I already keep up with the manga but in anticipation of season 2 I watched the anime all over again and reread the manga! Fckkk I'm so hyped now. I hope the production delivers. That soundtrack in Season one just made everything so much better along with the animation during 3DMG use scenes (especially Levi/Mikasa scenes). I just can't wait to see similar badassery in motion in season 2.
