The Big Hint Everyone Missed In Demon Slayer's Entertainment District Arc

The hit anime series "Demon Slayer" continues to make waves with the release of its "Entertainment District Arc." Following the events of the record-breaking "Mugen Train," which is now Japan's highest-grossing film ever (via Funimation), and Season 2's recap, the arc follows Tanjiro Kamado and his gang of fellow demon slayers, Zenitsu Agatsuma and Inosuke Hashibira, as they embark on a deadly new mission.

In league with the Sound Hashira Tengen Uzui, the "Entertainment District Arc" sees Tanjiro, Nezuko, and co. head to Yoshiwara, Tokyo in search of Tengen's three missing wives. Tengen's wives were investigating rumors of demons plaguing the district and, of course, Tengen and Tanjiro ultimately find themselves going head to head with those very demons.

After going undercover as a concubine, Tanjiro discovers that the demon known as Daki is the menace of the Entertainment District. As a member of the Twelve Kizuki, Daki is an extremely powerful demon, and it doesn't hurt that she has a blindingly fast belt that can slice through anything. However, Tanjiro is able to hold his own against the demon and the two engage in an action-packed battle right up until the moment when Nezuko is forced to fully transform into her demon form and help out.

Fortunately, when Nezuko is about to lose control as a human, Tanjiro is able to stop her and Tengen arrives to behead Danki. What follows is an epic plot twist that, unless you were paying close attention to the arc's opening credits, you probably had no idea was coming.

Episode 7 of the show's "Entertainment District Arc" sees the Hashira Tengen Uzui swoop in and behead Daki. However, just as Tengen starts to contemplate why Daki's body hasn't started disintegrating after he cuts off her head, another demon starts to emerge from her back. We see that it's Daki's brother, Gyutaro, who seems to be an even more powerful demon and is easily able to dodge Tengen's advances. The reveal undoubtedly comes as a shock to "Demon Slayer" viewers, as many believed Daki to be the true antagonist of the season. 

The jaw-dropping reveal seemingly comes out of nowhere as well, especially considering previous "Demon Slayer" episodes gave no indication that there would be another demon involved in the arc or that Daki had a brother. That said, the show does subtly hint at Gyutaro's role in a blink-and-you'll-miss-it moment in its opening credits. 

The moment in question (captured in the above image) is a brief shot of Gyutaro's grotesque outline as well as his blood sickles. That's right: The show's opening credits do, indeed, show Gyutaro. The character's appearance is remarkably brief though, so it's no wonder why many "Demon Slayer" fans were still so shocked to see him in Episode 7.

His official introduction, unfortunately, just makes Tengen and Tanjiro's lives that much harder.
