Is it you who requests my arrival? A youth from another world. From a pure white gate, a handsome young man with blond hair and blue eyes slowly steps out. He lowers his head, calmly looking at the black-haired boy kneeling at his feet. In the distance, a giant several tens of meters tall falls, and opposite him, a dark god roars. Please, you must save Ultraman Tiga! The light, the light is about to disappear! The boy, his face full of sadness and fear, squints his eyes, seemingly stimulated by the light from the pure white gate. He begs in a low voice, as if he has exhausted all his strength. Tiga? And the dark god Gatanothor? Interesting. However, rather than Tiga, perhaps I can become your light. Then, Earth-shattering Star!
