Ultraman + Kamen Rider Ryuga + Transmigration + Power-Ups + Fast-Paced + Devour-and-Evolve + Card System + Mirror World
Transmigrating into the world of Ultraman, Lin En gains the power of Ryuga.
His path is entirely different from that of the warriors of light: defeat enemies, seize their power, and make it his own!
Dan Moroboshi: "Is this dark power friend or foe?"
Leo: "Please, train with me!"
Belial: "Kid, your darkness is fascinating. Become my underling!"
Tartarus: "Why is your time-manipulation ability absent from my prophecies?"
The Dark Dragon roars across the universe, devouring Space Dinosaur Kings, the bodies of evil gods, and even the cores of Ultimate Life-Forms!
Alien Empera, Gatanothor, Hyper Zetton, Greeza... all will become nourishment for the Dark Dragon's evolution!
When the Land of Light faces a crisis and Nexus, Zero, and Z are defeated one after another, a pitch-black knight tears through space and descends onto the battlefield.
"Tartarus, I'll take your core!"
It feels pretty good. But the protagonist doesn't seem to have any clear purpose to express, he just follows the plot.
