As a Heavenly Dragon-level Evil Dragon, Tenraku's strength was greatly enhanced after he fused with Apophis's soul-made Sacred Gear.
Now, if Tenraku's vast spiritual power were to be converted into magical power, it would be comparable to the sum of dozens of Demon King-level powers, making him a top-tier being even among transcenders!
However, to advance to the next level, he needed to accumulate even more power.
Removing the armor of the Dark Night from his body, Tenraku surveyed the battlefield.
He saw Yubelluna and Semiria systematically destroying the monsters in the sea, while Rias and Sona, along with the other girls, were still nervously constructing the barrier to seal 666 (Trihexa).
In a flash, Tenraku arrived at Rias' side.
"How's the barrier coming, Rias?" Tenraku inquired.
"It's half done. We need more time," Rias replied, her voice tense as she continued to build the barrier.
Having used up a considerable amount of magic power, both Rias and the other girls were slightly out of breath, sweat dripping from their foreheads. Tenraku injected bursts of Spirit Power to replenish the girls' depleted strength, giving them some relief.
Since he didn't know anything about magic, Tenraku couldn't be of much help and could only stand guard at the girls' side.
As time passed, the barrier that Rias and her companions had built was nearing completion. However, cracks began to appear in the golden orb formed by the Sealing Treasure, indicating that 666 (Trihexa) was about to break free!
"The Sealing Treasure has reached its limit!" Tenraku warned loudly as he watched the Golden Orb pulsate as if it were about to explode.
"Just a little bit more. We're almost there," Rias exclaimed urgently, each of them trying to speed up their pace in order to complete the barrier before 666 (Trihexa) broke free from the Sealing Treasure.
"After the barrier, everyone retreat immediately!"
"Hurry!!!" Sensing something, Tenraku's expression changed dramatically as he shouted without hesitation.
Though deeply reluctant, Rias and her companions had to stop building the barrier and quickly take to the air, distancing themselves from the Golden Sphere that sealed 666 (Trihexa).
Within seconds of Tenraku and Rias' retreat, the entire Golden Sphere glowed brightly, and then...
Boom!
A deafening explosion erupted, and an unbelievably violent shockwave spread out, even causing huge waves to crash into the sea below!
"Hooooouuuu!!!"
"Ahhhhhh..."
Countless monsters and demonic beasts were swept into the sea by the huge waves. Even Yubelluna and her companions who were fighting were affected and they screamed as they were scattered by the raging currents.
"Wow, Ahhhhh..."
A group of bats gathered in the air, forming Valerie's figure. She, too, fell uncontrollably to the sea below. As she watched the countless monsters fighting in the water below, Valerie's face turned pale with fear.
But just as Valerie was about to fall into the monster-infested sea, an invisible force lifted her up and stopped her descent.
"Th-thank you, Ophis Sama, Lilith Sama," Valerie said, still trembling with fear as she watched Ophis and Lilith slowly descend from the sky.
"Protect, snacks," Ophis said with a mouthful of snacks, then flew off with Lilith to another location.
Adjusting her state, Valerie transformed back into a group of bats and scattered. Because she hadn't been studying magic for long, Valerie hadn't joined Sona and the others in constructing the barrier to seal 666 (Trihexa).
Since the beginning of the battle, she had been scattering like a bat across the battlefield, ready to use the power of her Sacred Gear to heal her companions as soon as they were injured.
Surely some of her comrades had been injured in the recent explosion, and she had to hurry to help...
"Rias, Sona, are you both okay?" In the sky, Tenraku dispelled the barrier protecting him and the others, then turned to Rias and her companions behind him and asked.
"W-We're fine, we're fine," Rias replied in a shaking voice.
The faces of Rias and her companions turned pale. What a terrible explosion! If they had retreated a few seconds later, the consequences would have been unimaginable.
Having calmed their emotions, Tenraku and the girls looked down. They saw that the golden orb formed by the seal treasure had disappeared, and the colossal figure of 666 (Trihexa) was once again revealed.
Trouble arose when 666 (Trihexa) broke free before the barrier was completed. "Akeno, Tsubaki, Rossweisse, continue building the barrier," Tenraku ordered. "Rias, Sona, you two come with me to hold back 666 (Trihexa)!"
"Yes!" Tenraku made a quick decision and the girls responded by jumping into action. Akeno and Shinra Tsubaki descended to continue building the barrier, while Rias and Sona hovered on either side of Tenraku.
They manifested the armor of the Red Dragon Emperor and the armor of the White Dragon Sovereign.
