Well Kawakami's Christmas date doesn't imply something sexual, but as you said it's not really relevant. I can't imagine Futaba has more going on then just spending the night though.
It's hard for me to get over the little sister energy she has. But the non-incestuous kind, unlike Sumire. Kasumi basically getting adopted into the Sakura family over the course of the game is one of the best parts of P5.

Futaba is the orange haired glasses girl. She is 15, although she acts younger due to being a shut-in. Hard to believe Kasumi and her are the same age...
