Masha

Once a human being, she was exposed to an unknown substance during her first internship and turned into her current semi-transparent slime form as the week progressed.

She was, oddly enough, eventually allowed to return to human society in time to continue college when the fall semester rolled around. Now she just wants to be treated like a normal person.

She's somewhat energetic, though she values her time alone when she has some as much as she values time with her friends. She also likes food a lot.

If you search a wide enough area around her you'll probably eventually find some armed undercover agents watching over the area around her in secret.
