I probably would have too if I saw it there lol.
Amazon actually has it for 25 bucks though :)
All repurposed, including and especially the Bloodborne cosplay. If you're interested in the concept art for these games, here's a link for the art book for Horizon and NieR.
The Kat render is from the PlayStation Vita, I believe it was a golf game she appeared in.
Here's the ones I've either bought or want. They're all official:
Grimoire Nier (Japanese only). There's fan translations on the web of this: https://www.amazon.com/GRIMOIRE-Project-Gestalt-Replicant-Japanese/dp/4048686712/
Drakengard 3 art book and guide (Japanese only). https://www.amazon.com/dp/4048660861/
Nier Automata world guide volume 1 (English). I suppose there might be a volume 2 coming in the future: https://www.amazon.com/NieR-Automata-World-Guide-1/dp/150671031X/
And for the poorly-translated novels. Get only if you're not irritated by bad sentence structure, typos, and translation errors.
Of course! https://www.amazon.com/dp/150671031X/ref=cm_sw_r_cp_api_i_NCorDb66FVQBG
