Club career
Valour FC
On 5 May 2021, Akio signed his first professional contract with Canadian Premier League side Valour FC.[6] On 27 June 2021, he made his debut as a substitute in a 2–0 win over Forge FC.[7] He scored his first professional goal on June 30 in a match against HFX Wanderers. Valour started the season off very strong, aided by home field advantage as the first segment of the season was played only in Winnipeg due to the COVID-19 pandemic. When this part of the season ended, the team began to struggle midway through the season and fell out of a playoff position. However, Akio helped lead a resurgence near the end of the season, pushing Valour right into the thick of the playoff race, with performances such as his two goals and an assist in a crucial match against Cavalry.[8] But despite Akio and the rest of the team's efforts, Valour just missed out of the playoffs.[9] Overall Akio had a strong first professional season, finishing with eight goals and three assists, and was in especially excellent form in October and November, being named in the CPL Team of the Week twice.
In January 2022, Valour announced they had picked up Akio's contract option, keeping him at the club through 2022.[10] He remained a fixture in Valour's starting eleven. During this season he made international headlines in a controversial manor, by accidentally making a goal-line clearance of his own teammate's shot. However, Valour still won the game.[11] This incident did not derail his career, as just a week later he moved up through securing a transfer with Ross County, who had been impressed with his overall play. Akio departed Valour as the club's second highest goalscorer all time, behind Moses Dyer.[12]
Ross County
In July 2022, Scottish Premiership side Ross County announced they had signed Akio from Valour FC on a three-year deal.[13] On his debut against East Fife on July 23 in a Scottish League Cup match, Akio tallied two assists in less than two minutes. Later on in the game, Akio suffered a knee injury for which he underwent surgery for, sidelining him.[14] On September 3, Akio made his league debut for Ross County against Aberdeen where he scored a last minute goal in the 95th minute to secure a point.[15] Akio made his first start for the club on September 17 in an away league match against St Johnstone where they drew 0-0.
Cavalry FC
In July 2023, Akio returned to the Canadian Premier League, joining Cavalry FC for an undisclosed fee,[19][20] signing a contract through the end of the 2025 season with his home-town club.[20][21] Akio would score his first goal for Cavalry in his third game, celebrating by running to the stands to hug his mother.[22] In July 2024 it was announced that Akio would miss the rest of the season due to an ankle injury.[23] After the end of the 2024 season, Cavalry and Akio would mutually agree to terminate his contract, ending his time at the club.[24]
