Ultraman Ace

The Extradimensional Being Yapool invaded Earth with an entourage of "Terrible-Monsters" more powerful than ordinary monsters. The Terrestrial Defense Force was annihilated by Terrible-Monster.

Ultraman Ace vested his life and power in Seiji Hokuto and Yuko Minami. When the Ultra Rings glitter after performing Ultra Touch, Hokuto and Yuko unite and transform into Ultraman Ace.
