Hiyokokko

Serving primarily as a source of comedic relief, this clever little chick possesses the rare ability to speak, though its words remain unintelligible to everyone except Riku. Despite its tiny size, the bird displays surprising intelligence throughout the series. While most characters are oblivious to its chatter, the unique bond between the chick and Riku allows for humorous interactions that drive much of the show's lighthearted energy.
