Usa-chan (aka Ousi-chan or Bun-Bun) is a pink plush rabbit and one of Honey's possessions. Usa-chan was hand-made by Honey's deceased grandmother, and although it's just a toy, Honey cares for it as if it is alive, talking to it and having it join him for his regular cake indulgences. At times, the expression on its face changes to show emotion.
