**Kosei Shinmon** (新門凰聖, *Shinmon Kōsei*?) is a Third Generation pyrokinetic and the deputy captain of the Fire Force Company 7. He is the younger brother of Benimaru Shinmon, that serves as the self-proclaimed Guardian of the Eighth Pillar.

## Appearance

Kosei is a young and tall, tough-bodied, and attractive young man with sharp red eyes and broad shoulders. He has short messy black hair with bangs hanging below his eyes. Kosei's outfit consists of a white t-shirt with a black vest over it, anavy blue hikeshi-banten with an image of a phoenix on the inside and the Special Fire Force uniform trousers that he tucks into his black boots.
When not on a mission, he usually wears an open purple jacket, a white t-shirt, a light blue sash adorned with an elaborate golden-yellow belt around his waist, and black pants. He is considered by the populace of Asakusa to be handsome, and is the desired bachelor of Special Fire Force Company 7.

## Personality

Like his brother, Kosei shows little interest in any part of Tokyo other than Asakusa, not caring about the rules that the emperor has created, and proudly acts on his own agenda along with his brigade. Kosei is a jovial man, and often comes with quips when fighting. He takes pride in his skills and will not give the time of day to someone he feels is inadequate to give him some fun. Like his brother he is honest, but knows when that honesty can be interpreted as rude. Following the example set by his father and brother, Kosei prefers being called **Shinmon Kosei**, following their original country idealist mindset. Despite this, he is much more lax about it, and does not mind enough to call someone out on it, if they call him by his given name first. He is deeply connected to the people of Asakusa, and cares about them immensely, becoming saddened by having to put an end to the life of someone he once knew.

When fighting Infernals, he is straight to the point, not wishing the victim to suffer. Though he has a tendency to jump straight into battle with no plan, he believes in his own strength and his powers to pull him through. Kosei admires his brother, and will go to many lengths to prove himself to Benimaru. Though he does not want to admit it, he cares deeply for Himea Sagamiya, and will risk life and limb to keep her safe. He enjoys their bickering and name calling, but sometimes is unable to apologise should they take it too far due to his pride.

## Background

Kosei's mother infernalised during labour, which left only his older brother to take care of him. They were taken in by Hibachi Shinmon, who raised them like his own. When he became old enough, he was allowed to join the fire department that put infernals to rest, but was not taught the Iai Shutō like his brother. Hibachi still trained Kosei to hone his Ignition Ability, and taught him how to fight hand-to-hand.

## Abilities

Kosei is regarded by Konro as the second strongest officer in the Special Fire Force, only surpassed by his brother, Benimaru, and is believed to have surpassed their old master, Hibachi Shinmon, who was a famous and powerful pyrokinetic as well. He was able to best Rekka Hoshimiya in single combat effortlessly, and able to overcome a Demon Infernal with minimal effort. Thanks to his use of Hysterical Strength, he is able to call forth his full potential.

**Master Hand-to-Hand Combatant**: Kosei is an extremely skilled and powerful hand-to-hand combatant, able to fight on par with his brother.

**Immense Speed**: Kosei is extremely fast and has extraordinary reflexes. He is capable of moving faster than the eye can see and outpace even the fastest of opponents. Kosei is also able to react to Shō Kusakabe's Severed Universe technique after only experiencing it once and is able to fly faster than Shinra.

**Immense Strength**: Kosei possesses tremendous levels of physical strength. As a child, he could match the strength of his master Hibachi, and was capable of restraining a grown man with his bare hands. After permanently unlocking Hysterical Strength, Kosei’s strength allows him to fight on par with his brother for several hours. Kosei’s natural physical might combined with his innate martial arts mastery makes him an incredibly powerful opponent to face in close quarters, which is further amplified by his pyrokinetic fighting style.

**Whip Mastery**: Kosei is quite masterful with a whip-like weapon. When fighting Infernals, he is able to move the length of his whips with little effort and controls the direction of the attack with great ease in order to confuse his enemy. He can also wield his whips in both his right and left hands.

