"Gotcha! Hahaha!" Roy grinned triumphantly.

Food was a powerful tool.

Thanks to his stash of treats, subduing Est had been a piece of cake.

Come to think of it, he'd won over Akame and Kurome with food too.

'I need to stock up on more snacks', he thought.

The girls, however, were dumbfounded. He'd subdued the Sword Spirit so easily?

"Hey! I could have done that!" Mine rolled her eyes.

"Sure you could. You'd be sliced to ribbons before you even got close," Chelsea teased.

Mine glared at her. Chelsea had a point, though. Without being able to withstand Est's attacks, there'd be no chance to offer her any treats.

Roy and Est completed the Devil reincarnation ritual. Est became his Queen, her power surging to peak Ultimate-class, almost Maou level.

"Congratulations, Roy! Another powerful servant," Rias said, a hint of envy in her voice.

"Don't worry, Rias. I have my eye on some candidates for your peerage. You'll be pleased," Roy assured her.

"Really?" Rias's eyes lit up.

"Really. Trust me." Roy nodded seriously.

Rias, thrilled, gave him a quick kiss on the cheek.

"Roy, who is she? Can I kill her?" Est, munching on cake, looked at Rias with a blank expression.

'Uh oh. Looks like Est is the jealous type,' Roy thought. This could be a problem.

"Est, be nice," he said, patting her head.

"Mmm… Feels good!" It was Est's first head pat, and she seemed to enjoy it. Roy chuckled. She was so easy to please.

They set off again. They were close to the Five Elemental Lords Alliance now.

❁❁❁❁

Within half a day, they arrived at their stronghold.

They approached openly, their presence immediately detected. The five Elemental Lords and their spirit armies surrounded them.

Roy waited calmly, arms crossed.

"Dark Elemental Lord, you dare show your face here? You think winning once makes you invincible?" The warrior with the burning sword, the Fire Elemental Lord, Volcanicus, roared.

"The Otherworld Darkness has corrupted you. You will die a madwoman," the giant wielding a massive hammer, the Earth Elemental Lord, Lode Gear, said grimly.

"Hmph. I have mastered the True Darkness. Submit now, while you still can," Ren Ashdoll sneered.

"Mastered the True Darkness?" The Elemental Lords were shocked.

Ren showed no signs of corruption. If she truly had mastered the True Darkness, there was no need to fight.

Their alliance had been formed to prevent Ren from opening a gate to the Otherworld after being consumed by the darkness.

The Elemental Lords fell silent.

"Dark Elemental Lord," the old man with the scales and staff, the Holy Lord, Alexander, said, "if you are no longer corrupted, we have no reason to fight."

"Whether you fight or not is no longer your decision. You will either submit or be destroyed," Roy said coldly.

"Who are you?"

"He is my master. My savior!!" Ren Ashdoll answered for him.

The Elemental Lords glanced at Roy, sensing no threat from him, dismissed him.

"Dark Elemental Lord, even with the True Darkness, you cannot defeat us all. Let us return to peace," the woman holding a water jug, the Water Elemental Lord, Iseria Seaward, said softly.

She was the most gentle of the Lords.

"You still don't understand the difference in our power," Ren said, ready to attack.

Roy stopped her. "I'll handle this."

Ren nodded obediently.

"Est!" Roy called.

"Yes!" Est, who had been enjoying her dessert, handed it to Alice and transformed into the Holy Sword that Slays Demon Lords. She flew into Roy's hand.

Roy grinned, walking towards the Elemental Lords. They recognized the sword.

"That Sword Spirit! This is troublesome!"

"But he won't defeat us so easily."

"I'll fight him!"

The Elemental Lords conferred, and Volcanicus stepped forward.

"I will be your opponent!" he declared, pointing his burning sword at Roy.

"I suggest you all attack at once," Roy said, smirking.

"Arrogant!" Volcanicus roared, charging with his flaming sword.

Roy shook his head and met his charge.

Clang!

Volcanicus's sword shattered. Roy's blade rested against his neck.

"Impossible! I… I lost." Volcanicus stared at his broken blade in disbelief.

He'd been defeated instantly. It was to be expected, though. Est, a peak Ultimate-class spirit, could easily cut through any ordinary sword.

"Anyone else want to try?" Roy asked, looking at the other Elemental Lords.

They exchanged glances. Alexander, the old man with the scales and staff, stepped forward. "If you want us to submit, you must defeat us all." Alexander was the most ambitious of the Elemental Lords.

In the original story, he had manipulated Solomon, who inherited Ren Ashdoll's power, into becoming a Demon Lord and conquering the human world.

However, he wasn't corrupted by the Otherworld Darkness yet and was still relatively sane.

"Fine. Come at me, all of you," Roy said, holding Est's sword and smirking.

The four remaining Elemental Lords attacked simultaneously, unleashing a barrage of elemental magic.

