It can sound wierd, and not every budy will agre with me but I think this is one the moast lifefull film I ever seen.
Some times it is sinfull like we people are some times, and getting in trubble of that sins. but only the feeling of life when our mind opens up again can safe us an even make us paradoxally greater then we was befor that.
I strongly recomend this anime, an mayby you get something for you too to think about.
(Or my be i am wierd).
