He spent the 2021/22 season on loan with Belgian first division side Royal Union Saint-Gilloise, linking up with the Brussels based side after a break following the Olympics in Tokyo. 

Kaoru was part of the squad which missed out on bronze in their final match against Mexico, after a good tournament on home soil. 

The 25-year-old has represented his country at senior level, making his debut in November 2021. 

His season with Union was a success as well, as he made 29 appearances, scoring eight times and laying on four assists.

Kaoru would quickly establish himself as a popular player with his exciting displays down the flank, before scoring his first goal in a 3-2 win at Wolves in November 2022.
