Setsuna and Moroha set out to track down Bokusenō, who, according to Tōtōsai, could lead them to a kyūyōkon root. At the corpse dealer Jyūbei, Moroha learns that there is a yōkai that could possibly lead her to Bokusenō. Unfortunately, nobody knows what it looks like and something terrible should overtake everyone who sees it. In addition, this yōkai is said to hunt women with long, pretty hair.