Roy casually dispersed the magic with a single swing of his sword. The gap between Ultimate and Maou was too vast. They were no match for him.

"What?!"

"Impossible!"

"All four Lords defeated in an instant?!"

"He's a monster!" The high-ranking spirits watching were in disbelief.

"We submit!" The Elemental Lords knelt before Roy. As newly born beings, they were straightforward.

Defeated, they surrendered without hesitation.

Roy smirked.

"Good. Gather your high-ranking spirits."

He led the girls towards the Elemental Lords' stronghold.

The Lords assembled their high-ranking spirits within the temple. Roy was waiting.

"Alright, choose your spirits," he told the girls.

"Will they agree?" Akeno asked.

"With the Elemental Lords' orders, they should. But it's best if you can defeat them first." Elemental Spirits were easier to contract now, unlike in the original story where they refused to form contracts with men.

The only male Elemental Spirit user had been empowered directly by Ren Ashdoll.

Even with women, the spirits were picky, only choosing those with pure hearts and bodies.

The girls nodded and began choosing their spirits.

Esdeath, however, approached Roy. "Roy," she said with a smile, "can I have her?" She pointed at Iseria Seaward, the Water Elemental Lord.

'Of course, Esdeath. Only an Elemental Lord would catch your eye,' Roy thought.

"Sure." He nodded.

"I will not submit to a weakling," Iseria Seaward, clutching her water jug, said, looking down at Esdeath.

"Indeed. The strong do not bow to the weak. Let us see who is weaker, then." Esdeath smirked, drawing her rapier.

"I accept your challenge," Isaria said.

"Follow me." She led Esdeath away to find a suitable battleground.

Rias, inspired by Esdeath, felt a surge of pride. She couldn't be left behind.

She had to catch up. She decided to contract an Elemental Lord as well.

She looked at the remaining Lords. An old man, a giant… no women. She wouldn't contract a male spirit.

Rias went to Roy, clinging to his arm. "Roy, I want an Elemental Lord too! Help me!"

"An Elemental Lord, huh? Well…" Roy thought for a moment.

There had to be other Ultimate-class spirits in the Elemental Spirit World, like Est. They were just harder to find.

He turned to the remaining Lords. "Do you know any other powerful spirits like Est?"

They looked at each other. Alexander spoke. "There is a powerful Demonic Spirit said to have been born in the east."

"A Demonic Spirit?" Roy frowned. Demonic Spirits were mindless and difficult to control, especially a Ultimate-class one.

"Roy, I'll try," Rias said, her voice firm.

"Alright. We'll go and see."

Roy gave the girls some instructions, then opened a teleportation circle. He and Rias vanished, leaving Ren to protect the others.

Est, clever as ever, transformed into a sword mark and attached herself to Roy's arm.

They arrived on a mountaintop in the east. The scenery was drastically different.

The vibrant beauty of the Elemental Spirit World was replaced by a dark, swirling mist that obscured everything.

The only thing visible was the abundance of Demonic Spirits battling each other.

"Roy, this place is chaotic," Rias frowned.

"Don't worry about it. Let's go." He took her hand and they flew deeper into the mist.

The mist grew thicker, until they could barely see a few feet ahead. As Devils, however, they weren't hindered.

Finally, beneath a massive tree, Roy sensed it—an Ultimate-class Demonic Spirit.

It was a centaur, with flowing golden hair, large dark eyes, a beautiful face, a voluptuous human torso, and the lower body of a horse.

"Whoa… Those are impressive," Roy muttered.

Rias rolled her eyes.

"Roy, how do I subdue her?" she asked.

"At your current level? Beating her is out of the question," Roy said, stroking his chin.

Rias nodded. She was peak High-Class Devil. Challenging an Ultimate-class Demonic Spirit would be suicide.

But she had to defeat it to form a contract. This was a problem.

Roy's eyes lit up. He had an idea. He remembered a certain Ultimate-class Teigu he'd acquired in the 'Akame ga Kill!' world.

The Supreme Teigu, Shikoutazer. If Rias used it, she could defeat the Demonic Spirit.

Roy explained his plan.

Rias was thrilled. She hadn't known Roy possessed such a powerful Teigu.

Roy summoned Shikoutazer. The thousand-meter tall armor appeared, radiating power.

The Demonic Spirit noticed the giant and charged, a black spear forming in its hand.

"Rias, get in!" Roy urged.

"Got it!" Rias entered the control room. Roy had already explained how to operate it. It was easy.

The Demonic Spirit hurled its spear at Shikoutazer.

Rias reacted instantly, firing the Teigu's laser beam.

BOOM!

A red mushroom cloud erupted where the Demonic Spirit had been.

"Direct hit!" Rias cheered.

"Don't get cocky, Rias. That won't be enough to defeat a Demonic Spirit," Roy warned.
