Susukodama

The Susukodama (Soot Kodama) are a furred ball-like soot settling in roof of the Rokumon Junk's interior, appearing whenver Doukoku's infuriated enough for them to descend, annoyingly repeating people's words while giggling. Kodoma are spirits believed to live in certain tree, cutting down a tree housing these spirits is thought to bring misfortune. One accompanies Dayu in her wandering after it is tossed out of the Rokumon Junk and into the mortal realm, singing in imitation of her shamisen. After Dayu sacrifices herself, Doukoku crushes the Susukodama by stepping on it. They are similar to the Dryad of Greek myth.
