Solennel Company is a six-member orthodox, refined-style idol group built around the concept of a “corporate organization.” Each member holds a company title, and fans are affectionately referred to as “employees.” The lineup includes Kokorone Kana (President), Shizukuishi Meno (Secretary Department), Aiki Yukari (Sales Division I), Yamaguchi Honoka (Sales Division II), Suzumiya Azu (Planning Department), and Miyase Rena (General Affairs). Originally launched before rebranding, the group marked a ReDEBUT in April 2025, signaling a refreshed musical direction and expanded live presence. Known for melodic compositions and polished choreography, Solennel Company has gained attention for high-quality music videos and live footage, benefiting from professional production expertise behind the scenes. Representative songs such as "Koi Ha Timing"(2022) and "I Fell in Love With You"(2022) showcase their blend of emotional pop melodies and clean, coordinated performances. With the release of "TrueDreamRefrain"(2026), the group further developed its uplifting, melody-driven style.
