Rittor Music, Inc. (Headquarters: Chiyoda-ku, Tokyo; President: Daisuke Matsumoto), which handles music-related media business within the Impress Group, will release "Kon - Mazari Book -", the first artist book by the 7-member idol group "Mazari", on August 25, 2026.

Mazari is an idol group whose concept is "mixed hatred" such as curses, jealousy, revenge, and the darkness of the heart. The members are Mana Se Manase, Meron Anti Shiwi, Aku Zuikyo, Homura Jabami, Rem Kuka, Koneko Pan, and Urin Shinzou (deceased in 2025), a total of 7 members. Upon their formation in 2024, artist photos of them wearing Noh masks, obscuring their faces, were released, generating significant buzz online.

Their sound also possesses a dark, heavy beauty befitting the explosion of negative emotions, and being based in Nagoya, it has been highly praised by music fans for evoking the "Nagoya Scene" of the 90s visual kei scene. Leda (Gt, Ba) participated in the sound production, which is also noteworthy, earning high praise not only from idol fans but also from visual kei and metal fans. Furthermore, in recent years, they have embarked on a tour with a band set featuring renowned musicians such as Hazuki (Gt, NEMOPHILA / KOIAI), Ray (Gt, DEVILOOF), Akihito (Ba, lynch.), and Hibiki (Dr, MAVRO OPERA). Their death growls, shouts, and intense dance performances have been further refined, and their stage presence captivates many fans.

This first artist book by Mazari includes newly shot photos, member interviews, self-produced pages revealing members' preferences, coordination photos of the original yukata "Gekkachuuki" created in collaboration with the modern kimono brand "iroca", interviews with Leda and the band members mentioned above, and the band score for "Kokkuri-san". It is a volume that allows for a deep understanding of Mazari's current state, which has been shrouded in mystery until now.

Additionally, this book features four types of covers, each sold through different channels. Please note that some cover versions are only available for pre-order online or will be sold in advance at live venues. The content of the book is identical for all versions, with only the cover differing.
