Which Studio Produced The Dear Doors Anime Adaptation?

I’m digging through my mental library and a few sites I usually check, and I can’t find an anime titled exactly 'dear doors' as of the last I looked. That made me pause — did you mean a different but similar-sounding title? Sometimes small typos or regional naming differences hide what we actually mean. For instance, people sometimes mix up 'DearS' (an older early-2000s show) or type phonetically similar names that actually point to something like 'Dorohedoro'. If you meant 'Dorohedoro', that one was animated by MAPPA and is easy to track down. If it’s actually 'DearS' you meant, tell me and I’ll pull up the specific studio credits for that exact release — older series sometimes have confusing production histories or multiple studio credits depending on re-releases.

If you’re trying to verify a studio for a series you stumbled on, here’s the quick routine I use when I can’t immediately remember: check the show’s official Japanese website or the distributor’s press page — they nearly always list the animation studio in credits. MyAnimeList and Anime News Network have reliable staff-and-studio listings too, and streaming platforms like Crunchyroll, Netflix, or Hulu often show production studios on the show’s info page. For physical media buffs, the Blu-ray/DVD jacket will have the studio listed in the credits block. If you have a screenshot of the end credits or opening sequence, that usually names the studio right away, and I’m more than happy to take a look if you paste one.

I get why this is bugging you — I once chased down who animated a very obscure late-night OVA because the art style reminded me of several studios, and it took me a weekend of cross-checking staff names to be certain. It felt great when I finally confirmed it. So if you can give me any extra detail — like a character name, a plot blurb, where you saw the title (Twitter, a fan sub, a streaming service), or even the year it popped up — I’ll narrow it down fast and tell you exactly which studio handled the adaptation, plus any interesting tidbits about the staff or where else their work shows up. Which way do you want to go — should I dig into 'DearS', check 'Dorohedoro', or wait for a bit more context from you?
