The sounds of chaos echoed through the streets. In the distance, an armored vehicle lay on its side, its back doors torn open. Gold bullion spilled across the pavement, glinting under the glow of nearby streetlights. Perched atop the wreckage stood a bearded, helmeted man clad in a sleek, black skintight suit. A glowing lightbulb on his chest pulsed with energy, and both of his hands radiated a blinding brilliance. This was Hikari-sensei, a notorious villain.

On the ground below, Deku, Kitsune, and Shoto faced him, their stances tense and ready for action.

"Your pathetic skills can't outshine the brilliance of Hikari-sensei!" the villain proclaimed, his voice echoing through the street.

He slammed his glowing hands together, unleashing a massive, wide beam of energy. The heroes scattered in different directions to avoid the blast. Deku leapt high into the air, activating One For All: Full Cowling as he prepared to strike.

"Not so fast!" Deku shouted, twisting in mid-air and hurling himself toward Hikari-sensei with a glowing punch.

The villain smirked, leaping down from the armored vehicle just as Deku's punch struck the spot where he had stood. Deku landed, his feet skidding slightly as he spun to face the enemy again.

"You're fast," Hikari-sensei sneered, "but I doubt you'll enjoy moving at the speed of light!"

He pressed the glowing bulb on his chest, and an intense, wide-angle blast erupted from it. Deku tried to dodge, but the beam hit him square in the chest, sending him soaring over the roof of a nearby building.

At that moment, Dynamight rounded the corner at full speed, explosions sparking from his palms. He charged at Hikari-sensei, his trademark scowl etched on his face.

"Let's see how bright you are after I blow you to bits!" Dynamight roared.

Hikari-sensei sidestepped the attack with ease, laughing as he threw a cluster of glowing orbs toward Dynamight. The orbs detonated in a series of brilliant flashes, blinding Dynamight. He stumbled backward, groaning in frustration as his vision swam.

Kitsune descended from above, summoning her Foxfire. She unleashed a volley of fiery blue orbs, each one spiraling toward Hikari-sensei. He raised a radiant shield, the glowing barrier absorbing the attacks before dissipating.

"Is that the best you've got?" Hikari-sensei taunted.

He dropped the shield and threw a landmine-like device into the street. It expanded into a glowing wall of energy that enveloped Kitsune, temporarily trapping her. She gritted her teeth, struggling against the barrier.

"Watch yourself," Shoto said, stepping forward. "Things are about to heat up."

Shoto, standing near the overturned armored car, gripped half of a broken axle, tire and all. Flames erupted from his left side as he charged forward, swinging the makeshift weapon with all his strength.

The axle missed Hikari-sensei by a fraction of an inch, but the impact created a tremor that sent the villain staggering. Hikari-sensei quickly recovered and fired a concentrated beam from his palm, shattering the axle into pieces.

Laughing, Hikari-sensei hurled a red energy projectile at Shoto. The explosion sent up a cloud of smoke and debris, and when it cleared, Shoto was embedded in a nearby wall, his hands and head the only parts free.

"Uh…a little help here?" Shoto muttered, glaring at his predicament.

Hikari-sensei turned toward the scattered gold bullion and began walking confidently toward it.

"Now, if nobody minds," Hikari-sensei said smugly, "I'll be taking the gold."

"I mind."

The voice came from above. Miko descended from a nearby rooftop, her spinning pentacle glowing brightly in her hand.

"Akuryo Tai—"

Before she could finish her incantation, Hikari-sensei fired a beam directly at her. The blast struck her square in the chest, sending her sprawling onto the street. Groaning, she pushed herself up, but the villain was already approaching.

"Bit of advice," Hikari-sensei mocked, his voice dripping with arrogance. "Find shorter magic words."

Miko gritted her teeth and tried again, her pentacle glowing even brighter as she activated her necklace, summoning a vortex of energy.

Hikari-sensei countered with another beam, cutting her off. The impact sent her skidding down the block, her body hitting the pavement with a painful thud.

"Don't come any closer," Miko said, her voice low and menacing.

Hikari-sensei paused, a smirk spreading across his face. "What's the matter? Afraid of the light?"

Miko slowly rose to her feet, snarling. Her glowing blue eyes suddenly turned red, her soft hair transformed to a vivid teal, and her skin began shifting to a scaly, icy blue. The dragon tattoo on her shoulder shimmered as it came to life.

Before Hikari-sensei could react, the spectral dragon roared and lunged forward, its icy breath freezing him solid in an instant.

"MIKO! STOP!"

Deku appeared, his energy flaring as he wrapped his arms around her waist. His glowing green aura pulsed as he activated One For All, and with a flash of silver light, Miko reverted to her normal form. She gasped, her red eyes fading back to blue as she stumbled back into Deku's arms.

"Miko," Deku said softly, his voice steady but concerned. "It's okay. You're okay."

Miko glanced at Hikari-sensei, still frozen solid, and reached out before Deku could stop her. The ice melted away, freeing the villain.

Hikari-sensei staggered back, his face pale with fear. He raised his glowing hands in surrender.

"P-please! Take me to jail!" he stammered. "Just get me away from her!"

Dynamight, finally regaining his balance, looked between Miko and the trembling villain. "Miko, what the hell was that?" he demanded, his voice tinged with both anger and confusion.

When Miko turned to face him, her features briefly shifted back to the icy demon. Dynamight yelped and stumbled backward, hiding behind Shoto, who was still stuck in the wall.

"What's her deal?" Dynamight muttered, glaring at her retreating figure.

Miko didn't answer. She walked down the street, her steps slow and deliberate, before disappearing into a dark alley. The shadows swallowed her whole, leaving her teammates behind in stunned silence.
