Gyuuma is a character from the anime Buzzer Beater. He is a nineteen-year-old athlete who plays for the Bulls team in the Cosmic League. As a member of the Goran alien race, Gyuuma stands out in the league due to his exceptional talent and physical prowess.

In the context of the Cosmic League, Gyuuma is considered to be the player closest in skill to the legendary figure Jordan, especially after Jordan announced his impending retirement from professional play. This places Gyuuma in a position of high regard and expectation, as he is seen as a natural successor to the league's most dominant force.

Despite his formidable reputation on the court, Gyuuma possesses a notable psychological vulnerability. He has a specific trauma stemming from an incident where he was pushed or knocked down by another player named Abiru. This event left a deep mental scar, causing Gyuuma to feel nauseous whenever he hears Abiru's name. This weakness is a key aspect of his character, affecting his composure and hinting at a past encounter that profoundly impacted him.
