Ouma Kurogane

Ouma Kurogane is the older brother of Ikki and Shizuku Kurogane. He is a member of Akatsuki.

Appearance
Ouma is a young man with very long black hair, which covers most of his forehead, and all of his back. He has yellow eyes which seem to have no life in them as they seem dead. He is seen wearing a black shitagi, as well as a white Haori, with black sleeves, that seem to have gray stripes on each sleeve. Ouma is also seen with a large, x-shaped, scar across his face, although underneath his clothing it is revealed that he has a plethora of scars and marks due to his training with Akatsuki.

Personality
A man of few words, Ouma has little interest in anything besides fighting strong opponents to test the limits of his strength. To that end, Ouma keeps a believe of only fighting those he deems as worthy, a trait shown by the instance, where he only shows interest in fighting with Stella but is more than willing to cast aside his interest towards her away if she's not at his desire level.

History
Not much is known about Ouma's past aside from the fact that he went missing 5 years prior to the series.

Incident of Okutama
Ouma appears along with Reisen Hiraga who was sent to test the ability of Tohka Todo. Ouma, however, was having more interest in Stella, claiming that she's the only reason he joined them and if Stella isn't up to the level then he isn't interested in her.

Abilities
Wind Manipulation: Ouma's ability as a Blazer. Ouma can produce wind and use it in fights.

Light Manipulaton: The second of Ouma's ability. Ouma can control light which he can use to make himself or his opponent invisible.

Trivia

 * Ouma was claimed to be the only A-Rank Apprentice Knight in Japan which is proven untrue as Amane Shinomiya is also an A-Rank Blazer.
