The 8th Brigade is growing! As missions become increasingly dangerous, the 8th Brigade needs reinforcement. The strange scientist Licht, who has a link with the Joker, joins the team. And the brigade, in search of someone who could improve and consolidate its equipment, intends to integrate the young Vulcan, a engineer... who hates firefighters! Vulcan stubbornly refuses to join the 8th Brigade, but Shinra desperately continues to try to convince him. It is then that Dr. Giovanni, the captain of the 3rd Brigade, enters the stage!
