Moena Shinguuji

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. At first, she is unaware of her dual-life as Angel Blade, until (near the end of the 1st episode) her heart pendant is damaged, leaving Moena's consciousness in control of the Angel Blade body.
