Gammon
A red-haired Solver known as "Galileo," Gammon is driven by money and treasure above all else. He's constantly trying to outpace Kaito to snag the legendary prizes the POG supposedly dangles in front of them. He's got an obvious crush on Nonoha—so obvious he once entered a cross-dressing contest just to impress her with his feminine side.
Gammon and Kaito have a fierce competitive rivalry. He regularly calls Kaito "Bakaito" (a play on his name and the Japanese word for idiot), and the two share more in common than either probably wants to admit: both are hot-headed and stubborn. Fans often note their dynamic carries as much camaraderie as genuine antagonism.
His whole vibe leans delinquent—leather jacket, leather pants, a shaggy hairstyle, and a motorcycle to complete the picture. He talks rough and acts tougher, though his occasional desperation to prove himself or win Nonoha's attention undercuts the tough-guy act.
The name Gammon comes from the board game Backgammon.
