Moena Shinguuji is a young, not overly developed, student at the academy who is able to transform into her super heroine alter ego, Angel Blade, thanks to the power of her heart-shaped amulet given to her by her parents. She works as a waitress at her aunt's cafe on the academy campus. Moena transforms into Angel Blade - her body grows, into a more adult, developed form with big breasts. She gains a technological uniform that reveals the chest and crotch area, and a red helm with green visor.
