Nanami Kento, a Grade 1 Sorcerer in Jujutsu Kaisen, possesses a formidable curse technique known as the Ratio Technique. This technique allows him to divide his targets into ten equal parts and strike at their critical point (7:3 ratio) to inflict devastating damage. Despite its immense power, the Ratio Technique has limitations against opponents like Mahito, who can manipulate their soul and negate physical damage. Nonetheless, Nanami’s strength, speed, and strategic intelligence make him a formidable opponent, capable of obliterating high-level curses.
