WARNING: The following contains spoilers for Season 2 of Demon Slayer: Kimetsu no Yaiba, now streaming on Funimation, Crunchyroll and Hulu.
Demon Slayer Season 2's "Entertainment District" arc recently ended on a relatively positive note. Not only were Upper-Rank demons killed for the first time in a century, but the Hashira whom Tanjiro and co. were helping didn't die; Tanjiro was able to pull his weight in this fight and save the day. With all that said, there are still plenty of loose ends left to tie up.
Naturally, the Demon Slayer Corps will still have to deal with Kibutsuji Muzan and the rest of the Kizuki, but there's more. Several hints about what to expect later down the line were dropped throughout Season 2. There are also events that seem like they'll be exclusive to this season but left fans scratching their heads. With these hints in mind, here are some of the biggest questions that have Demon Slayer fans chomping at the bit for answers.
How Exactly Did Tengen Uzui End Up With Three Wives?
Whether it's out of jealousy or curiosity, Tengen Uzui's wives spark a lot of questions among Demon Slayer fans. He was somehow able to win the hearts of three very different women and marry them all. Unless he's some sort of harem protagonist, it's hard to understand how this is possible.
On one hand, there are questions of how Tengen met all these women, how they each fell for him or if it's even legal to have a polygamous relationship in Japan (it's not). On the other hand, his situation is highly enviable to other characters, as shown by Gyutaro clawing his own face out of jealousy. Viewers, meanwhile, are left wondering just how Tengen's situation manifested itself.
Who's the New Mystery Demon Bearing the Upper-Rank Six Title?
Apparently, Daki and Gyutaro aren't the first Kizuki to bear the title Upper-Rank Six in Demon Slayer. Back when they were humans dying in the street, they were stripped of their humanity by a passing demon. A closeup on this demon's eyes revealed that his pupils are shaped like the kanji for "Upper Rank" (上弦 Jogen) and "Six" (陸 Roku).
Not only is this a new Kizuki, but there's a question as to where he is now. Since he was the Upper-Sixth when he turned Daki and Gyutaro into demons, it's possible he has since been either deposed or promoted. Considering the big deal Demon Slayer made of his introduction, it's likely the latter. If that's true, then Tanjiro and co. can be expected to go up against this powerful demon sometime in the near future.
Who Was the Mysterious Man Daki Saw?
While fighting Tanjiro, Daki received a mysterious vision. As he was berating her for all of her killing and wanton destruction, it "reminded" her of another demon slayer with similar questions. The only problem was that Daki had never actually met this mystery person, so she shouldn't have any memories of him. She surmised that these memories weren't her own, but instead those of Muzan. This makes sense as the Upper-Rank demons all receive copious amounts of Muzan's blood to acquire their power. Since Daki is one with Muzan in this sense, it's reasonable to assume she shares his memories.
Who this demon slayer is, however, remains a mystery. It's likely he's an impactful person from Muzan's life if he's bothered to remember him like this. Whatever this man did, learning about him should be a highly anticipated event in Season 3 of Demon Slayer.
How Can Tanjiro & The Others Get Stronger in Season 3?
Despite their growth, Tanjiro and the heroes have shown they still have plenty of room for improvement. In Season 2, Tanjiro was able to mix Sun Breathing with Water Breathing to reduce the strain of the former. However, this is a crutch for him; if he's looking to fight stronger Kizuki and eventually Muzan himself, he'll have to learn how to use Sun Breathing in its pure form.
Tanjiro's allies also show how they can improve. Zenitsu's singular attack, while effective, is beginning to reveal its upper limits. If he means to be helpful in future confrontations, he may have to broaden his arsenal. On the opposite end, Inosuke's flexibility, while versatile, doesn't change the fact that he can't fight high-level demons without help. Nezuko's demon powers, however, seem to be evolving at a steady pace.
Who Is Iguro Obanai, The Serpent Hashira?
The Serpent Hashira's appearance at the end of Demon Slayer Season 2 is bound to raise questions. Iguro Obanai arrives on the scene and gives Tengen the most backhanded compliment imaginable; he repeatedly emphasizes how bad it is that his fellow Hashira ended up in his current state fighting the "weakest" of the Upper-Rank demons. On a more serious note, he chastises Tengen for choosing retirement over fighting until his dying breath. This value he places on the Demon Slayer Corps' duty is also hinted at during Tanjiro's trial.
Iguro is also surprised to find that Tanjiro survived the battle. According to Tengen, the Serpent Hashira has a particular interest in Tanjiro. In any case, his surprise appearance leaves viewers wondering who he is, what he wants with Tanjiro, why he holds the Demon Slayer Corps in such high regard -- and what the deal is with the snake around his neck.
