Aiko Omori is the ultimate Somnologist, which means she studies sleep and sleep patterns. This has made her more used to nocturnal sleeping patterns that humans don’t usually adapt to have. During the day, when Aiko’s gotten used to sleeping, she’s often very tired and sporting a “get-to-the-point” attitude. This is mainly due to a broken sleep schedule, which is very understandable. During the nighttime, she’s very observant and attentive. Her funny sleep schedule also gives her some funny habits that affect the way she looks. She doesn’t eat breakfast, which makes her thin. She’s grown to hate breakfast. As well as that, her rarely sleeping while at Sweet Dreams Academy and struggling to fix her sleep schedule gives her some nasty eyebags and slight fatigue.

Aiko Omori has a slight rasp, lower female voice, and usually sounds half asleep. She sounds kind of monotone, like she doesn't care about anything. That's roughly 75% of her attitude. The other 25%, she sounds like a normal human being with less rasp and more energy, even if her voice is still really low. She needs to be this versatile if you want the role.
