"Baishou Xstasy" was a concert event held to commemorate the release of Sheena Ringo's third album, "Kalk Samen Kuri no Hana." Unlike the typical Sheena Ringo event, this event was performed by the "Noraneko Orchestra," led by Neko Saito. This event was linked to the short film "Kaleidoscope" and the official website "Saga."
