gogo yubari VS. souma mitsuko
gogo yubari is played by chiaki kuriyama, souma mitsuko is played by kou shibasaki
gogo yubari is more well known from her role in kill bill, but apparently kou shibasaki (souma mitsuko) was originally going to play gogo yubari - but couldn't make the dates for filming so gogo yubari was played by chiaki kuriyama instead
song is 'Favourite Game' by The Cardigans (less info)
