Kyrou started his junior career off in the 2019–20 OHL season, playing for the Erie Otters, where he would stay for around two more seasons. At some point in the 2022–23 season, Kyrou would transfer to Sarnia Sting, and in the 2023–24 season, Kyrou went to play on the Texas Stars team, leaving the OHL and moving into the AHL.
On October 30th, 2022, while playing for the Erie Otters, Kyrou scored his first hat trick in his career, against the Kitchener Rangers.
In his Sting season, he was dubbed the Cogeco OHL Player of the Week by the Ontario Hockey League for his game-winning goal and assist, sending the team into the 2023 OHL playoffs; for his contributions in their game they won against the London Knights; and for scoring the goal that won their match against the Windsor Spitfires. He was also chosen as an Ontario Hockey League all-star during his time at Sting.
One month into the 2025–26 season, on October 30, 2025, the Stars traded Kyrou to the Philadelphia Flyers in exchange for Samu Tuomaala. Following the season, he was not tendered a qualifying offer by the Flyers, making him an unrestricted free agent. On July 1, 2026, he signed a one-year, two-way contract with the Ottawa Senators. He was placed on waivers by the Senators at the end of training camp and after going unclaimed, was assigned to Ottawa's AHL affiliate, the Belleville Senators, to start the 2026–27 season.
