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 that 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, which give the impression of having 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 belief in only fighting those he deems as worthy, a trait showed 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 is not at his desired 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. Ouma can also use his wind to bend the light in his surrounding and make himself invisible.

Master Swordsman: Ouma is extremely skilled in swordsmanship, easily defeating Tohka and Stella in their first fight. He even managed to defeat Ikki with ease when he challenged Ikki, a testament to Ouma's swordsmanship mastery.

Device
Ryuuzume (龍爪 lit., Dragon Claw): Ouma's Device that takes a form of an over meter long Nodachi.
 * Kusanagi : Ouma's strongest Noble Art. By condensing his magic into Ryuuzume, Ouma can compress the surrounding air into his Device, creating powerful storm like blades that can easily surpass 50 meters in height. The Kusanagi's full strength easily surpass even Stella's Katharterio Salamandra and was able to turn the Hagun Academy's school buildings, practice arenas and asphalt paving the roads into rubble.

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.
