In Jujutsu Kaisen Manga Chapter 138, tensions rise within the Zenin Clan as Naoya Zenin confronts his relatives Ogi and Jinichi, mocking them while awaiting confirmation of Naobito Zenin’s death. Though his insults spark hostility, Naoya defuses the moment with a dismissive joke.
Later, when Naobito’s will is officially read, it initially names Naoya as the next head of the Zenin Clan—on the condition that either Ogi or Jinichi approve. However, a crucial clause disrupts Naoya’s ambitions: due to a past agreement with Toji Fushiguro, if Satoru Gojo is ever sealed or incapacitated, Megumi Fushiguro is to inherit leadership of the clan.
Enraged by this revelation, Naoya vows to eliminate both Yuji Itadori and Megumi Fushiguro amidst the chaos in Tokyo to seize control of the Zenin Clan for himself.
