Enen no Shouboutai

Synopsis

At the Rookie Fire Soldier games, Shinra recognizes Leonard Burns, who denies recalling the fire which destroyed Shinra's home and family twelve years ago. The games involve entering a booby-trapped building and reaching a crewman posing as an Infernal. Shinra uses his ability to fly to the top, where he encounters a mysterious man who promises to reveal information about the fire twelve years ago. He releases ash from a vial which causes a series of mini- explosions to defeat Shinra, then reveals that Shinra's younger brother Sho is still alive, and asks Shinra to join him. When Arthur and Tamaki arrive, the man calls himself Joker, and he makes a last offer for Shinra to join him and learn the truth about the Fire Force. Later, Shinra asks his Captain about the Fire Force, and Akitaru responds that the force could not operate without Hajima. He explains that the different Fire Force companies operate independently and do not share information about human combustion, and Company 8 was formed to investigate companies 1 through 7.
