Gate: Jieitai Kanochi nite, Kaku Tatakaeri Fanservice Review Episodes 01 – 06

The good news is that if you have to have nudity for Gate, you can get it.  Just not from the anime.  At least not so far.  For that you’ll need to check out the manga and/or Satoru SAO’s original artwork.  And fanart, of course.  But ironically, the anime does have small bits of fanservice that weren’t in the manga.
