In 2009, the character received a dedicated 5-episode adult OVA spin-off titled (also widely translated from Japanese as Hell Knight Ingrid or Makai Kishi Ingrid ).
The 5-episode adaptation produced by studio Pixy remains the primary source for her uncensored dark-fantasy narrative.
Many appreciate it as a hallmark of late-2000s hentai. Reviewers praise its "very good animation scenes," "old-anime, retro style," and a story that "doesn't feel rushed," with "good character designs".
