Midnight

Appearance

Nemuri was a tall and beautiful woman with a slender body and blue eyes, framed by long eyelashes. Her hair was a straight uneven dark purple with small sprouts at the ends that reached below her waist. He also had somewhat tanned skin with a mole under his left eye, as well as long red-painted nails. Her hero costume was similar to a dominatrix style one. She was wearing a type of corset that covers only below her breasts over a skin-colored leotard, highlighting her breasts and legs. She was wearing a mask, handcuffs on each wrist, a tool belt on her hips, and high-heeled leather shoes with semi-transparent stockings. She was often seen carrying a whip (not always the same one). During her years at the UA Academy her outfit was much more revealing. He was wearing only underwear that had around his waist a utility belt that also held his Whip. He had around his body a high-collared coat with a dog-like collar and pointed glasses.

Personality

She was a very flirtatious and playful woman, but also had a tendency to lose control in certain situations, such as when she was interrupted or when someone mentioned her age. She didn't mind dressing or acting sexually in front of students and liked having people's attention and stares. She seemed to act on mere whims at times, as seen when she agreed to Mashirao Ojiro and Nirengeki Shoda's request to forgo the event just because she liked their reasoning. Midnight was also shown to be sadistic as she sometimes enjoyed seeing fear, such as watching Minoru Mineta run away in fear and enjoyed dominating others. She was impressed with those who resort to genius and strategic plans, as she was surprised that Minoru used tactical thinking to defeat her and was happy when she saw Momo Yaoyorozu's plan and leadership strategy during their battle against Class 1-B. Despite her flirtatious personality, Midnight was intelligent and perceptive. When interviewed, she also explained that some Hero Suits can be revealing in order to facilitate the use of the user's Quirk and would become serious in necessary situations such as in Izuku Midoriya and Shoto Tororoki's fight where she tried to act quickly knowing that it could be dangerous for their bodies. She was also very enthusiastic when it came to helping her students. When they had to choose their hero name, Midnight happily went to help them and gave them several tips on what it means to decide on a name and the responsibility that it entails.

Quirk (Don)

The power of his Quirk allowed him to put people to sleep instantly, induced by the scent of his body, as shown when he ripped his own suit around his left arm to activate his Quirk in order to stop Katsuki Bakugo. As described, this scent was more effective on men than women, giving its user a huge advantage against them.
