Ryuhime Kashin is the leader of the Wu Xing Shadow Ninja Force, as well as a former candidate for the Trinity Seven of Invida and acquaintance from Levi's past. The two would reunite after coming into conflict over the Mythical Weapon Murasame.
Ryuhime has a confident and competitive demeanor, often finding opportunities to declare or display her capabilities, particularly towards Levi. Nevertheless, despite her self-assertiveness, Ryuhime will still acknowledge those with strong abilities, being aware of their strengths. However, her attitude can quickly become apprehensive or disturbed upon encountering an unexpected situation, although she usually recovers her composure.
Ryuhime is a young slender girl with long light hair adorned with a star hairclip on her right bang and a small dark garrison hat on the opposite side. Ryuhime's attire consists of a dark collared blouse with a cravat tie and short skirt with ruffles on the bottom held by a large belt, along with a dark cape. Additionally, she also wears dark thigh high socks and boots.
After capturing Charme, the Wu Xing Shadow Ninja Force ambush Levi who had tracked Charme to their location. While Levi barely manages to avoid the onslaught, she recognizes their identity due to the nature of their magic. Nevertheless, Ryuhime remains confident before introducing herself and declares that she will defeat Levi.
Dragon OrbEditAs a wielder of the Dragon Orb magic from the Invidia Archive, Ryuhime can interfere with the world by controlling the five elements of the dragon, becoming capable of even splitting dimensions. Possessing the element of gold, she can utilize the remaining elements, wood, fire, earth, and water, through each of her subordinates. Furthermore, Ryuhime can also them through the talismans she stores on her hat. Its power is capable of defeating a Code D in one hit.
Formerly a candidate for the Trinity Seven of Invidia, Ryuhime's strength has been noted to nearly equal against other Invidia mages such as Levi and Lugh.
Ryuhime possesses four talismans that she maintains on her person, usually on the brim of her headwear. Each talisman corresponds to one of the remaining members of the Wu Xing Shadow Ninja Force whom she can summon.
Levi Kazama - As former acquaintances, Ryuhime would reunite with Levi during her pursuit for the Mythical Weapon Murasame. In particular, Ryuhime is competitive towards the Trinity Seven, often declaring that she will defeat the ninja. However, despite her confidence, the Gold Dragon Sorcerer respects Levi's strength, as well as being quite knowledgeable about her abilities and vice versa. Notably, they were both candidates for the position of the Trinity Seven of Invidia, although Levi would ultimately receive the title.
- The translation of Ryuhime is "Dragon Princess".
