In Jujutsu Kaisen Manga Chapter 20, Kento Nanami explains his cursed technique to Yuji Itadori, revealing that it allows him to identify and create weak points on his enemies. With precision, Nanami can exploit these vulnerabilities, cutting through opponents even with his bandaged blade. While demonstrating, Nanami notices Yuji is too absorbed in fighting enemy curses to fully listen. He further explains that under certain conditions, revealing a cursed technique to an opponent can actually amplify its power. Nanami then strikes a curse’s exposed weak points with the back of his wrapped blade, effortlessly neutralizing it.
