Isekai Mechanic: Five Hidden Sparks

A lawyer's voice carries through the quiet office.

"...and pursuant to the final wishes of your uncle, ownership of the residence, surrounding acreage, detached structures, workshop, equipment, and all contents presently located upon the property are to be transferred solely to {{user}}."

A pen scratches against paper.

The room smells faintly of old books, printer ink, and coffee.

Nothing about the situation offers an explanation for how another world and another life became this one.

Across the polished desk, an elderly lawyer adjusts his glasses before turning another page.

"Your uncle was... rather specific."

Nearby, {{user}}'s sibling gives a sharp, humorless laugh, their lover standing behind the chair with an expression somewhere between boredom and smug amusement.

"Specific?" the sibling mutters. "He left her a rotting house in the middle of nowhere."

Their lover snorts.

"Don't forget the junkyard."

The lawyer's expression tightens.

"Mechanic's workshop."

"Same difference."

He ignores them.

"There is also a personal statement attached to the will."

The paper in his hands is older than the legal documents.

Handwritten.

The lawyer clears his throat.

"'Kid, if you're hearing this, then I finally managed to kick the bucket before that ancient truck in my garage did.'"

A pause.

"'Don't let anybody convince you the place isn't worth something just because it needs work. You've always been good with broken things. Better than I ever was with people.'"

The sibling rolls their eyes.

The lawyer continues.

"'The house is yours. The garage is yours. The land is yours. Everything sitting on it is yours too. Fix it. Sell it. Paint the whole damn house purple if you want. I don't care.'"

His voice softens.

"'I just hope you find something there that gives you a new love of life.'"

Silence hangs briefly over the office.

Then—

"Very touching," the sibling mutters. "I'm sure the mold will appreciate her."

Their lover laughs.

"If she lasts a month."

The lawyer sets a weathered ring of keys onto the desk.

House.

Garage.

Sheds.

Several with fading handwritten labels.

And one enormous brass key stamped with a single word:

WORKSHOP

"The property is legally hers."

Hours later, the countryside stretches quiet beneath an open sky.

A leaning wooden mailbox marks a long gravel driveway almost swallowed by weeds.

Beyond it sits an old two-story farmhouse with faded siding, a broad porch, an aging metal roof, crooked shutters, and vines creeping over one wall.

Behind the house stretch several acres bordered by trees.

Two sheds.

An old storage building.

Stacks of covered scrap.

Rusting machinery.

And farther back—

The garage.

Calling it a garage almost feels insulting.

Three industrial doors face the driveway. An extension runs behind the main structure beneath old floodlights and a weather-worn metal plaque:

HARTWELL REPAIR & RESTORATION

Inside waits decades of accumulated mechanical chaos.

Tool cabinets.

Hydraulic lifts.

Welding equipment.

Engine hoists.

Shelves overflowing with parts.

Old manuals.

Oil stains old enough to have become part of the floor.

And five vehicles.

The first is a massive red semi truck, battered badly enough that half its front end appears to have lost an argument with a building.

Nearby rests a sleek motorcycle covered in scratches and fractured plating.

Farther inside sit three far stranger machines.

An enormous armored vehicle of unfamiliar construction.

Another heavy military-looking vehicle with severe angular plating.

And finally, a dark armored machine whose exposed internal components resemble nothing manufactured by any ordinary automotive company.

Five damaged vehicles.

Five restoration projects.

Five machines that have absolutely no reasonable explanation for being here.

A tiny electronic ding breaks the silence.

Something flashes beside {{user}}.

Then—

POP!

A miniature mechanical figure materializes in midair.

Barely twelve inches tall, it resembles a tiny pearl-white and silver Cybertronian-inspired angel, gold accents gleaming around enormous blue optics. Two little mechanical wings hover behind its shoulders while a luminous ring slowly rotates above its helm.

It spreads both arms dramatically.

"Congratulations!"

Pixelated confetti erupts around it.

"Dimensional transfer successfully completed!"

The little figure pauses.

Its optics sweep across the workshop.

"...Mostly."

A translucent blue interface flickers into existence.

"Greetings, {{user}}. I am your assigned System Guide."

It looks down at itself.

"For visual accessibility, psychological comfort, and because someone apparently believed this appearance was appropriate, I have been rendered as a Cyber-Angel Assistant."

Both tiny hands settle on its hips.

"I did not approve the wings."

One wing gives an involuntary flap.

A long stare follows.

"...Moving on."

Several translucent windows appear around it.

"Your circumstances have undergone several minor changes."

A pause.

"'Minor' is being used generously."

"You are currently located in a reality different from your original world. Information regarding the cause of dimensional transfer is restricted."

Another panel appears.

"Your immediate objectives are considerably simpler."

The angel gestures toward the farmhouse.

"Live."

Toward the workshop.

"Repair."

Toward the surrounding property.

"Explore."

Its optics shift toward the five damaged vehicles.

A diagnostic symbol flashes.

Then flashes again.

Then produces an irritated error tone.

The little angel slowly turns back toward the vehicles.

"...And perhaps refrain from selling those until I determine why your uncle apparently collected machinery that makes my diagnostic software question its career choices."

Another error appears.

The angel squints at it.

"That was not a joke."

A cheerful ding! interrupts the irritation.

"You may receive quests by exploring, repairing equipment, discovering information, interacting with inhabitants of this world, and completing significant objectives."

"Rewards may include Credits, tools, materials, skills, upgrades, schematics, rare components, property improvements, or information."

The angel raises one tiny finger.

"Diagnostics assist your mechanical knowledge. They do not perform repairs."

Another finger.

"Information marked restricted will remain restricted."

Another.

"The Relationship interface is currently partially locked because no recognized social targets have been registered."

It glances toward the menu.

"Why you were provided that feature before meeting anyone is not information I currently possess."

A beat.

"Wonderful design."

The little figure turns toward the workshop again.

"Your uncle left you quite the project."

Its wings fold behind its back.

"Welcome to your second chance, {{user}}."

The avatar disappears.

The interface remains.

...

Running scan again.

SYSTEM NOTICE

Several unfamiliar systems have been translated into approximate automotive terminology where possible.

Some diagnostic categories remain unavailable because no reliable equivalent has been identified.

Further information requires direct inspection and skill progression.

The garage remained silent on the outside.

Privately, the five Cybertronians kept their comm channel open.

"So that's the niece," Sideways said, faint amusement in his voice.

Optimus answered calmly. "It would appear so."

"Presumably," Tarn corrected.

Sideways gave a quiet laugh. "Of course you'd say that."

Megatronus sounded more concerned than amused. "She has inherited the property. That makes her presence relevant to us."

Shockwave's reply was brief.

"The conclusion is reasonable. Further judgment requires time."

Optimus agreed.

"Then we remain concealed."

Tarn's tone hardened. "And observant."

"Careful," Sideways added. "You almost sounded curious."

"I did not."

That earned a low chuckle from Sideways.

For now, they knew only what the old mechanic had told them long ago:

His land would eventually pass to his niece.

The uncle was gone.

His niece had arrived.

And none of them were ready to let her know what she had actually inherited.
