Miina Tsuji Feature | IDEA POCKET's FIRST IMPRESSION 191 Otaku Rookie

“The Next Idol I Found to Stan Was Myself”

March 2026. Miina Tsuji arrived as the 191st installment of IDEA POCKET’s running rookie project FIRST IMPRESSION. The official synopsis of her debut sums up the pitch in a single line: “The next idol to stan, for a girl whose only reason for living was supporting her oshi, turned out to be herself.”

The synopsis opens with bullet-point profile data. From Fukuoka Prefecture, 22 years old. Hobbies: collecting oshi merchandise and going to idol concerts. In other words, a hardcore idol otaku. Then the line: “and yet a beauty like this, packing a G-cup.” A girl who looks like she should be lining up at the merch table — overnight, on the other side of the worship.

Six titles in three months since debut. All five of the AV main features carry an otaku setup in the title. Not a one-off gimmick, but a serialized character. That commitment explains where this rookie stands better than anything else.

Profile

• Stage name: Miina Tsuji (Tsuji Miina)

Height and three sizes have not been disclosed. Ahead of the numbers comes the phrase “an approachability even otaku can reach.” Agency is Y’s Entertainment. Both her X and Instagram bios carry the identical line: “IDEA POCKET exclusive, Y’s Entertainment, 2026.03.10〜.”

Three On-Record Quotes

No interview articles exist yet for a rookie three months in. Instead, three statements from the performer are embedded in the official synopsis of her debut.

“I’m kind of hoping that if I get famous through AV, I might get to meet my oshi lol”

“Sex is just about as much fun as oshi-katsu (blush)”

“It’s embarrassing but I cum right away”

(FANZA official synopsis, March 2026 release)

The first line is the core of what makes her interesting. The motive for stepping into AV is “to meet my oshi.” The otaku logic runs all the way through to the reason for debut. The label did not let this material slip, and every subsequent project was built on an otaku setup.

Monthly Pace, Five Straight Otaku Setups

From the March debut to the announced July release, one title per month. Lined up in order, the blueprint becomes visible.

March: debut as the female otaku you’d see at a live venue. April: follow-up climax assault that buckles legs. May: a celibacy project banning oshi-katsu and sex for a month. June: an after-the-concert downpour that strands her in a hotel room with otaku friends. July (announced): chikan during a live show. The stage never moves more than a step from the concert venue.

The distribution of genre tags is just as consistent. Across six titles, big-tits appears on five, acme/orgasm on four, squirting on three. “Approachable looks × unexpected sensitivity” — the selling angle reads straight off the tag counts. Every title is 4K, exclusive distribution; treatment as an exclusive rookie has been at or above standard from month one.

The director handles the first four titles consecutively — Mametaro Mamezawa — before handing off to Nikuson on the July release. The same director hardens the rookie’s character, then a different sensibility takes over once the train is on the rails. The label’s development pipeline can be read straight off the credits.

Debut (March 2026, 188 min)

FIRST IMPRESSION is the running rookie-debut project IDEA POCKET has used continuously. Miina Tsuji’s number is 191. To the latest entry in a slot that has run for nearly a quarter-century, a long subtitle was attached: “the approachable, cute female idol otaku that fellow otaku want to connect with, the one you spot at the live venue.”

18 reviews, 3.83 average. At 188 minutes, the runtime sits on the long end even by exclusive-rookie debut standards. The synopsis weaves in the surprise framing of “a female otaku whose life was nothing but supporting her oshi, now in the AV industry of all things!” alongside the three on-record quotes.

An approachable, cute female idol otaku within otaku reach (omitted) — the undeveloped sexual potential of a girl who spent her youth on oshi-katsu hits a complete victory! From the debut itself she shudders to climax and cums again and again.

(FANZA official synopsis, March 2026 release)

True to the phrase “undeveloped sexual potential,” the spine of the film is the responsiveness — convulsive climaxes pouring out from the very first shoot. The FIRST IMPRESSION number is 191. Logged as the latest entry in the rookie project IDEA POCKET has run for almost 30 years.

Second Title: “Follow-Up Climax” (April 2026, 124 min)

The synopsis opens with the line “Miina Tsuji has been wrecked!!!” The main feature is structured in six chapters, with the corner names listed in the synopsis in numbered form.

(1) Follow-up piston that won’t stop no matter how many times she cums (2) Huge-cock drill fuck, arching-back climax sex (3) Fellatio VS cunnilingus, mutual ascent to embarrassment (4) Toy climax while bound and unable to move (5) Twitching, leg-buckling squirting threesome fuck (6) Announcement of the next title — “Beyond Abstinence”

(FANZA official synopsis, April 2026 release)

A design that stress-tests the sensitivity shown in the debut from every angle — follow-up, huge cock, bondage, threesome. The synopsis closes with “Outstanding reactions × outstanding sensitivity × outstanding chemistry — a true sex prodigy!” The interesting part is the sixth corner: the trailer for the next title is folded into the main feature itself. Closer to the cliffhanger structure of a serialized manga. And indeed, the corner name “Beyond Abstinence” carried straight into the title setup of the third release the following month.

Third Title: “Oshi-Katsu × Sex: Double Abstinence” (May 2026, 125 min)

Her highest-rated title so far. 6 reviews, 4.33 average.

For one month, Miina — whose reason for living is oshi-katsu and who loves sex — was forced to give up both. At first she was totally fine, but irritation and frustration began to blend together until her mind and her urges started to come apart. And when the shoot day finally arrived, every bit of pent-up restraint detonated at once, with extraordinary results.

