Kiriya Ubuyashiki ( (うぶ) () (しき) () () () Ubuyashiki Kiriya?) is the only son and middle child of Kagaya Ubuyashiki and the head of the Ubuyashiki Household. After his father's passing, he leads the Demon Slayer Corps as the 98th and final leader.

Appearance[]

Kiriya has light, pale skin and large eyes. He has the same hairstyle as the rest of his siblings; a blunt bob with a fringe covering his eyebrows, colored black. As he was raised as a girl, he takes on a more feminine appearance during his first appearance.

During the Final Selection test, Kiriya wears a purple uchikake kimono with patterned flowers and a green obi, supported with a white obiage and indigo obijime along with a white juban under everything. His head is adorned with a wisteria headpiece.

Later on in the manga, after he becomes the leader of the Demon Slayer Corps, he wears a black kimono with a long white haori that's reminiscent of his father.

Personality[]

During his first appearance in the series during the Final Selection test, Kiriya portrays himself to be polite, competent, and somewhat emotionally detached having calmly and politely greeted the trainees in sync with his sister, professionally explaining the details regarding the test. He is somewhat unfazed when Genya Shinazugawa roughly manhandles his sister.[3]

Later, upon his father, mother and sisters' deaths, Kiriya shows an entirely different side to himself, displaying his capabilities as a leader. He immediately jumps into his new position and organizes himself to monitor and command the Demon Slayers on their attack against Muzan Kibutsuji and his Twelve Kizuki,[4] despite just losing half of his family and not even properly having the time to mourn them. He shows more mental fortitude and emotional strength in comparison to his younger sisters, who momentarily broke into tears in grief.[5]

However, once his plan results in the slaughter of many Demon Slayers, Kiriya breaks under stress and stops giving orders, much to his sisters' dismay. He is able to pull himself back together after Kuina slaps him.[6]

History[]

Kiriya was born to Kagaya Ubuyashiki and Amane Ubuyashiki as their third child and only son of five children. He was born after his two older quintuplet sisters and before his two younger quintuplet sisters. As the sole son of the family, he becomes the male heir, the next head of the Ubuyashiki family and the first in line to inherit his father's position as commander of the Demon Slayer Corps.

Synopsis[]

Final Selection Arc[]

Kiriya appears along with his sister, Kanata, at the Final Selection to greet and inform the Demon Slayers in-training of what their last trial will entail.[7]After the test concludes, Kiriya describes the ranking system of the Demon Slayer Corps[8] and asks the survivors to pick an ore for their Nichirin Sword.[9]

Entertainment District Arc[]

Shortly after the battle in Yoshiwara ended with the deaths of Upper Rank demons Gyutaro and Daki, Kiriya's father Kagaya became ecstatic at the news. However, his celebration of the new turn of events was short-lived as his health began to deteriorate quickly, coughing blood as Amane rushed for her children to fetch his medication. Kiriya was summoned to help Kagaya, worriedly calling to his father as he watched him coughing more and more.

Hashira Training Arc[]

Kiriya joined his mother and sister in leading the emergency Hashira meeting. He explained that the only swords of information regarding the marks on Muichiro Tokito and Mitsuri Kanroji were from a journal by a Demon Slayer who used the first Breathing Style. However, when Mitsuri attempted to explain how it manifested on her, it instead left Kiriya bewildered by her demonstration.

Infinity Castle Arc[]

After the death of Kiriya's parents and older sisters, he became the last leader of Demon Slayer Corps and commanded them on the battle of Infinity Castle. He officially stopped dressing like a girl, and adorned a haori similar to his father as well as a talisman made by the friendly demon, Yushiro.

Sunrise Countdown Arc[]

Legacy[]

After Muzan's death, the Ubuyashiki curse would finally end with Kiriya, who realized this when he aged into his 20s and 30s. He spends his hours weeping and holding his wife, children, and surviving sisters.

Over a century after Muzan's defeat, Kiriya is still alive and the oldest living person in Japan. This achievement caused him to be interviewed by a reporter, although he remained unresponsive due to his elderly age. The fact he lived so long is proof that the illness which previously cursed their family is now gone along with Muzan. In addition, he's also pen pals with Yushiro, his only other ally to survive in the modern day.

Abilities[]

Extraordinary Memory: Kiriya has shown extremely good memory. He and his sisters are able to map out and memorize the nearly constantly changing Infinity Castle, creating accurate maps to navigate and guide the Hashira through it in real-time.

Foresight: Similar to his father and his ancestors, Kiriya has a high, almost prophetic intuition, being able to make accurate guesses and hypotheses that were often proven right through intuition alone.

Leadership Skills: Much like his father, Kiriya displays advanced skills in leading and commanding an army into battle despite his young age. He is able to immediately take command of the Demon Slayer Corps' command structure and assist the Hashira as logistical support, guiding them into battle.[10]

Longevity: Due to their relative, Muzan, becoming the first demon, men within the Ubuyashiki family were cursed with a mysterious illness, causing them to usually die in their thirties. However, after Muzan's death, the curse was seemingly lifted. In fact, Kiriya was blessed with a unusually long life, still being alive over a hundred years later and currently being the oldest living person in Japan.

Trivia[]

  • Kiriya shares his Japanese and English voice actresses with Madoka Kaname from Madoka Magica.
  • He and his sisters are quintuplets.[11] Kiriya is the middle child.[12]
  • Despite becoming the family head, Kiriya had wondered for a long time if his sisters were more suitable to be head, as he considers them more intelligent and mentally stronger than himself.[11]
  • After the final battle against Muzan, Kiriya feared that he would die when he turned 20 and that the Ubuyashiki clan would cease to exist. He believed that this was due to happen since the clan had completed their duty of defeating Muzan.[11]
    • As he grew older past the age of 20 and 30, he realized that the curse was truly gone. This made him cry for hours alongside his wife, children, and sisters.[11]
  • Apparently, Kiriya was also quite cowardly as a child, which has factored in him being raised as a girl until the age of 13.[13]
  • In the Kimetsu Academy, Kiriya was described as the 'gentle' one of the Ubuyashiki quintuplets.
