While the two Tsutsumis were locked in battle below, their clash shaking the tower from within, Bakugo was busy causing chaos and distracting the villains. The rest of the group had finally made it to the top floor. While looking for the control room, they spotted an open door.
Through the open door, Melissa, Jiro, and Todoroki removed their masks when they saw two familiar figures inside: David Shield, Melissa's father, and another scientist standing beside him, holding a metal suitcase close to his chest.
"Papa...?" Melissa's voice wavered as she took a step forward, unsure whether to feel relieved or confused.
But as they approached, the truth began to unravel as the two men talked.
The villain attack, everything they'd been fighting against, was nothing more than a staged event, orchestrated by the two men before them.
Samuel Abraham, the scientist beside David, spoke first, his tone shaking.
"The professor is only trying to retrieve what was stolen from him," he said, "Inside here is his research, a groundbreaking device that mechanically amplifies Quirks. It's still in the testing phase, but unlike Quirk-boosting drugs, this device amplifies Quirks without harming the user's body."
He glanced toward David, then continued with conviction. "The sponsors confiscated everything, the invention, the data, even the research itself. They froze his work. If the world were to learn of this, it could change the very foundation of superhuman society. Governments panicked. They pressured him to abandon the project."
Jiro's chest heaved with anger. She remembered Miyu's worried face before they left, the little girl's plea that she look after Tsutsumi, make sure he didn't get dragged into something bloody or painful again.
And now, because of these two selfish men, that promise was crumbling.
Melissa's voice trembled as she finally spoke, her blue eyes glistening with disbelief. "This is a lie, isn't it, Papa? Please tell me this is a lie."
David looked at her, really looked at her, and for the first time, she saw guilt written all over his face. "...It's not a lie," he said softly.
The words hit her harder than any explosion.
"This doesn't make sense..." Melissa whispered, shaking her head. "The Papa I know would never do something like this. So why? Why!?"
David's composure cracked. He gripped the metal casing of the device tightly, his voice breaking with emotion. "It's for All Might..."
Jiro's brows furrowed, while Todoroki's eyes widened.
David continued, desperation lacing every word. "You probably don't know, but his Quirk, it's fading. He's losing his power. But with this device... I can restore it. I can make him whole again. Maybe even stronger than before!"
He smiled weakly, a fragile, hopeful smile that didn't reach his eyes. "The Symbol of Peace... the number one hero... can shine again. He can save more lives."
Jiro stared at him in silence. Then, slowly, she spoke, her tone bitter, dripping with disgust. "So what, then? When he finally dies of old age, are you gonna dig up his corpse, stick him in a metal suit, and tell him to go save everyone again?"
The room fell deathly quiet.
All eyes turned toward Jiro. Her expression was cold, but her voice cracked with restrained anger. "Disgusting. Do you even see him as a person anymore? I thought you were friends!?"
David flinched, but he didn't stop. He clutched the device tighter, his knuckles white.
"Please... just let me give this to All Might. There's no time to rebuild it! After that, I'll accept any punishment. I've already prepared myself!"
"Prepared yourself?" Melissa's voice broke as tears streamed down her face. "You think that makes it okay? Jiro's friends... our friends... risked their lives for this!"
She took a shaky step closer. "They fought their way through hell to get here, to save people who didn't even know what was going on! And some of them... are still down there fighting right now!"
Her words barely left her lips when a loud explosion ripped through the air.
The entire room shuddered as the massive control screen flickered to life, switching to a live feed of the tower's lower levels, or what was left of them. The surveillance wing had been blown apart, debris raining down from the broken structure.
On the screen, two figures were seen plummeting through the smoke and fire, one clad in black, the other in white.
The camera zoomed in.
Jiro's heart froze. Todoroki's breath caught in his throat.
The black Rider's belt gleamed, Tsutsumi's belt.
Both of them watched in horror as the two Riders, Joker and Eternal, continued to fight, their bodies crashing through the wreckage.
"What is the meaning of this? The villains were fake… it was supposed to be an act." David murmured in disbelief, his voice trembling as the chaos around him finally began to make sense in the worst possible way.
"Of course it was an act."
A cold, distorted voice echoed through the room. Unbeknownst to them, the leader of the villain group, Wolfram, had stepped through the metal door.
