Kento Nanami is a former office worker turned jujutsu sorcerer. He has a pragmatic outlook on life, seeing exorcism as a job rather than a passion. His "Ratio Technique" allows him to strike at weak points with precise force. Though he seems strict and detached, Nanami has a strong moral compass and deeply cares for the well-being of others, especially his students like Yuji Itadori. His mature, level-headed approach contrasts with many of the more eccentric.
