A realistic depiction of a rokurokubi in a strange pose. The setting is an Edo-period backdrop commonly seen in horror films, reminiscent of the Japanese movie 'Ju-on'. The scene is dark and atmospheric, capturing the horror aesthetic. The rokurokubi should have an elongated neck in a haunting way, with a ghostly appearance, standing in an eerie posture.
