Hearing his encouragement, Ellis blushed, a surge of energy coursing through her.

"You're right! We won't lose!" she declared with renewed determination.

"But what do we do? The cannon fire is too intense. We can't get close," Fianna said, her brow furrowed in worry.

"We have one last resort. Create an opening for us," Claire said, her eyes fixed on the Dreadnought.

"Will it work?" Ellis asked, stepping forward to protect them.

"I don't know, but... we have to try," Claire replied.

Just then...

"Claire! I can't hold on any longer!" Fianna cried out.

Georgios, the Knight Spirit, who had been shielding them from the relentless barrage, finally faltered and collapsed.

Its form dissolved into particles of light.

Claire seized the opportunity and charged forward.

This was their only chance, while Velsaria was momentarily distracted by Georgios's defeat.

Ellis also dashed towards Velsaria from the other side.

Velsaria hesitated, unsure who to target first.

She decided to focus her fire on Claire.

Taking out the leader first was a logical strategy.

But Claire had anticipated this.

"Scarlet!" she called out.

Scarlet transformed from her whip form back into her cat form and darted through the hail of projectiles, leaping towards Velsaria.

"Useless!" Velsaria roared, swatting the fire cat away with her mecha arm.

She then turned her cannons towards Scarlet.

Although she noticed Claire approaching as well, she didn't see her as a threat without her Elemental Waffe.

Claire reached Velsaria and touched the armor on her leg.

Then, she unleashed the spirit magic she had been chanting while charging.

"O icy soul, bear witness to my rage and sorrow! Blood Sonata!"

This magic caused vibrations within the target's body, generating intense heat.

However, it required direct contact to activate, making it difficult to use in combat.

"How foolish. Your puny spirit magic can't damage my Dreadnought's armor," Velsaria sneered.

She swung her arm, knocking Claire away.

Just then...

"Ice Shot!"

Rinslet's arrow struck the spot on the armor where Claire had touched.

"I told you it was useless... What?!" Velsaria's eyes widened in shock.

"It seems... it wasn't entirely useless," Claire said, wiping the blood from her lips.

"Destruction through rapid temperature change... so that was your plan!"

"It's a basic tactic when you have both a Flame Elementalist and an Ice Elementalist on your team."

This was Claire's trump card.

Although the chances of success were slim, they had managed to create a crack in the armor.

"...!"

Crack... Crack... The cracks spread.

And then...

Ellis, riding a gust of wind, charged forward with her Windashlance.

Her attack was swift and powerful.

The spear pierced through the damaged armor and struck Velsaria in the chest.

"Damn it! Ellis!" Velsaria cried out in alarm.

"O winds of disaster, roar!"

With her spear embedded in Velsaria's chest, Ellis unleashed a powerful gust of wind.

The wind tore through the weakened armor, shattering it into pieces.

Velsaria was thrown into the air, then crashed to the ground.

"Huff... huff... huff..." Ellis collapsed, exhausted.

"Did we... win...?" Velsaria lay on the ground, seemingly unconscious.

"I..."

"Eh?"

No, she wasn't unconscious yet.

Her body started to convulse violently.

"I... can't... lose..."

"What?" Claire frowned.

Then, an unbelievable scene unfolded before their eyes.

The shattered fragments of the Elemental Waffe...

began to transform!

"Onee-sama...?" Ellis whispered, her eyes wide with shock.

"AAAAAGH!" Velsaria's scream echoed through the forest.

"What is that?!" Rinslet exclaimed.

The students watching the match on the screen were in an uproar.

Velsaria's Elemental Waffe was taking on a grotesque form.

Black armor enveloped her body, resembling a skeletal knight.

Divine power seeped from the gaps in the armor like mist, glowing faintly.

The visible divine power indicated that something was terribly wrong.

"It's a cursed seal!" Roy explained.

"Onee-sama implanted a cursed seal?!" Ellis gasped.

Why would her sister, the strongest Elementalist in the academy, resort to such a dangerous method?

The black knight roared.

Velsaria's four teammates, sensing the danger, rushed towards her.

They were the former Sylphid Knights she had recruited.

They had been hiding until now, likely following Velsaria's orders.

But...

The black knight swatted them away with a swing of its arm.

Blood splattered.

A deep gash appeared on one of the Knight's bodies.

"...?!" Everyone was stunned.

A physical injury caused by a spirit's direct attack meant that the Elementalist had lost control of their contracted spirit.

An alarm blared, signaling the suspension of the match.

"Claire, come back!" Roy called out.

"Roy, what's wrong with her?" Claire asked, rushing to his side.

"Her spirit is going berserk because of the cursed seal," Roy explained.

"I see. But what do we do now?" Rinslet asked, looking at the remains of the Dreadnought.

Black mist, like sentient tendrils, crept towards them from the black knight.

The four girls were exhausted and had little divine power left.

"I'll handle this," Roy declared, stepping forward.

He reached out with his hand.

"Est!"

"Yes, Master!"

The white spirit seal on his arm glowed, and Est materialized as the Demon Slaying Sword.

Roy effortlessly cut down the approaching tendrils, then placed a hand on Ellis's head.

