My Magical Girl System

Chapter 148: Maximum Output!

The colossal plant monster towered over them, its multiple crimson flower eyes glowing with malevolent intelligence. Hundreds of thorn-covered tentacles lashed out wildly, forcing the team into a desperate defensive struggle.

Sein was breathing heavily, her flames growing weaker. "This thing... is on a completely different level!"

Sarah was flying erratically, her mana nearly depleted. "I can’t keep this up much longer!"

Lisa’s barrier was flickering dangerously as she tried to heal everyone while maintaining defense. Blood was still seeping from her side.

Andrey’s body was covered in wounds. His Damage Absorb was empty, and his regeneration couldn’t keep up with the constant damage. The boss’s tentacles were too fast, too numerous, and too powerful.

A massive thorned tentacle slammed into Sein, sending her crashing into a ruined wall. Another whipped toward Lisa.

Andrey’s eyes narrowed with grim determination.

"...We don’t have a choice anymore."

He opened the System interface in his mind and selected the team-wide option.

[Synchronized Heart Mode - Team Activation]

Warning: This will consume a large amount of Affection Points (Current: 1127)

Do you wish to activate Synchronized Heart Mode for the entire team?

Andrey didn’t hesitate.

"YES."

[Confirmation Accepted.]

[Synchronized Heart Mode - Activated!]

A brilliant multi-colored light suddenly burst from Andrey’s body. The light spread rapidly, enveloping Sarah, Lisa, and Sein at the same time.

"W-what’s happening?!" Sarah exclaimed.

Sein’s eyes widened. "This feeling...!"

Lisa’s expression softened in awe. "The synchronization..."

All three of them began to glow intensely.

Transformation Sequence....

Sarah’s pink dress blazed brighter than before, its soft hue intensifying into a radiant glow. Golden accents woven themselves along the hem and bodice, while glowing heart motifs materialized across the fabric, pulsing gently like a living heartbeat. Behind her, massive pink wings made of pure energy unfurled, their feathers shimmering with warmth. Her power surged dramatically, filling the air around her with a loving yet undeniable force.

Beside her, Lisa underwent her own transformation. Her mint-green outfit shifted and reshaped into a more elegant, flowing form. Flowing ribbons of light extended from her sleeves and waist, dancing gracefully as if moved by a gentle breeze. Above her head, a soft, translucent halo appeared, casting a serene glow over her face. She looked less like a fighter and more like a celestial guardian.

And then there was Sein. Her crimson battle dress ignited with golden flames, the fire climbing from the edges of her skirt to her collar. The red of her flames transformed into a majestic gold-crimson blaze, roaring with intensity. Crystalline armor pieces formed along her shoulders and arms, refracting light like sharpened gemstones. She stood at the center of her inferno, no longer just a warrior, but a phoenix.

The three Magical Girls now stood radiating overwhelming synchronized power. Their auras blended beautifully creating a dazzling display of light.

Andrey, who remained in his normal state, stepped back slightly and shouted:

"Go! I’ll support you from here!"

Sarah grinned, her voice full of renewed energy. "This feels amazing... Let’s finish this ugly thing!"

Sein clenched her flaming fists, a savage smile on her face. "Now we’re talking!"

Lisa’s expression became calm and focused. "I’ll provide maximum support. You two can go all out!"

The colossal plant boss roared and attacked with even greater ferocity, sensing the sudden surge in power. However, the three synchronized Magical Girls were no longer the same as before.

The three synchronized Magical Girls moved with overwhelming power and perfect coordination.

Sarah rose high into the air, her pink energy wings shining brilliantly. "Let’s end this quickly!"

She thrust both hands forward and unleashed a powered-up version of her ultimate:

"Heartstorm Apocalypse – Synchronized!"

A massive swirling vortex of pink energy descended from above, tearing through the boss’s tentacles and blasting large holes in its body. The giant plant monster roared in pain as chunks of its corrupted flesh were obliterated.

Sein didn’t waste a second. With her golden-crimson flames blazing stronger than ever, she charged forward like a meteor.

"Crimson Cataclysm – Synchronized!"

She slammed into the boss’s main body with explosive force. Her flames, now empowered by synchronization, burned with such intensity that they melted through the monster’s thick armored bark. She unleashed a relentless barrage of flaming punches and kicks, each strike leaving glowing craters on the creature’s body.

Lisa floated gracefully behind them, her halo shining brightly as she supported the team at maximum capacity.

"Elysian Sanctuary – Full Power!"

A vast mint-green dome enveloped the entire battlefield, rapidly healing their wounds, restoring mana, and weakening the boss’s dark mana at the same time. She also continuously cast **Starlight Nova**, sending waves of purifying starlight that stripped away the monster’s defenses.

Even with all this power, the colossal plant boss fought back desperately.

It roared and unleashed its strongest attack yet hundreds of thorned tentacles shot forward like spears while simultaneously spraying a concentrated cloud of deadly purple pollen mixed with corrosive sap.

Andrey, who was staying back to support them, shouted urgently:

"Dodge the pollen! Lisa, barrier!"

Lisa quickly reinforced the sanctuary barrier, but several tentacles still broke through. One massive tentacle slammed toward Sein. She blocked it with her flaming arms, but the force pushed her back.

Sarah dove in and destroyed several tentacles with precise pink energy blasts, while Sein continued her aggressive frontal assault, burning everything in her path.

The boss’s body began to crack and shatter under their coordinated onslaught. Its multiple flower eyes dimmed one by one as the synchronized power overwhelmed its corrupted core.

Sein leaped high into the air, gathering all her strength into one final strike. Golden-crimson flames spiraled around her fist as she descended like a falling sun.

"Crimson Impact – Maximum Output!"

BOOOOOOM—!!!

Her punch smashed directly into the monster’s core with devastating force. A massive explosion of golden flames engulfed the entire boss. The creature let out one final, ear-splitting screech before its gigantic body began to collapse, crumbling into burning ash and withered vines.

The giant plant boss fell.

Silence returned to the battlefield.

Sein landed heavily, breathing hard but grinning. "Hah... finally."

Sarah slowly descended, her wings fading as she wiped sweat from her brow. "That was way too close..."

Lisa lowered her hands, the halo above her head disappearing as she let out a relieved sigh. "Everyone... we did it."

Andrey walked forward, looking at the three girls who were still glowing faintly with residual synchronization energy.

"Good work," he said, a rare small smile appearing on his face. "You three were incredible."

The pulsing core in the center of the square began to crack and shatter. The dark mana in the air started to dissipate rapidly as the gate began to collapse.
