Toriyama Sekien
Aoandon, or Aoandō ( 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. 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.
