Kashira

The Kashira("Head") are a strange trio of brothers that live in Yubaba’s office. They are merely heads, and move about by bouncing on the floor. These heads are apparently ordered by Yubaba to push Haku into a chute when he lies gravely wounded after being cursed. Usually closely following Yubaba, they may be her bodyguards or servants, if not just some bizarre pets.

Appearances
The trio makes their first appearance in Yubaba's main office when Chihiro (Sen) arrives to request a job. They bounce around her and seem to stare her down, similar to what a dog would do upon encountering a new guest.

They are seen again attempting to dispose of a dying Haku, but are stopped by Chihiro and subsequently turned into a mimic of Boh, Yubaba's large baby son, by Zeniba.

After Haku informs Yubaba that her real son is not in her presence, the mimic transforms back into the Kashira.

Trivia

 * It is not made clear how intelligent the three heads are, however they seem to be aware that Chihiro is writing something when she is signing her and Yubaba's contract. They are apparently made curious by this as they try to jump up to get a peek.
