753 x Absolute Castaway - Another Flower

Mamyukka - 百鬼夜行草子 (Hyakkiyakou Soushi)
Considering Mamyukka's track record, it's no surprise that they would release a youkai vocal album sooner or later. The sound leans more towards traditional Japanese music, but the playfulness that is the circle's signature sound is present. They are going to release a regular version and a limited first edition. The limited first edition will include a novel and other things.
Ether - 機械都市インティモーラ (Kikai Toshi Intymla)
Ether's new vocalist, Erumu Nagi, will be making her debut in this new mini album. Nagi started out as a NicoNico Utattemita.
