Koharu is unlike Ash and Go, Ash and Go like to capture and battle with Pokèmon; Koharu however gets along well with Yamper but has no interest in catching Pokèmon or Pokèmon battles.
Koharu is often labeled as someone who really loves Pokèmon due to her Father, Professor Sakuragi. A label which bothers Koharu.
Meanwhile a Gengar is causing trouble in Sakuragi’s laboratory. Will they be able to stop Gengar causing trouble?
