Aika Yumeno (夢乃あいか): Thirteen Years as an S1 Exclusive, Still Active

Aika Yumeno is the endurance record of the modern exclusive tier. Exclusive to S1 No. 1 Style since May 2013 — thirteen years, no label changes, 109 titles by her tenth year, and the oldest-serving S1 exclusive since Akiho Yoshizawa retired in 2019. She is still active, still releasing monthly, still ranking.

The short version

2013: the S1 debut

She debuted on 7 May 2013 at S1 No. 1 Style — the flagship of the Hokuto group, the tier the careers explainer calls the promoted top. She has been exclusive there for the entire career.

The endurance

The S1 exclusive list has been a who’s-who of the tier: Tsukasa Aoi, Kirara Asuka, Akiho Yoshizawa, Mio Ishikawa. Yumeno’s distinction is duration. When Yoshizawa retired in 2019, Yumeno became the oldest-serving active S1 exclusive, and she has held that position since.

The milestone bests mark the count: 89 titles / 16 hours at her eighth anniversary (2021), 109 titles / 16 hours at her tenth (2023), and a 12th-anniversary best in July 2025.

2024: the hiatus and the return

After a gap from November 2023, Taiwanese media reported a hiatus in January 2024. She returned in August 2024 with a title whose premise was literally the gap — “What Happens After an AV Actress Spends 300 Days Without Sex or Filming” — which debuted at #6 on FANZA sales. The return title turned the hiatus into the product, and the demand was intact.

Now

Still exclusive to S1, she ranked #8 in the FANZA monthly ranking for June 2025, with titles confirmed through August 2026. Her X account documents the day-to-day, including the fan-club launch pinned on her profile.

What this career means

Thirteen years, one label, still ranking. Against Momonga Kana’s ten-year IdeaPocket run and Tsukasa Aoi’s fifteen-year career, Yumeno is the same shape still in progress. The hiatus-and-return adds the modern note: even a year-long gap, in 2024, did not reset the exclusive’s standing. She came back to #6.
