株式会社レッド・エンタテインメント 制作的 Galgame

Red Entertainment is a video game developer and publisher based in Japan. Originally founded in 1976 as Red Company (though it did not begin doing business until 1985), it was reorganized and succeeded by a new company on December 4, 2000, under its current moniker of Red Entertainment. While Red Company as a public corporation dates back to the mid-1980s, the first title released under the Red Entertainment brand was Gungrave on July 17, 2002. The name "RED" comes from "Royal Emperor Dragon". In 2011, the company was acquired by Chinese game developer UltiZen Games Limited. In 2014, Red Entertainment was sold to Oizumi Corporation.
