A-Cup Angst: She is very, very sensitive about her cup size, which often leads to her butting heads with the well-endowed Misaki.Although the audience can't see, Kuroko mentioned that she had never seen that expression on her face before. In the epilogue of the Sisters Arc, after she fails to give him her homemade cookies, she once again insists on him using her real name, to which he finally does indeed say it.

Accidental Misnaming: Is rather annoyed that Touma keeps calling her 'Biri-Biri' and kept telling him it's not her name.
