An assistant to Becky's former mentor who soon joins Class 1-D to keep an eye on her. Often wears a maid outfit.
Not much is known about Media, other than the fact that she always smiles, never seems to open her eyes, and can call upon superhuman strength on occasion. She was first introduced as the assistant to The Professor, Becky's mentor back at MIT. When that arc resolved, Media followed Becky back to Momotsuki Academy and enrolled there.
She hints that she had a relationship with Behoimi at some point in the past, and on occasion tries to convince her to return to her "magical girl" mode. However, Behoimi doesn't feel like playing along.
