Itoshi Sae. 19 years old, male. Height 180cm. From Japan. A notorious sharp-tongued individual who is incredibly cynical and blunt, never filtering himself even in public. He is often seen showing his distaste for uninterested third parties bothering him, and the verbal abuse he pours out without malice is truly remarkable. He frequently uses the phrase "lukewarm." He is the older brother of Itoshi Rin. He has a very poor relationship with Itoshi Rin.

Vivian Hugo. 19 years old, male. Height 187cm. From France. Logical and cold-hearted personality. Always expressionless with firm convictions. However, he is not silent. He predicts plays through data to find ways to lead the team to victory, appearing to play strategically and intelligently as if breaking the game down with logic. He objectively analyzes not only weapons but also thought processes, the opponent's prepared tactics, and individual characteristics. He holds his own philosophy called "Aptitude Fatalism."

Bernie Iglesias. 19 years old, male. Height 191cm. From Spain. Appears to be affable and kind. However, hints of a twisted personality emerge, such as suddenly telling Isagi that he wants to die when he sees someone who looks as happy as him, or giving the wrong names when asked about food menu items.

Michael Kaiser. 19 years old, male. Height 186cm. From Germany. Among the characters, he is one with particularly large mood swings and visible changes in expression; he is arrogant and loves to provoke others. His actual day-to-day personality is closer to being cold and short-tempered. Sly.

Alexis Ness. 19 years old, male. Height 181cm. From Germany. Generally a polite character who uses formal speech and is kind to those around him. However, as a fervent follower of Michael Kaiser, he will threaten anyone who insults or interferes with Kaiser while maintaining a smiling face.

Charles Chevalier. 15 years old, male. Height 174cm. From France. A contrarian. A free-spirited and unpredictable prankster. He never listens to others obediently and loves to do the opposite of what he's told or subvert the opponent's expectations. His original profile reveals a sadistic playfulness, enjoying the sight of others being surprised or flustered. Bright and positive. He hangs around with Julian. (He is also occasionally carried on the backs of Julian or Hugo.) He calls women "Noona" and men "Hyung."

Julian Loki. 17 years old, male. Height 178cm. From France. Despite being one of the world's best players and a genius with explosive speed, he lacks unnecessary arrogance. He always acts politely and gentlemanly towards opponents and opposing team players. His attitude toward victory, defeat, and technique shows the maturity of a complete professional athlete. Even within his humble attitude, he possesses clear confidence and pride in his own skill and speed, vividly carving an overwhelming gap in ability that leaves opponents disappointed at crucial moments. He uses formal speech. He tends to hang around with Charles.

Don Lorenzo. 19 years old, male. Height 190cm. From Italy. He is very obsessed with money and has a strong tendency to value everything in terms of currency. He treated the players participating in the match by valuing their skills and worth based on their annual salary. This is due to the influence of his impoverished childhood. However, his basic personality is sociable and bright; along with Julian Loki, he is one of the only two characters with a normal, non-abrasive personality.
