It was late afternoon when Shota Aizawa stood in front of a modest two-story house in a quiet residential neighborhood.
Not flashy.
Not neglected.
Lived in.
According to official records, this address belonged to:
Kaito ——Mother: registered. Employed. Single.
No record of Ren attached.
Aizawa knocked once.
Footsteps approached.
The door opened.
A woman in her late thirties stood there — tired eyes, steady posture.
"You must be from U.A.," she said gently.
Not surprised.
Prepared.
"Yes," Aizawa replied evenly. "I'm here regarding Ren."
She stepped aside immediately.
"Come in."
The house was warm.
Not expensive.
But cared for.
Family photos lined the hallway.
Kaito at various ages.
School events.
Birthdays.
Then—
A newer frame.
Kaito.
And Ren.
Standing awkwardly beside him.
Both trying not to look like they were trying.
The date stamp at the bottom of the photo read:
July 9th — Two Years Ago
Aizawa noticed.
He sat at the dining table.
She poured tea.
Her hands were steady.
"You're investigating him," she said quietly.
"Clarifying documentation," Aizawa corrected.
She nodded once.
"He doesn't have any."
That wasn't defensive.
It was factual.
"Tell me about the hospital," Aizawa said.
Her gaze shifted slightly — not evasive.
Remembering.
"Kaito found him first," she said. "Local hospital. Emergency intake. No ID. No listed guardians."
"Injuries?"
"Smoke inhalation. Minor burns. Dehydration."
Fire.
Aizawa remained still.
"Police involved?"
"They tried," she replied softly. "No missing person reports matched. No fingerprints on file. No DNA registry hit."
"Name?"
"He said 'Ren.' That was all."
"And Calden?"
She hesitated.
"That was written on a bracelet."
Aizawa's eyes sharpened slightly.
"Hospital bracelet?"
"Yes."
"Printed?"
"No," she said quietly. "Handwritten."
Silence settled.
"He didn't remember his birthday," she continued. "Didn't remember where he lived. Didn't remember his parents' faces clearly."
"Amnesia?"
"That's what the doctors said."
Temporary trauma-based memory fracture.
Possible.
But selective.
"Why take him in?" Aizawa asked.
She met his eyes directly.
"Because no one else did."
No hesitation.
No hero speech.
Just truth.
"Kaito refused to leave him alone," she added with a small, tired smile. "Said Ren looked like someone who had already lost too much."
Aizawa said nothing.
"Legal adoption?" he asked.
"In process," she replied. "Slow. Complicated without origin records."
"Did you assign him a birthday?"
Her expression softened slightly.
"Yes."
Aizawa didn't interrupt.
"We asked him what month felt right," she said. "He didn't know. But he liked summer."
A small pause.
"So we chose July."
Aizawa's gaze flicked to the photo again.
"The ninth," she said quietly. "That was the day he was discharged from the hospital."
July 9th.
Not birth.
Rebirth.
"One month from now," Aizawa calculated automatically.
"Yes."
"Does he know it's chosen?"
She nodded.
"He doesn't mind."
That lingered.
"He just says," she continued gently, "'It's good enough.'"
Silence filled the room.
Aizawa studied her posture.
No deception markers.
No nervous deflection.
Just a woman who had made a decision.
"Has anyone come looking for him?" he asked.
"No."
"Ever."
"No."
"Has he displayed unusual behavior at home?"
She smiled faintly.
"He cooks. Cleans when anxious. Reads late into the night."
A beat.
"And he leaves the window open."
Aizawa's eyes shifted.
"You've noticed."
"He says he sleeps better with air moving."
Noted.
"Does he ever talk about before the hospital?"
"Only fragments," she said. "Fire. Noise. Someone shouting. Then blank."
Not arson accusation.
Not confirmation.
Just memory shards.
Aizawa stood slowly.
"Your paperwork is incomplete," he said calmly.
"I know."
"But consistent."
She nodded.
"He's not dangerous," she added quietly.
Aizawa paused at the door.
"I'm not investigating him as a threat."
She didn't look fully relieved.
"Then what are you investigating?" she asked softly.
Aizawa looked back at the hallway photo.
Kaito.
Ren.
July 9th.
"I'm investigating why a boy with no records exists at all."
And whether that absence was natural—
Or intentional.
He stepped outside.
The evening air was cool.
July 9th.
Exactly one month away.
Across town, at the dorms—
Ren stood at his window.
Open.
The Pulse beat once.
Slow.
Steady.
Unaware that for the first time—
A date had been written down beside his name.
