The night wasn't over yet.
Leon, Midoriya, and All Might—still in his frail form—stood inside a spacious home gym.
Well, calling it just a "gym" was underselling it.
The place was massive, with high ceilings, reinforced walls, and top-tier training equipment lining the edges. The center of the room was clear, leaving plenty of space for movement.
It looked like a mix between a professional training facility and a private underground fight club—except spotless, organized, and filled with only the best gear money could buy.
There were weights, sandbags, reinforced dummies, and even a sparring ring off to the side. The walls had racks of training weapons, though all non-lethal.
It was a place built for self-improvement.
A place meant to push limits.
And judging by the looks on Midoriya and All Might's faces, it was a lot to take in.
Midoriya's jaw practically hit the floor.
"WH— LEON?! W-WHEN DID YOU— HOW DO YOU—" He flailed wildly, eyes darting from one thing to another. "This is insane! It's like a… a secret pro-hero facility! How do you even have all this?!"
Leon shrugged. "Had it for a while."
"A while?!" Midoriya repeated. "Leon, this—this is crazy!"
All Might, standing beside him, was also visibly impressed.
Despite being in his weakened form, his sharp hero instincts immediately analyzed the space. This was no ordinary gym.
It wasn't just built for fitness.
It was built for power.
Even if he didn't know Leon well, this setup told him one thing—
This kid was serious.
Very serious.
He let out a small chuckle, crossing his arms. "I must say, young Leon, I did not expect this. This is quite the impressive facility."
Leon waved a hand. "It's nothing special."
Midoriya looked at him like he'd grown two heads. "NOTHING SPECIAL?!"
Leon ignored him.
Once they had settled down, Leon leaned against a nearby table, arms crossed. His expression turned serious.
"Before we start, I need both of you to agree on something."
Midoriya and All Might straightened up, sensing the shift in tone.
"Whatever happens here tonight stays between us," Leon said. His voice was calm, but there was an unmistakable weight behind it.
"No one else finds out. Not a single soul. Not your friends, not your teachers, not even people you trust. If you don't think you can keep that promise, then we stop here."
Midoriya gulped. "R-Really? That serious?"
Leon nodded. "If this gets out, it could cause problems. Not just for me, but for everyone involved."
All Might studied him carefully. He wasn't lying.
There was something here—something Leon wasn't saying outright.
A secret.
A power he wasn't ready to reveal to the world.
All Might had been a hero for decades—he had seen people hide their strengths for various reasons. Some out of fear, some out of caution, and some because their abilities were beyond conventional understanding.
Leon… felt like the third category.
That thought alone made him curious.
After a moment, he nodded.
"Very well," All Might said. "I give you my word. This stays between us."
Midoriya, looking between them, nodded quickly.
"I-I promise too! I won't say anything!"
Leon watched them for a moment.
Then he nodded. "Alright."
Leon exhaled, rolling his shoulders before speaking.
"The reason I said I might be able to help," he began, "is because of my Quirk."
All Might raised an eyebrow.
Midoriya perked up in interest.
Leon lifted a hand, flexing his fingers. "It's called Aura."
"Aura?" Midoriya repeated.
Leon nodded. "It's a form of energy that lets me enhance my body. It can reinforce my strength, speed, endurance—basically my overall physical performance."
Midoriya's eyes lit up. "Wait, that sounds like—!"
"Yeah." Leon cut him off. "It's similar to what Quirks like Enhancement Types can do. But that's not all it can do."
All Might remained silent, listening carefully.
Leon continued. "By circulating and molding it in certain patterns, I can do things that… recreate specific phenomena."
He flexed his fingers again, letting a faint, invisible energy pulse through them.
"It's adaptable," Leon said. "It's something I had to figure out on my own, but the more I experiment, the more I can do."
That, of course, wasn't entirely true.
What he had just described was only a small fraction of his actual ability.
Everything he had said about Aura was simply a reworded description of his true power—Class Wheel.
And no one—not now, not ever—would know about that.
That secret was his alone.
Leon rolled his neck, loosening up his muscles.
"Now then…"
He took a deep breath—
And activated his ability.
Energy surged.
A shift, subtle but undeniable, rippled through the air.
All Might's eyes sharpened, his hero instincts instantly picking up on the change.
Midoriya inhaled sharply, feeling something he couldn't quite explain.
