is a Japanese animation studio based in Tokyo. Revoroot was founded as a subsidiary of Twin Engine, but as of 2021, it operates as an independent studio. The studio was originally headquartered in Nishitokyo, but relocated to Suginami in 2022. Following the move, part of Revoroot's staff stayed in Nishitokyo to operate as a separate studio, Crew-Cell, which would continue to work as a subsidiary of Twin Engine. Kazuki Emani, the CEO of Revoroot, is also the CEO of Crew-Cell.
