Bahan (バハン*)? is a demon in the series.
Possibly based on Tatzelwurm from Alpine folklore, a creature with a head of a cat and a body of a snake. The name Bahan is could be a corruption of a German word "bahn" - train or railway. In Germany, elongated structures and vehicles, such as trains and railways, are sometimes referred to as Tatzelwurm.
Another posibile inspiration for Bahan is horse tripping snake (馬絆蛇) - a Chinese foul-smelling monster resembling a giant snake with a mouse-like or cat-like head, and has a star shaped spot on its forehead. It lives in the river and attacks any passing by humans and horses.
