Aona Day (Japanese: 御代アオナ, Godai Aona Aona Godai) is a character appearing in the anime series, B-Daman Fireblast. She is Kamon and Roma's older sister, and Greg and Himiko's daughter and eldest child.


Aona appears to a little taller than Kamon but shorter then Roma despite being the eldest child among the three, she has dark teal blue colored hair that's appears to be mid-length with pale pink headband and teal eyes. She wears a elbow-length sleeved layered jacket, yellow colored over orange ones and with white collar and laces. Underneath it is a blue dress and a pair of peach red boots.



Since the fateful day when Kamon lost his memories after his defeat at Roma's hands, she took it upon herself to take care of him, not wanting history to repeat itself should her two brothers ever fight again. To this end, she had him work in her self-named restaurant AONA as a waiter and delivery boy while discouraging him from having anything to do with B-Daman.


  • The aspect of Aona taking care of Kamon as she ran her restaurant is a possible reference to Mie Delgado caring for Yamato while running her café.
