315 STARS

Artist

A collective unit of all 315 Production male idols appearing in 'THE iDOLM@STER SideM', the idol-development franchise that originated in arcades and mobile gaming. Members from multiple sub-units including DRAMATIC STARS, Beit, S.E.M, High Joker, W, and Jupiter come together to perform group songs. 'Reason!!', with lyrics by Yohei Matsui and music and arrangement by EFFY, served as the OP theme for the TV anime 'THE iDOLM@STER SideM' and is a fast-paced rock anthem fitting the launch of the animation project, sitting alongside the franchise-defining 'DRIVE A LIVE' as a fan favorite. The unit embodies the world of SideM by transcending sub-unit boundaries.
