"Yuto carries the Light Gene of the Light Successor within him," Chen Yu stated, recycling his earlier explanation to the group.
"So, Yuto can also transform into an Ultraman and fight?" Vice-Captain Tachibana exclaimed in surprise.
Having once been a host for Nexus Ultraman, Tachibana had since lost Nexus's light. If possible, Chen Yu wished to enlist Nexus for the battle, but unfortunately, that was not an option.
"Yes," Chen Yu nodded. "Dizastrous isn't just any monster but a Cosmic Calamity Beast, making the fight undoubtedly more challenging than Gargorgon."
"But Yuto is just a child. How would he know how to fight?" Captain Shin pondered for a moment before adding, "I suppose with X there, it shouldn't be a problem."
Just as Captain Shin finished speaking, an urgent message from Asuna, who had gone to space to fight alongside X and Daichi, came through: "Captain, something's wrong. X and Daichi have been sucked into a strange rift and have disappeared!"
"What?!" Captain Shin was alarmed, then asked, "What about Dizastrous?!"
"With X and Daichi gone, Dizastrous is continuing its approach to Earth. It's estimated to enter Earth's atmosphere in eight minutes!" Asuna's voice was urgent and clearly worried about Daichi.
"Let's contact Professor Yuka Shiroyama," Chen Yu suggested, shaking his head. "Yuto, as a child, doesn't possess combat skills. An Ultraman's residual consciousness will control the combat body on Yuto's behalf."
"What role does Yuto play in this battle if he can't fight?" Vice-Captain Tachibana asked.
"As a Light Successor, Yuto's role is to merge his light with that of an Ultraman, acting as a bridge," Chen Yu explained.
Under the pressing circumstances, Captain Shin decided to call Professor Shiroyama. After understanding the situation, she agreed to let Yuto fight, confident that he would be thrilled to protect Earth.
Indeed, upon being briefed at the base, Yuto eagerly asked, "Uncle, can I also transform into an Ultraman?"
"This big brother says you can," Captain Shin responded, looking at Chen Yu. "Are you willing to fight to protect Earth?"
Feeling slightly ashamed for relying on a child for Earth's protection, Captain Shin still posed the question.
"Of course, I am," Yuto replied seriously. "My mom told me, 'With great power comes great responsibility.' If I can transform into an Ultraman and fight, then I must fight the monster!"
"Well done, Yuto," Chen Yu nodded in approval. "Come with me. It's time to prepare for battle against the visitor from space."
"Okay!" Yuto agreed without hesitation.
As they left the hall, with some members following, only Tachibana and another team member stayed behind.
Outside the Xio base, Professor Shiroyama watched her son with apprehension. Understanding her son's sudden responsibility was overwhelming, but Captain Shin's assurance that Ultraman's consciousness would guide Yuto eased her worries.
Chen Yu handed the Spark Lance to Yuto, instructing, "It's your turn, Yuto."
With understanding, Yuto examined the Spark Lance, then raised it and pressed the transformation button. Simultaneously, the Ultraman Tiga statue at the pyramid ruins, already showing cracks, glowed intensely, repairing itself as Yuto transformed.
As the transformation light converged in the sky, it descended as a white beam, revealing Ultraman Tiga in front of everyone, causing amazement.
"But if Yuto is Tiga, what about you, Chen Yu? Can't you transform too?" Captain Shin inquired, concerned about their ability to defeat Dizastrous without Chen Yu's transformation.
"Don't worry," Chen Yu assured, lifting the glowing Blue Stone. "This one holds significant power."
As the stone's light flashed brilliantly, temporarily blinding everyone, a second Ultraman, the original Ultraman, appeared alongside the echoed voices.
"Still, you haven't transformed into an Ultraman," Professor Shiroyama noted, puzzled.
"Just wait," Chen Yu said, revealing a card - the Ultraman Leo Transformation Experience Card. With a flick, the Lion's Eye Ring appeared on his finger. Performing Ultraman Leo's transformation gesture, he shouted, "Leo!"
A beam of light shot from the ring, and Ultraman Leo emerged, landing on the ground. Testing his limbs, Chen Yu felt Leo's explosive power.
The original Ultraman looked on curiously, wondering if Chen Yu might be Leo's descendant.
Their amazement was interrupted as Dizastrous neared Earth's atmosphere. Chen Yu, along with Tiga and the original Ultraman, prepared to confront the giant fireball heading towards Earth.
"Let's push this creature back out of Earth!" Chen Yu urged, straining to push the fireball upward.
As they made contact, the epic battle to protect Earth from Dizastrous began.
