When it comes to Demon Slayer, there's one character who might be even more important than the titular hero this show is named after. Emphasis on "Demon," rather than "Slayer". Yet in Demon Slayer: Infinity Castle, said demon is basically nowhere in sight.
Yep, Tanjiro Kamado might be our beloved hero, but it's Nezuko, his sister, who inspires everything that the slayer does throughout this saga. She plays a vital role in this story, which is exactly why her absence at the start of Demon Slayer's final trilogy is so surprising and tough to bear (unless you've already read the manga, of course. In that case, Nezuko's removal is more disappointing than anything else).
