Tsubasa decided to go into music :D Her singer name is Milky Bunny. At the end of July she released her debut single called Bunny Days. The song is about the feeling you have when you fall in love, the 'fluffiness', and the journey from just friends to lovers. This song will be used for Candy Doll adverts. If you look carefully, you can spot use of her brand.
The song itself is quite catchy, but sometimes her voice sounds very strained. Nevertheless she looks very cute, and I hope she keeps up the new image of Milky Bunny in her upcoming songs.
