The sword causes Subaru to retreat, allowing Phantom Black to peacefully investigate the pyramid alone. To make matters worse, Burai soon appears and knocks Rockman unconscious. Within Subaru's psyche, he encounters the sword thrust into the ground. In an allusion to The Sword in the Stone, Subaru is able to pull the sword from the ground, awaken, and take control the Thunder Berserk form to defeat Burai. Meanwhile, Phantom Black finds that, unfortunately, the pyramid holds no treasure.
