Jade Turtle carried Izuku gently in his arms. Though he felt the weight of fatigue pressing upon him, he remained steadfast, determined to let the boy rest properly. As they traveled, Nooroo quietly returned to the locket brooch, his tiny form glowing faintly before disappearing inside.
Leaping from rooftop to rooftop with incredible speed, Jade Turtle traversed the city in moments. Within minutes, he arrived back at his humble shop.
Carefully, he laid Izuku on the kang, ensuring the boy was comfortable, and left the Butterfly Miraculous resting safely on his chest.
Once satisfied, Jade Turtle released his transformation, reverting to his normal form.
"You're not taking the Miraculous, Master?" Wayzz asked curiously, his small green body hovering beside Wang Fu. "I thought you would, considering how dangerous it is."
"It is dangerous," Wang Fu admitted, settling himself cross-legged before the Miracle Box. "But Nooroo seemed content, and the boy used its power for good—just as it was meant to be used. With the Butterfly Miraculous in the right hands, there's no need to release the Ladybug and Cat Miraculouses… not yet, anyway."
"But the Peacock Miraculous is still missing, Master," Wayzz reminded him gently.
"That's precisely why I said not yet, Wayzz," Wang Fu replied, his gaze drifting toward the window where the morning sun poured through. "There will be chaos soon enough."
Wayzz tilted his head. "So… what will you do with that boy, Master?"
Wang Fu folded his hands, deep in thought. "Perhaps… I'll adopt him. I've always wanted a grandchild of my own."
Wayzz blinked in surprise. "Adopt him? Why is that?"
"Well," Wang Fu began, his voice calm yet thoughtful, "Nooroo mentioned that the boy is from another multiverse. That means he doesn't exist in this world—he's an anomaly, without a counterpart here. If I leave him as he is, the authorities will certainly take notice. I'll have to create proper documents so he can live here legally. And I want to enroll him in school. He's still a child, after all."
"That's a fair point, Master," Wayzz agreed, flying toward the door of the room. Peeking inside, he saw Nooroo hovering near Izuku, gently comforting him with a look of quiet worry. "It's really nice to see Nooroo again," Wayzz said softly. "I can't wait to tell the others."
"You may tell them now, Wayzz," Wang Fu said, his tone kind but firm. "It'll be some time before the boy wakes up. I'll be busy integrating him into society properly."
Wayzz nodded and flew into the Miracle Box, ready to share the news with the other kwamis, while Wang Fu remained at his desk—already planning the next steps to ensure the mysterious boy's future in this world.

After many hours of deep, undisturbed rest, Izuku finally stirred awake in the afternoon. The soft warmth of sunlight filtered through the window, brushing across his face.
Blinking his eyes open, he quickly realized he was no longer on a rooftop. Instead, he found himself lying on a comfortable bed inside a quiet, modest home.
The air smelled faintly of tea and aged wood, a peaceful contrast to the chaos he remembered before passing out. It was no wonder he had slept so well.
Cautiously, Izuku sat up, his mind immediately on alert.
He glanced around the unfamiliar room, unsure whether the person who had brought him here was friend or foe. "Nooroo… where am I?" he whispered, his voice still hoarse from exhaustion.
Nooroo emerged from the brooch in a soft shimmer of light, giggling warmly. "Don't worry, Master. We're in the home of Master Fu—the Guardian of the Miracle Box I told you about!"
"Master Fu?" Izuku asked, frowning slightly. "You can say his name now?"
"Of course," Nooroo replied cheerfully. "That's because he's already met you! He's the one who brought you here after you fainted."
The kwami fluttered a little closer, his tone encouraging.
"You should go out of the room, Master Fu is expecting you."
Izuku took a deep breath to steady himself, nodding slowly. "Okay."
He stepped out of the room, his heart beating fast. The house was quiet, bathed in the soft orange light of the setting sun. In the center of the room, he saw an elderly man sitting cross-legged on the floor, eyes closed, lost in deep meditation.
Izuku hesitated, unsure of what to do, then awkwardly sat down across from him, folding his legs in an attempt to be respectful. He stayed perfectly still, afraid to interrupt, though his nervous energy betrayed him.
Beads of sweat formed on his forehead, and his hands trembled slightly in his lap.
After a few moments, the old man opened his eyes. His calm yet piercing gaze fell upon Izuku. "So, you must be the new wielder of the Butterfly Miraculous," Wang Fu said, his voice soft but authoritative. "Izuku Midoriya, correct?"
