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 shown to be somewhat over-confident in battle and outside of battle too and also quite stand-offish towards the Victories. It is also shown that he's quite cocky.
- 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 as well as increasing its stamina. This is similar to Silas Karlisle's Roller Drift.
- Wizard Spin:
|Beyblade Burst GT|
|Drum Koryu||03||Win (1-0)|
|Amane Kusaba||03||Win (1-0)|
|Drum Koryu||05-06||Lose (1-2)|
Amane is Fumiya's rival and because he's a member of the Victories, they're also distant to each together.
Ichika is Fumiya's sister. So far in the series Ichika doesn't believe in all about winning, straining their relationships.
- It is unknown of how he got Fafnir, as it was previously owned by Free De La Hoya.
- Fumiya is the first character introduced in GT who is left-handed.
