REOL is a Japanese musical unit built around vocalist Reol, music producer GigaP, and visual director Okiku. Before they officially came together, Reol and GigaP had already been collaborating closely—they'd even put out an album called No Title while Reol was still working as a solo artist. Once all three joined forces and signed to Toy's Factory in 2015, they released their debut album Sigma on October 19, 2016.
The group announced they'd be disbanding after a final live show in October 2017.
