When I woke up, I became Yuan Dagu - the person destined to become light.
Facing this Tiga world with frequent monsters and dangers, I have no choice but to shoulder the responsibility of protecting mankind and fight as Ultraman Tiga. However, what is different from the original plot is that there is a secret deep in my heart that only I know: I know that deep in the ruins of Luluye, there is a dark giant, Camilla, who is born of love and hatred, sealed, and the original owner of that body once had an unbreakable bond with her.
While fulfilling my responsibilities as a GUTS member and building a deep friendship with my teammates, I can't forget her presence. I found her in advance. Faced with the 30 million years of resentment and unquenched love she poured out, I told a half-truth and half-false lie: "I have lost the memory of the past, but I know that you are my lover."
Rescue her, get close to her, and win her trust. Under Camilla's guidance, I began to touch and learn to control the powerful and dangerous power in my body that originally belonged to Dark Tiga. Light and darkness intertwined and collided in my body, which brought pain and strength, but also forced me to carefully hide the gradually changing atmosphere in GUTS.
When the final darkness - Gatanje'e - descends and the black mist envelopes the world, I am no longer fighting alone. The power of light and darkness finally merged perfectly in my body, reaching an unprecedented level. Camilla and I, our lovers and comrades-in-arms who transcend time, space and light and darkness, join hands to launch the final battle for the future of this world and our common happiness!