Ddraig and Albion also shifted their focus to the two girls. Meanwhile, Tenraku activated the Sacred Gear, the Iron Scales of the Berserker Dragon. Muscles bulged on Tenraku's body, tearing his clothes as an incredibly tough layer of scales formed.
With a whoosh, huge fleshy wings spread from his back.
"Rias, Sona, Tenraku!" Lavinia's voice rang out as she and Himejima Suzaku flew towards them on huge birds.
"Lavinia, Suzaku, are you both okay?" Tenraku asked, noticing the disheveled state of the two women.
"We're fine, we just got caught in the aftermath of the explosion and ended up in the sea," Lavinia replied. "Will you hold back 666 (Trihexa)? Let us help you."
Lavinia made the offer while Himejima Suzaku watched Tenraku's current form with interest.
Although their intention was to stall 666 (Trihexa) and not to engage in a fight to the death, it was still dangerous. But Tenraku didn't refuse. "Alright. Just don't get too far away from me. Stay safe," he warned.
"We will protect you," the two women said in unison, sharing a smile before nodding.
Below, 666 (Trihexa) began to move, and Tenraku wasted no time. "Let's go!" With his dragon wings spread wide, Tenraku charged forward, with Rias, Sona, Lavinia, and Himejima Suzaku following close behind.
"Haa!!!" With a long roar, Tenraku streaked across the sky like a meteor and crashed violently into 666 (Trihexa).
The Iron Scales of the Berserker Dragon was a sacred device that Tenraku had created by sealing the soul of the Berserker Dragon, Grendel.
It greatly enhanced his physical abilities and provided him with impenetrable scales, making him perfect for melee combat. Under Tenraku's impact, even 666 (Trihexa)'s massive body showed a huge indentation.
Howling in pain, 666 (Trihexa) let out a mournful cry, only to be met with attacks from Rias and her companions.
Rias and Sona unleashed massive bursts of energy, while Lavinia and Himejima Suzaku bombarded 666 (Trihexa) with their respective magic and exorcism techniques, causing explosions all over her body.
Of course, 666 (Trihexa) wouldn't stand idly by. It retaliated by raising its four massive arms to grab Tenraku and the others.
However, due to its immense size, 666 (Trihexa)'s movements were somewhat sluggish, and Tenraku and the girls easily dodged its attempts, flying around it and launching continuous attacks.
With their current strength, it was impossible to defeat 666 (Trihexa). Even though the 666 (Trihexa) before them was just a clone split from the original 666 (Trihexa), Tenraku and Rias' group had no intention of defeating it from the beginning.
They just needed to slow it down to give Akeno, Rossweisse, and the others enough time.
Boom! Boom! Boom!
The explosions continued, and 666 (Trihexa) couldn't help but roar in anger. Although the attacks from these humans and devils didn't cause much damage, the constant harassment from them began to make 666 (Trihexa) angry.
Opening his huge mouth, 666 (Trihexa) condensed a fiery red ball of energy and prepared to unleash his ultimate move.
"Rest in peace!"
666 (Trihexa)'s shockwave was no joke. Tenraku wasn't going to let it start, so he thrust out his palm and unleashed a powerful shockwave first. Tenraku's shockwave directly hit the energy ball in 666 (Trihexa)'s mouth. As expected, the entire energy ball in 666 (Trihexa)'s mouth exploded.
Boom!!!
Flames shot into the sky. 666 (Trihexa) was injured by Tenraku's energy blast, and its head became a bloody mess. Then his colossal body lost its balance and crashed into the sea.
Hundreds of monsters and demonic beasts fighting on the surface of the sea were crushed to a pulp, and the sea churned, creating a towering wave nearly a hundred meters high!
Seizing the opportunity, Tenraku immediately activated Holy Sword Creation and Demonic Sword Creation.
Suddenly, a huge Holy Demonic Sword appeared in the air, and under Tenraku's control, it flew down with a thunderous roar, piercing right through 666 (Trihexa) in the ocean.
The entire sea turned blood red, and the submerged 666 (Trihexa) let out another painful howl.
"Is it... Is it over?" Rias and her companions gathered around Tenraku, each gasping slightly as they stared intently at the sea below.
If it were an ordinary opponent, they would have died countless times over from such an attack. But what they faced now was no ordinary opponent; it was the legendary beast, 666 (Trihexa), recorded in the Book of Revelation. Tenraku knew it wouldn't be defeated by such a level of attack alone.
As expected...
