Nico Niyama is known as "Screwloose" within the Kizna experiment.

Nico appears to be a generally eccentric, animated, and childish girl. She has a unique sense of style, and she seems to want desperately to stand out. She tends to overreact or be very dramatic when experiencing new things, and presents herself in a very feminine manner. Despite all this, she proves to be rather perceptive and intelligent.

She has a high-pitched, childish voice with a great amount of enthusiasm. However, note that she is a teenager, despite looking young, so please avoid too much of a baby-like demeanor.
