Zutto Mayonaka de Iinoni. (Japanese: ずっと真夜中でいいのに。, I wish it was midnight all the time.), abbreviated in English as ZUTOMAYO (stylized in all caps) is a Japanese rock group that debuted in 2018. Secretive by nature, the group has never released a full member list, crediting different people for music, arrangements, and music video production each time. The only reoccurring member is the vocalist, an unidentified woman named "ACA-Ne" (ACAね), pronounced "Akane".
Despite the little information released, the group is commercially successful. Zutomayo's three EP's have reached 8th, 1st, and 2nd on the Oricon Albums Chart, respectively. The group was also invited to perform at the 2019 Fuji Rock Festival a year after their debut.
Zutomayo released Gusare (ぐされ) on the 10th February 2021 featuring songs One's Mind, Can't be right, Study Me (Obenkyou Shitoiteyo), Hunch Gray, Have A, Engine Oil, Darken, Milabo, Loneliness, Crop, Hypersomnia, Fastening and Inner Heart.
