Azusa 2

Sidekick to Ayako Mano. She looks very much like Azusa Kanzaki. Since she never mentioned her actual name, Madoka dubs her with the name "Azusa 2." She is very much like Azusa, both in appearance and in skill, which means that she too is a klutz at times and not very skilled in fighting. She does seem to have a bit more experience in combat, although not much of a difference compared to Azusa Kanzaki.
