Hajimete no Dai Keiren Special | Understanding 83 Titles of Numerical Records

Every Record Carries a Name

This series’ titles function like record certificates. The original title from an October 2024 release reads like this: “340 Climaxes! 5,800 Convulsions! 2,900cc Squirt! Gravure Entertainer Kiho Kanematsu Eros Awakening First Great Convulsion Special.” The three numbers opening the title function simultaneously as catalog identifiers.

Every record in this series has a performer behind it. 340 climaxes belongs to Kiho Kanematsu. 6,690 convulsions to Hiyori Nosaka. 10,200cc squirt to Mai Ushio. And the review count record belongs not to a flashy numbers-chasing title but to Uta Hayano’s June 2021 release with 344 reviews. More than double the second-place count, this single title concentrates more discussion than any numerical peak. A sample video would reveal why 344 viewers responded the same way. This title belongs in the entry-points lineup alongside the three record-holders. The series began in 2017 with Yua Mikami, and 83 titles emerged from that starting point.

One other metric exists. The most recent release hit February 7, 2025. For seventeen months, no new titles have dropped. The 83-title shelf is now solidifying. This is the moment to decode it.

Series Identity

S1 No.1 Style (established November 2004) launched this program in March 2017. Yua Mikami headlined the inaugural title. A flagship-tier casting from the outset signaled this was no experimental trial but a marquee program. Since then, nearly every title has adhered to the formula: ”◯ Climaxes! ◯ Convulsions! ◯cc Squirt!” plus actress name plus “Eros Awakening.”

The phrase “Eros Awakening” concentrates the program’s intent: moving debutantes or performers not yet peaked beyond standard shooting territory. The strategy targets women mid-journey, not established icons.

The measurement methodology remains undisclosed. The numbers in titles represent manufacturer claims. Yet because 83 titles follow the same formula consistently, the relative comparisons within the series hold. The range: climaxes from 92 to 340, convulsions from 3,600 to 6,690, squirt volume from 1,300cc to 10,200cc. Eight years produced substantial expansion across every metric.

Three Records, Three Performer Types

Arranging 83 titles’ numerical data reveals performer reaction patterns cluster into three types.

Climax-dominant performers peak with Kiho Kanematsu’s 340 climaxes. Second place: Sakura Kageyama at 251 (2020). Tied at 222 climaxes: Niko Kawagoe (2024) and Miyuu Kohinata under her former name Miyuu Kiyohara (2023). These types compress successive orgasms in tight intervals.

Convulsion-dominant performers peak with Hiyori Nosaka’s 6,690 convulsions in December 2024. Second place: Kozue Fujita at 6,320 (2021), a title that also appended ”& Great Deluge Special” to the standard format. These performers’ bodies continue responding long after climax.

Squirt-volume dominant performers peak with Mai Ushio’s 10,200cc in January 2021 — five 2-liter bottles’ worth in official claims. Three more titles recorded exactly 10,000cc: Izuna Maki (2018), Rikka Inui (2019), and Miru Sakamichi (2020). A distinct numerical tier.

Title opening numbers telegraph each release’s character. A viewer seeking climax frequency versus convulsion intensity versus volume can select from the three-number opening alone. The catalog design makes 83 titles navigable through this taxonomy.

Entry Routes: Six Titles Across Eras

Viewing all 83 without filtering isn’t realistic. Across timeline, performer type, and numerical trajectory, six titles function as entry points to grasp the series’ skeleton.

Origin: Yua Mikami, March 2017

Released March 16, 2017. 92 climaxes, 3,600 convulsions, 2,300cc squirt. The series’ baseline. 92 climaxes became the historical minimum — still the series’ starting point for comparison.

Yua Mikami: branded the “national icon” even before her AV entry, a former SKE48 member at peak mainstream visibility. Launching the inaugural title with this tier of talent announced the program’s ambitions. Not a new-performer trial — a flagship-tier positioning statement.

Early-era shooting carries breathing room in duration and technical density. That margin becomes the key to reading the series’ evolution. Eight years hence: how did the numbers inflate? This title as the measurement baseline.

First “Triple-Intensity” Variant: Miru Sakamichi, 2018

Title: “193 Climaxes! 4,700 Convulsions! 10,000cc Squirt! Sexual Prodigy 18-Year-Old Eros Awakening Triple-Intensity Convulsion Special.” The standard “Great” modifier expanded to “Triple-Intensity,” a first appearance of this enhanced variant. 10,000cc squirt production and 148 reviews marked it series-third in review count. “Sexual Prodigy 18-Year-Old” framing and the title variant appearing on the same release shows what happens when on-set feedback signals capacity beyond standard parameters. Tracing the variant lineage begins here.

Review-Count Record: Uta Hayano, June 2021

Not a numbers-chasing title. June 2021 release: 108 climaxes, 4,800 convulsions, 1,500cc squirt — modest figures by series standards. Yet 344 reviews crushed second place (Ria Yamate with 164 reviews). More than doubled the next-closest. “Pure White G-Cup Girl” framed the headline. Ratings split at 3.87, making this “the most-discussed title” in the series’ history. A sample video would expose why 344 reviewers converged. The narrative peak deserves lineup placement alongside the three numerical peaks.

Squirt Record: Mai Ushio, January 2021

10,200cc squirt — the series’ apex and the only figure cresting the 10,000cc threshold. Titled “Pale Slender Incontinence Type,” the performer carries “Ushio” (tide/squirt) in her stage name, a fitting symmetry. 4.64 rating and 44 reviews place this in series upper tier. Record-setting figures paired with audience satisfaction — rare alignment.