Leon closed his eyes for a brief second.
Then—
He let it flow.
An invisible force surged around Leon.
It wasn't violent or unstable—no crackling lightning, no bursts of flame.
It was controlled, yet heavy, like an unseen pressure had filled the room.
Then—
A thick mist began to form around him. It swirled, pulsed, moving in slow, rhythmic waves, almost like it was alive.
Leon knew what he was doing.
This wasn't the first time he had tried it.
[Class Wheel: Mage → Mage → Tank.]
[You have acquired the skills: Mana Missile and Mana Attunement.]
Then—
A shift.
Something clicked within him.
[A combination has been detected.]
[You have acquired the hybrid skill: Mana Drive.]
And then—
Another shift.
Something deeper.
[A combination has been detected.]
[You have acquired the hybrid skill: Mana Spring.]
Leon exhaled slowly.
The mist around him thickened, condensing ever so slightly.
And then—
The reactions hit.
Midoriya's breath caught in his throat. His eyes were wide, his brain already working overtime to process what he was seeing.
This—
This was next-level.
Leon's so-called Aura wasn't just some physical enhancement—it was something entirely different.
"It's like…" Midoriya mumbled. "It's like his body is emitting raw energy… but it's so stable, so refined…"
He took an instinctive step forward, eyes flicking between Leon's mist-covered form and the way the air itself seemed to shift around him.
This wasn't just strength enhancement.
This was something else.
Something that felt beyond normal Quirks.
All Might, on the other hand, was completely still.
His sharp hero instincts screamed at him—not in danger, but in acknowledgment.
He could feel it.
It wasn't just an illusion.
The energy flowing around Leon was real. Tangible.
And that alone—
That terrified him.
Because if Leon had something like this, something so refined, so unique, and no one knew about it…
Then that meant he had been hiding something truly incredible this whole time.
And that was unheard of.
"Leon…" All Might finally spoke, his tone more serious than before. "This ability of yours…"
Leon glanced at him.
All Might stared back, expression unreadable.
"This is the first time I've seen anything quite like it."
Midoriya nodded rapidly. "M-Me too! I mean, I know some Quirks can manipulate energy, b-but this… this is completely different! It's so… structured!"
Leon didn't answer right away.
Instead, he focused on Mana Spring.
The moment the skill activated, Leon felt it.
A strange warmth, completely different from the usual raw power of his abilities.
Most of his skills were about destruction, speed, or endurance.
But this?
This was something… else.
He could feel the way energy circulated, moving with a purpose that wasn't meant to strike or defend—but to mend.
It wasn't just expelling mana.
It was guiding it. Reshaping it.
The best way he could describe it was…
A water spring.
A never-ending source of vitality, controlled and focused.
The logic behind it was clear now.
Mana Attunement, a skill that let him connect deeper with the flow of energy.
Mana Drive, a skill that allowed him to reinforce and manipulate his own power efficiently.
And together—
They formed something capable of restoring instead of destroying.
But there was a cost.
A massive cost.
The amount of mana this required was ridiculous.
It wasn't just like pushing power into his limbs or reinforcing his body.
It was sustaining something unnatural, something that wasn't supposed to exist in this world.
'This… is probably one of the most costly skills I can use.'
Leon could already feel it—the weight of it pulling at his reserves.
If he hadn't trained his mana control to its peak, this would have drained him in seconds.
But… it was working.
Which meant—
He could use it.
And right now?
He knew exactly what to do with it.
Leon looked at All Might.
The man was still watching him, his frail form tense, waiting for some kind of explanation.
Instead, Leon took a step forward.
"I said I might be able to help you," Leon said, voice calm.
All Might's gaze sharpened.
Leon raised a hand.
"I'm going to try something," he said. "It might not work. But if it does… it could help your condition."
Silence.
All Might was clearly hesitant.
And he had every right to be.
No doctor, no specialist, no healer had ever been able to fix the damage that had already been done.
His body was permanently broken.
That was a fact.
And yet—
There was something in Leon's voice.
Something that made him believe, even just a little.
Midoriya was already on edge, practically vibrating with anticipation.
Leon, on the other hand, simply waited.
The decision wasn't his.
After a moment, All Might exhaled.
"…Alright," he said. "Do what you need to do."
Leon nodded.
Then—
He placed his hand on All Might's chest.
And Mana Spring flowed.
