That’s a legit question.

It’s an OVA film for an anime series (not hentai) about the spirits of things that people fear being able to possess/inhabit human beings and turn them into crazy looking monsters (ala Spider-Man’s Venom) as the action calls for it. This trope is pretty hot in anime right now (see Dan Da Dan, Jujitsu Kaisen, Kaiju #7, etc).

I considered whether to even post this one as it seems to break the trailer format a bit, forgoing the preview of what story is being told and instead just presenting some contextual clues that existing fans will recognize and a ton of mind boggling editing. The trailer for Mononoke the movie was very similar (and, coincidentally, one of the most gruelingly frenetic movies I’ve seen in a long time, and not in an enjoyable way).

So it’s a TV show movie. The creators may have decided to disregard the interest of non-fans when they put this together, which really makes it borderline of-interest to a general audience. In the end, it does legitimately look neat, so I figured why not?
