Armour of Sticky Gold

Kidōmaru secretes Spider Sticky Gold from his pores like sweat until it fully covers his body. It hardens when it makes contact with the air, becoming a defensive armour as strong as steel. Kidōmaru can produce the armour very quickly, forming it even against attacks that take him by surprise. As a special property of the Sticky Gold, the armour is fortified against chakra, insulating Kidōmaru from attacks such as the Gentle Fist.
