Despite her annoyance with Konata's constant references to her otaku interests, Kagami is quite knowledgeable with anime and games, preferring light novels over manga. She tends to fret about her weight even though she has no willpower in controlling her eating habits. Although she and Konata are often seen arguing, Kagami has a strong attachment to Konata and is almost always willing do favors for her.
Cosplayer Kanda Midori makes a great Kagamin! This Miko outfit really suits her character as well. I don’t remember an episode from the series showing Kagami as a shrine maiden though, do you? Thanks to Wendy for suggesting this!
