Jin'i (迅移, lit., "Swift Movement") is an offensive Toji technique. Using the okatana as an intermediary, the user moves at high speeds that deviate from normal time. The Hidden Realm (院世, Kakuri-yo) is made up of multiple layers, with each one having flow of time faster than the previous one. Thus, the deeper one delves, the more effective their Jin'i becomes. Those with a lot of training can reach the deeper, faster layers.
