Aoandon

Aoandon, or Aoandō (青(あお)行(あん)灯(どん) or 青行燈, "blue andon") is a creature illustrated by Toriyama Sekien in his Konjaku Hyakki Shūi. It was meant to represent the spirit that appeared during the game Hyakumonogatari Kaidankai, after the last story was told.^[1] The candles in the room during these meetings were often placed in blue-paper andon lamps in order to create an eerie atmosphere, hence this creature's name.
