Finally, the long-awaited massive S1 collaboration is here! SONE-560!
Do you remember when we got hints mid-year through social media photos of actresses that S1, the top-tier production company in the industry, was mobilizing a huge number of performers for a grand event? The project has now been revealed, and we can finally see who participated and why S1 chose this moment to showcase its strength:
The reason? “20th Anniversary.”
Yes, from its founding in 2004 to now, S1 has been with us for 20 years, which is a big deal. So, naturally, they aimed to get as many actresses as possible involved in this epic collaborative project. Who were these actresses? Let’s take a look at the lineup:
(As ranked on FANZA): Honjo Ai, Kohinata Miyuu (Kohinata Miyu), Miho Nana, Kanematsu Kiho, Kagura Momoka, Murakami Yuka, Mita Marin, Kaede Fua, Miru, Okuda Saki, Kawagoe Niko (Kawagoe Rinko), Nagisa Airi, Tano Yu, Kawakita Saika, Nanatsumori Riri, Nosaka Hiyori, Asano Kokoro, Shirakami Saki, Gojo Ren, Kodama Nanami, Hayasaka Hime, Ashitaba Mitsuha, Kuraki Hana, Sakakibara Moe.









With so many actresses, the final setup is a 24-on-24 mega orgy. I won’t elaborate too much on this—fans who love it will really love it, while some may find it overwhelming. For me, the highlight of watching such scenes is scrutinizing individual performances. Ever since I noticed people slacking off in previous all-out scenes like SOD STAR’s, I’ve taken to watching in slow motion to catch each detail. From the previews alone, you can already see Miru standing out with her relentless squirting, despite the crowded scenes.
Let’s look at the subgroups. This is essential because having an all-out scene the entire time would be monotonous. The usual strategy is to break the actresses into groups for varied performances. How they are grouped and which actresses are paired together is quite strategic:
1) The Ultimate Beauty Group: Kawakita Saika, Kanematsu Kiho, Honjo Ai.



Wherever Kawakita is, it’s bound to be the main stage. According to one of the actresses involved, even though everyone is an exclusive S1 performer, Kawakita’s presence commands attention, so those paired with her are carefully chosen. Kanematsu, a former prominent gravure model, is a natural match. Honjo Ai’s inclusion was unexpected, suggesting that S1 holds her in high regard, enough to pair her with Kawakita. Unfortunately, she is currently on indefinite hiatus due to a scandal.
2) Pool Battle Group: Nagisa Airi, Nosaka Hiyori, Murakami Yuka.



This trio doesn’t have much in common at first glance. Perhaps the most noteworthy point is Murakami recently releasing a one-year anniversary compilation. Also, it’s surprising that Nosaka, who has only released four works (including one VR), was included. The reason is simple: by the time this was filmed, she had already debuted. However, her information (filmed in June, debuting in September) wasn’t public then, so no one included her in the predicted lineup.
3) J, K, L Cup Orgy Group: Tano Yu, Kagura Momoka, Gojo Ren.



This one is self-explanatory—gathering the actresses with the largest chests. Breast lovers, don’t miss this!
4) Bathroom Ambush Group: Okuda Saki, Kaede Fua, Ashitaba Mitsuha.



Two long-legged beauties teamed up with a veteran big-busted star, lying in wait to ambush actors heading to pay the water bill. Kaede and Ashitaba make sense together, but the purpose of adding Okuda isn’t clear to me. She’s not particularly tall or young, yet her chest stands out when lying down.
5) Cute Girls Bathing Group: Hayasaka Hime, Kawagoe Niko, Miho Nana, Shirakami Saki.



Set in a bathroom, these four actresses have been frequenting Taiwan recently, which speaks to their popularity and prowess.
6) Night Attack Girls Group: Sakakibara Moe, Kodama Nanami, Kohinata Miyuu.



This group is quite significant. First, Kohinata Miyuu (formerly known as Kiyohara Miyuu) is the “last actress” to join this collaboration. Why is this noteworthy? We all know that she changed her stage name after switching agencies, which allows us to confirm that S1 planned this collaboration after her name change. Therefore, actresses who debuted after her name change were essentially too late to participate. As for Sakakibara Moe, anyone who follows S1’s social media knows that she is a key focus for future development. Also debuting in September, her promotion has been leagues ahead of Nosaka Hiyori’s, showing just how much more heavily she is being pushed.
7) S-Class Temptress Intrusion Group: Asano Kokoro, Miru, Nanatsumori Riri, Mita Marin.



This group features S1’s powerhouses—beautiful faces and seasoned acting skills, making for the most sophisticated lineup. The male performers are simply there to be dominated.








Finally, there’s the massive all-cast orgy. I know some people may have noticed that Kuraki Hana wasn’t assigned to a group and may be curious why certain actresses did not participate. We’ll cover those details in the next article. Despite some uncertainties in the lineup or questions about the group compositions, this film is undoubtedly the most powerful collaboration from the industry’s leading production house and is sure to be December’s top hit!
