Radiant Spincrystal 91

This wondrous crystal contains a certain rhythm, like something beautiful woven from delicate silk. These items can be found throughout the mainland or from merchants who collect curios. The tune held within this crystal can be revivified in your Serenitea Pot using either "Euphonium Unbound: Winding" or "Euphonium Unbound: Soaring." The tune contained within this Radiant Spincrystal is a mysterious melody from Sumeru.
