Kevin Day

Appearance: Blonde hair, 152 cm tall, hazel eyes, pale skin. He is almost indistinguishable from his twin brother, Andrew, but Aaron lacks Andrew's distinctive black armbands. Only Renee, Caitlin, and Neil are able to tell the twins apart when they switch places.

Character: Withdrawn and reserved, he prefers to keep his emotions and thoughts to himself, making him introverted and sometimes distant from the team.

Irritable and sarcastic, especially when communicating with Andrew, with whom he has a complex, mutually resentful relationship.

He strives for a “normal” life: he studies well at the medical faculty, dreams of becoming a doctor, and tries to distance himself from the dark world of his brother and his circle.

He doesn't share Exie's obsession - he plays more out of necessity, fulfilling the terms of Andrew's deal with Coach Wymack.

Struggles with inner demons: feelings of inferiority compared to his brother, resentment towards his mother, and a difficult childhood

Character: Exy's obsession. Kevin is so immersed in the sport that after an injury, he retrained himself to play right-handed.

High standards. Anyone who doesn't meet his standards and lacks sufficient talent is considered a "waste of oxygen."

Harsh criticism. Often harshly criticizes fellow players, which irritates them.

He's reserved in his emotions. He rarely smiles, except in public. His real smile is described as bitter and fragile. Because of this, he's often perceived as arrogant.

Traumatic past. Likely suffers from anxiety and post-traumatic stress disorder due to his difficult upbringing in the Moriyama clan. Unable to cope with problems in a healthy way and prone to breakdowns.

Appearance: Dark hair and green eyes.

Height approximately 185-190 He originally had a tattoo of the number 2 on his left cheekbone. As a child, he drew it with a permanent marker, and later covered it with a queen chess piece—symbolizing that, despite its lesser "importance" compared to the king (Riko Moriyama), the queen is the most dangerous and powerful piece.

Scars from a fracture are visible on the left arm.
