I usually watch 20+ series each season and this will be no different. The most notables for me are:
Date a Live: As a light novel reader I am super excited for this.
Railgun S: This will be great assuming nothing gets changed.
Devil Survivor 2: Haven't played the game but a huge fan of SMT, plus Kamiyan so why not?
Hyakka Ryouran S2: More samurai girls is never a problem.
Haiyore Nyaruko-san W: More Nyaruko is enough to get me excited.
My dark horse for the season is:
Hataraku Maou-sama!: This seems fun so this could be my GJ-Bu in terms of surprises.
