Ikaruga (斑鳩) is a mysterious group of ninjas in Calvard.
Like the shinobi of East Zemuria, the Ikaruga are dressed in black, covering their face and body. They wield Eastern-styled weapons, such as the shinobigatana and kunai. Ikaruga draw from a wide range of martial arts schools, such as the Eight Leaves One Blade, Black God One Blade (黒神一刀流) and Hazy Moon (朧月流) schools.
In January S.1208, four members of the Ikaruga - two low-ranking scouts, Kurogane and Hime - crossed paths with Rean Schwarzer in the mountains near Longlai, Calvard, during Rean's unsuccessful search for his missing master, Yun Ka-fai, who seemed to have some relation to Ikaruga. The members stated that their "contract" were to have them observe anyone who came by the area, unless they were a "person of special interest". Although Hime managed to overpower Rean, the mercenaries allowed him to leave, telling him that he would not find Yun here.
Kurogane (クロガネ) is a practitioner of the Hazy Moon school. With enormous physical strength, he wields two double sabers in an inventive fashion that allows them to be joined together to create a four-bladed cross sword. Double sabers are considered obsolete Dark Ages weaponry in West Zemuria that require enormous skill to use. Kurogane proved to be much more powerful than the two scouts, and managed to force Rean to activate his Lucid Spirit Unification, which allowed him to catch Kurogane off guard. Rean's counterattack was interrupted and Kurogane saved by Hime.
Kurogane is the only known user of double sabers, aside Crow Armbrust.
Hime (姫, "princess") is a silver-haired woman in her early 20s wielding a jet-black odachi decorated with red and silver designs. She is apprenticed under Yun Ka-fai and specialised in at least the Zeroth Form, Twin Shadows (
