Akamatsu writes tragedies as well. Yes, I'm aware she liked Takahata, but this boobalicious babe should've been property of Negi, I don't care how it has to happen. maybe Takahata dies and someone feels bad about her grief and forces an eternal love potion in her mouth and she sees Negi-sensei first thing when she wakes up.

Having a child teacher is a funny concept, but the fact this nurse/counselor or whatever she was got away without being filled with the burning desire to be his bang maid was a calamity.
