In Fairy Tail, starts with a Super Mega Gengar

Gaal remained unmoved, not responding, but instead turned his gaze to the people beside Azuma and Kain Hikaru: "The leader of the Nine Demon Gates, Kyoka. Members of the Nine Demon Gates: Franmalth, Seilah, and Tempester. I really didn't expect this, four members of the Nine Demon Gates all at once. Not bad at all."

Kyoka frowned deeply: "Human, what do you mean?"

Franmalth, somewhat impatient, said: "Let's get this over with, kill this brat. I want to see how much his soul is worth in jewels, hehe."

Gaal's lips curled slightly as he spoke in a mellow tone: "This is a Space Sealing Formation., even I can't escape. Do you think... you can escape?"

Hearing this, everyone, including Azuma, Kain Hikaru, and several demons from Tartaros, were startled, instantly becoming wary and focusing on Gaal.

Could there really be a trap here?

Or was he intentionally monitored these days in the city, secretly preparing something at night?

Considering the abilities of those low-level mages watching over him… it wasn't impossible.

So... Is this done on purpose?

Azuma and Kyoka, too, felt a heavy tension settle in. No wonder the Guild Master wanted to eliminate Gaal.

This cunning mind... As Gaal saw them slowly fall into his verbal trap and become guarded, he inwardly smiled.

With the System's means and the sustaining power of various magic potions, unless Hades suddenly appeared to destroy this place, these people stood no chance of killing him.

So, he was happy to play along, ready to test his newly developed moves.

Gaal slowly raised his right hand, watched by the wary group across from him.

Particles of Judgement emitting a strange glow spun and gathered in Gaal's palm before he flung them to his right.

Swoosh!

A subtle whooshing sound pierced the air.

A sword of light formed from the particles of Judgement appeared in Gaal's hand, a new development in response to Arceus' skill set.

He then looked at Kyoka, the leader of the Nine Demon Gates: "Requip Magic: Judgment Angel!"

As he finished speaking, a burst of light engulfed Gaal, lifting him into the air. 

In the next moment.

The light exploded.

The black magic robe Gaal had been wearing vanished. In its place was a platinum-striped battle robe with a cross emanating a divine aura hanging at his chest.

His entire appearance changed from black hair to golden locks, exuding a majestic golden light from his eyes.

The Sword of Judgement in his hand shone with endless light, and six ethereal, white wings fluttered behind him.

Kyoka's face transformed with shock, and she angrily glanced at Azuma: "This is the Space Sealing you spoke of? How is he able to use Requip Magic?!"

If he can use Requip Magic, then what about Space Magic? And moreover... What is this Requip?!

An angel?!

Are you kidding?!

How can there be such a thing as an angel?!

The rest of the demons from Tartaros also showed expressions of shock.

The threatening aura emanating from Gaal was unmistakably real; just standing there was enough for them to feel the opposition's restraint.

But an angel... Weren't they just figments imagined by terrified humans?

They've never appeared in this world before!

The demons knew they were truly created by Zeref, with the Underworld and all. Those were real.

But an angel, a descent from the heavens... How could such a thing suddenly appear out of nowhere?!

Azuma, unlike the demons, wasn't as petrified by Gaal's Requip.

Still, he was confused too and realized that the Space Sealing Formation on the trees was still intact according to his Magic Power probe: "This... I don't understand either. "Normal Requip Magic involves storing items in an alternate dimension and retrieving them during battle. That falls under space-type abilities., the sealing formation is functioning normally; he shouldn't be able to Requip... Where did his equipment come from?"

Floating in the air, Gaal spoke slowly, his tone filled with the Light's disdain for Dark: "Want to know why I can use Requip Magic within a Space Sealing? Then let me enlighten you, you lowly demons."

Gaal raised his Sword of Judgement, suddenly shouting: "Azuma! Make a move!!!"

As soon as the words fell, Kyoka on the ground was enraged and glared at Azuma and Kain Hikaru: "I knew you were up to something!!! Five Senses Deprivation!"

Kyoka, being the closest, launched a curse attack at the two, while the other demons quickly retreated, attacking Azuma and Kain Hikaru with spells. 

This unforeseen attack momentarily bewildered Azuma.

It wasn't until Kyoka's furious roar that he regained his senses, cursing the witless demon, and raised his hands to erect layers of tree walls: "Idiot! That guy played you, why would I cooperate with him?!!"

Boom!

Boom!

Boom!

Boom!

A blitz of chaotic spells rained down, bombarding relentlessly.

Even as Azuma drew Magic Power incessantly from the earth, such a burst was overwhelming. He supported the barrier with one hand and seized Kain Hikaru's shoulder with the other: "Move!!!"

Kain Hikaru obliged immediately, propelling them both into a golden flash retreat. 

The subsequent bombardment obliterated the tree wall.

Kyoka regaining composure from her earlier fury, raised her head in haste, seeing no sign of Gaal in the air.

Suddenly.

"Ahhh!!!"

A scream echoed from behind, and there was Gaal with his Sword of Judgement, piercing through Franmalth and pushing him back.

Franmalth, full of terror, the massive eye on his head trembling violently, was shouting incessantly: "It hurts! It hurts so much! Get away from me! Angel! Get away!!!! Absorb! Absorb!!!"

Confronted with an angel for the first time and pierced no less, the terrified Franmalth failed to notice that under his absorbing spell, Gaal's hair's golden tint slightly waned, revealing a hint of black, though it was quickly restored by Magic Power.

Naturally, he couldn't have those demons finding out it was all a façade.

Gaal kicked Franmalth away from his chest, severing his absorption, pulling out the Sword of Judgement with a flourish, and slowly turned to face the other demons.

Franmalth, consumed by fear, missed that maneuver; the other demons, positioned farther away, missed it even more.

They just saw Gaal swiftly pierce Franmalth, devastatingly injuring and sending him flying.
