Born in São Paulo, Demethryus passed through Club Athletico Paranaense before landing in Greece with Episkopi, where he impressed enough in the first half of the 2021/22 season for AKFC to swoop for him in January 2022.
With dazzling ability and natural instincts for the game, Demethryus scored 12 goals with 11 assists in 85 total matches across his first two-and-a-half seasons with the club, helping AKFC ultimately win promotion to the Super League in 2023/24.
