EIM

EIM Ltd. (allegedly meaning "Entertainment Imagination and Magnificence") was a game development company started by Kenji Eno (飯野賢治) after leaving Interlink. Frustrated with having to make games with licensed characters, he eventually shut it down. He would later reemerge with another company called Warp. [1]
