Fresh out of university, Di Erqi was watching the Perseid meteor shower when he noticed a meteor veer off course and fly straight toward him. It was so fast that he was knocked out before he could even experience a life-flashing-before-his-eyes montage, then fell into a strange dream.
But in the dream, he wasn’t called Di Erqi. He was known as Tsukasa Kadoya!
The dream began with him, suffering from amnesia, sitting on a bench. Not long after someone named Natsumi Hikari found him, he encountered a horde of monsters. Under “Wataru Kurenai’s” guidance, he recovered the Aurora Curtain and the ability to transform into Kamen Rider Decade. After defeating the monsters that appeared, he began traveling through different worlds and saving them.
He kept doing this until the second “kind soul” appeared.
But when the dream ended, Di Erqi’s consciousness stopped moving too!
