'Zanka' debuted in April 2023 as the third idol unit from QOOLONG, home of the WAGAMAMA RAKIA and Night Owl.The four members are Mako Serizawa, Sayaka Jigen, Miina, and eve.Each of them had a completely different history as an idol in the past, and although they had once walked away from their dreams due to the breakup or departure of their groups, they were unable to give up on their dreams and restarted their endeavors.The album consists of five songs that are being released on CD for the first time, without re-recording of earlier songs.The songs are based on rock music, but each song has a different expression, and once you hear the melodies that bring out the individual voices and personalities of each of the four members, you will not be able to get them out of your ears!
