Michishige Sayumi will be appearing in Yoshinoya's PR event on February the 1st in Yoshinoya's Shinagawa-ku store. She will be working as a shop manager from 8:15~10:00 am. Special seats reservation for fans is limited to 20 people, deadline for application is 1/29
The folks over in 2ch (Sayudon Popularization Committee thread to be precise
