What is the Artist Collaboration? In this project, popular artists provide newly written songs for idols. MVs with new illustrations matching each of the six labels' worldviews are planned. The first was handled by Hige Driver, the second by Funta7, and the third by Gesshoku Kaigi.

EclipseVoice Profile An artist-oriented label with a dark worldview, centered on the overwhelming vocal power and performance of the young diva Ayana, supported by the twins Mika and Ruki with perfect combination. Their energetic style based on hard rock creates a large whirlpool that draws in everyone around them. They are idols who captivate you with their noble and powerful brilliance.

Gesshoku Kaigi Profile Gesshoku Kaigi is an unprecedented band-style music guild where all members are lyricists, composers, and arrangers, as well as seasoned artists. They combine their skills and personalities at a high dimension through the chemical reaction of 'co-writing.' They have provided songs for Momoiro Clover Z, Hey! Say! JUMP, Hypnosis Mic, Charisma, and more. Their first solo live at Daikanyama UNIT in October 2019 was sold out, and they performed at the EVIL LINE RECORDS 10th anniversary festival 'EVIL A LIVE 2024' in May 2024. They celebrated their 8th anniversary on June 15, 2025.
