Intelligence: Has years of combat experience, but is arrogant and doesn't know when to fall back
Weaknesses: Very arrogant, doesn't know when to retreat, usually refuses to fight against weaker opponents, Kusanagi gets weaker with each use after the third, destroying Ryuuzume should deal enough mental damage to knock him out
- Kusanagi (月輪割り断つ天龍の大爪 lit., Moon Severing Sky Dragon's Talon): 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 surpasses even Stella's Kalsariteo Salamandra and was able to turn Hagun Academy's school buildings, practice arenas and asphalt paving the roads into rubble. Kusanagi, however, has a flaw, evident when Ouma noted a decrease in power by the third usage during his short fight against Nene.
- Shinkuuha (真空波): A popular offensive technique among wind users that tears through air, creating a small corridor of vacuum.
- Mukou Kekkai (無空結界): Ouma creates a powerful updraft to deprive his opponent of oxygen and mobility. This technique leaves the opponent with only ten minutes worth of oxygen if they don't do anything, and one minute if they continue to fight.
- Fuujin Kekkai (風神結界, Wind God Barrier): A defensive Noble Art, where Ouma stabs the ground with Ryuuzume, creating a tornado around him.
