any niche anime recommendations?

shin megami tensei: tokyo revelations and electromagnetic girlfriend are short (like an hour to an hour an a half total) ova's with supernatural and suspenseful elements. tokyo revelations especially is a fever dream but i really enjoyed it and you can watch it here on youtube (the dub has its funny moments, i like it). despite it being related to a game series, you don't really need to have prior knowledge of it. electromagnetic girlfriend has more mystery to it and you can find the first of two episodes also on youtube.
