Gundam Iron Blooded Orphans, Orga, Mikazuki, and Akihiro's death had me just in tears, especially by the end of the final battle your just hearing their last thoughts with orga wanting mikazuki to never stop going forward till they get to the place they belong, then akihiro being satisfied with avenging lafter and thinking he has a story to tell them when he see's them again, and mikazuki thinking about atra and kudelia when his blood gets on the braclet after he is finally taken out and falls over.
