When I woke up, I had become Daigu, destined to become light.
In this world of Ultraman Tiga, where monsters appear constantly and danger lurks everywhere, I have no choice but to take on the duty of protecting humanity and fight as Ultraman Tiga. But unlike the original story, I have a secret buried deep inside me, one that only I know: I know that deep within the ruins of Luluye, a dark giant consumed by love turned to hatred, Camearra, lies sealed away. The one who once inhabited this body shared an unbreakable bond with her.
While carrying out my duties as a GUTS member and forging deep friendships with my teammates, I cannot forget her. I find her before the time comes, and, as she pours out three million years of resentment and love that has never died, I tell her a half-truth: “I’ve lost my memories, but I know you’re my beloved.”
I free her, get close to her, and win her trust. Under Camearra’s guidance, I begin to touch and learn to control the powerful, dangerous force inside me, a power that once belonged to Dark Tiga. Light and darkness clash within me, bringing both pain and power. At the same time, I have to carefully conceal from GUTS the aura that is gradually changing.
When the ultimate darkness, Gatanothor, descends and black fog blankets the world, I am no longer fighting alone. The powers of light and darkness finally merge perfectly within me, reaching a realm never seen before. Camearra and I, lovers and comrades who have crossed the boundaries of time, light, and darkness, stand side by side and launch our final battle for the future of this world and for the happiness we share!
