Tanjiro finally chases down the main body of the upper-rank demon Hantengu. However, dawn is approaching, and the rising sun is a threat to Nezuko. Tanjiro's concern for his sister is a distraction from the focus he needs to fight Hantengu, and if he hesitates it could be the last mistake he ever makes! Elsewhere, Tamayo ponders the nature of Nezuko's curse and how she could be so different from other demons.