Izuku's eyes widened in surprise that the man already knew his name.
Wang Fu continued, "Nooroo has already told me about you—about how you come from another world, and how you freed him from being used for evil purposes."
Izuku chuckled awkwardly, rubbing the back of his neck. "That last part was kind of an accident. I didn't really mean to land at that mansion… I don't even know if I was meant to find it."
"Fate works in mysterious ways," Wang Fu replied knowingly, a hint of nostalgia glimmering in his tone. "I would know that better than most."
He folded his hands atop his knees and leaned slightly forward.
"I understand that you're not ready to talk about what happened in your world—or how you came to be here. So, instead, let me ask you this: how did you feel when you first used the Miraculous?"
Izuku fell silent at the question. A wave of emotion stirred inside him—sadness, gratitude, guilt, and hope all tangled together.
He was thankful that Master Fu hadn't pressed him about the destruction of his world. The memory still hurt too much.
His home… his mother—all gone, erased in an instant.
If it hadn't been for last night—the thrill of saving lives, the pure joy of being a hero, even just for a moment—he might have been swallowed whole by despair.
Perhaps, if things had gone differently, he might have actually listened to Kacchan's cruel words and jumped from that rooftop.
"It saved me," Izuku answered simply. His quiet but resolute tone caught both Wang Fu and Nooroo by surprise. "Because of this Butterfly Miraculous, I was able to become a hero. I was always treated like a weakling, constantly underestimated… yet when I helped people—when I gave power to those who were powerless like me—it felt incredible."
He paused, his voice trembling as he fought back a tear.
"And most of all, it helped me stay calm. It stopped me from losing myself… when I became the sole survivor of my world."
"I'm so sorry to hear that, Izuku," Wang Fu said gently, his expression softening.
He hadn't expected their conversation to turn so somber.
"Tell me… why did you want to become a hero in the first place?"
Izuku's expression brightened slightly as he thought back to his childhood. "Because of All Might—the Number One Hero of Japan, and my favorite hero of all time. No matter how grim things became, he always smiled. His smile and his courage gave people hope that everything would be okay. He's the greatest hero in Japan—probably in the entire world."
"Possessing great power, yet using it responsibly rather than selfishly or cruelly," Wang Fu mused with admiration. "That's rare. I can see why you look up to this All Might. And because of his example, you wish to bring hope to others as he did—to make them smile in the face of despair. Is that right?"
"You could say that," Izuku murmured, lowering his gaze with a faint, wistful smile. "In my world, eighty percent of the population has a Quirk—that's what we call superpowers. I didn't inherit one from my parents. I was born Quirkless. Everyone mocked me for dreaming of becoming a hero… even my childhood friend."
Wang Fu nodded thoughtfully. "Being a hero is not about possessing power—it's about possessing the heart of one. Power alone cannot make a hero if the heart behind it is empty. You may not have been born with a 'Quirk,' but last night proved you already had the heart of a true hero. And that," he said with quiet conviction, "is more than enough. You don't need a flashy gift to be a hero."
Izuku chuckled softly, trying to hold back the tears welling in his eyes. "Thanks, Master Fu."
He reached into his pocket and carefully took out the locket brooch, holding it in both hands.
"I suppose you'll want this back. I only used it because I had to save people. I wasn't chosen properly."
"Master," Nooroo interjected quickly, his voice filled with warmth and loyalty. "You are already a perfect master. I've told you before—you were chosen. Chosen by me. You are worthy of the Butterfly Miraculous."
"Nooroo is right, Izuku," Wang Fu agreed, his tone calm but firm. "The Butterfly Miraculous now belongs to you. It's not only the Guardian's duty to select a wielder—the kwami themselves have the right to choose as well. And since Nooroo wishes to stay by your side, you've already been chosen in every way that matters."
Izuku looked down at the brooch, his reflection faintly mirrored in its polished surface. "It still doesn't feel like I deserve it," he admitted. "I just arrived in this world, and now I'm holding something so powerful—something that was once used for evil. It doesn't feel earned."
"You fear using it for evil," Wang Fu said gently, "but there's another fear inside you, one you haven't named yet."
Izuku tilted his head slightly, confused. "Eh? What do you mean?"
"The fear of being unable to save anyone," Wang Fu answered, his voice carrying a quiet weight that struck Izuku deeply. "That's the fear that drives you, isn't it? You're terrified that no matter how strong you become, it still won't be enough to protect the people you care about."
