One item I had seen very few of at conventions (at least when Mamotte was popular): keychains! I had seen a Tasuke keychain once at Otakon or Katsucon and immediately coveted the elusive Rishu keychain.
These keychains are gashapon. Gashapon items are usually won at random by doing a crane-type game or from a coin vending machine. So getting the ones you want is completely up to chance!
This series has a total of 6 keychains: Rishu, Shaolin, Ruuan, Tasuke, school uniform Shouko and school uniform Shaolin.
