I Thought I Was Ultraman

I traveled through time and became a black-red giant. The memory is fragmented, and I only remember "Ultraman is righteous." So it was natural for me to protect the earth, fight monsters, and be a hero. Humans call me "Dark Light Giant" and there is fear in their eyes, but at least they accept me. Until the real Ultraman arrives and reveals the truth in public—— My energy corrupted the earth, my hands slaughtered the stars. I am not a giant of light. I am the dark giant, the successor of the ancient disaster, and the public enemy of the entire universe. Humanity wants to destroy me, and the Kingdom of Light wants to judge me. The only one who believed in me was a ten-year-old girl. "Color doesn't mean good or bad," she said. But when she fell in a pool of blood, the last light in my heart was extinguished. In that case—— Then let the world see how the dark giant protects the earth.
