Kimetsu no Yaiba: Tsuzumi Yashiki Hen (2021)

Demon Slayer: Tsuzumi Mansion Arc (2021) follows Tanjiro Kamado as he travels south-southeast and meets the terrified but surprisingly skilled Zenitsu Agatsuma — a fellow Final Selection survivor whose pet sparrow begs Tanjiro to keep him in line. When the group investigates a creepy, music-filled mansion, they confront a sinister demon that uses tsuzumi (drum) magic to warp rooms, manipulate time and space, and terrorize anyone inside. The arc blends tense investigation, close-quarters horror, and fast-paced swordplay as Tanjiro, with Nezuko’s presence and Zenitsu’s unpredictable courage, struggles to save victims and defeat an enemy who turns the house itself into a weapon. Watching this arc, you’ll get a compact, character-driven slice of Demon Slayer: tight, visually striking fight sequences, memorable character moments (Zenitsu’s comic cowardice and surprising bravery are highlights), and a creeping, atmospheric villain whose power is as unnerving as it is inventive. Expect a mix of action, suspense, and emotional beats, accompanied by strong animation, dynamic sound design (the drum motif is central), and the show’s trademark blend of grim stakes and heartfelt resolve — a satisfying, self-contained episode arc that expands the world and stakes of the series.
