Okay, I dug around my memory and shelves mentally—'Deliria Goddess' isn't a single, famously mainstream title like 'Naruto' or 'One Piece', so it can be a little slippery. From what I can tell, there are a few different pieces of media or fanworks that use that phrasing (or very close variants), which is probably why you're not finding a straightforward author-credit in one place. Sometimes it’s a webcomic or indie novel that uses a pen name and is hosted on a platform rather than printed by a major publisher.
If you want the creator's name, the quickest route is to check the credits on the site where the work is published: official webcomic platforms (Webtoon,
Tapas, Lezhin, Bilibili Comics), self-publishing platforms (RoyalRoad, Wattpad,
webnovel) or ebook storefronts (Amazon/Kindle,
kobo). Look for an author/artist byline, an “About the Author” section, or a publisher imprint. If you find a listing, cross-reference it on cataloging sites like MangaUpdates,
Goodreads, or even the work’s page on a retailer to confirm the creator. For actual reading, favor official releases first—most creators rely on those sales or ad revenue.
Personally, I love tracing obscure titles like this: it turns into a little treasure hunt.
if you tell me where you first saw the name, I could narrow it down faster, but even without that, checking those official platforms usually turns up the creator and the legitimate reading options. Hope you find the exact version you mean—happy hunting!
