Hyper Speed GranDoll

Hikaru has always believed herself to be just a normal high school girl...well, as normal as a teenager with a genius mad scientist for a father. She spends her time with her best friend, day dreaming about the boy she loves and watching her favoite super hero show. One day, the past that she has knows nothing about comes back to haunt her. She is shocked to learn that she is the last surviving member of royal line from a far away planet. Even more, she finds out that she has been protecting the ultimate armour and that it can decide the fate of the entire galaxy.
