Holy crap, why did I leave this for so long.
I love this, in just one episode I'm hooked.
Don't quit halfway through, the ending is one of the best things in our anime world
Marathon that shit, if you want to feel the full effect. Leave so you don't get spoiled.
One of the best anime of the decade
Now go marathon it
It gets better. I'm going to echo what everyone else said and tell you to go finish it before you have it spoiled for you.
