月刊少年Ace
"Neon Genesis Evangelion" was created after a meeting between Hideaki Anno and King Records. Although the anime series was conceived before the manga, due to production delays the manga was released first, in the third issue of Kadokawa Shoten's "Monthly Shōnen Ace" on December 26, 1994, to spread public interest in the upcoming TV series while it was still under production. Due to severe production delays, the anime ultimately aired a full 10 months after the manga first appeared in "Shōnen Ace".
