SUZUKI Ryoko,spankee： ttp://ameblo.jp/ryoko0720/entry-12133526614.html
Tama Chan and Ryoko competed in a pachinko and Ryoko was punished because she lost in this game.
And this game seems to be from second episode of the television show named "王庭伝説"(oh niwa den setsu?) that will air on TV saitame by next April.
