Kusi no Oni

Kusi no Oni was an oni.

Appearance
The Kusi had a large torso and pair of limbs extending up from a cuadrupedal body, with a pair of tentacles extending from its arms. Its four legs were jointed and chitinous like a spider's, letting it to move silently. It had a perfectly human face looking out from the center of its chest. It stroke by leaping atop its victims and strangling them from behind.

Trapped
Kusi no Oni attempted to sneak through the Crab defenses by following a small scouting party returning from the Shadowlands, killing them inside the catacombs behind the Kaiu Wall. It had forgotten how it had entered and the Kusi could no longer escape the catacombs, being lost there for hundreds of years. In the 12th century the Kusi attacked and killed several samurai, vanishing back into the shadows to follow the survivors, in hopes that this would drive them to exit the maze as quickly as possible.