"Don't worry, Ellis. I'll bring your sister back," he said with a reassuring smile.

"I believe you," Ellis replied, blushing.

...

...

Claire, seeing Roy patting Ellis's head, pouted.

"Roy, I want head pats too!" a childish voice demanded. It was Est.

"Sure, once you take care of that idiot, you can have all the head pats you want," Roy chuckled, looking at the Demon Slaying Sword.

"Roy spoils Est too much," Fianna grumbled, her voice laced with jealousy.

The other girls also seemed envious.

Roy smirked.

He walked towards Velsaria.

Countless black tendrils lashed out at him, but he effortlessly cut them down.

"RAAGH!" Velsaria roared in frustration.

She charged towards Roy, her Dreadnought now a monstrous black knight.

Roy wanted to show Velsaria the futility of relying on external power, so he didn't defeat her immediately.

He allowed her to attack with her full strength.

The Dreadnought's massive arms slammed towards him, but Roy effortlessly blocked them with his sword.

Seeing her attacks ineffective, Velsaria retreated and aimed all her cannons at him.

BOOM! BOOM! BOOM!

The fortress unleashed its full firepower.

Roy was engulfed in a sea of explosions.

The attack could devastate an area hundreds of meters wide.

Its power was comparable to a High-Class Devil's attack, but it was nothing compared to his Supreme Teigu.

Claire and the others gasped but didn't act rashly.

The students watching the screen were also worried.

"Will Roy-san be alright?"

"Hmph! The Night Demon King is the strongest. He won't be defeated."

"That woman is crazy!"

"Why aren't the instructors stopping Velsaria-senpai?"

...

Compared to the students' concern, Rias and the others were calm.

They knew such attacks were nothing to Roy.

...

A gust of wind suddenly swept through the battlefield, dispelling the smoke and dust.

Roy stood there unharmed, a calm smile on his face.

Velsaria roared in anger.

Just then, the Dreadnought underwent an unexpected transformation.

Its wrists shifted and elongated, forming a massive spear.

No, it was more like a giant battering ram.

"Roy, watch out! My sister's specialty is spearmanship!" Ellis warned.

Even Ellis's spearmanship had been taught by Velsaria. It was her most powerful weapon.

Velsaria charged, her fortress wielding the massive spear.

Countless spear attacks rained down on Roy.

But no matter how ferocious her attacks were, they were ineffective.

Roy effortlessly blocked every strike without even moving from his spot.

Claire and the others were awestruck by his power.

"It's time to end this," Roy declared with a smirk.

He vanished in a flash, reappearing before Velsaria.

The Sword pierced through Dreadnought, its silver light shining brightly.

The Dreadnought shattered.

"Velsaria, it's time to wake up. Your sister admires you, you know," Roy said softly, holding the weakened Velsaria in his arms.

Velsaria's beautiful face emerged from the shattered black armor.

"You're... that man!" she murmured, staring at Roy's star-like eyes.

Her heart, burdened by the cursed seal, skipped a beat.

Her cheeks flushed.

She averted her gaze.

"Velsaria, I understand your desire for strength, but resorting to such dangerous methods was reckless," Roy chided gently.

"You have great potential. With the right opportunities, you can definitely overcome your limitations."

Velsaria's eyes lit up.

"Indeed... I wanted to become stronger... to defeat that person..." she mumbled, referring to the masked girl with crimson hair who had defeated her in the previous Blade Dance.

"Please teach me how to become stronger," she pleaded, clutching Roy's clothes.

"No problem," Roy agreed with a smile.

Just then, Rias and the others arrived.

"Rias, I'll leave her to you," Roy said.

"Okay." Rias nodded with a smile.

She was quite pleased with Velsaria.

Velsaria was already close to High-Class Devil level.

Once she became a Devil, it wouldn't be long before she surpassed that level.

And Roy had corrected her misguided pursuit of power. She would make an excellent Rook.

Velsaria's expression fell as she saw Roy handing her over to someone else.

Roy noticed her reaction and reassured her. "Don't worry, I'll help you become stronger. I promise."

Velsaria smiled, then lost consciousness.

Her body had been ravaged by the cursed seal.

Although Roy had used Est to remove the seal on her heart, the accumulated curse had suddenly erupted, destroying her spirit veins.

It would take her years to recover as an Elementalist.

But if she became a Devil, her injuries would heal instantly, and the curse would be completely eradicated.

"Roy, will Onee-sama be alright?" Ellis asked, worried.

"Don't worry. You'll see your beloved sister tomorrow," Roy assured her, patting Ellis's head.

"Roy, thank you for saving my sister."

"It was nothing."

A few days later, Team Scarlet held a celebration to commemorate their victory and qualification for the Blade Dance.

Having defeated Velsaria's team, they were now firmly in first place.

Velsaria, after becoming Rias's Rook, was now the leader of the second-ranked team.

And the third-ranked team was "Ultimate Flash," led by Lux.

These three teams would represent the Empire in the Blade Dance.

The ship to the Elemental Spirit World would depart in a week.

The celebration was held at Roy's villa.

The spacious dining room was filled with all sorts of delicacies.

Cakes, chocolates, fruits, pastries...

Velsaria and her four teammates were also present.
