The continuation of Kuuden Noise no Himegimi. Hosaka Mao, an incredible guitarist currently in high school, has joined Altago, a rock band aiming to go pro. Mao's classmate & best friend Hasekura Yokiko has a spectacular singing voice but doesn't want to join the band as she doesn't like standing out. The newly revived Altago's first live performance was a disaster, but things have since calmed down as the band prepares for their next live show. — ["Kuuden Noise no Himegimi" was originally serialised in Monthly Birz, a magazine that suspended operations in 2018. Chapters 1-21 were released in three volumes with Birz Comics. Another magazine, Evening, then picked up the series and the story continued from where it left off (albeit with the new name "Kuuden no Himegimi"). The first volume of "Kuuden no Himegimi" (thus technically the fourth volume in the series) was released in 2019.]
