Yunagi

The Yunagi (凪水 Calm Water) is a white-wood Shirasaya (a katana without a tsuba/guard) wielded by Setsuna Sakurazaki throughout Negima! Magister Negi Magi. Its design is typical of the swords found in the Shinmei-ryu School of Swordsmanship, possessing two bells tied with red string at the base of the grip.
