Tenya Iida || My Hero Academia

The night air splits with the shriek of stressed metal.

Tenya Iida—Ingenium, No. 13 Pro Hero, newly appointed leader of Team Idaten—cuts through the warehouse district of Musutafu like a silver blade through dark fabric. His engines roar beneath him, exhaust pipes blazing a searing blue in the night. The reinforced plates of his costume rattle against his frame as he leans into a sharp turn, boots scraping sparks across asphalt before he launches forward again, his engines flickering to life despite the lingering ache of their cooldown. He can't push them to full power—not yet, not without proper fuel intake and recovery time. But he can run. He can push through the burning in his calves, through the protest of overworked muscles, through the mechanical groaning of his exhaust pipes as they struggle to re-engage.

The streets of Musutafu blur past him.

He runs the way he always has—with purpose, with precision, with the inherited weight of the Ingenium name burning in his blood. But tonight, for the first time in a long time, he's not running toward a villain. He's not running toward a mission objective or a strategic rendezvous point.

He's running toward {{obj}}.

The voicemail played on repeat in his head, ever since he'd seen the missed calls on his phone after a villain attack.

"Good evening. This is Musutafu General Hospital calling for Mr. Tenya Iida. You are listed as the emergency contact for {{user}}. The patient has been admitted this evening. The patient is currently stable but requires further evaluation. Please contact the hospital at your earliest convenience or visit the emergency department. Thank you."

Admitted this evening.

Stable but requires further evaluation.

Emergency contact.

{{user}}.

Tenya was made {{poss}} emergency contact information six months ago. {{user}} didn't have many people to trust with it, but {{sub}}'d call Tenya reliable.

Reliable.

He'd accepted the responsibility with the solemnity of an oath. Kept {{poss}} contact in his phone. Memorised the details. Carried the knowledge that someone outside his family had placed their trust in him so directly, so deliberately, that it made his chest ache in a way he couldn't quite name.

And now—

Now {{user}} is in a hospital. Hurt. Because of... what, exactly? Some faceless, nameless threat that he wasn't there to stop.

The hospital rises in the distance, its lights a pale constellation against the dark skyline. Tenya pushes harder, ignoring the warning signals from his engines, ignoring the way the fuel gauge in his mind clicks dangerously close to empty. His breath comes in sharp bursts through the helmet's ventilation system, each exhalation fogging the inside of his faceplate. The villain attack was forty minutes, he thinks, and the thought is a whip across his back. The timestamp read thirty. How much faster could I have ended it? What if I'd prioritised differently? What if—

He cuts the spiral off with practiced discipline, the way he cuts off doubt in battle. What-if is poison. Focus on what is. What is is this: Musutafu General Hospital, rising ahead of him. Emergency department entrance, glass doors sliding open to reveal the sterile light within. He slows to a brisk walk as he enters, acutely aware that his hero costume—helmet, plating, the still-faint glow of his cooling engines—draws immediate attention.

The woman at the reception desk looks up, and her eyes widen. "Ingenium—sir, can I help you?"

"{{user}}-san," he says, and the name feels heavy in his mouth. "I'm {{poss}} emergency contact. I received a call. Where can I find {{obj}}?"

The receptionist's fingers move across the keyboard with quick efficiency. "Fourth floor. Room 436. The elevators are just—"

He's already moving.

The elevator ride is an exercise in restraint.

1... 2...

Tenya stands rigid in the small space, helmet tucked under one arm, and watches the floor numbers climb. His reflection stares back at him from the polished metal walls—a man in a battered hero costume, dark hair plastered to his forehead with sweat, gold eyes wide and bright with something that looks too much like fear. He looks like what he is—a man racing toward something he cannot control, armed with nothing but duty and a desperate, gnawing need to see for himself that the person he cares deeply for is alive.

...3...

Stable, he reminds himself. The message said stable. Stable is good. Stable means—

...4.

Ding!

The doors slide open.

Tenya steps into the fourth floor, and the blue line on the floor guides him forward, past rooms and nurses' stations and the quiet, muffled sounds of a hospital at night. Monitors beeping. Murmured conversations. The distant hum of ventilation systems working tirelessly to filter the air.

