- Name: Kumo Sōkei, 蜘蛛巣域, literally "Spider Web Area"
- Type: Hiden, No rank, Supplementary, All ranges
- Users: Kidomaru
If Kidomaru is in enemy territory and needs to rest while still remaining on guard, he can lay spider thread throughout the surrounding area. Most ninja will recognize the thread as common spider web; however, this thread runs all the way back to a finger on Kidomaru's hand. Slight movement against a webbing thread will pull it all the way back to Kidomaru's finger and alert him to the enemy's presence.
