"I’m so excited to join this organisation. I’m very thankful for everyone who made this possible and I’m looking forward to meeting all of the players, staff and fans, as well as winning with this team,” Hayashi said in a statement.

Hayashi led the Young Nadeshiko to the 2023 U-19 Sud Ladies Cup and runners-up finishes in both the FIFA U-20 Women’s World Cup 2024 and AFC U20 Women's Asian Cup™ Uzbekistan 2024.

The Hyogo, Japan, native is no stranger to playing in the United States, competing collegiately with the Santa Clara University Broncos in 2024.

In her freshman season at Santa Clara, Hayashi started in all nine of her appearances for the Broncos, recording 10 shots across 719 minutes played.
