Ichigo sees Nana and Junna practising with their weapons when she's fairly young and begs them to teach her stuff, because it looks super cool. They put it off until she's a little bit older, but end up going along with it. After all the training, Ichigo's pretty ripped and one day, when at school, she ends up going around sleeveless. Some girl makes a comment about it in Midori's earshot and she's deeply horrified at people being attracted to her older sister. Ends up staring at the dorm wall.
