I dug through the usual places to clear up the confusion: 'Absolute Hypnosis in Another World' is a title that often pops up as an English fan-translation name rather than a widely published official English light novel. That alone causes a lot of mixed info online — forums and scanlation sites will sometimes list different names, translators, or even no clear author at all. What I found most often is that the English title is used for convenience, while the original work tends to be listed under a Japanese or Chinese title on the source site (web novel platforms are where many of these start). Because of that, the credited author in English listings is frequently just the pen name used on the web novel host or the translator who brought it to English readers, which is why name confusion happens a lot.
If you want to track down the official author for the original-language release, the best move is to locate the original web novel or publisher page. Check Shōsetsuka ni Narō (for Japanese web novels) or the major Chinese web-novel hosts if it might be a CN work — the original page will show the author/pen-name clearly. For print editions: the publisher page (like KADOKAWA, Hobby Japan, Tokuma, etc. for Japan) and retailer product listings (Amazon.jp, BookWalker) will always list the official author and illustrator credits. Translators and scanlators sometimes list only their own name on the English thread, which is why a lot of English results don’t clearly show the original author.
From my searches and what’s been circulating in communities, there isn’t a single, universally-agreed English bibliographic entry for 'Absolute Hypnosis in Another World' — it’s treated more like a fan-translated title. So if you see different names floating around, it’s usually because some sites credit the translator/scanner while others try to infer the original author from a translated blurb. Also keep an eye out for slightly different English titles — this one gets rendered a few ways in English, and that multiplies the noise. If you do find an ISBN or a publisher listing, that’s the clearest proof of an official author credit; otherwise you’re probably dealing with a web novel page where the pen name is the only reliable author tag.
Personally, I love tracing these things back to their source — it feels like detective work and it often uncovers neat extras (author notes, side stories, and artwork) on the original pages. If you’re trying to cite the author somewhere, I’d trust the original posting page or the publisher product page above forum posts or scanlation threads. Anyway, hunting down the original author ended up being a fun little rabbit hole for me — even when the trail leads to a pen name, that pen name is the author credit we should respect, and sometimes that mystery is part of the charm.
