DMM Group has announced the formation of Gleestone, a new animation studio tasked with managing projects from initial planning through final production. According to the company, the studio's leadership includes president and CEO Naokazu Tsuruta, who also heads DMM Group's content creative unit, and COO Kensuke Tateishi. The studio's stated philosophy focuses on creating long-lasting content that avoids chasing short-term industry trends. This expansion follows DMM's previous entries into the anime sector, including the 2017 launch of the DMM Pictures licensing label and the 2023 establishment of the CUE animation production studio. DMM Pictures has contributed to over 120 titles to date, such as Fire Force and Blue Period, and served as a planner for the 2022 series Shinobi no Ittoki.
