Spider begins destroying Edens Zero from within, with only Hermit capable of restoring the ship's security systems. However, Hermit wishes for the crew to evacuate without her, reflecting on the events that alienated her towards humans. In a flashback fifteen years in the past, Hermit seeks to befriend the human Dr. Müller and his research team, whom she assists in developing a machine to provide energy to the dying robot planet Hook. To her horror, the machine's energy obliterates Hook along with her robotic colleagues stationed there while Müller and the others celebrate, revealing that they engineered the disaster as an act of contempt towards robots. Müller conducts torturous experiments on Hermit for the next two years until he and his team are arrested, leaving the emotionally broken Hermit to distance herself from all human contact. Back in the present, Hermit realizes that she still desires friendship with humans when Shiki and his team refuse to abandon her despite her protests. Encouraged by Shiki, Hermit chooses to be their friend and saves the ship, humiliating Spider in the process.
