In the darkness, on the outskirts of Osaka, in a place where the monster appeared several times without causing any damage.

Disheveled and unkempt like a beggar, pale and thin, Da Gu quietly climbed over the wall of a residential compound, ascended the drainage pipe to the seventh floor, and entered his home.

After opening the window and entering the main hall from the kitchen, Daigo froze, staring in disbelief at the scene in the dark living room. He collapsed to the floor as if all his strength had been drained, his eyes glazed over as he stared blankly at the two dark figures hanging under the living room chandelier.

Those were his parents. What kind of heartless person could kill his elderly parents and hang their bodies under a chandelier, and it looks like many days have passed.

"Waaaaah..." The next moment, Daigo's tears could no longer be held back, and his sobs burst forth like a floodgate being opened. No longer caring about hiding it, Daigo rushed to the chandelier like a madman and put his parents down. From the bruises that covered the old man's body, he could tell that the old man must have suffered inhuman torture before his death. Those people couldn't find him, so they vented their anger towards him, their anger towards Tiga, their resentment towards him, and their resentment towards Tiga on his parents.

At this moment, his thoughts and ideals were overturned. Why did he transform into light and become Ultraman Tiga? Why did he join the GUTS team? At this moment, the hatred and anger in his heart changed the direction of everything and grew rapidly.

"Crack!" Just then, the Spark Lens, which Daigo had long ago discarded, reappeared in front of him, falling to the ground with a crisp sound. However, the Spark Lens, which had once been brightly colored, had changed. The three colors had turned black, and the brightness had become dim, much like Daigo's current state of mind.

"Humans are no longer worth protecting."

Looking at the unusual Spark Lens in front of him, Daigo slowly picked it up. Then, looking at his parents' faces after their tragic deaths, Daigo finally stopped hesitating, raised his hand, and activated the Spark Lens.

"Daigo has turned to the dark side, and Dark Tiga has finally appeared. It's time to begin the final plan. Ultraman Graveyard."

In the laboratory, Wang Han, who was under house arrest, smiled and muttered to himself. Although the death of Daigo's parents was somewhat unexpected, it was also understandable. Human nature is, at the very least, unpredictable, but he had already achieved the result he wanted.

"Teacher, what did you say?" Mayumi, who was also under house arrest, asked Wang Han curiously. She thought Wang Han was calling her because of his muttering, but she didn't hear him clearly.

"Ants always think highly of themselves before the giants get angry, constantly provoking them with ever-increasing aggression. Only when the giants are truly enraged will they realize how ridiculous and foolish they are." Upon hearing this, Wang Han shook his head and said something that left Mayumi completely baffled.

——————————————————

On the outskirts of Osaka, in the neighborhood where Daigo lived. The moment Daigo pressed the Spark Lens, a dark aura enveloped the neighborhood and gradually spread throughout Osaka Castle.

Next to the floor where Daigo's parents lived, Dark Tiga, his body covered in gray and devoid of its former purplish-red hue, exuding a terrifying and oppressive aura, slowly lifted his parents' corpses into the air and silently took them into his hands.

"Boom...!" The next moment, Dark Tiga raised his foot and swept his leg to the side, cleaving the building where his parents lived into pieces from top to bottom. These people, there must have been a great commotion when their parents died, why didn't they notice? Their parents have been dead for so long, why didn't they notice? Because they were also participants.

"Boom...!" Another explosion rang out as Dark Tiga punched into the adjacent building, creating a large hole. Then, with a sweeping arm, he snapped the entire building in half. But that wasn't all; the next moment, he stepped forward and delivered a low knee strike, crushing the entire building above the third floor. He had never imagined that the kung fu he learned from Wang Han would be so swift and efficient.

"It's Daigo."

"It's Ultraman Tiga."

"Did he discover that his parents were already dead?"

"Could they be here for revenge? Why at this time?"

"Weren't there supposed to be an ambush outside? Why didn't we spot it?"

The destruction of the two residential buildings and the resulting commotion naturally attracted the attention of residents in the surrounding buildings. Many of those who were awakened drew back their curtains to look, and the sight they saw chilled them to the bone like ice water.

"Run!" The next moment, seeing that dark, oppressive, and enormous body, the people who had regained their senses were terrified and desperately fled their homes. They didn't even bother to put on their clothes. Because they knew they didn't have much time, and they knew perfectly well what they had done.

Hearing the surrounding commotion, including voices that recognized him and those that indicated the death of his parents, Dark Tiga's rage burned even brighter. A denser darkness began to envelop the sky, and a black energy sphere coalesced in his free right hand. Without hesitation or pity, Dark Tiga poured the dark energy sphere into the earth.

"Boom boom boom boom boom boom...!" The next moment, a series of explosions rang out in the community. The buildings, greenery, and soil in the community were blown into pieces and scattered everywhere, accompanied by scarlet blood and severed limbs.

"Whoosh whoosh whoosh..." A sound like an air raid siren rang out outside the residential area, and lights in the surrounding area turned on one by one. Searchlights shone from the surrounding residential areas and high-rise buildings. From the surrounding buildings, Self-Defense Force soldiers also poked their heads out, taking out rocket launchers and machine guns.

"What is this?" The soldiers who poked their heads out were stunned as they looked at Dark Tiga, who was wreaking havoc in the neighborhood. The terrifying and oppressive aura emanating from Dark Tiga made their hearts pound, and immense fear enveloped them.

"You all deserve to die!" Looking at the searchlights and the Self-Defense Force soldiers peeking out from the surrounding buildings, Daigo instantly understood what was going on. A silent roar resounded in Dark Tiga's heart. He raised his hands, and the next moment, a gray-purple beam of light shot out from Dark Tiga's crossed hands, sweeping across all the houses with searchlights lit up.

"Boom!" A terrifying explosion rang out like thunder in a stormy night. A beam of dark light swept across, plunging the once-illuminated night sky into darkness once more.

"Whoosh...!" After doing all this, Dark Tiga carefully placed the bodies of his tragically murdered parents in his hands and flew into the distant sky, the direction of which was Wang Han's experimental base.

Wang Han once told him that the highest achievement in traditional Chinese medicine is to revive the dead, restore flesh to bones, and concoct elixirs of immortality. Over two thousand years ago, there were figures who could concoct elixirs of immortality.
