These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Due to a notoriously mistranslated subtitled version of the 1972 anime, DEBIRU-Man has become a popular nickname for the title character.
Fridge Horror: In Devilman Grimoire, actually. Remember how, in the original Devilman, Miki and Tare were horribly murdered by a psychotic lynch mob consisting of their own neighbours, because they thought she was a witch? When one considers that the cast is pretty much the same in Grimoire (with a few additions), it stands to reason that the Makimuras' neighbours most likely are also the same people. Which then leads to the realisation that the whole neighbourhood is a ticking time bomb, ready to go off under the right conditions. It doesn't help that Miki goes around announcing to anyone who's willing to listen that she is a witch.
Then again, as of the latest chapters in Grimoire, Miki herself is now a Devilman, so killing her just became that much more difficult.
