- "You watch too much anime."
- ―Kagami to Konata
Kagami's physique is average. She has long, light purple hair tied into twin tails with brown ribbons. Unlike Tsukasa, she has sharp violet-blue eyes.
Kagami is the Tsundere in the group and a stereotypical tsukkomi character. She's a bit egotistical, and somewhat weak in common household chores, such as cooking and cleaning, unlike her sister Tsukasa, who excels at cooking.
She can be the straight and intolerant type. However, she is prone to become shy and lonely at times. Kagami is constantly attempting to hide the fact that she has a deep sense of attachment to her friends, especially Konata.
She really does care about Konata, and is almost always willing to go places or do favors for her. Despite this, she seems to take a twisted delight in mocking Konata's smaller-than-average physique, her lack of motivation and her tendency to be a troublemaker, which usually results in Konata becoming very defensive. Kagami is usually annoyed by Konata's constant references to her otaku interests, but usually has an idea on what she is saying. Kagami is always talking about losing unwanted weight, but once she loses a few kilograms she always seems to gain them back again in the blink of an eye because of her eating habits.
Konata always seems to make a joke out of it as well by offering Kagami a pocky stick or teasing her by saying her internal food alarm clock is broken. Kagami likes reading light novels unlike Konata, who is always reading manga. Kagami is a very good team leader and likes to get things done.
Kagami is Tsukasa's older twin sister and is occasionally referred to as "Kagamin" by Konata.

When Kagami was in seventh grade she made it into Ryōō High School and was made the class president in her first year. Kagami always seems to be put in the same class as Misao Kusakabe, and Ayano Minegishi. She has been in the same class as those two since fifth grade. She is always in a different class than Konata and Tsukasa, but she frequently comes to their class during lunch time to eat with them, to the point where she is on a given name basis with their class but not with her own classmates. Kagami is often shown wishing she could be in the same class as Konata. Kagami chose the humanities course in her second year so that she could be with her, but she was separated into a different classroom.
