On patrol, Minami witnesses the sky crack open and a monster emerges. Destroying a bridge with a little boy on it, a passenger plane flies overhead and it, too, is destroyed. TAC investigates the wreckage and finds no sign of the little boy, nor the monster Minami described. Hokuto finds the yellow hat belonging to the boy which happens to have his name, Shiro Nakamori, printed on it. Hokuto locates his parents and upon meeting the boy, realizes something is wrong with him after he swipes his gun and attempts to kill him with it! It's discovered the boy has been possessed by the Yapool, using him as a host for the monster Vakishim. Luring the main TAC members away with a decoy, Vakishim is sent to destroy the TAC headquarters at the base of Mount Fuji.
