A particularly hot girl. She is know as a perfect girl, you get attracted by the looks but you stay for her sweetness; above all she's a nice girl who would never let het friends down, always listens and help those who ask for it. She is easy to fall in love with, but difficult to fall out of love with. She doesn't need anyone but herself to help her on her way. She is wild, fun, and a great friend. Yafu is the most amazing girl you'll ever meet, she has an incredible smile that willlight a room and always knows what to say when you're feeling down. She may not think she's perfect but she is perfect and truly amazing and anyone would be lucky to have her in their life. She knows how to make everyone laugh and when your with her you and everyone else, always have a good time
