Kun Ben was an ordinary college student on earth. Due to an accident, he was transported to a strange world of immortality that incorporated the horror elements of Strange Tales from a Chinese Studio. In this world, ghosts and demons are rampant, and the road to immortality is extremely difficult. He is bound to a mysterious system called "Light of Tiga" and can transform into Ultraman Tiga, the giant of light, but each transformation requires the consumption of a special "power of faith" - and this power of faith is actually closely related to the "Kun Kun Geng" culture he was familiar with in his previous life.
