The Barasensō (ばら戦争, War of the Roses) is one of the swords of the Seven Ninja Swordsmen of the Mist, formerly wielded by Rosuto's Father. It is now in possession of Rosuto Nagakura and the replacement blade for the famed Samehada.
The blade itself assumes the form of a six-part segmented blade; each segment is wider than the one preceding it from the hilt with two pick-like protrusions on the front and back of each segment, with the ones on the front much longer than the ones at the back.
Barasensō's segments grow in number almost without limit. The segments are connected by a stretchable thread, making Barasensō more useful as a whip than an actual sword, thus living up to its alternative name "Whipsword". Though it can serve as a regular sword just as easily. Rosuto showed his skill at maneuvering the lengthened blade by forming an omni-directional cage around a small group where he then pulled the extended blade taught around them, thus lacerating those trapped within.
- The name, Barasensō, is translated to War of the Roses: a series of dynastic wars fought between supporters of two rival branches of the royal House of Plantagenet: the houses of Lancaster and York (whose heraldic symbols were the "red" and the "white" rose, respectively) for the throne of England.
