Hanako of the Toilet

No depiction of Hanako exists within the material. Because she is only ever talked about rather than shown, what she actually looks like remains entirely unknown.

Nothing is established about her temperament or behavior. Since she has yet to make a direct appearance and exists purely as a topic of conversation, her personality stays a complete blank, with the source offering no clues to her nature beyond her classification.

Her name first comes up in Phantom Parade a few days past the Kyoto Sister-School Goodwill Event, when the trio of Yuji Itadori, Megumi Fushiguro, and Nobara Kugisaki head to a derelict school on Tokyo's edge to clear out curses. Sensing something off about the building, Yuji jokes that a ghost seems likelier than a curse, prompting Nobara to raise Hanako as an example, while Yuji counters with the music-room legend of a Beethoven portrait whose eyes follow people. Megumi cuts through the banter, confirming that Hanako is no mere rumor but a verified special grade curse who would put them in genuine peril if encountered, to which Yuji jokingly resolves to steer clear of the toilet. Ranked special grade, she is implied to hold immense power, though without a direct showing her actual capabilities cannot be measured. The character draws directly on the well-known Japanese urban legend that shares her name.
