[8][9] Shortly before the 2015–16 season, Aoki developed spondylolysis following a hard fall on a triple axel attempt in practice.

[5][10] In spite of this, Aoki debuted on the ISU Junior Grand Prix circuit, placing seventh at 2015 JGP Latvia.

[11] Competing at the 2021–22 Japan Championships the following year, Aoki placed thirtieth in the short program and did not advance to the free skate.

In April 2022, she moved from her hometown of Yokohama to Chiba so she could train under Kensuke Nakaniwa, Makoto Nakata, Momoe Naguma, and Aya Tanoue at the MF Skating Academy.

[11] Aoki was invited to make her Grand Prix debut at the 2023 NHK Trophy, where she placed eighth in the short program after receiving three underrotation calls on jumps, though she observed that despite this she landed them "comfortably."

"[14] She went on to finish ninth at the 2023–24 Japan Championships, before closing her season with a silver medal win at the 2024 Challenge Cup.

[7] She then competed at the 2024 NHK Trophy as the host pick, where she gained a new personal best short program score by over eleven points, with 69.78.

[16] Aoki finished fifth in the free skate segment, but her lead from the short program put her third overall with a new personal best total score of 195.07, successfully taking her first Grand Prix medal, and rounding out a Japanese women's podium sweep at the competition alongside Kaori Sakamoto and Mone Chiba.

[17] Following the event, Aoki expressed elation at the result saying, "I competed in the Junior Grand Prix but I never stood on the podium.

"[19] In October 2024, Aoki joined forces with Olympic champion Shizuka Arakawa, Olympic bronze medalist Daisuke Takahashi, Kana Muramoto, Takahito Mura, Kazuki Tomono, Keiji Tanaka, Kosho Oshima, Yuto Kishina and Rena Uezono to launch the members-only official fan community F-Ske on the platform FANICON.
