Uchiwahi are two sets of fans that Yukirei utilized in the past during the waning days of the First Shinobi World War. Made of a tough, layered ebony base that allowed the fan to be folded, the spikes were made of thick, strong ice that was resistant even to extremely high temperatures, having been used to block a Fireball jutsu at one point. The two tessen are perfectly balanced, allowing for light carry and easy throws. The fans are sensitive to Yukirei's chakra, allowing her to manipulate their paths, even pulling them back once she hits her designated target with the tessen.
