Konata is a mischievous, sarcastic and eccentric, yet good-natured and friendly girl, who is very intelligent but lazy, which is why her grades are uneasy. She always teases her friends in a funny type of way, such as if they like someone. However, unlike Kagami Hiiragi (Konata's friend), Konata is very good at pulling an "all-nighter" and she always crams for tests the night before they happen, instead of studying ahead.

She has a very strong passion for anime, manga and adult video games.
