Settlement Sword (始末剣（しまつけん）, Shimatsuken?) is the unorthodox sword style of the Manslayer Okada Izou, the ability to reproduce any sword technique with a glance. He is limited to the techniques he knew during life when first summoned, but he can become stronger by taking in new sword techniques witnessed after his time of summoning. The limit to the ability is that it cannot copy sword techniques that rely on the special characteristics of Noble Phantasms, and other Anti-Unit Mystic Sword techniques are unable to be reproduced.
