Background
Enix was a Japanese company that produced video games, anime and manga. The company was founded in 1975 by Yashuiro Fukushima as Eidansha Boshu Service Center, but then it was renamed Enix in 1982. The company's name is a play between the words "phoenix" and "ENIAC" (the world's first computer). The company is best known for the Dragon Quest series. In 2003, they merged with Square to form Square Enix.
