So basically I'm with the people that one of the titular characters keeps playing such a background role. We know more about MC's family and overall extended family situation then Rabbit girls anything. She should be a secondary main character at worst, not background mob character like she currently is.
Also Was this chapter needed as a full chapter? Could have been conveyed in 3 panels. Whats worse is the timeskip here is tiny and they look the same and nothing outside of some magic learning has happened.
