Characters

 * Billy (ビリー Billy): the main protagonist of the series. He is a small bird who resembles both a duckling and a male cockatiel. He lives with a friendly bear named Brandon who acts as a sort of father figure to Billy. Billy does not speak; instead he chirps, leaving his listeners very confused. Eggbo is able to understand him somehow. His chirps are provided by seiyū Rikako Aikawa.
 * Eggbo (エッグボ Eggbo): the secondary protagonist of the series. He is one of the guards of Miracle Castle, protecting Daniella and Nick, although they can protect themselves quite easily. Eggbo, on the other hand, tends to act more like a coward and will usually make Billy handle a situation that Eggbo couldn't. Voiced by Niki Yang in English and Tarako Isono in Japanese.
