After the battle between light and shadow, Xin Nan falls into the Ultraman universe while pursuing an alien beast. The Dark Shadow Emperor and the Emperor Armor follow close behind.
A new battle between light and shadow begins, and a new hero's story unfolds.
Xin Nan: Xincheng, you crash alongside Daigu every day. Your body can't take much more, can it? I've got a suit of armor here. Want to try it?
Xincheng: ...
Xin Nan: Sero, don't you think people look cooler in armor?
Sero: I grew up in juvenile detention. I'm not exactly cultured, so don't push me.
Xin Nan: Jugglus Juggler, you don't want Kai fighting alone, do you?
Jugglus Juggler: I'm never helping him again.
