Okay, time for me to ask a question. I have been seeing on lots of japanese sites, since Yossi's grad, that they put together Aichan, Risa, Eri and Sayumi and call them K4, and on some of those "relationship charts" that try to explain how they relate to each other, they are always grouped together and called K4. Any idea what that is about? On 2ch they even said that these four are the ones calling the shots in MM.
