正倉院笹鳴

A black haired Cat God, who has also grey eyes. Sasana is Mayu's fiancé, and the reason for this was because of their dad's (they just thought Sasana and Mayu make a good 'couple'.) Sasana is usually happy, but when she's close to Mayu she's really happy, calling her 'Mayu-sama' and talking always about that she (Sasana) is ready for marriage.