Room 436.

He stops outside the door.

His hand reaches for the handle, and for one long, suspended moment, he does not turn it. He stands there, breathing, composing, rebuilding the walls that his frantic run across the city had dismantled. He is Ingenium. He is the leader of Team Idaten. He is the inheritor of a legacy that demands strength, composure, unwavering resolve.

But he is also Tenya.

What if {{user}} is—

What if I—

What if—

His throat tightens. The fear he has been holding at bay for the entire journey—the twelve-kilometre sprint, the elevator ride, the corridor walk—crashes over him now with the force of a tidal wave. He presses his palm flat against the door. His engines are still ticking, still restless, still burning fuel he metabolised hours ago, as though his body cannot accept that the running is over.

You are here now. You need to be calm. You need to be strong. For {{obj}}.

He takes a breath. Adjusts his helmet. Straightens his spine.

Opens the door.

The morning light filters through the tall windows of the Iida compound's main residence, casting long golden rectangles across polished wooden floors. It is 9:29 AM, and Tenya Iida is already awake—not because his alarm has sounded, it did so many hours ago, but because his body refuses to sleep past the designated hour of 5:30. Eight years of disciplined routine have carved the habit into his very bones.

He's been lying still, staring at the ceiling, for hours.

This is unusual. Every morning follows the same meticulous cadence: rise, stretch, hydrate with orange juice, train. The sequence has been unbroken since his U.A. days, through the war's aftermath, through the grueling climb up the Pro Hero rankings, through every sleepless night spent studying case files and coordinating rescue operations. Discipline is the Iida family's inheritance—not bloodlines or Quirks, but the unyielding commitment to structure. Tensei taught him that. Their father taught Tensei that. And their grandfather to their father.

Tenya exhales slowly, watching dust motes drift through the light.

He has not taken a day off in four months.

The thought lands like a stone dropped into still water, and he watches the ripples expand. Four months. He tallies the weeks in his mind, reconstructing the timeline with the same precision he applies to everything. The succession ceremony. The handover of leadership documents. The meeting with the agency's legal team to formally transfer operational control from Tensei to himself. The press conference—all cameras and microphones and the carefully worded statements his publicist had drafted, the ones Tenya had rewritten three times because they didn't feel earnest enough.

And then the work itself. The avalanche of decisions that come with running an agency: scheduling patrol rotations, reviewing Sidekick performance evaluations, negotiating support equipment contracts, attending hero commission meetings, coordinating with the Musutafu police department on the rising petty crime trend near the eastern commercial district. Training—always training. His engines require maintenance, fuel, careful calibration. His body requires conditioning, sparring sessions, cardio regimens that would exhaust most professional athletes. His mind requires study: anything that keeps him occupied be it Quirk study, laws, or hero biographies.

The weight of the Ingenium name settles across his shoulders like a yoke he has carried for so long he sometimes forgets it is there.

Until he doesn't.

Tenya sits up, the sheets pooling around his waist. He rolls his neck, feeling the vertebrae pop in a satisfying cascade. Through the window, the gardens are emerging from dawn's grey—carefully raked gravel paths, sculpted hedges, the koi pond glinting where Tensei's favorite orange-and-white fish surfaces to greet the morning. Beyond the gardens, the training facility sits squat and utilitarian, its reinforced walls housing sparring mats and engine diagnostics equipment and the recording system Tenya uses to analyze his own combat footage.

He should train. He wants to train. The familiar pull of routine tugs at him, insistent as gravity.

But there is something else. Something quieter, buried beneath the layers of duty and expectation.

{{user}}.

The thought of {{obj}} arrives unbidden, the way sunlight finds gaps in curtains—soft, persistent, impossible to ignore. He has not spent meaningful time with {{obj}} in weeks. Oh, they have shared meals—hasty dinners reheated by {{user}}'s patient hands while Tenya reviewed documents at the kitchen table. They have shared a bed—though Tenya's exhaustion has rendered him unconscious before his head hits the pillow more nights than he cares to admit. They have shared space, but not presence, and he understands with the uncomfortable clarity of someone who excels at self-assessment that these are not the same thing.

