Mari Nikaido

A witch most famously known as the Witch of Aurora, based off her ancient Aurora attribute. She was formerly a conscript member of Valhalla before becoming the first enrolled witch in the Anti-Magic Academy where she joined the 35th Test Platoon. Mari is a selfless girl whose only reason in joining Valhalla was so that she could safeguard the children she grew up with in an orphanage in the outskirts of town. Her sense of justice is strong but her motivation mostly comes from her affection towards Takeru Kusanagi, often competing with others and complaining how she never gets any of her romantics "flags" raised. However, over time she begins to cherish her teammates as well. Mari's prodigious magic ability makes her fairly confident in her abilities and she carries herself with a proud demeanor. Due to comparatively small chest however, she is frequently teased by her teammates and is at great odds with fellow platoon member Ouka Ootori, who embodies the two things Mari can't stand the most: having a large chest and, more importantly, despising magic.
