NATG X 14: Pony Sekibanki

Day 14: Fairy Tale/Ghost Story

It's Touhou's own rokurokubi, Sekibanki! In Japanese mythology, rokurokubi were women under a dark curse, whose heads would detach and float around on their own while they were sleeping. The ones with extending necks preferred pranks and lamp oil, while the ones with detached heads (nukekubi) went for blood!
