mami hiyama

Mami is very aggressive, she is shown to do anything in order to achieve her goal of "avenging" her brother. However, she is also very intelligent, and easily capable of deception. Mami had the intellect to create the Killer Droid, as well as to trick Gardyne and Bishop into believing she was her deceased brother

During the finale of the Paradise Arc, Mami is shown to be mentally unstable. She claims that her only goal in life was to live out her brother's will by destroying/taking over the Earth. Once she is defeated, she actually tries to commit suicide, unable to deal with the fact that her ideology and perception of her own brother was, in fact, flawed.

Her methods of attempting vary depending on which iteration of the series the viewer has watched: the anime showcases her attempting to detonate a bomb, while the game shows a scene in which Mami points a gun at her own head.

In both versions she is saved due to the quick thinking of Hanasaki Ran, who kicks both objects out of Mami's hands before they can be used.