He was draped in black from head to toe, his broad frame partially hidden beneath a long white coat. A metal mask covered his face, reflecting the flickering emergency lights in cold gleams.
"An act," he continued, his voice laced with disdain, "pretending to be fake villains."
Wolfram placed his gloved hand against the metal door. Sparks of white light crackled and danced along the surface, and the ground began to rumble. The metal pipes and scattered electronics on the floor twisted and lifted into the air, reshaping into sharp, deadly shards.
In an instant, they shot toward Jiro and Todoroki.
Reacting purely on instinct, Todoroki slammed his hand down, summoning a thick wall of ice that erupted between them and the attack. The shards crashed against it, scattering in a violent burst of sparks and frost.
But before he could counter, a piercing pain tore through his back, a metal pipe, sharpened to a spear's edge, had impaled him. The impact drove him to one knee, his breath catching in his throat.
"Todoroki!" Jiro cried out, but there was no time to help him. More metal spikes shot through the air toward her as she avoided them, then one shifted right toward Melissa, who stood frozen in terror.
Without hesitation, Jiro lunged forward, shoving Melissa out of harm's way, just as a spike ripped into her abdomen.
Her body hit the ground with a dull thud. Blood pooled beneath her fingers as she clutched the wound, her breathing shallow.
"Jiro! Todoroki!" Melissa screamed, tears streaming down her cheeks as she crawled toward them. Her voice broke, the sound echoing painfully in the steel chamber.
Across the room, Wolfram turned toward the man standing beside David, Samuel. "Sam. Where's the device?"
Samuel snatched the suitcase from David's trembling hands. "H-Here!"
"Sam…? Don't tell me…" David's voice faltered as realization dawned. His eyes widened in horror. "You were planning on giving the device to the villains all along?"
Samuel froze, guilt flashing across his face, but it was quickly swallowed by resentment.
"Y-you're the one who tricked me!" he spat through clenched teeth. "I served you for years, and you just let our research be buried! The recognition we deserved... The funding... Everything is gone! Everything we built turned to nothing!"
His voice cracked. "If I don't get something out of this… then all those years were a waste!"
Wolfram chuckled darkly. "Here is the reward I promised you."
Without hesitation, he raised his gun and fired. The shot echoed like thunder in the enclosed space. Samuel fell instantly, a single red hole marking his forehead.
David rushed toward the suitcase, but Wolfram fired again. The bullet tore through David's shoulder, spinning him to the ground.
Wolfram's masked face tilted slightly, his voice calm yet venomous. "It's no use. No matter what reason you had, you've dirtied your hands with evil deeds. Whether we're fake or real, the crimes you've committed won't disappear."
He crouched and picked up the suitcase, smiling behind the mask. "You're the same as us now. Just another monster born from greed."
Before he could finish his sentence, a massive wall of ice erupted between them, jagged and cold, glinting like crystal knives.
Todoroki stood tall, frost covering his back like armor. Despite the wound, his eyes burned with determination. He reached out, manipulating the ice to drag the wounded David toward him.
"Melissa!" Todoroki shouted. "Remember the plan!"
His voice jolted Melissa out of her daze. She wiped her tears and nodded, sprinting toward the control room.
"Don't let her escape!" Wolfram barked.
"Yes, sir!" His men shouted, giving chase.
Todoroki moved to block him, but Wolfram slammed his hand down, the metal flooring rippled upward, forming a barrier that split the room.
The pursuing villain reached the door just as a sharp pain exploded in his chest. He looked down to see an earphone jack embedded in him.
His body convulsed; blood filled his mouth. Bones cracked and organs ruptured from the shockwave of sound that tore through him. He collapsed onto the metal floor.
Jiro leaned against the entrance, her hand pressed tightly against her bleeding stomach. Her breathing was ragged, but her eyes were sharp and focused, burned with resolve. She had masked her presence perfectly, waiting for that single, fatal moment.
"Still alive…?" Wolfram hissed. He raised his hand, and more metal beams launched toward her, only for them to be stopped midair by another wave of Todoroki's ice.
"Let's move. I've got David," Todoroki said, his voice strained.
