History
A girl named Damiko was beckoned by Yapool that he promised her that she would see her mother and she was hired to become the She-Devil. TAC wondered if this act was to stop their V7 missile plan. The fireflies appeared to weaken Houkuto and Minami and were drawn by the She-Devil. Minami bonded with Damiko and tried to watch over the paraplegic girl. One night, Minami was suffering under the fireflies. Minami broke the bond between the She-Devil and Damiko. Damiko was able to walk and told Minami that Yapool can let her see her mother. Yapool told Hotarunga to come to his orignal size and stop TAC's V7 plan. Hotarunga does so and sucked Damiko and Minami in his abdomen. TAC saw Hotarunga and began attacking. After spraying a gas in Hotarunga, he ejected Minami and Damiko. Hokuto and Minami became Ultraman Ace and decided to fight Hotarunga. The acid that the chouju sprayed seemed to take effect but Ace managed to get the upper hand. After a lengthy battle, the TAC fired their missile straight at the giant firefly's forehead. Hotarunga was finished off by the Metalium Beam by Ace.
