==Summary==
The Demon Slayer Corps plunges into Infinity Castle to defeat Muzan Kibutsuji. Shinobu Kocho engages in a fierce fight against Doma, the Upper-Rank 2 demon. Poison doesn't work on him, so she finds herself in an intense struggle. Will she be able to defeat the demon who killed her older sister?! Then another demon appears before Zenitsu Agatsuma, revealed to be Kaigaku - the new Upper-Rank 6 and a former Demon Slayer himself who trained alongside Zenitsu - and blocks his way.
Tanjiro Kamado and Giyuu Tomioka confront Akaza, the Upper-Rank 3 demon. Against Akaza's overwhelming strength, the two find themselves unable to do anything but defend themselves. With the situation looking grim, Tanjiro awakens to the "Transparent World" his father once told him about. Will this new knowledge allow Tanjiro to turn the tables and go on the offensive against Akaza?
