The monsters have arrived.
The city is crumbling, the crowds are screaming, and a high school student named Situ Shun draws a sword
He becomes light, becomes a giant, and turns into the “Serzo Ultraman” reported on the news.
But life as a hero isn't easy. Agents keep an eye on him, a classmate impersonates him, and villains scheme to plunge him into darkness. When his body is stained a murky red and he stands amid the ruins holding a Dark Ring, even he can't tell: am I protecting the world, or destroying it?
“You don't even know who you are, Shun. Your memories are fake. Your life is fake. You're not human. You are Serzo Ultraman himself.”
He loses his light, his companions, and his way. As he kneels before his shattered Color Timer, the girl he had always protected brings back the final glimmer of light, in exchange for ten years of silence.
He is both light and human. He lost his memories, but he won the chance to protect.