Title Variant Lineage

Departures from the standard “Hajimete no Dai Keiren Special” formula function as flags marking off-standard productions.

“Triple-Intensity” began with Miru Sakamichi (2018), continued with Rikka Inui (10,000cc, 2019), and through Marin Mita (2024). “Career-Best” first appeared with Miu Nakamura in 2020 as a five-consecutive-scenes special. Unpai (2022) shifted it to “Career-Best Triple-Incontinence Non-Stop,” continuing through Yuka Murakami (2023). ”& Great Deluge” debuted with Mai Ushio’s 10,200cc title (January 2021), carrying into Kozue Fujita (June 2021).

Variants appear even in the first year — Sakura Mizuuchi’s November 2017 title carried “Demon Thrusts 15,000 Pistons,” a fourth axis beyond climax count, convulsions, and squirt. This notation never standardized afterward. Both the variants that survived and those that faded remain cataloged.

Collecting only variant titles and comparing them sideways becomes unique entertainment within this series. Variants represent less than ten percent of 83 titles, their rarity itself marking “something happened on set.” The deviation flags the anomaly.

Eight-Year Progression and the Halted Shelf

From 92 climaxes to 340 climaxes, the series inflated 3.7-fold across eight years. Product code series switched four times, shooting and editing formats updated with each generation. 2017 through 2025: roughly one title monthly. Stable supply cadence across the entire run.

Review distribution carries era signatures. The top-ten review counts lean 2020-2022. Uta Hayano at 344, Ria Yamate at 164, Aka Arisugawa (now performing as Shiyo) at 129, Mahina Amane at 83 with 4.52 rating, Ren Hirose at 80. Recent releases flip the pattern: Kiho Kanematsu at 4.65, Yu Tano at 4.57, Rika Natsuzora at 4.78 — top-tier ratings but 57, 54, and 9 reviews respectively. The shelf shifted from mass review-writing to selective single-purchase. Purchase behavior itself transformed across eight years.

Supply halted in February 2025. Since Rika Natsuzora’s title, no new releases for seventeen months. No official conclusion was announced, but reverse motion has already begun — one title vanished from distribution mid-2026 (84→83). Growth shelf became declining shelf. Comprehensive reading requires catching it while the catalog remains intact.

Complete Best: 5,608 Total Climaxes

A shortcut through 83 titles exists. A February 2024 complete-best compilation spanning 40 actresses from series appearances collected 100 scenes. The aggregate numbers stamped into the title: 5,608 total climaxes, 115,782cc total squirt. Convulsions earned ”∞ total convulsions” — numerical tallying abandoned for this metric. 4.80 average rating ranks high for a compilation. Nearly half the series’ performers accessible in one purchase. Broad-and-shallow approach versus deep single-performer dives becomes the fork determining orientation.

Final Two Titles

Climax Record: Kiho Kanematsu, October 2024

The October 2024 release opening this article’s analysis: 340 climaxes, 5,800 convulsions, 2,900cc squirt. Kiho Kanematsu, a gravure entertainer with crossover-media visibility, set the series record. 340 obliterates second place (Sakura Kageyama at 251) by 89 climaxes. Top-tier record with top-tier rating: 4.65, 57 reviews among recent-era highs.

Carrying 340 climaxes in mind during playback shifts temporal perception. Standard titles enable climax-counting; this one crosses into uncountable territory in the opening sequence. Attention pivots from enumeration to screen density immersion. That shift’s velocity becomes the record’s embodied sensation. A sample video would expose the pacing. One title summating the entire series’ eight-year arc. This is the apex.

Current Final Release: Rika Natsuzora, February 2025

218 climaxes, 4,400 convulsions, 2,850cc squirt. The 83rd title, the current catalog endpoint. In 2017, 218 climaxes would have ranked peak. Eight years later, it registers as standard-range baseline. This title’s 4.78 rating approaches series maximum. Format maturation crystallizes in the final release.

Unknown whether 84 will arrive or whether 83 closes the count. The only certainty is the catalog’s right edge holds this title now. The shelf’s contemporary terminus. The records journey’s closure point.

Ideal For

• Viewers seeking numerical gratification: 340 climaxes, 6,690 convulsions, 10,200cc squirt — measurable metrics exist nowhere else in series catalogs. Counter-pressing becomes the viewing framework
• Viewers wanting S1’s new-talent development in real time: Exclusive-roster casting clusters densely; later-era top-tier performers’ pre-ascendant “Eros Awakening” moments stand documented
• Viewers favoring sustained-climax extended-duration assault: Series construction prioritizes sustained multi-stimulation; per-title climax density runs elevated throughout
• Viewers seeking series-catalog synchronic viewing: All 83 share identical title formula; collective viewing exposes eight years of S1 catalogue as tangible numerical artifact

Summary: From 92 to 340 Climaxes — The Shelf Solidifies at 83 Titles

From the 92 climaxes, 3,600 convulsions, 2,300cc squirt of March 2017 to the 340 climaxes of October 2024: eight-year expansion documented through numerical sequence.

The 83 spines align nearly identically on the shelf. Variation appears only in actress photographs and three opening numbers. Interpreting that variance determines series comprehension. Among 83 titles, numerical distribution serves every preference.

Free streaming sites offer digest compilations; shooting assembly rationale and per-actress reactive micro-variation surface only through complete FANZA releases. The thirty-minute digest compression cannot convey extended-foreplay intentionality or break-elimination construction. Supporting a favorite performer means acquiring that title through authorized channels. What three numbers open 2026’s approaching 84th entry? The series remains update-pending.
