Seeing the bright smile of Endo-chan, she has a lovely set of "snaggle teeth" much like Naoko Kawai. In America it would be a terrible facial flaw that would demand to be "fixed" (with braces) at a very young age especially if one wanted to be a popular singer but I know in Japan it was considered cute and interesting. I have appreciated this cultural acceptance of flawed teeth in Japan as I have always had flawed teeth as my mom could never afford to get my teeth fixed when they grew in crooked.
