Facing King Gigachimera, which had devastated the ocean, Agul, as the Light of the Ocean, could not tolerate it!
"Is that a tsunami?"
"Have you ever seen a tsunami that can roar for thousands of kilometers?"
Everyone on the ground was stunned; the gigantic wave completely shattered their understanding of the ocean.
Agul charged directly at King Gigachimera, wrapped in seawater, aiming for its central part, with the massive wave following closely and slamming into the monster.
In the mix of water and fire, King Gigachimera's Disastar Blast was forcefully cut off, and the monster became unstable under the impact of the wave, wobbling towards the ground.
With a loud crash, King Gigachimera's body fell into the bay, and the sky-high wave followed, striking hard against it.
"This is the Light of the Ocean..."
Chen Yu and Mebius were amazed, not expecting Agul to immediately turn the tide and bring King Gigachimera down from the sky.
The three Ultramen floated side by side in the air, all looking towards the bay where King Gigachimera had fallen.
Soon, with the surging of the seawater, King Gigachimera emerged and flew back into the sky.
Facing the newly appeared silver-blue Ultraman, King Gigachimera felt a trace of fear, especially after the heavy impact of the water had caused it great damage.
Chen Yu could clearly see a dent in the middle part of King Gigachimera, obviously caused by the wave's impact.
"Has anyone else awakened their memories?"
Taking advantage of the pause before the final assault, Chen Yu asked Agul.
"No," Fujimiya's voice came from Agul, "only I have awakened my memory."
"Good, then the three of us should be able to deal with this guy."
Looking at King Gigachimera in the sky, each of its heads spewing water, Chen Yu said.
King Gigachimera, despite its huge size, had clear weaknesses: limited mobility and a lack of diverse attacks. Apart from the abilities of its composite heads, it only had the powerful Disastar Blast.
Moreover, King Golza's two large horns had already been broken, significantly reducing its combat effectiveness. Without the Hyperspace person, which was crucial for forming the middle part of King Gigachimera, the monster lacked the continuous barrage of purple light bullets that could have turned the ground to rubble.
Agul nodded, about to summon a light blade when King Gigachimera gathered energy again, unleashing another Disastar Blast.
This time, the lava-like attack wasn't aimed at the bay but directly at Chen Yu and his companions.
Agul glanced behind, noting the direction of the research institute.
Under such circumstances, there was no chance for them to dodge the attack!
"Barrier!"
As Chen Yu spoke, he was the first to extend his hands, raising an Ultraman barrier.
Mebius and Agul quickly followed, merging their barriers with Chen Yu's.
The Disastar Blast soon hit their combined barrier, dissipating into invisible particles upon contact, while the barrier's color seemed to fade.
Chen Yu felt the immense pressure from the opponent's beam, as the barrier's energy was rapidly depleting. Without sufficient energy, they would soon be overwhelmed!
"We can't hold on much longer!"
Mebius's arms trembled slightly, staring determinedly at King Gigachimera.
"Hold on, Mebius!" Chen Yu urged, "If we can't withstand this, the Ultraman brothers in the institute and all those supporting us will be in danger..."
Chen Yu left the sentence unfinished, but Mebius understood his implication.
As the people in the institute watched anxiously, they realized they couldn't escape; the attack's range was too vast, as evidenced by its effect on the bay.
South Hikari clenched her fists and closed her eyes, her memories becoming clearer. When she opened her eyes again, they seemed to shine with light.
"South Hikari..."
Hokuto Mura noticed something unusual about her and looked over.
Smiling, South Hikari said, "Hokuto, it's alright if you don't have memories from another world. Once, I left you to fight alone when I returned to the moon. Now, let me take on this battle."
With that, a rainbow light enveloped her, forming two rings in her hands: the Ultra Rings.
Although Hokuto hadn't regained his memories, he understood what was happening to South Hikari.
Nodding, he said, "Win this for us, South Hikari!"
"I'll protect everyone."
South Hikari approached the glass wall, extending her arms to the sides and then bringing them together in front of her chest.
The Ultra Rings touched, and a burst of rainbow light enveloped her, propelling her out of the institute.
As Chen Yu and his allies struggled to maintain the barrier, a horizontal slash appeared, cutting off King Hilbagon's horns.
Feeling the pain, King Gigachimera didn't cease its Disastar Blast but roared from each head.
These roars summoned a Metallium Ray from Ace.
The colorful beam hit King Golza's head, causing a devastating explosion and removing one of King Gigachimera's heads!
In pain, King Gigachimera stopped its attack, its body writhing uncontrollably.
With the beam halted, Chen Yu and his friends dispersed their barrier.
Mebius, seeing the silver-red figure in the sky, exclaimed, "Ace, brother!"
But Ace descended, revealing a female voice: "Mebius, I'm not Hokuto."
"It's Sister South Hikari!" Mebius realized in surprise.
As King Gigachimera twisted and attempted to flee Earth, Chen Yu deduced its energy might only suffice for two such attacks.
Agul took the lead in pursuit, with Chen Yu and the others following closely into the upper atmosphere.
With King Gigachimera's energy waning, now was their chance to eliminate it once and for all.
