Mononote: Edo Kiketsu Ninja Emaki (Pilot)

Long, long ago in a certain land, the world was disturbed by a "demon". The demon was "deformed" and didn't even stand 6 feet tall. His jet-black eyes sank into the depths of hell. The people seeing the atrocious and blood-starved appearance of this "deformed demon", trembled in fear. In the tenth year of the Kan'ei era (1633), during the early years of the Edo period, one such demon still exists...as to why he "deformed", the reason will astonish you! Source: MU
