Using the Jūgen of can stick to surfaces. They stick to things using retractable microscopic hairs on the bottom of their fingertips and the soles of their feet. The hairs retract hydraulically in a similar manner to how spider legs work. These hairs are so small that they create electrostatic connections to interact with surfaces on a molecular level. They get very close to the atom surfaces and actually develop forces from atomic to atomic interaction, so they are really sticking in between the atomic structure and getting the atoms close enough to each other that they form temporary molecular bonds between the body and another object. This enables the clansman to cling to solid surfaces with vast force and scale walls simply by placing their hands on them.
