I've read this manga many, many years ago. I don't remember much other than hot bois. Glad to see it back lmao. I'll enjoy the chaos. I didn't realize it was Yoko Taro before, though. Interesting.
Edit: In regards whether this is related to Yoko Taro's other works, it seems to be so. The scanlator-translator is a hardcore fan of their works and you can see many things in their web/blog like http://nier2.com/kimishini-faq/ interesting to read.
