Darker Than Black 2, heck yes.
A Certain Scientific Railgun, heck yes squared.
Kimi ni Todoke, heck yes cubed then powered to the fourth, then multiplied by zero, then added by 9001.
The funny thing is that they're clustered together for my convenience.
And maybe I'll watch Fairy Tail, I kinda lost interest in the manga. Dunno if I'll keep up with the anime.
