Ruka Itoi (糸井瑠花): S1 Debut, kawaii* Transfer, Then Non-Exclusive Work

Ruka Itoi (糸井瑠花) is a Japanese AV actress billed with the agency Esflirt (エスフラート). Her own account dates the start of work to 10 December 2024, announced an S1 exclusive debut, and in February 2026 said the exclusive chapter was ending.

The short version

2024: the education-student debut

On 12 November 2024 Itoi posted that she would make her exclusive debut from S1 under the name 糸井瑠花. Her profile dates the start to 10 December 2024. FANZA’s release post for the debut title, 時代は賢くてエロい娘！若くて綺麗なカラダの教育実習生！糸井瑠花AVデビュー, describes a 22-year-old current university student in an education faculty who was in a teaching practicum. That is a studio marketing frame, not an independently checked school record.

The older page said she entered “for the short term” after giving up a plan to teach. That wording comes from a Japanese Wikipedia summary of an interview this revision could not open, so it is not repeated as fact.

2025: the kawaii* transfer title

On 3 November 2025 the official kawaii* account announced a title explicitly labeled as her kawaii* transfer and first nakadashi-allowed release. The studio’s own title page gives the DVD date as 2 December 2025. That supports a transfer around the end of 2025. It does not support a count of S1 titles, or a claim that exclusivity ended in a particular November release, unless those release lists are checked one by one.

2026: non-exclusive, not a shoot-count claim

On 17 February 2026 Itoi posted that she had become a planning-single actress (企画単体女優), that exclusive titles would end with the late-January release, and that this was the start of a second chapter. That is the checkable contract change. It is not evidence for “8–10 shoots a month,” “about 45 titles,” or a fixed roster of SOD, Fitch, Deep’s, Momotaro and Crystal Eizo. Those figures are removed.

A Weekly Playboy naming as a “next-generation dirty-talk” or “new-generation squirting” actress is also removed. This revision did not find a checkable issue citation for it.

Now

As of 2 October 2026 she was still posting, and an Esflirt-branded public event listing booked her for 3 October 2026 at Lammtarra Epikari Akiba. Active here means publicly scheduled, not a statement about any remaining exclusive contract.

What this career shows

The useful part of the page is the shape of the arc, not a volume ranking. An S1 exclusive announcement, a kawaii* transfer title about a year later, and a performer-announced move to non-exclusive work in February 2026 is a short, sourced timeline. Counts and magazine nicknames can be added back only with a checkable source.
