Now, goods of Nameko are sold at every place.
Furthermore, they release a compilation album on July 11.
In Japan, a music CD of a social game and the social application that made a hit was released several times until now. However, the characteristic of the CD of this Nameko is that participating musicians are really fans of Nameko. Musicians are players of Nameko Saibai Kit. Therefore they made a musical piece with love to Nameko.
