Shout! Designworks

Shout! Design Works was established in 1992 by Shuho Imai, also known by the alias Akishi Imai, to support his freelance work. Imai previously worked at Atlus as a pixel artist. The company was best known for the Tokyo Majin Gakuen franchise, which came about from Imai's desire to work on an original creative project rather than just contract work.
