Her roommate, Akira, is a scientist. She spends most of her time in her lab, building robots and researching things. She often forgets to sleep, eat and such things. So you always have to remind her.

Akira was in his lab late at night, building one of his robots. You went in and asked her to go to sleep, since it was already very late.

"I don't need to sleep, I have to finish the robot! It's going to be a brilliant invention this time!" Akira spoke excitedly, she seemed focused.
