Yuika Onosaka (小野坂ゆいか): AV Actress Age, Debut and BakoBako Bus Tour 2026

Yuika Onosaka is the newest shape on this site: the freelance newcomer running at high volume almost immediately. IdeaPocket exclusive for 2024, freelance since 2025 at 10–15 shoots a month, and within two years a performer in MOODYZ’s BakoBako Bus Tour — the industry’s most watched ensemble project — which went to #1 on sales. She also wrote erotic manga as a high-schooler.

The short version

2024: the IdeaPocket debut

She debuted in June 2024 as an IdeaPocket exclusive — the Hokuto group’s flagship for promoted exclusives, the same line as Momonga Kana. Her background, per interviews: a high-school art-club member who wrote erotic manga in pencil before watching AV. The “meat-bodied heroine” framing sold the figure, not the backstory.

2025: freelance, at speed

The exclusive run lasted 2024. From 2025 she went freelance, and Monthly FANZA explicitly described her pace as high for the tier: 10–15 shoots a month. The work spread across OPPAI, Venus, Moodyz, Glory Quest, Max-A and Crystal Eizo.

2026: the rankings and the bus tour

• January 2026 — FANZA monthly sales #10
• February 2026 — BakoBako Bus Tour 2026 (MOODYZ) → #1 on FANZA sales
• March 2026 — FANZA rental #6, sales #9
• June 2026 — FANZA sales #5
• May 2026 — moved agency to T-Powers

The BakoBako Bus Tour is MOODYZ’s annual large-cast ensemble project — the one where Waka Misono and Mana Sakura’s generation also appear. Being cast in it, and having it hit #1, is a marker of tier recognition for a performer barely two years in.

What this career means

The freelance tier’s newest high-volume entrant, and the speed at which the tier can promote. Onosaka went exclusive → freelance → BakoBako Bus Tour in under two years, on volume. Against the older freelance stories on this site — Matsumoto’s record, Misono’s run — hers is the first chapter: the tier’s new normal, established almost immediately.