**Unmatched Durability & Endurance**: Kosei possesses incredible levels of durability, capable of completely nullifying strikes from Demon Infernals, Doppelgängers, and even insanely powerful individuals such as Dragon and Charon. He is also able to have his Ignition Ability activated for days at a time, and is able to fight without a break for just as long.

### Pyrokinesis

Kosei's Ignition Ability, aptly named "Phoenix", first manifested when his mother was Infernalised and purifed during his birth. It allows him to take on the form of a phoenix, gaining flaming wings on his back and three tailfeathers. When activated, Kosei's physical attributes is boosted, and is able to create devastating fire-based attacks and gain a high resistance towards most heat-based attacks. The flames can also be used to increase the force of physical attacks even further. The Ignition Ability also allows Kosei to use his tailfeathers as whips, which he can materialise from anywhere on his body.

The main power of Kosei's Ignition Ability is the **Flames of Resurrection** (復活の炎, *Fukkatsu no Honō*?). As such, he is unable to develop Tephrosis. Kosei is able to heal and survive practically any wound, and is granted a power boost for a short time after sustaining high enough damage. This power boost can be voided if the attack is lethal enough, like when Sho Kusakabe cut off Kosei's head, which took him six hours to recover from. When in this form, Kosei becomes as strong as his brother. Kosei can distrubute this fire to his allies, healing them as well, however, his flames are less effective on anyone other than himself.

#### Techniques

* **Phoenix's Wings Rise** (鳳翼天翔, *Hōyoku Tenshō*?): Kosei gathers forces of wind and heat into a concentrated point, unleashing them in a single blow. This attack covers a wide range of distance. It may also be used on multiple enemies at the same time.

* **Flaming Wings of the Phoenix** (燃える不死鳥の翼, *Moeru Fushichō no Tsubasa*?): A defensive move that has Kosei jump in front of someone he wishes to shield from an attack. While midair, he forms a protective swirl of fire in front of him, out of his wings, in order to block the attack in question.

* **Phoenix Great Flame** (不死鳥の豪炎, *Fushichō Gōen*?): An attack where Kosei launches a swirling fireball in the shape of a phoenix that is hot enough to melt stone. Its power is strong enough to blast through one of Ritsu's Giant Infernal in one hit.

* **Fire Storm** (火災嵐, *Kasai Arashi*?): Flying into the air, Kosei shoots the flaming feathers from his wings at high speed. This attack covers a wide area.

* **Crimson Moon** (紅月, *Akatsuki*?): Kosei uses incredible amount of firepower, and fires a huge fireball at his opponent that is strong enough to defeat a Demon Infernal; creating an explosion which resembles a red moon. It is also powerful enough to turn the users fire blue, as shown when Konro used Crimson Moon for the first time.

### Adolla Burst

Having the Adolla Burst, Kosei can be temporarily empowered with the Adolla Grace through an Adolla Link to a person who originates from Adolla, or someone who is already graced. The connection with his Adolla Burst is strengthened according to the intensity of his desire.

Under Grace, Kosei can call upon the **Genesis Flames**, and enter something he calls **Phoenix of Destruction Form**. In this form, he gains two more tailfeathers, his wings becomes more jagged and larger, and he is able to access the **Eternal Flames of Purgatory**. These flames are inextinguishable by wind or water, and burn so quickly that regenerative techniques cannot keep up with them, leaving the victim's body completely charred in mere moments.

#### Technique

In this form, Kosei has only one named technique. Once this technique has been used, his Adolla Grace will forcefully end, and cannot be used for 24 hours.

* **Eclipse** (皆既食, *Kaikishoku*?): Kosei concentrates the intense **Eternal Flames of Purgatory** along the outer skin cells of his fist. His wings and tailfeathers disappears, and the only sign that he using his powers is his glowing eyes and his fist becomes scorched by fire. It neither burns nor erupts, but anything his fist touches, no matter how hard is eradicated to nothingness. Hibachi Shinmon considered it the ultimate pyrokinetic attack, likening it to getting struck by the sun, and the technique was the main factor in his decision to not teach him Iai Shutō, as he thought it could be too dangerous to be able to launch an attack like it at range. Due to the intense heat, it cannot be manipulated by Second Generation pyrokinetic, and Inca Kasugatani cannot detect it with her Ignition Ability.
