Rekka Hoshimiya

is a Third Generation Company Commander of the 1st Special Fire Brigade, who is responsible for creating artificial Flame Humans in the Shinjuku area of Tokyo using the Bugs.

Appearance
Rekka is a young man with short, spiky dark-coloured hair that falls just above his eyes, bushy eyebrows and dark iris' with star-shaped pupils. Rekka's outfit consists of a dark-coloured cassock, topped by a light overcoat-like garment with a high collar and a skirt-like garment, dark shoes and a pendant with a cross-like symbol as a charm — an outfit, which is shared amongst the Company Commanders of the 1st. He usually carries an ecstatic facial expression, along with his demeanour. Rekka's eyes are sometimes depicted as being traditionally shaped stars; such times as when he is fighting, angry or excited.

Personality
Rekka is an eccentric and enthusiastic individual who gets easily excited at the thought of combat. He abides to the etiquette of the 1st Special Fire Brigade and has shown to have a welcoming presence. Rekka has great determination and is passionate about fighting, during which he doesn't hesitate to praise people whom he finds deeming to be praised. He was admired by Tamaki for his strange, yet hot-blooded attitude. Despite these qualities, however, Rekka has a dark, malicious and manipulative side to him; He shows no remorse in his actions, which involve him turning innocent people into Flame Humans using artificial means and killing them immediately afterwards, showing a passion for violence. Rekka has an obsessive complex with him trying to find somebody compatible with the flames and his research into the phenomenon. In contrast to the other Priests, Rekka acts savagely and doesn't have high moral standards when it comes to other people, as he's shown to carelessly harm them in various ways.

Abilities
Rekka is a Third Generation, who has gained the ability to generate flames through his arms. He has great physical strength, being able to suffocate Tamaki, to the point of her losing consciousness, or kill a Flame Human with a single punch. Rekka also has great reflexes, being able to dodge a myriad of Ignition Ability made missiles with ease. His Ignition Ability, Star Fist Thrust, allows him to land more powerful punches on his targets, by using the flames to launch his fist forward. Using the same motion, Rekka can also launch his flames forward from his fist if the target is out of reach.

VS. 1st Special Fire Brigade arc
After the scuffle between the 5th and 8th Special Fire Brigades, Rekka and his fellow team-mates, Foien and Karim, are approached by Leonardo Burns and together they discuss the event. Later, when trainees from the 2nd, 5th and 8th Brigades arrive at the 1st Special Fire Fighting Cathedral and their training regiment begins, Rekka is pitted against Takeru, who astonishes Rekka by his raw power as a Third Generation. Takeru launches a myriad of missiles at him, but Rekka evades the attack, forcing Karim to freeze the missiles. Sometime after training, when a Flame Human was spotted in the Shinjuku District, Rekka takes lead of one the squads. During the mission, Shinra spots a person creating a Flame Human using artificial means and finds Karim and Rekka at the scene of the crime, but does not approach them about the incident.

Sometime later, he thanks Tamaki for assembling people to an abandoned building, where he claims to know of a prayer that can protect people from succumbing to the phenomenon. He then hugs Tamaki, suffocating her until she collapses, then injects a parasite into a woman, turning her into a Flame Human. Rekka, however, instantly kills her with a single punch and deems the experiment a failure, getting frustrated with the fact that he cannot find a person with a compatible spark. After exchanging a few words with Tamaki, he continues conducting his experiment, injecting Takkun with the parasite.
