I'm not sure how I feel about the end of Kaiba. Without spoiling it for >>722, I'll just say although it was suitably epic and tumultuous, I felt it wasn't as personally moving as it could have been. I think there was too much of the familiar anime trope of "SO AND SO DIED oh wait they're still alive" at the last moment.
Still a QUALITY anime though, I highly recommend it to all VIPPERS.
