The Niten (二天:風道, Two Heavens) was the sixth form of Zanjutsu combat taught solely within Horiwari; making it a style unique to the Ryū Order and the Dragonforce. Following the Collapse the Niten was used almost exclusively by the Six Directions, specifically Kentaro Hiroshi, though some, such as Itazura Kori, had a working knowledge of the form itself. The style was co-developed by Kenji Hiroshi, Meian Shiba and Kentaro Hiroshi, and only truly mastered by the latter. By the time of The Collapse the Niten was considered nearly extinct.
