So far it's shown that Fumiya's personality is sort of like Suoh's in a way. Normally he's aloof, taunting, flashy and dramatic of his own power; while the other side of him speaks in quite an aggressive and stern tone to even his sister when he gets emotional. He's somewhat over-confident in battle and outside of battle too and also quite standoffish towards the Victories.
- Wizard Fafnir Ratchet Rise Sen: Fumiya's primary Beyblade in Beyblade Burst GT.
- Ratchet Drain: While an opponent attacks Fafnir's disc the Ratchet Disc absorbs the opponent's attack.
- Wizard Blow: When Fafnir lands on the rim of its Rise Performance Tip, it gets a speed boost, allowing it to deal more damage. This is similar to Shu Kurenai's Counter Break.
- Wizard Spin: Like Geist Spin Wizard Fafnir absorbs it opponent's attack and created a miniature Hurricane.

Amane is Fumiya's rival and because he's a member of the Victories, they're also distant to each other.
Ichika is Fumiya's sister. So far in the series, Ichika doesn't believe in all about winning as opposed to Fumiya, straining their relationship.
- According to the manga, Fumiya was inspired by Free De La Hoya's Fafnir bey and, after obtaining his own Fafnir, personalized it to his own style.
- Fumiya is the first character introduced in GT who is left-handed.
