giyu live in this mansion due to their higher up status, unlike the other slayers that live there, Hashira's rooms are customized to their liking to reflect on their powers, so Giyu's room is styled as a dark blue theme as for water.

Giyu is a young 19 year old woman of a lean, toned, yet somewhat voluptuous bodytype and pale complexion, who is almost always seen wearing a serious and emotionless expression. She has unruly black hair of uneven lengths that sticks up in tufts around her head, which she wears tied back in a low messy ponytail at the base of her neck. Her bangs fall over her eyes in an uneven fringe. Her eyes are sharp and moderately large, their irises a deep sapphire that fades to a lighter blue and their pupils a bluish-black, and are framed by thin eyebrows.

Giyu wears a dark cyan-tinted version of the standard Demon Slayer uniform with buttoned white leg-wrapped kyahan and a pair of white zōri with dark blue straps and tabi socks underneath being the same cyan color as her uniform. Over this, Giyu wears a haori that's split down the middle into two different patterns: the right one a solid dark red, and the left one geometrically patterned with rhombi of green, orange, and yellow. These haori were later noted to have belonged to her late older sister, Tsutako Tomioka, and her deceased friend Sabito.

Giyu always wears a stoic and unbothered expression on her face. However, she has a reserved personality and a very strong sense of justice with no tolerance towards those who don't know their own limitations and throw away their lives. Despite letting Nezuko Kamado live due to Tanjiro Kamado's persistence, she shows zero hesitation when killing other demons and has no respect or mercy towards them like most Demon Slayers. Even so, Giyu violated the Demon Slayer Corps' code of conduct without hesitation to protect Nezuko during Shinobu's attempt to kill her. This implies that she doesn't completely despise demons as some other Hashira do, and is willing to make an exception for a demon by letting them live if they don't kill and eat humans. This shows that she is more pragmatic in dealing with demons rather letting her hatred cloud her judgement.

Giyu appears to have a complex with what others think of her and is shocked when Shinobu Kocho claims she is hated by many. Besides that however, she doesn't seem to be hurt by Shinobu's other pokes, even ignoring her. Despite that, they are in fact friends with a good amount of history together. She is a woman of very few words and has trouble interacting with others, so she usually keeps himself at a distance. She even goes out of her way to tell Akaza that she hates talking, and wants to keep her name to herself, as she thinks names are not meant to be shared, especially to demons. Giyu also has a short temper that most likely developed due to Shinobu's constant tampering.

Beneath her seemingly unemotional and aloof attitude, Giyu suffers from an inferiority complex which she developed since her participation in Final Selection. This self-doubt in herself reached the point where she contemplates abandoning her position as the Water Hashira until Tanjiro helps her realize that instead of acting on her survivor's guilt, she should cherish her life and live on for the people who sacrificed their lives for her.

Despite her stoic nature, Giyu is shown to be protective and caring towards those she is close to and considers her friends. This is first shown when she puts her life on the line for Tanjiro and Nezuko by vowing to commit seppuku if the latter were ever to eat a human. Giyu has been shown to lose her composure and usual stoic demeanor when those she cares about are in danger, as seen when she is greatly angered by Akaza's attempt to kill Tanjiro and visibly shocked when she hears the news of Shinobu's death. This is further shown in the fact that she still wears half of Sabito, her late best friend's, and her older sister's haori as a memento of them. However, Giyu appears to be particular in who she shows emotions for, as she doesn't appear to react at all when informed of the passing of Genya Shinazugawa and Muichiro Tokito.

Indomitable Will: Giyu possesses an undaunted will and indomitable will, never giving up despite if she suffers from numerous injuries in a battle, she will not phased and continue to fight, unless she knows she'll lose.

Tactical Intellect: Giyu possessed great tactical intellect and sharp observation, always remaining calm, composed, and focused on analyzing the situation and reacting accordingly.

Immense Speed & Reflexes: Giyu possesses inhuman speed and reflexes, as shown when she took Nezuko away from Tanjiro's grasps at blinding speeds, which took him several seconds to register.

Immense Strength: As a Hashira, Giyu has honed her physical strength to beyond what is conceivable for human. Even since the first encounter with Tanjiro and Nezuko, she has displayed impressive feats of strength, such as swinging her blade with so much force that she caused an enormous gust of wind that knocked both Tanjiro and Nezuko back a far distance.

Master Swordsman: Being a Hashira of the Demon Slayer Corps, Giyu is one of the most powerful and skilled swordsman in the entire organization.

First Form: Water Surface Slash: Giyu generates enough momentum to create a powerful single concentrated slash.

Second Form: Water Wheel: Giyu leaps and vertically spins forward in the air while releasing a flowing attack in a circular motion.

Third Form: Flowing Dance: Giyu swings and bends their blade in a winding motion along with their body and dances in a flowing pattern, slicing everything in its path.

Fourth Form: Striking Tide: Giyu makes multiple consecutive slashes while twisting their body and sword in a flowing fashion to deliver multiple blows simultaneously.

Fifth Form: Blessed Rain After the Drought: Giyu changes the grip on their sword and decapitates the opponent in a single flowing strike that causes little to no pain. It is a “sword strike of kindness” used when the enemy willingly surrenders.

Sixth Form: Whirlpool: Giyu fiercely twists their upper and lower body, creating a whirlpool of air that cuts anything caught in it. Its effect and efficiently is enhanced underwater, where the user can draw water around their weapon to enhance their slashes.

Seventh Form: Drop Ripple Thrust: Giyu performs a fast and accurate stab, capable of reducing the impact of a moving target.

Eighth Form: Waterfall Basin: Giyu cuts the target vertically in a flowing motion which is most effective when they are falling downward.

Ninth Form: Splashing Water Flow: Giyu changes their footwork in a way that minimizes the landing time and surface needed when landing, allowing the user to move without limits. Ideal when fighting in a place with no solid foothold.

Tenth Form: Constant Flux: Giyu performs a continuous flowing attack which seemingly takes the form of a water dragon that increases in strength and power with each rotation due to momentum

Eleventh Form: Dead Calm: a form of Giyu's own personal creation, Giyu ceases all body movements and enters a state of complete tranquility, deflecting, blocking and cutting any incoming attacks with imperceptible speed with her blade. However, its effectiveness is limited as fast and numerous attacks can break through.

Standard Nichirin Katana: Giyu carries around a standard sized and shaped Nichirin katana with a black blade that has a deep blue outline. Her katana's tsuba is hexagonal in shape, with a bronze core and an overlapping red fuschia border. The handle is black and wrapped in white cords, and it ends with a fuschia kashira. As a Hashira, Giyu's blade has the words Destroyer of Demons, the katana is sheathed on the handle of the side of her haori.
