🌊Tomioka Giyu

There's probably a typo in your search—the correct spelling is Giyu Tomioka (not "Tomioka Gib"). That's the Water Pillar from "Demon Slayer."

Personal data
Age: 21 years.
Height: 176 cm.
Weight: 69 kg.
Role: Water Pillar, one of the strongest fighters in the Demon Slayer Corps.

Appearance
A tall, slender, yet strong man with a slightly unkempt hairstyle: black hair of varying lengths, strands falling across his face. His dark blue eyes usually have a calm, seemingly distant look.

He wears the standard Demon Slayer uniform and his signature haori, which has two distinct halves: one is a solid dark red (in memory of his sister Tsutako), the other has a geometric pattern of diamonds in green, orange, and yellow (a nod to Sabito). The blade is engraved with the words "Destroy Demons."

Abilities and fighting style
Water Breathing. Giyu not only masters all ten canonical forms, but has also created his own—the 11th form, "Calm." It allows him to almost completely mute his own movements and perfectly deflect attacks: it's like the calm surface of water, concealing immense power.

Demon Slayer's Mark. During critical battles, the mark on his left cheek activates, dramatically increasing his speed, strength, and reflexes.
Tactical thinking. He doesn't waste energy, quickly assesses the situation, and acts with maximum effectiveness.
Endurance and willpower. Even with severe injuries (including the loss of an arm in the final battle), Giyu continued to fight to the end.

The name "Giyu" can be interpreted as "loyalty and courage", the surname "Tomioka" means "rich hill".
His favorite food is stewed salmon with daikon: it's one of the few things that can make him smile even a little.
His crow partner, Kanzaburo, is very old and often forgets orders, which quietly irritates Giyu.
He is afraid of dogs: he was bitten as a child, and the fear remained.

Date of birth: February 24th. Age: 18. Status: Demon Hunter, Insect Pillar in the Demon Slayer organization.

Height: 151 cm, weight: 37 kg.

Gender: female

Personality: In public, Shinobu always smiles and presents a friendly demeanor. However, this is a facade: inside, she harbors a deep hatred for demons due to a tragic past. She enjoys teasing others and can be a bit cruel at times. Shinobu is also not shy about using crude language. In combat with demons, she is ruthless: she can offer her opponents false hope of reform and then resort to torture. She is also capable of showing compassion, for example, towards Tanjiro Kamado and his sister Nezuko.

Past: Shinobu was the youngest child in the Kocho family. Her parents ran a pharmacy and lived happily with her and her older sister, Kanae, until they were killed by a demon. The Hashira, Gyomei Himejima, appeared and saved the girls by cutting off the demon's head. Afterward, the sisters joined the Demon Slayer organization to protect others. Later, Kanae was also killed by demons. Shinobu was unable to participate in Hashira training and instead trained Kanao Tsuyuri to avenge her sister. Shinobu also became a mentor to other students at the Butterfly Estate, where the wounded are treated and rehabilitated.

Full description
Status: Demon Hunter, Insect Pillar in the Demon Slayer organization.

Personal data:

Age: 18 years.
Date of birth: February 24.
Height: 151 cm, weight: 37 kg.
Gender: female.
Appearance: A petite girl with pale skin. She has large, pupil-less eyes with a gradient purple iris, reminiscent of an insect's. Her shoulder-length hair smoothly transitions from black to dark purple; it is usually held back in a yakai-maki style with a white and purple butterfly clip. She wears the standard hunter uniform: a dark purple jacket, hakama pants tucked into a butterfly-printed fabric around the legs, a white haori with a butterfly wing pattern (a haori left over from her older sister), and white sandals with purple straps.

Personality: In public, Shinobu always smiles and presents a friendly demeanor. However, this is a facade: inside, she harbors a deep hatred for demons due to a tragic past. She enjoys teasing others and can be a bit cruel at times. Shinobu is also not shy about using crude language. In combat with demons, she is ruthless: she can offer her opponents false hope of reform and then resort to torture. She is also capable of showing compassion, for example, towards Tanjiro Kamado and his sister Nezuko.

The Hashira, Gyomei Himejima, appeared and saved the girls by cutting off the demon's head. Afterward, the sisters joined the Demon Slayer organization to protect others. Later, Kanae was also killed by demons. Shinobu was unable to participate in Hashira training and instead trained Kanao Tsuyuri to take revenge on her.

Agility and Speed: Shinobu is incredibly agile, allowing her to easily dodge attacks and maneuver in combat.
Endurance: Through rigorous training, she has achieved a high level of endurance.

Medical and pharmaceutical knowledge: this is a key compensation for her relatively weak physical strength (she even noted that she cannot decapitate a demon, unlike other Hashira). Shinobu masterfully creates various poisons, can saturate her body with poison without causing harm, and has the ability to counter demon poisons.
Additionally, she developed a sign language system with Kanao to quickly convey important information.

Fun fact: The name "Shinobu" is old-fashioned and traditionally refers to female ninjas, and can also be translated as "dance." The family name "Kocho" means "butterfly."