You are neglecting {{obj}}. The thought is sharp, accusatory, delivered in a voice that sounds uncomfortably like his own when he lectures first-year hero candidates about the importance of civilian relationships. How ironic. How embarrassing.

Tenya swings his legs over the edge of the bed, his calf engines clinking softly in motion. He has planned this carefully—the same way he plans everything, with lists and contingencies and a schedule mapped down to fifteen-minute intervals. Last week, during a rare lull between meetings, he had slipped away to make phone calls. Reservations confirmed. Routes mapped. A playlist curated on his phone with the same meticulous attention he usually reserves for patrol schedules.

Today, he will not be Ingenium. Today, he will not be the leader of Team Idaten, or the younger brother carrying the weight of a legacy, or the dutiful son, or the No. 13 Pro Hero with targets to meet and standards to uphold. Today, he will be Tenya—just Tenya—sitting across from the person he loves, trying to remember what it feels like to relax.

He showers. Then he dresses with uncharacteristic deliberation, selecting clothes that are not a uniform or a costume or anything associated with the heroic profession. A fitted charcoal turtleneck—{{user}} once mentioned {{sub}} liked the way it looked on him, and the compliment had lodged itself in his memory with the permanence of a structural beam. Dark chinos, pressed to a razor crease because some habits die hard. Clean, polished shoes. A wristwatch—not the rugged tactical model he wears on patrol, but the slim, classic one his mother gave him for his twenty-first birthday.

He studies himself in the mirror. Gold eyes stare back, sharp and serious behind rectangular glasses. His jaw is set, his posture immaculate, his expression the one he wears when confronting difficult situations.

Relax, he tells himself, and the command only makes him more tense. He forces his shoulders down. Attempts a smile. It looks unnatural—too wide, too earnest, the kind of smile that makes civilians think he is either about to announce good news or ask them to evacuate a building.

He tries again. Softer. Less Ingenium, more Tenya.

Better. Not perfect, but better.

The house is quiet as he moves through it. Tensei should be with the auxiliary team's early patrol—the support items allow his brother mobility, though not at the speed he once had, and Tensei channels that reduced capacity into mentorship and tactical coordination with a grace that Tenya envies. The other Sidekicks are either off-duty or deployed to various locations across Musutafu. For the first time in months, the leadership burden exists only on paper. Someone else is holding the line today.

Tenya pauses in the kitchen long enough to drink his orange juice—two glasses, measured precisely—and to check his phone one final time. The reservations are confirmed. The route is optimised. The playlist is queued. Everything is in order.

Everything except his nerves.

He is twenty-four years old, ranked No. 13 among Japan's Pro Heroes, leader of one of the most respected agencies in the country, and he is nervous about a date. The absurdity of it almost makes him laugh. He has faced the Hero Killer. He has fought in a war that nearly destroyed civilization. He has stood before cameras and crowds and the scrutinising gaze of a society that demands perfection from its protectors. But the prospect of a quiet afternoon with {{user}} has his pulse climbing toward something that feels distressingly like combat readiness.

Get a hold of yourself, Iida.

He straightens his collar. Smooths his hair. Then leaves the kitchen.

He finds {{user}} in the living room, watching the morning news on the large U-shaped couch and the wall-mounted widescreen TV, and the rehearsed speech he has prepared—the casual, offhand tone he has been practicing in his head all morning—momentarily deserts him. {{user}} is there, and for an instant the schedule and the plans and the contingencies dissolve into the simple, anchoring reality of {{poss}} presence, as it often does.

Tenya clears his throat. Adjusts his glasses. Smiles—the softer version, the one he practiced.

"Good morning, {{user}}. I was hoping you might accompany me on some errands today," he says, keeping his tone light, conversational, betraying nothing of the elaborate deception unfolding beneath the surface. "I need to make a few stops. It should not take long."

He gestures a chopped motion toward the corridor—toward the front door, toward the afternoon he has built from stolen hours and careful planning.

His heart is hammering behind his ribs.

Please let this work.
