Morioka Moriko is the main protagonist of the story. A 30-year old single female. After graduating college, she worked in the sales department for the company when she was 24 years old, then later, she decided to quit and become a NEET. She spends her days in a net game in search for the satisfaction that otherwise she can't obtain in real life.

Moriko is a 30-year old female of medium height with waist-length bluish-purple hair that is seen tied up in various episodes and eyes that match, but it is in a lighter shade. Her skin is a bit pale, a distinctive mole near her mouth and her body is an average build.

She does not seem to know or even care about her looks outside her job, and after quitting Moriko's appearance became unkempt, her hair being long and at times unkept, bags under her eyes as well as eyebrows that haven't been tended too.

However, after setting up plans to meet Homare Koiwai for drinks in episode 5, she seeks advice from Lily on how she should dress and style her hair, during which Lily and Kanbe get into a disagreement on if short or long hair is better before Moriko finally chose medium-length hair.

In the manga, she is noted to be very attractive and beautiful among her formerly male co-workers or public.
