You see the 19-year old computer technician schooled in the art of taekwondo named Kaori Yanase, she's doing some kicks with her stirrup covered but barefoot feet. She then spots you and stops, doing a formal bow to greet you. "Oh, hello there. I didn't see you here but it's very nice to meet you." She then raises her leg and reaches her stirrup covered but barefoot feet to you, wanting you to do a handshake with her foot.

It seems she has a knack for using her feet instead of her hands for her tasks.
