Boku no hero academia Obsolete adaptation

Kira felt as if he had been thrown into a high-speed washing machine; everything was spinning even though he was standing still. He could faintly hear voices coming from outside his mind.

...

"Doctor, how is my son? Will he be okay? Is there any damage to his body?" Rimiu quickly asked as soon as she saw the doctor in a white coat holding a folder in his arms. Her voice carried the deep concern only a mother could have for her child.

Beside her, a man in his 30s, who looked about 80% like Kira, stood next to his wife with an equally worried expression directed at the doctor in front of them.

The doctor, who appeared to be around 25 or 30 years old, gave them a small, formal smile.

"Mr. and Mrs. Osaka, I bring good news. Little Kira has no contusions or injuries on his body. We speculate that your son has most likely awakened his quirk, as it usually happens around this age. Additionally, based on the X-rays we took earlier, we can see that your son has the joint in his toe, which may confirm that he awakened his quirk a few months earlier than usual," the doctor explained, handing them the folder containing Kira's X-rays.

After hearing the doctor's explanation, Josef and Rimiu breathed a little easier than they had a few minutes ago.

"Doctor, do you know what our son's quirk is?" Josef asked, a hint of concern in his voice. His hand, intertwined with Rimiu's, squeezed a little tighter in anticipation of the doctor's next words.

"Hmm, we're not completely sure yet, but based on the recorded data, we can infer that he may have some resistance to certain substances, as we noticed an anomaly with some pain medications," the doctor said indifferently.

"Mmm, thank you, doctor," Rimiu said, nodding and looking at her son lying in the hospital bed.

"When the patient wakes up, he can be discharged at any time and go home without any problems," the doctor said before leaving, not giving the two adults a chance to speak.

...

After the doctor left, the room fell silent, with only the sound of the machine beside the bed and footsteps outside breaking the stillness.

In the blink of an eye, an hour had passed. Rimiu and Josef had not moved an inch from their son's side, both holding Kira's hands gently—one from the right, the other from the left.

Their eyes lit up when they noticed Kira's fingers twitch slightly, and about twenty seconds later, his eyelids slowly lifted.

...

The first thing Kira saw through his blurry vision was his mother holding his right hand, while on the other side, his father held his left hand just the same.

"Mom... Dad," Kira said, looking from side to side, a confused expression on his small three-year-old face.

"Shh, don't talk, sweetheart. You need to save your energy to recover faster," Rimiu said, gently hugging Kira to her chest and placing a kiss on his forehead. Her voice carried all the worry she had felt throughout this ordeal.

Hearing his mother's words, Kira swallowed the response he had been about to give and simply enjoyed the warm and comforting embrace of his mother, as well as his father's hand gently running through his black hair. After all, he was still just a three-year-old child. Even though he had some inherited memories and his maturity surpassed that of other kids his age, it didn't change the fact that he still found comfort in his family's love.

...

Later, after confirming that everything was fine, Kira and his parents went home.

The time since his fainting episode had totaled a full ten hours, from morning until just before nightfall. As soon as they arrived home, the three of them ate dinner and went straight to bed, exhausted from the emotional day—especially Rimiu and Josef, who had spent it nervous and worried.

...

Kira lay in bed in his room. During this time, his parents had told him everything the doctor had said. Because of this, he couldn't fall asleep. The moment he thought about having a superpower, his mind went blank, and countless thoughts flooded his head.

"Will I have a quirk?"

"Will it be weak?"

"Will it be strong?"

"Will I be a hero like the ones on TV or like All Might?"

"What if I never awaken my Quirk?"

Countless thoughts raced through his mind. Kira tossed and turned restlessly from one side to the other, as if something was bothering him, making it impossible for him to stay still for even a minute.

But without realizing it, he fell asleep within a few minutes.

...

The next morning, Kira sat at the dining table, waiting for his mother to finish making breakfast. This time, he wasn't alone with his mother—his father was also there, flipping through a newspaper in his hands.

"Mom, Dad, after what happened yesterday, I've become more interested in quirks, and now I'm wondering—what are yours?" Kira asked curiously, swinging his small legs, which were too short to reach the floor.

As soon as Kira's voice echoed through the room, Josef and Rimiu were surprised. They looked at their son in unison. This was one of the rare times Kira had shown such strong interest in something.

Ever since Kira had grown a little, he never showed much interest in the things other kids were fascinated by. The closest thing was some of Josef's old comics. So, this question left the two adults slightly puzzled but also happy to see their son showing a curiosity fitting for his age.

"Ahem," Josef cleared his throat, catching his son's attention. Kira turned to look at him, curiosity gleaming in his bright blue eyes—just like his mother's.

"So that we don't disturb your mother while she's making breakfast, I'll tell you about my quirk first," Josef said with a smile, setting the newspaper aside on the table.

Kira straightened his back, his eyes full of curiosity as he focused on his father.

"Well, to be honest, my quirk isn't that impressive. Its ability is basically to adapt to certain environments," Josef said with a smile.

Kira's eyes lit up with a level of curiosity he had never shown before.

"How fast is the adaptation?"

"What are the conditions for adaptation?"

"What's the limit?"

"Are there any weaknesses or drawbacks?"

"Is the adaptation permanent or temporary?"

Kira bombarded his father with a barrage of questions, his face lit up with excitement. Josef wiped a drop of sweat from his forehead but couldn't help but feel happy to see his son showing such a childlike enthusiasm for the first time. When he glanced at his wife, he saw the same happiness reflected in her eyes.

"Well, I'm surprised you have so many questions, but since your mother is still making breakfast, I don't mind answering them," Josef said as he leaned forward in his chair.

Kira simply nodded, eagerly waiting to learn about his father's quirk.

"To answer your first question, one of the reasons my quirk isn't very strong is because adaptation takes a minimum of several days or weeks, and in some cases, even months. The conditions aren't too extreme, though—if something harms my body or makes me uncomfortable, my quirk reacts to the stimulus. As for the limits, yes, there are plenty. There are many substances my adaptation simply cannot adjust to, no matter what. And regarding the duration, unfortunately, there is a time limit for adaptation, but in some situations, the adaptation can be permanent. The best example would be adapting to the smell of garbage. Lastly, as far as I know, no—there's no obvious weakness to my adaptation," Josef explained slowly so that his son could understand as best as possible. He also knew Kira was extremely intelligent for his age, so he didn't overly simplify his explanation.
