I feel like "oneshot" is a very generous term for what this is - two pages of illustrations with translated notes. not that I don't appreciate it, there's a ton of Japanese artists who draw pictures that I'd like translated, but this feels more like something that should be uploaded to danbooru than mangadex.
On the other hand, if this is just the precursor to a full series, then I totally understand. and obviously I got no qualms about the subject matter itself.
