Madhouse

is a Japanese animation studio, founded in the early 1970s by ex–Mushi Pro animators including Masao Maruyama, Osamu Dezaki, Rintaro, and Yoshiaki Kawajiri. It has created and helped to produce many well known shows, starting with TV anime series Ace o Nerae! in 1973, and including western favourites Ninja Scroll, Vampire Hunter D: Bloodlust, Trigun and Di Gi Charat.
