From anime and manga to TV dramas and films, unique themes are increasingly popping up to grab audience attention. The adult film industry is no exception, moving beyond just adaptations to explore all sorts of professions and concepts.
A recent post on Japan's X (formerly Twitter) has brought an old review from the adult video platform FANZA back into the spotlight. The AV in question features a "shogi" theme, with actresses playing a "yandere sister seducing her brother" and a "genius shogi player." However, one buyer wasn't impressed, penning a lengthy review criticizing the lax game design and shogi moves, leading Japanese netizens to jokingly dub them the "Shogi Police."

First, some quick info on the film: it's titled "My Sister Seduces Me with Her No-Bra Peeks" and stars Rurucha, Nanami Yokomiya, and Yuzu Shirakawa. Oh, and it's a VR flick! XD
(Note: Nanami Yokomiya passed away in 2023.)

The viral content is a FANZA review where the buyer directly critiques Nanami Yokomiya's shogi game in the film, giving it four stars. Here's a translation:
"The film establishes both the brother and sister as shogi masters, yet the brother's skill is utterly crushed by his sister, Nanami. Nanami is supposed to be a 'genius' shogi player, right? But the film completely fails to convey this. Let's look at the opening of the second game. The first player is the brother, the second is Nanami.
▲7-6 Pawn → △7-4 Pawn → ▲5-6 Pawn → △5-4 Pawn → ▲7-8 Gold → △5-2 Right Gold → ▲6-9 King → △6-2 King → ▲7-7 Knight →【△3-2 Knight】→ ▲6-6 Pawn
The game stops here.
But before this, Nanami already played '△3-2 Knight,' meaning she moved her knight before moving the right bishop. By normal shogi rules, this move is actually an illegal loss. It's incredibly jarring to have a character constantly mock her brother's poor shogi skills when she doesn't even know the basic moves of the pieces. This makes it seem like Nanami is just randomly mimicking her opponent, not like someone who genuinely plays shogi. If the game only shows a few opening moves, they should at least prepare a shogi score and film according to it; otherwise, the characters' skill cannot be portrayed."
"Even more absurd is the second game: after the pieces are set up, Nanami inexplicably has an extra captured piece (komadai piece) in her hand. This means that, for some reason, there are 41 pieces on the board. The staff's lack of attention to detail is astonishing. In contrast, the first game at the beginning was handled quite well.
Nanami played a winning move, '△7-9 Silver,' while the brother made an undefended '▲7-8 King.' Nanami then followed with '△6-8 Rook,' launching a flawless attack. (Though her explicit call of 'Check!' did somewhat reveal her amateur status.) This sequence of moves was logical and effectively showed the brother's inferior shogi skill compared to Nanami. If the first game could achieve this quality, why did the second game go completely off the rails?"
"Without a nuanced portrayal of her truly superior shogi skills, Nanami's character falls flat, and the entire shogi segment becomes meaningless. Just because it's an adult film doesn't mean the plot development should be rushed. If you're going to include a shogi scene, you should carefully consider its purpose. That said, after the shogi board was cleared, the actresses' AV performances were still excellent, so viewers can rest assured on that front."

This review quickly grabbed the attention of many Japanese netizens, who jokingly remarked, "Typical Shogi Police, even critiquing an actress's performance!"

Others agreed with the review, arguing that if a shogi theme is used, it should be thoroughly researched rather than haphazardly thrown together. The same principle, they noted, should apply to any other competitive sport or game.

Some commenters lightened the mood, quipping, "They definitely finished watching it before writing that review, right?" and jokingly suggested the reviewer might be none other than shogi prodigy Sota Fujii. XD

Guess it just goes to show that even in AVs, if you're going to use a specific theme, you'll still have experts—or "police" of that particular field—ready to scrutinize it. XD It's not enough to just put effort into the filming itself; trying to half-ass a theme will definitely get you busted!
