SQ

SQ (スケア SUKEA) is a unit series under the management of TSUKINO TALENT PRODUCTION and features the units SolidS and QUELL.

Overview
Initially, the series only contained SolidS, who debuted shortly after the ALIVE units, while QUELL weren't introduced until late 2016. Both of the units of SQ were featured in TSUKIPRO THE ANIMATION alongside the units of the ALIVE series.

Similar to how the TSUKIUTA. units are themed after the twelve months and the VAZZROCK members each represent a type of gemstone, the SQ units together with ALIVE represent the four elements (fire, earth, water and wind), with SolidS being fire and QUELL being water.

Mascots
The SQ units have the same mascot type, known as Lizz. Lizzes take the shape of a squirrel, which is a play on the Japanese word for squirrel [リス Risu] and the katakana for SolidS [ソリッズ Sorizzu]. Each member has their own Lizz named after their respective fan club and with the Lizz's body sharing its color with that characters representative color.

Behind the Scenes
Though ALIVE and SQ are featured together the two series have separate artists, with SQ's series illustrator being Satsuki You.

Unlike the units from the ALIVE series, SolidS and QUELL do not share a single producer. In-universe Takamura Shiki is the producer for SolidS, but in reality they are produced by Takizawa Akira who is also responsible for both units from ALIVE as well as the September representatives from the TSUKIUTA. series. QUELL on the other hand have Izumi Shu as their in-universe producer while in reality they are handled by Takeshi Hama.
