- Name: Kumo Nenkin, 蜘蛛粘金, literally "Spider Sticky Gold"
- Type: Hiden, No rank, Supplementary
- Users: Kidomaru
Unlike Kidomaru's binding webs, this technique produces a liquid that hardens into a golden metal. As well as being very strong, the metal is impervious to chakra. Kidomaru can form the metal into various shapes to use against his opponents, as well as quickly forming a protective shell over his body by excreting it from his pores.
