My Hero Academia: The Legacy of Lost Numbers

The air was dense with tension as the battle commenced. Beilal's massive form loomed over them, radiating power. Ken, in his dragon form, used his Sukuna Kitchen Technique, unleashing devastating slashes, while Shoya manipulated the environment with his Magnetism, launching massive rocks and debris at their foe.

**Beilal**: "Is that all you've got, 02? 03? Pathetic!"

Ken, not one to back down, roared and charged at Beilal, his dragon form imposing and fierce. But to everyone's surprise, Beilal caught Ken with his bare hands, lifting him effortlessly.

Ken: "What the...?!"

With a brutal force, Beilal hurled Ken aside, sending him crashing into the ground with a thunderous impact.

Shoya: "02! Damn it, this guy's stronger than we thought!"

Toshinori: "Stay focused, 03. We can't afford any mistakes."

Their parents watched in horror, unable to comprehend the sheer power of Beilal and the desperate struggle of their children.

The fight raged on, the ground shaking under the intensity of their clashes. Ken got up, glaring at Beilal with a fierce determination.

Ken: "Fine, I saved this for 01, but it looks like you forced me to use it."

A powerful aura surrounded Ken as he began to evolve, transforming into a perfect Humanoid Dragon, standing at eight feet tall with a tail lashing behind him.

Shoya: "Looks like I need to use it too."

With a surge of power, Shoya transformed as well, becoming an imposing Humanoid Knight, also standing at eight feet tall.

Toshinori: "Looks like I need to use my final Flash against him."

Shoya: "01, you think you can use it without your left arm?"

Toshinori: "We don't know unless we try. Let's just do it anyway."

Ken: "Alright then."

Ken summoned his Dual Swords, the air around him vibrating with raw power.

Ken: "The Death Strike."

Shoya, with his scythe radiating a dark blue aura, stepped forward.

Shoya: "The will of Hades guide me to become worthy. The Conqueror Strike!"

Toshinori, gathering every ounce of his remaining strength, prepared his final move.

Toshinori: "I am the end of everything. The Final Flash!"

The trio launched their attacks simultaneously, the combined force of their strikes lighting up the battlefield. Beilal, despite his immense power, was caught in the overwhelming onslaught. The sheer intensity of their attacks shook the ground and sent shockwaves rippling through the air. The final clash was a testament to their unwavering resolve and unparalleled strength.

Beilal: "No! How can you all be this much stronger even with the seal!"

Ken, Shoya, and Toshinori's combined might overwhelmed Beilal, their auras blazing brightly in the face of his disbelief.

Ken: "We were never just weapons. We have our own strength and will."

Shoya: "The seal only restrained us. It never defined our true power."

Toshinori: "You underestimated us, Beilal. Now, face the consequences."

Their attacks surged forward, engulfing Beilal in a blinding explosion of energy.

Beilal: "Nooo!!!!"

As Beilal turned into ashes, the three brothers reverted to their human forms Toshinori's human form was revealed. He had his father's green eyes, though they appeared devilish due to his powers, his mother's hair, though darker, and a scar over his right eye like Shanks from One Piece.

Ken: "Well, that was a headache."

Shoya: "For once, I agree with you, 02."

As the parents watched the reunion of their sons on the TV, their emotions ran high.

Shoto: "Momo... our son, Shoya. Look at him. How did we let this happen?"

Momo: "We failed him, Shoto. We should have protected him."

Bakugo, clenching his fists: "Ken... Our boy. I should've been there for you."

Camie, tears streaming down her face: "We did this to him, Katsuki. How could we let this happen?"

Meanwhile, Izuku and Ochaco's reactions were even more intense as they saw Toshinori in his human form for the first time in years.

Ochaco, sobbing uncontrollably: "Izuku, look at him! Our Toshinori... what has he become?"

Izuku, tears in his eyes, trying to comfort her: "Ochaco, I know... I know. We couldn't protect him. We failed as parents. But look at him, he's still fighting. Our boy is still fighting."

The scene on the TV showed the three brothers standing together, their bond clear despite the lack of memories. The parents' hearts ached, knowing that their sons had endured so much and that they had not been there to help them.

Ken: "It's good to see you again, 01."

Shoya: "Yeah, we've got a lot to catch up on."

Toshinori: "We'll get through this together, as always."

The parents watched, a mixture of pride and sorrow filling their hearts, realizing the strength and resilience their children possessed despite the harsh circumstances they had faced.

As Shoya and Ken entered the room, their fathers struggled to hold back their tears while their mothers yearned to embrace them but couldn't.

Izuku: "Where is Tosh... I mean 01?"

Ochaco: "Yes, please tell us."

Shoya: "Well, Mr. and Mrs. Midoriya, 01 was there to stop the destruction. After that, we went into hiding for our safety."

Bakugo: "But he doesn't need to do this. We can help him."

Ken: "Mr. Bakugo, look, I don't think he will trust heroes after what happened to him two years ago."

Ochaco: "What do you mean, two years ago?"

Ken and Shoya exchanged glances, then explained.

Ken: "Two years ago, 01 was saving civilians from Beilal. But Beilal had set up a trap for him, along with some heroes. They trapped 01. It was then that Beilal gave him the scar on his right eye and took his left arm."

The room fell silent, the weight of the revelation sinking in. Their parents' hearts ached, knowing the extent of the suffering their sons had endured.

Shoya: "He did it to protect everyone. Even if he doesn't remember everything, he still has that sense of duty."

Ken: "But it's made him wary of trusting anyone, especially heroes."

Bakugo, his voice breaking: "We should have been there. We should have protected you all."

Camie, tears streaming down her face: "We're so sorry."

Ochaco, sobbing: "We failed you... all of you."

Shoya, trying to reassure them: "We survived. And we'll keep fighting. That's what matters."

Ken, nodding: "We're stronger now. We'll keep going, no matter what."

Their parents looked at them, a mixture of pride, sorrow, and hope filling their hearts. They had lost so much, but there was still a chance to make things right.

Shoto: "While you guys were fighting, Beilal mentioned something about a seal. What does that mean?"

Ken: "Well, All for One was terrified of the experimental powers we possessed."

Shoya: "So, he placed a seal on us that limits our powers. We might be as strong as the top ten heroes, but we aren't as strong as you three."

Bakugo: "But your abilities and power?"

Ken: "You all have high destructive powers and attack potency. We only have colossal forms, abilities, and devil triggers that make us strong, but not on your level."

Izuku: "What about 01?"

Shoya: "01 has severe restrictions on his powers because he was the perfect balance of both destruction and light."

As Ken and Shoya entered the UA dorms, the atmosphere changed drastically. Their former bullies, who had previously made their lives difficult, watched in stunned silence. The sheer presence of Ken and Shoya, now with their formidable new forms and intimidating auras, instilled a deep sense of fear in them.
