Simon is a young boy with red hair and green eyes. His hair is medium-length and wavy, and his eyebrows are cut short and pointing inwards. He wears a purple jacket with white and magenta designs, much like his hair color.

He wears blue shoes with a white insert, a violet toge, and white and violet shoe covers.

Official Bio

A rich B-Shot from a wealthy family who belongs to the East Block.

His B-Daman is the rapid-fire type Lightning Scorpio.

Proud and arrogant, he sees Riki as a rival and is constantly coming up with devious tricks and tactics. However, he is really an endearing character who is also very shy.


Katsumiya is a cheeky person, that sometimes overestimates his own ability, and it is shown that he does not work well with female characters, due to gynophobia, which means that he is afraid of girls. He always dislikes the idea of friends, believes that winning is everything, like Gunnos in Battle B-Daman: Fire Spirts! He believes that B-Daman are merely tools to achieve victory also. He also always argues with Misuru in B-Daman Fireblast.

B-Daman Crossfire

Episode 1

Simon debuted in B-Daman Crossfire within the secret B-Daman training facility. He is first seen among the other facility members welcoming Riki Ryugasaki. During the testing Simon is the first to get a perfect score on stage 2. He is also seen laughing the hardest when Riki fails the test and receives a D ranking.

Episode 2

Simon returns during another Cross Fight Challenge but fails to make the top three ranking. This ignites a jealous side within Simon against Riki.


  • The reason for Simon's Gynephobia (fear of girls) could be attributed to that scene with his family at the finale of B-Daman Fireblast. Therein, the androgynous Simon is being chased by his sisters so that they can give him a makeover and make him dress up as a girl.
  • Simon share the same voice actor (in Fireblast) with Gao Mikado from Future Card Buddyfight.
