Episode 10 of "Bullbuster" begins with a meeting between President Tajima of Namidome Industries and Washizu of Shiota Chemical. Tajima returns the leaked data and attempts to defuse the situation without pressing charges. Washizu downplays the significance of the data, dismissing it as a minor incident.

Tajima finds himself in a moral dilemma as he grapples with the implications of the merger with Shiota Chemical and the potential consequences for his employees, especially Muto, who is being sidelined due to his age.

Muto, feeling redundant and unwanted, decides to step down from his role, believing it’s time to make way for the younger generation.

Arumi and Okino discover that the giant beasts are the result of Shiota Chemical’s activities, specifically the HR-E bacteria from their factory, which interacts with Ryugan’s leather coral. This revelation suggests that Shiota Chemical is directly responsible for the crisis on Ryugan Island.

Tajima resolves to take action against Shiota Chemical. He plans to release footage of the giant beast and the data linking Shiota to the crisis, despite the legal risks involved.

The Namidome Industries team launches a livestream from Ryugan Island to raise awareness about the giant beast and garner public support. This bold move aims to expose the truth and secure independent funding.

Despite Shiota Chemical’s threats, Tajima refuses to back down, declaring that he will fight for what’s right and protect Namidome Industries.
