Powerless, also known by his Vocaloid P-name Muryoku-P, is a Japanese composer and producer. Getting his start making symphonic rock and metal for the Vocaloid community, Powerless would later on branch into contracts for anime and video games as studios picked up on his talent for complex, moving arrangements even in the complete absence of a real orchestra.

His credits include Re:Zero, Deemo, Babymetal, Lanota and Arcaea.
