I'm watching a couple of the anime from the 2015 Summer lineup! Chaos Dragon, Gate, Rokka no Yuusha, Overlord, and Charlotte. They're all pretty great so far, but Overlord is the best one in my opinion. I absolutely love it and I wish the episodes came out quicker, lol. Possibly the best anime of this season, imo.
I'm also finishing up watching Shiki in between releases of episodes in those anime.