Jiro nodded weakly, and together they ran down the corridor, dragging the injured scientist with them. Todoroki's ice spread behind them, sealing off the path with thick frozen walls as they fled.
Moments later, the facility's systems flickered. The security drones powered down, alarms cut off, and the once-locked doors clicked open. The heroes trapped outside were finally free.
While running, Todoroki places his mask back on, and his other hand creates ice to cover Jiro and David's wounds.
"Tsutsumi, this is Todoroki." He began giving a quick summary of what had happened.
Melissa's voice came through next, panicked but determined. "The villain's heading for the rooftop! There's a helicopter waiting for him!"
With the crucial information in hand, Tsutsumi didn't waste another second. His heel slammed into Eternal's chest, sending the villain persona crashing through a reinforced wall with an earth-shaking boom. Dust and debris exploded outward like a wave, clouding the battlefield in gray smoke.
Once the smoke cleared, Eternal had completely disappeared.
The entire battle between Joker and Eternal was nothing more than an act. Tsutsumi's form returned to normal as he shifted his gaze toward the helicopter flying away.
But before it could escape, a familiar blur of gold and blue came streaking upward. He could see All Might leap from floor to floor in seconds, shattering through the building like a human missile, and directly destroying the helicopter, causing it to crash back down on the rooftop.
The rooftop itself groaned and cracked, the twisted remains of the helicopter sinking into a shifting sea of metal. Then the rooftop warped and contorted into a towering metal monstrosity, an abomination of pipes, plates, and gears.
Attack Ride: Teleport!
In a burst of magenta light, Tsutsumi appeared on the rooftop. He saw All Might being forced back by a barrage of massive metal pillars, each one slamming down with enough force to shatter concrete.
Those were created by Wolfram, now using David's invention to amplify his Quirk.
The hero tilted his head, blood spilling from his lips as he tried to speak. "Young Tsutsumi? How did you-"
He didn't finish the sentence before coughing violently, nearly collapsing from exhaustion and injury.
"You've done enough, old man, let me take it from here." Tsutsumi said before pulling out the phone-like device he obtained after unlocking ten Heisei Riders. "Otherwise, your fanboys might actually try building a machine to drag you back from the afterlife just so you can keep punching villains."
Hearing Tsutsumi's sarcastic joke, All Might couldn't help but chuckle. Even in a situation like this, he didn't lose hope or show a hint of worry or fear; it was like he was saying that there is nothing to fear once he is here.
Pulling out his Form Ride: Decade card, he slipped it into the device, and the black screen came to life.
AGITO! FAIZ! BLADE! KIVA! W! OOO! WIZARD! GHOST! EX-AID! BUILD! ZERO-ONE! SABER!
"Henshin!"
Final Form Ride: DECADE!
Tsutsumi's entire form shifted into his Decade clothing, with his horns extending longer than before. A black, white, and magenta scarf coiled around his neck, emblazoned with the Rider Cards he has obtained.
The night wind howled, billowing his coat and scarf as he stepped forward.
Wolfram roared, sending house-sized metal pillars barreling toward them.
WIZARD! ATTACK RIDE: INFINITY!
The cards on his scarf shifted, all turning into Wizard: Infinity Style.
Final Attack Ride: W-W-W-Wizard!
Multiple large magic circles appear around Wolfram; Tsutsumi casually places his hand through a smaller magic circle that appeared beside him, and colossal copies of his hand erupt from the surrounding circles, each one mirroring his motion.
With a simple wave, he casually knocked away the house-sized metal pillars, much to everyone's shock.
Before anyone could react, all at once, the hands struck toward Wolfram. The impact was apocalyptic, a barrage of blows raining down like a storm of colossal fists. The ground cracked. The metal titan buckled.
Wolfram tried to scream, tried to reinforce his defense, but another wave of colossal fists descended, crushing through the metallic shell. This, in turn, also caused David's device to be destroyed.
When the dust finally settled, the rooftop was silent.
All Might stood frozen, eyes wide in awe. From the entrance, the other who had reached the scene could only stare, speechless.
Tsutsumi's Decade clothes faded, his scarf slowly dissolving into motes of light until he stood in his normal form again, smoke rising from the scorched concrete at his feet.
