A girl who loves manga, anime, and games. Because of this, her thought patterns are heavily influenced by the works she likes. She possesses high athletic ability but is an indoor type who never puts those skills to use.

Tsukasa's older twin sister and Konata's close friend. Since she has a common-sense perspective, she often plays the straight man to Konata's antics. She might be the most sensible person in the group. Once you get close to her, she reveals a compassionate tsundere side.

Kagami's younger twin sister and Konata's close friend. She has a tolerant heart that lets Konata's jokes slide—or perhaps she's just drifting along with the atmosphere. A typical good-natured, healing-type character. Is she actually a mayo-lover?

Konata and the others' classmate. A beautiful, high-achieving, and well-mannered honor student, but also a bit of a space cadet. She became close with Kagami through their roles as class representatives, and eventually became friends with everyone. A perfect human and a walking moe trope.

The homeroom teacher for Konata's class. The kind of friendly teacher found in any school. She has a carefree and somewhat irresponsible personality. She and Konata are close enough to frequently lend and borrow games from each other. She teaches world history. She feels a one-sided sense of kinship with Yui Narumi.
