Associated tropes:
- Animation Bump: They were considerd one of the better studios out there during their heyday. Roujin Z and Robot Carnival especially stand out with their quality.
- How the Mighty Have Fallen: Originally a producer of several notable OVA titles. After the failure of the Phantom Blood movie, they've since exclusively served as an animation subcontractor (usually on in-between frames) and episode producer until its dissolution on 31 July 2021, after Nomura died on 10 June.