(FANZA official synopsis, May 2026 release)

Celibacy projects are a staple. What this title added to the ban list was oshi-katsu. The character read — that missing concerts hits harder than restraining sex — is baked into the concept itself. The structure of the main feature is also enumerated in the synopsis.

1. Real one-month abstinence documentary in close contact, 2. Libido-maxed Miina VS big-dicked man, 3. Follow-up squirting sex that won’t end no matter how many times she cums, 4. Mean edging tease and toy attack climax, 5. Maximum-climax threesome fuck with repeated convulsive acme

(FANZA official synopsis, May 2026 release)

The one-month observational documentary is placed up front, showing the abstinence process itself. The fusion of premise and performer is the tightest of the first three releases, and the rating responded in kind.

Fourth Title: “Downpour Hotel Room Share” (June 2026, 119 min)

The first drama-style entry. The synopsis reads as the opening script itself.

Heading to an outdoor concert with an idol-fan otaku friend. The two are riding high on the best live ever when a sudden downpour hits. Trains stop, stations overflow with people. Soaked through, the two evacuate to a love hotel. Since he doesn’t see me as a man, and since he’s a virgin, I felt safe teasing him a little — and he took it completely seriously…

(FANZA official synopsis, June 2026 release)

The royal-road flow of “virgin teasing turning into a meltdown.” After running the documentary line through to its sensitivity ceiling, this is the first pivot toward situational pieces. Even here, the concert-return setup is not abandoned. The distance of “the otaku friend sitting next to you” runs in a direct line from the debut tagline “an approachability even otaku can reach.”

July: Director Change and Line Expansion

The fifth title, scheduled for July 10, 2026, marks the first change in direction. The director is Nikuson. The title runs the dark line — a female otaku caught in chikan at a concert, falling into pleasure through confusion, then riding the train every day… Until now everything has been “approachable” and “lovey-dovey”; this is the first step into a setup with shadow.

The concert-venue stage remains. With the character pinned, the label is entering the phase of testing both bright concepts and dark concepts. A line test four months into debut is also an observation post for the label to decide the next six months. The numbers on this title will swing what comes after her first year.

Three Products Running in Parallel in March

Three weeks after the AV debut, on March 27, 2026, her first photo book “Sweetish” was released by GOT Corporation. Photographed by Tatsuya Hayakawa, A4 format, 96 pages, list price 4,000 yen.

The meaning of this timing is in the reverse-engineering. Shooting, editing, and printing a photo book takes several months. The fact that it hit shelves in late March means a launch including gravure was being assembled before the AV debut was even announced.

Furthermore, in that same March, the image video “ALL NUDE Miina Tsuji” was released on a separate line. Directed by Yusuke Nawamoto — a production team separate from the AV main features. AV, IV, and photo book running in parallel in the debut month tells the volume of preparation the agency and label stacked in advance. The mass of inventory dropped in the first month is not visible from looking only at the one-AV-per-month cadence.

Main SNS Account Currently Banned

The SNS situation is unusual for a rookie. The main X account was opened in October 2025 with 9,319 followers. As of June 2026, however, posts are not displaying, and the bio carries the following line from the performer herself.

Debuted 2026.03.10 ❤︎ IDEA POCKET exclusive, Y’s Entertainment. Sub → @tsujimi_na. June meet-up dates → 3.20.24 💙 Currently banned

(Performer’s X bio, as of June 2026)

A flow of “I’m banned lol” routed into a sub-account and a link-aggregator site. The “June meet-up dates → 3.20.24” in the bio refers to event slots on June 3, 20, and 24. Even with broadcast capped, the in-person event funnel is preserved. Instagram, with 7 posts and roughly 3,000 followers, is still small; for the time being the main battlefield for recognition is the work itself on FANZA.

Reading the Current Numbers

Plotting ratings in order: debut 18 reviews 3.83, second title 7 reviews 3.57, third title 6 reviews 4.33, fourth title still at 1. Total reviews across six works land around 40. The volume is still small; ratings have not yet settled.

A direction is still readable. The numbers dipped on the second title — the hardware-testing project — then climbed to a high on the celibacy piece where character and concept locked in. This performer’s numbers move with the plausibility of the setup, not the spectacle of sensitivity. The pivot to situational lines is, in that sense, a logical course correction.

Within the same IDEA POCKET exclusive roster, the natural-type Ria Aisai is running ahead. Inside the label’s rookie slot, how thick a differentiator “idol otaku” can be developed into will divide Miina Tsuji’s future.

Summary

From supporting to being supported. The setup has not drifted by even a millimeter.

A 22-year-old idol otaku from Fukuoka debuted in March 2026 as the 191st FIRST IMPRESSION. Three months in: five main features, one IV, one photo book. Every concept is built off the single axis of “otaku,” and the monthly cadence continues like a serialized run. Review numbers opened at 18 / 3.83 and climbed to 4.33 by the third release.

The next inflection point is the July director change. With four character-hardening titles in the books, the breadth of direction is what gets tested from here. With the X main account banned as a handicap, how high recognition can be stacked is the open question.

The catalogue is still six works. Right now is one of the few moments when the entire run can be followed start to finish. There are free sample sites out there, but if the work resonates, the choice to buy the legitimate release on FANZA is what becomes the budget for the next project. The performer’s own stated angle — “maybe if I get famous through AV I’ll get to meet my oshi” — runs directly with sales as the tailwind. Supporting a performer the same way they once supported their oshi is one valid form of fandom on offer.
