Obitaki, chancellor of the Norse clan, drives their conflict with the rival Shine clan in the feudal era. He fiercely advocates continuing hostilities and opposes all peace efforts between the warring factions. His primary motivation is seizing control of Shine Island's coveted natural gas resources through military force. As a key antagonist, Obitaki's order to execute Takaya's father directly fuels Takaya's quest for vengeance, influencing significant plot developments and cementing Obitaki's role as a driving force behind the feud. His aggressive stance and rejection of diplomacy place him in direct opposition to Norse leader Eshika, who expresses doubts about prolonged war and favors a peaceful resolution. Defined by his militaristic approach and relentless commitment to warfare, Obitaki's actions intensify the central conflict faced by Lupin and his companions as they attempt to mediate the clan dispute amidst time-travel complications. Within the Norse clan hierarchy, his leadership position makes him a secondary antagonist whose warmongering policies create substantial obstacles for both the protagonists and peace-seeking members of his own clan. Obitaki possesses facial hair, consistent with his depiction as an adult warrior in the feudal Japanese setting.
