A Chinese student transmigrates to Tokyo and unexpectedly acquires an Ultraman Tiga mask. When he puts it on, he becomes the Giant of Light, able to switch between three forms. Without the mask, he’s just an ordinary man who hates trouble.
Dangerous masks that grant their wearers the power of monsters circulate in Tokyo’s underground, and those who wear them are consumed by darkness. The Dark Kingdom’s goal is to resurrect the evil god Gatanothor.
More dangerous still, the mysterious woman he falls in love with is Camearra, the ancient Dark Giant from the super-ancient civilization, and Ultraman Tiga’s enemy and lover from three million years ago.
The choice between light and darkness, the bond between love and hate. Put on the mask and protect the city.
