While Tanjirou is unconscious, the transformed and leveled-up Nezuko goes to absolute town on Daki, to the point where, again, I kinda felt sorry for the poor demoness. When Daki tries to counter by slicing her opponent to bits, Nezzy’s blood not only coagulates, keeping all her parts together, but burns Daki everywhere it splattered, reminding her of her human death in flames long ago.
The problem, is, Nezzy has no limiter but Tanjirou, and by the time he comes to she’s already inadvertently wounded some human bystanders (not to mention scared the absolute shit out of them). When she smells the humans’ blood, she can’t help but charge towards them. Thankfully, Tanjirou is there to stop her from killing anyone. But he calm his sister down and protect the bystanders from Daki, who is partially healed and pissed.
Things look bad for Tanjirou, but Uzui shows up just when he should, cutting all of Daki’s attacking belts in the blink of an eye. And nobody, not even Daki, realizes that he also beheaded her with that same arriving attack. Uzui doesn’t consider her an Upper Rank, as how could someone of such rank be holding their head in their hands like she is now?
Just as I love how Daki is someone with whome you can occasionally sympathize, I also love how nonchalant and casual Uzui goes about his business. When he sees a hulked-up Nezuko trying to break free from her undersized brother, he basically tells Tanjirou to get it together put Nezuko to sleep already. The problem is, Nezzy doesn’t seem to be listening to him.
That’s when Tanjirou takes Uzui’s offhand advice to “sing her a lullaby”, which he does while she struggles. Suddenly she’s transported back to better days when she was walking with her mom, who was singing a lullaby to her baby brother. Big Nezzy bursts into tears, then shrinks and falls right asleep, ending one of the many threats facing the Demon Slayers.
The next problem is that despite being beheaded, Daki’s body isn’t disintegrating. Daki doesn’t think much of this, as perhaps it will just take a while, until Daki starts having a full on tantrum about how mean everyone’s been to her. Then she calls out to her “brother”, and Uzui instinctively goes in for the kill…only for his strike to miss. A second demon sprouts out of Daki’s back and moves her to safety.
The second demon is her brother, Gyuutarou, as grotesque a demon as she is beautiful. He heals her and calms her down in much the same way we’ve seen Tanjirou calm his demon sister. What with Nezzy being almost ever-present in her box, you could say both pairs of siblings are attached by, well, not the hip, but certainly the back.
Uzui didn’t consider Daki an Upper Rank because she was so easy to behead, but beheading didn’t kill her, and now we learn that she’s not only not a single demon, but the brother within her is the demon Uzui has been searching for all along. It made me wonder if you somehow managed to separate Gyuutarou whether Daki could be redeemed, as he’s the brains behind their symbiotic existence, controlling her from within.
For now, she’s very much one-half of the latest boss, and powerful enough that even Uzui will have to break a sweat. With Inousuke and Zenitsu finally catching up and Tanjirou ready to rejoin the fray once he stashes Nezuko away (which…rats), this arc is ratcheting up at precisely the right time.
