"Doppelganger?" Mirajane frowned and asked. She seemed unfamiliar with the term, and it sounded like a ninja skill.
Erza was about to answer when Laxus, on the other side, demonstrated what a doppelganger was through action.
"Mystogan: Elegant Doppelganger!" Erza exclaimed softly. Suddenly, numerous sparkling mirrors appeared around her, reflecting each other. In an instant, it seemed as if countless Harpie Lady had appeared out of nowhere, creating a kaleidoscopic effect.
Mirajane, not willing to let her opponent complete the move, summoned two dark torrents from her hands. With a swift motion, the torrents, resembling whips, lashed out towards the mirrors.
Facing this formidable torrent, the mirrors shattered like fragile biscuits. However, Erza remained calm, wearing a faintly disdainful smile.
After all the mirrors had fallen to the ground in pieces, two figures identical to Erza appeared out of nowhere. They stood alongside Erza, and except for their hairstyles, they were practically identical, as if copies produced by the same module.
These two Harpie Lady were also dressed in electronic-tight suits, each equipped with the Thorn Whips and Aelol Claws. The three of them emitted an overwhelming aura, entangling like three ribbons, making it suffocating for onlookers.
"Beautiful, aren't they? My Harpie Lady Sisterss!" Erza smiled lightly, revealing a stunning face, but the beauty concealed a deadly poison.
Erza and her Harpie Lady Sisterss flapped their wings, soaring into the sky. The three of them spiraled around each other, forming a mysterious formation, and a magical formation emerged faintly.
Seeing this, Erza was surprised and exclaimed, "It's a combination magic formation!"
As she spoke, she threw out her magic cards without hesitation. They turned into a vast sea of raging flames, rushing towards the sky and scorching the air.
Mirajane also joined the assault. With clasped hands, darkness condensed and surged out from her, creating shockwaves that seemed capable of tearing through the sky. Even before reaching the opponents, a devastating aura emanated.
At this moment, the magical formation in the sky fully revealed itself. It was round with a black edge, bearing strange and unreadable characters. In the center of the formation, a vivid ice-blue firebird seemed to be faintly visible.
Suddenly, the magical formation emitted a dazzling light. Everything poured into the ice-blue firebird, solidifying its form. It became like a real creature.
"Harpie Lady: Phoenix Formation!"
The ice-blue firebird dived down, carrying a destructive aura, and collided with the overwhelming sea of flames. When fire met the ice-blue firebird, it was as if a mouse had encountered a cat. All the flames were broken apart, creating an untouched realm around the firebird.
Following this impact, Mirajane's shockwave crashed into the firebird. A deafening roar echoed, as if a red-hot iron ball had been thrown into cold water. Eventually, it burst apart, releasing a terrifying shockwave that swept in all directions.
"Quite impressive, to withstand that attack~" Erza's calm expression, like an adult praising a child, made everyone furious with her dismissive tone.
Elfman leaped up and threw a punch with unmatched force. After transforming his entire body into a panther-man, his speed had far surpassed his previous capabilities. The perfect combination of strength and speed made this attack seemingly unavoidable.
However, there was no need for the Harpie Lady Sisters to evade. Their strength, when combined, was beyond comparison to the past.
Each of them kicked out a beautiful leg. Although the strength in their legs wasn't extraordinary, they seemed to have a connection that aggregated the power, forming a massive phantom claw. With unstoppable force, they attacked Elfman.
Elfman's expression changed, and he roared suddenly. His arm thickened instantly, and without reservation, he struck against the phantom claw with his fist. The power of his punch even caused shockwaves.
With a loud 'boom,' the phantom claw disintegrated into countless shadows, resembling falling leaves. After this heavy punch, Elfman's figure descended, and Erza chuckled. The Harpie Lady Sisters immediately formed a triangular formation, and shiny orbs appeared on their chests, emitting dazzling lights. Thunder threads emanated from these orbs, creating a terrifying atmosphere.
The orbs connected with each other, forming an equilateral triangle. In the center, an 'X' character appeared.
Crackling sounds.
"Triangle Illusionary Fireworks!"
Suddenly, the 'X' character shot out a faint red energy beam, producing a howling sound as if the scythe of death was slashing towards Elfman.
Elfman, with no way to borrow momentum in mid-air and nowhere to dodge, chose to protect his vital points, intending to directly face this powerful attack.
However, Mirajane couldn't stand by and let her brother get hurt. In an instant, she blinked and appeared by Elfman's side. She kicked him in the buttocks, sending him flying far away, just narrowly avoiding the faint red beam.
Mirajane turned her head, giving a fierce stare at the Harpie Lady Sisters, releasing her anger and killing intent without any concealment.
"Why look at me like that? Isn't this a battle of life and death now?"
"Exactly! I won't let you off!" As Mirajane's words fell, her body emitted a radiant glow, enveloping her entire being.
After the light faded away, the previously revealing outfit disappeared, replaced by an extremely majestic appearance.
Gold ear protectors extended from her ears like horns, a light blue outfit tightly wrapped her entire body, highlighting her graceful curves. Her hair became long and curly, and behind her was a black cloak. She stepped on surging flames, resembling a demon king returning from hell.
Satan Soul, the ultimate form.
"Such potent magic power! Is this the result of Mirajane's training?"
"As far as I know, this is her strongest form of Satan Soul, and even I haven't seen it in actual combat!"
Erza and Elfman exchanged glances, suddenly feeling a sense that their existence might not be necessary.
Under the pressure brought about by Mirajane's transformation, even the Harpie Lady Sisters, the Strauss siblings, couldn't help but break into a cold sweat. A chilling sensation overwhelmed them, making their bodies tremble involuntarily.
Mirajane didn't speak, but she coldly stared at the Harpie Lady Sisters. Her figure disappeared abruptly and reappeared next to Laxus. With frightened eyes, the Harpie Lady Sisters watched as Mirajane's fist approached Erza's cheek.
Erza, wide-eyed with panic, gripped her fist tightly, veins popping on her forehead. Her twin claws dug into her palms as she snarled.
"Mirajane Strauss! I will make sure to tear you apart!!"
