I've never really thought of Aquamarine's position to be truthfully honest. Some of the things Blood has said has kind of shaped my opinion of her role, that Aquamarine was kind of unusual and looked down upon at HomeWorld. I don't think Aqua was suppose to be a fighter. I think she was made for helping those in Kindergartens understand what they would be, giving them the needed information of their job and healing those in combat. I think this is why Aquamarine is so sensitive when it comes to knowledge or fighting skills being thrown at her because she has come a long way to be where she is and as strong as she is. She literally went against her every being to learn how to fight and the war was just that hair too much, hence why she did fusion so she could be lost and the others would be stronger and have more of a chance at living.
