Korō-Bi's Tōrō is broken when Rikako bumps into it, where she and her friend Mickey quickly leave, not long after he is released. Angered, he confronts the girls, whose screams alert Kitarō and the others. After being momentarily bound by Kitarō's Chanchanko, he flees into the forest. He finds the girls' friend, Ma-chan, where he chases after. The girl is shortly rescued by Ittan-Momen, where they land by a river. Korō-Bi manages to catch up to them and blasts a fire ball at the cloth Yōkai. The others arrive, but Ittan-Momen insists to let him fight Korō-Bi, who blasts another fire ball. He fires another one as Ittan-Momen charges after him, sending him into the river. This however regenerates him from the burns, who uses the water he soaked up to douse him. This extinguishing the flames around him and shrinks him, making him come back to his senses. After Ma-chan's confession to Kawauso and subsequent chase, he asks Kitarō and the others on what he should do. Afterwards his Tōrō is restored and he thanks them, returning into the stone lantern.
