this anime made me cry, lol. this is the only anime that touches my heart. it's awesome, their bond is their treasure, at first, i didn't expect that this is going to be an epic anime, I thought it was lame and gay, but after the first episode I was totally hooked. I'm not a fan of drama anime, This is the only anime that made me like drama genre. If you haven't watched it yet, go watch it now, it's the best anime I've watched in a long time.
