In the 11th episode of "Bullbuster," the stakes are higher than ever: Namidome Industries prepares for a decisive battle against Shiota Chemical over the fate of Ryugan Island.

The episode kicks off with an explosive confrontation between Namidome and Shiota Chemical. Shiota unveils its ambitious plan to monopolize the island's restoration and push Namidome to the brink. Amid the brewing storm, Muto feels his era has come to an end and steps down, passing the torch to the next generation.

The plot thickens as Arumi and Okino make a shocking discovery: the giant beasts terrorizing the island are a byproduct of Shiota Chemical's interference—specifically, the interaction of HR-E bacteria with the local leather coral. This revelation prompts President Tajima to make a bold decision: he intends to expose Shiota Chemical's ruthless schemes and their plan to turn the island into a breeding ground for these monstrous creatures.

In a daring move, Namidome Industries launches a livestream to rally public support and bring Shiota's machinations to light. Meanwhile, Namari confronts his superiors at Shiota in a moral dilemma and defiantly quits to side with Namidome.

Takarada, a new ally, offers Namidome a financial lifeline and proposes a strategic maneuver to secure fishing rights for the island's lake. His goal: the leather coral, a potential cure for baldness.

The islanders, who initially trusted Shiota, now turn to Namidome after Shiota's true intentions—to prolong the crisis with the giant beasts—are exposed. As the episode reaches its climax, Namidome prepares for a final showdown to reclaim Ryugan Island from Shiota's grasp.
