President Torauma leads Torauma Industries, the influential corporation bankrolling the Tsukuba Institute’s research expedition in Vietnam. Determined to consolidate corporate dominance and preserve his family’s elite status, he fiercely opposes his daughter Yumi’s romance with Subaru Marita—a university professor’s financially struggling son—and compels her to wed Goyō Yasui, his handpicked successor and trusted lieutenant. A pragmatic strategist with an iron grip on authority, he subordinates personal bonds to corporate ambition. While auditing a U.S. subsidiary, he learns of Yumi’s rebellion through Yasui’s updates and swiftly boards a flight back to Tokyo. En route, his plane is obliterated by Zamba, an indestructible extraterrestrial operative, killing him instantly.

His calculated maneuvers to enforce corporate hierarchy and familial obedience fuel central conflicts, while his abrupt demise propels Yasui into command of Torauma Industries. Empowered by newfound authority, Yasui intensifies efforts to secure Yumi and eradicate Subaru and Lamina. Torauma’s rigid pursuit of control, defining both his life and legacy, ignites the chain of confrontations that follow his death, leaving corporate and personal rivalries to collide unchecked.
