**Saber** (セイバー, *Seibā*) is the servant of ??? in the ??? Holy Grail War.

*"Life is a series of decisions. You never have unlimited options or unlimited time to think, but what you choose in that instant defines who you are."* - Kyojuro Rengoku

## Profile

### Identity

Saber's true identity is **Kyojuro Rengoku**, a Demon Slayer of the Demon Slayer Corps and the late ****Flame Pillar**** (炎えん柱ばしら, *En Bashira*?).

He was the eldest son of Shinjuro Rengoku. His father was known as the Flame Pillar of the Demon Slayer Corps until his unexpected retirement. Kyojuro also had a younger brother, Senjuro, who trained alongside him until their father ceased to teach them. Kyojuro and Senjuro lost their mother sometime after she gave birth to Senjuro due to having developed an untreatable disease and being left bedridden up until her death. Despite his father having stopped teaching him, Kyojuro trained by himself to reach the position of the Pillar, using the guidebook of the Breath of Flames style, a book which had only 3 volumes. After reaching the rank Kinoe, the highest Demon Slayer rank, he defeated the former Lower Moon 2, Hairo, and became the Flame Pillar of the Demon Slayer Corps after the battle.

### Appearance

Kyojuro was a young adult of tall stature and muscular-athletic build. He had long bright yellow hair with red streaks akin to flames along with two shoulder-length bangs and two chin-length bangs on the side of his head, black forked eyebrows, and golden eyes that fade to red with white pupils. He was known to be charismatic and had an air of great optimism, having an enthusiastic smile plastered on his face nearly all the time.

Kyojuro wore a paler brown version of the regular Demon Slayer uniform, which consisted of a brown gakuran jacket, a white belt around his waist and tattsuke-hakama pants. Over this, he wore a haori with a white-yellow gradient pattern and red flame-like ridges at the end that his father Shinjuro once worn and more than likely his father worn when they were the Flame Hashira respectively. Finally, he wore red kyahan with yellow flames erupting from the bottom-up, with pale brown tabi socks and a pair of white zōri with red straps.

When he first joined the Demon Slayer Corps, he only wore the regular Demon Slayer uniform but as he rose up the ranks, Kyojuro started wearing a completely white haori before donning on his signature flame-patterned one.

### Personality

Kyojuro was greatly enthusiastic in regard to his duties as a Hashira, and often came across as cheerfully eccentric. He was amiable, pure of heart, and boasted extraordinary technique and swordsmanship stemming from strict practice and discipline. He was an honorable warrior who adhered to his code of morals and principles that was instilled into him by his mother at a young age; the most significant being his belief that those who were born strong have a duty to protect the weak.

Kyojuro also loved his family immensely, displaying great respect and worry towards his father, Shinjuro Rengoku, despite him growing slowly more aggressive and apathetic towards Kyojuro. He was incredibly encouraging and optimistic towards his little brother, Senjuro Rengoku, believing in him and wishing him the best no matter what. This was further accentuated during his death where his final words for his father and his little brother were "take care of your body" and "follow your dreams no matter what". Kyojuro also believes that if someone lacks immense skill, their hard work towards their dreams and desire to help people doesn't count for nothing.

Beneath his enthusiastic demeanor, Kyojuro was very logical and tactically intelligent, acting quickly and precisely in battle, especially when the lives of others are on the line. Kyojuro was also great in seeing talent in others, even in Nezuko Kamado, a demon which he wanted to kill beforehand, after seeing her risk her lives to fight and protect others. Though he was extremely optimistic, Kyojuro does sometimes have a sense of foreboding that those he believes in might die, especially his friends which he care deeply for. He, like most Demon Slayers, absolutely detests demons, usually because of their heinous deeds or because of their clashing morale values. Despite this, Kyojuro recognized and accepted Nezuko as a member of the Demon Slayer Corps after seeing her risk her life to protect innocents, showing that Kyojuro was capable of not letting his hatred for demons cloud his judgement.

## Abilities

As a Hashira of the Demon Slayer Corps, Kyojuro was a very powerful and skilled combatant. Before he took his father's place, Kyojuro was already shown to be an amazing fighter. He successfully avenged the death of the 9 Demon Slayers that died to the Flute Demon by himself and later managed to singlehandedly defeat Lower Rank Two, Hairo, who even appraised his swordsmanship before he died. Moreover, his father, Shinjuro Rengoku, stated that, after he stopped teaching his son, Kyojuro trained himself to become a Hashira by learning from the guide book of the Flame Breathing style, a book which only had three volumes.

As another testament to his abilities, Akaza, the Upper Rank Three and one of strongest of the known demons, acknowledged and praised Kyojuro's strength. He even went as far as to offer to turn him into a demon so he could surpass his human limits and become stronger, something he only offered to swordsmen whose abilities he believed were refined to their utmost. Akaza also complimented his fighting spirit and stated that it was getting close to the "Realm of the Highest," which implied that he was incredibly close to obtaining the **Transparent World** (透すき通とおる世せ界かい, *Sukitōru Sekai*?) and the **Selfless State** (無む我がの境きょう地ち, *Muga no Kyōchi*?).

As a Hashira of the Demon Slayer Corps, Kyojuro was one of the most powerful and skilled swordsmen in the entire organization. Additionally, Kyojuro is part of the Rengoku family which has an impressive lineage of powerful swordsmen and Flame Hashira, giving Kyojuro an edge in developing and polishing his swordsmanship. His extraordinary swordsmanship skill has been displayed on multiple occasions across the series.

In his battle against the former Lower Rank Two, Hairo, Kyojuro was able to out-wield the demon's bushido sword style, which Hairo appraised as he was decapitated. Kyojuro's precise blade work could also slow down Enmu in his fused form, which gave him the opportunity to explain his plan to Tanjiro and Inosuke. His mastery of the blade is best showcased during his battle with Akaza, in which he was more than capable of fighting on equal ground with the Upper Rank who has killed countless Demon Slayers and even Hashira over the last century, even to the point that Akaza constantly praised Kyojuro's swordsmanship.

### Noble Phantasm

#### **Breath of Flames: Ninth Style-Purgatory; "Swarming of Rengoku Flames"**

The most powerful Flame Breathing technique. The user takes a high stance with their sword before dashing forward at high speeds. The technique is powerful enough to completely carve out the ground in its wake. This technique has seemingly took the form of a flaming Japanese dragon that envelopes the user as they are charging towards the target.
