One

One is a character first appearing in pop'n music Sunny Park. He's a humanoid dog who joined Kivy's band, oni tai Z, after Kivy gave him kibi dango from his confectionery shop. He plays on his signature bone-shaped guitar. He initially appeared in Kivy's Win animation in pop'n music 18 せんごく列伝, though he wasn't named at the time.

He wears gray and brown makeup, a dark gray outfit with black boots, black and brown wristbands, a necklace, and a brown sash with a bone design tied at his waist.
