Yakumo Kokonoe

Known by the epithet 'Modern Kashin,' Yakumo Kokonoe serves as the head monk of Kokonoe Temple and the living heir to an ancient tradition of ninja sorcery. As the martial arts instructor of both Tatsuya Shiba and Kudo, he takes pride in his identity as a shinobi rather than a conventional magician. Though he outwardly claims detachment from worldly affairs, his unrivaled intelligence network and formidable capabilities allow him to quietly shape events behind the scenes—making him one of the most influential and inscrutable figures in the series.
