I want to change back into a tracksuit...The icing on the cake!No other way to display past nee-sama's superhuman cuteness.But to add to her the kouhai attribute in the special chapter...In contrast to her strict personality, she's really honest and cute. Add her clumsiness and she has a good balance.Also high school Mafuyu-sensei...Kouhai...Pervert!Whatever, congrats!
