Giant Shinidamachū

The Giant Shinidamachū was a demon who intended to absorb all of Kikyō's soul.

History
The Giant Shinidamachū was originally resting in a lake until Naraku's insects disturbed it. The Shinidamachū attacked Kikyō and tried to devour all of her souls. However, Inuyasha arrived in time and cleaved it in half with a single slash of Tessaiga.

Trivia

 * It is unknown whether this Shinidamachū is unique among its kind or if all members of its species grow to this size.
 * Unlike the smaller ones Kikyō was unable to control it.
