http://atani.me/YAGOO-2024Interview with Yagoo, I'll just post the part that mention Mori
>Mori Calliope has been involved with Suicide Squad ISEKEI by performing the ending theme “Go-Getters,” appearing in press, and even accompanying Warner Bros. Japan at Anime Expo. What capabilities does COVER have to facilitate such a wide involvement in the anime industry for its talents?Managing the opening and ending themes for TV anime is quite challenging, but we’ve been able to accomplish it with the support of the music labels associated with each talent. Moving forward, we aim to achieve this independently.
>hololive DEV_IS was introduced in 2023 as a new branch that focuses on music. What do you see as the driving force of hololive DEV_IS and ReGloss? How would you describe them to new viewers?hololive DEV_IS is not a group focused solely on music, but rather a group that aims to explore new frontiers. We hope fans will support their journey as they take on these new challenges. Previously, hololive’s music efforts have centered around solo artists like Hoshimachi Suisei and Mori Calliope. With ReGLOSS, we plan to expand into a new dimension by focusing on music as a unit.
