[2] She graduated from Renaissance Osaka High School in 2024, before enrolling at Doshisha University's Faculty of Sport and Health Sciences.

[9] In early 2023, Shimizu decided to spectate a pair skating tryout that had been organized by Bruno Marcotte to help fellow Kinoshita Academy skater, Lucas Tsuyoshi Honda, find a partner.

[13][14][15] Upon partnering with Honda, Shimizu changed her affiliation from the Osaka Skate Club to the Kinoshita Academy.

[19] In late November, the pair competed at the 2024–25 Japan Junior Championships, where they won the national title for a second consecutive time.

[20] Going on to compete at the Junior Grand Prix Final, Shimizu/Honda scored personal bests in all three competition segments and finished fifth overall.

During their free skate, the pair stopped the performance after Shimizu dislocated her left shoulder following a fall during their attempted side-by-side jump combination.

[1][22] Shimizu/Honda were also named to the World team on the condition that they could achieve the mininum technical element scores to compete at the event.
