I was expecting most of the characters to die, but damn if it didn't hurt each time they did. Hush was the only person I was surprised to see die as I thought he was going to become Mikazuki's successor or at least look after everything that Mika left behind. But no, Hush died protecting the evacuation route for the non-combatants of Tekkadan.
Although they didn't get to see it, Orga's, Mika's and everyone's deaths weren't in vain as it caused a massive ripple in the world order and changed things. The Seven Stars disbanded and now a democratic system is in place (Fareed's dream). While Child Soldiers have been outlawed and all the children are slowly being taking in and given a chance at a new life (Tekkadan's dream).
Plus that poetic justice of Ride using Orga's pistol to kill Nobliss for having Orga assassinated. :3
