why back in the day we didn't 'download', we had to swim to japan if we wanted fresh anime and that was only if...

I dream of a better tomorrow... where chickens can cross roads and not have their motives questioned.

OMG I cant believe Ai Kora is ending... so sad.....

Ai Kora ending gives me more incentive to read it since I won't be constantly hanging off a thread waiting for another release. Oh, I wish I could read all of Sola though. That has me hanging on thin threads.
