She is an onryō, or a vengeful spirit, who lurks in urban areas and roams train stations at night.
As with the original iteration of the legend, Kashima died when her legs were severed from her body by a train after she fell on the tracks.
[6] The legless spirit of Kashima Reiko is said to haunt bathroom stalls, asking occupants if they know where her legs are.
[4] If a questioned individual replies with an answer that Kashima does not find acceptable, she will rip or slice them in half.
[7] Individuals may survive the encounter by replying that her legs are on the Meishin Expressway,[7][8] or by responding with the phrase "kamen shinin ma", or "mask death demon" (which may be the phonetic root of Kashima's name).
