I've finished translating all the chapters released so far, so I'm now beginning typesetting, uploading as I go. Released chapters are as follows:
Ch. 1 - 25 pages
Ch. 1.1 - 3 pages. This was released months before Ch. 1 and was called "Untitled". It's not actually part of the Pixiv album for the series, for some reason. Perhaps so it wouldn't spoil the "reveal" of the pairings before Ch. 1?
Ch. 1.5 - Omake, 7 pages. Omake chapters don't seem to feature the otaku, but otherwise they're just shorter chapters.
Ch. 2 - 25 pages
Ch. 2.5 - Omake, 7 pages
There's been roughly two weeks between each release so far, so Ch. 3 will likely be released soon.
As for this chapter, if you're curious about protruding canines you'll need to search for 'yaeba' or '八重歯' because it doesn't seem to be common outside of Japan. Also, I bet that's what anime girls' "fangs" are.
