On June 16, Cube Entertainment announced that CLC will be returning to Japan to release their 2nd Japanese mini-album, "Chamisma".

It is also the group's first original Japanese track, which shows the lovely charms of the 7 members of the group, including Kwon Eunbin who will be joining them in Japanese promotions for the first time.
The album will be released in 3 different versions: Type A (CD), Type B (CD+DVD) and Type C (CD+DVD). The Type B version of the album includes a track and music video of Chamisma featuring Jung Il-hoon of BTOB while the Type C version includes a DVD of CLC's first Japanese showcase "First Step".
