The Sick Demon (Demon Slayer KNY)

During a rainy night while staying at an inn before a mission, Nezuko falls mysteriously ill and it causes her to behave in a deliriously savage manner. Though her unchanging small size proves little harm. Tanjiro needs to find a cure for her illness fast before she hurts someone, and finally craves human blood or worse: the Demon Slayer Corps decides to slay her.