Izuku's lips trembled slightly, but he nodded. "Yeah… I guess that's true. I was just a Quirkless kid yesterday, and now I have this power—something not even a Quirk, but just as strong. It's… overwhelming."
"You'll do great things with it, Master," Nooroo said reassuringly, his tiny wings fluttering with excitement. "Last night proved it. You will become a great hero—Mightyfly."
"Mightyfly," Izuku repeated with a small laugh. "I can't believe I actually came up with that name."
"It suits you," Wang Fu said with an approving smile.
Then his expression grew more serious.
"Now, onto something important. Do you have anywhere to stay, Izuku?"
"Huh? Oh, uh… no," Izuku admitted sheepishly, rubbing the back of his neck. "I just arrived in this world. I'm not even registered anywhere—I don't exist in the system. I'm basically… a nonexistent person."
Wang Fu's smile remained warm and reassuring. "Don't worry, Izuku. I've already taken care of that. You're part of the system now—you have a legal identity in this world."
"What? Really?" Izuku's eyes widened in disbelief.
The weight of uncertainty that had been pressing on him suddenly began to lift.
"You mean… I'm not some kind of illegal alien anymore? Literally. How did you even do that? And why?"
"I can't reveal all my secrets," Wang Fu said with a playful glint in his eye, "but here's a hint—I needed a miracle." He winked knowingly, and Izuku instantly understood what he meant.
Then, with a calm gesture, Wang Fu pulled out a neatly folded set of papers.
"And here's one last surprise."
Confused, Izuku took the papers from him and unfolded them.
His breath caught in his throat as his eyes widened in shock. "Wait—these are… adoption papers?"
"That's right," Wang Fu said softly, his tone filled with genuine warmth. "You don't have any family left, do you? That makes you an orphan. And I can't stand the thought of a child like you wandering the streets, fighting so hard to become a hero without a home to return to. It doesn't sit right with me."
He rested his hands on his knees, his eyes kind but firm.
"If you accept, I'll take you in as my adopted grandson. You won't have to face this world alone, Izuku. Not now. Not ever."
Izuku's lip quivered as emotion surged through him. He had been prepared to live alone in this strange new world, convinced he'd lost everything that once gave his life meaning.
His mother's death still lingered painfully in his heart, a wound that time had yet to even begin healing.
He thought he would never have a family again—yet here was this kind, elderly man, offering him not just shelter, but a place in his heart.
"I understand if you're hesitant," Wang Fu continued gently, his tone fatherly. "Your mother's death is still fresh, and I know this must seem sudden. You might even think I'm doing this because of the Butterfly Miraculous—but that's not the case."
His gaze softened even further.
"Even if you weren't chosen by Nooroo, I would still adopt you. You've lost everything, and you deserve a home. I'm helping you not out of obligation, but because it's simply the right thing to do."
Izuku could no longer hold back his tears. His voice broke as he whispered, "Thank you…"
His body trembled as he bowed his head, clutching the adoption papers tightly.
For the first time since his world had vanished, he felt something warm—something he thought he had lost forever: belonging.
—
A few hours later, Izuku sat quietly outside Wang Fu's shop, watching the amber sky fade into twilight. Everything that had happened since he arrived in this new world felt like a whirlwind—his home's destruction, meeting Nooroo, becoming a Miraculous wielder, and now… gaining a family again.
It was almost too much to process.
The weight of it all pressed against his chest, but instead of despair, he felt determination.
He still didn't fully understand what the mysterious being known as Unknown meant by destiny, but if this—meeting Nooroo, becoming Mightyfly, being given a second chance—was part of it, then he was willing to accept it.
After all, his old world was gone.
There was no going back.
All he could do now was move forward.
"Are we heading out soon, Master?" Nooroo asked curiously as the last rays of the sun slipped below the horizon. "Or shall we call it a night?"
"There's still a lot of crime out there, Nooroo," Izuku replied, rising to his feet and clenching his fists with quiet resolve. "I have to help those people. Mightyfly has to help them."
He glanced up at the darkening sky, determination burning in his eyes.
"Besides… it keeps me from thinking too much about what happened to my world."
Nooroo nodded, understanding his master's pain all too well. "Very well then, Master," he said with a proud smile. "You know the magic words."
Izuku took one last glance around to make sure no one was watching, then drew in a deep breath. His eyes gleamed with resolve as he raised the Miraculous.
"Nooroo! Light wings, rise!"
