This is the show that got me into anime. Starts off as a pretty happy story but then turns the tables into this morbid, dark, twisted, depressing tale of a young boys adventure to save a girl he just met briefly. No lose ends are left in this show. It pretty much ties everything up at the end. Its real fulfilling yet saddening at the same time. This show puts the horrors of war in the limelight. The decisions the characters make will greatly affect their future and the outcome of their story. Its an amazing show. Give it a shot! You won't be disappointed.
