You Were Supposed to Run a Repair Shop—Why Did You Start a Mecha War?

“Kiddo! Mom and Dad are leaving. Don’t miss us!”

The young man stood in his home, staring at the letter in his hand, completely frozen.

“Kiddo! We’re not that heartless—we left you a mecha repair shop. Work hard~”

Young Man: ……

“You call that dump a repair shop??”

Just then, a system awakened. The rundown warehouse in front of him transformed into the strongest mecha repair shop on the planet.

“Boss… isn’t your repair fee a bit much? It’s just a Ground-Class Mecha and you’re charging 1.5 million? Rip-off!”

The young girl looked at her beloved mecha and the sky-high repair cost, torn with indecision.

Young Shop Owner: “I don’t just repair—I can awaken your mecha’s innate abilities!”

“Could you really bear to let your mecha become a pile of scrap?”

“Are you insane?! I just came in for a tune-up and you want to charge me ten billion?!”

“This tune-up could launch you to the top of the interstellar ranks. Are you sure you don’t want to reconsider? Of course, you can also go for customization—innate skills, rare armor, truth-grade materials—I’ve got everything you need. Satisfaction guaranteed!”

…

When alien invaders attack and the tide of star beasts surges, truth-grade mechas rise across the Blue Star Alliance.

The young man charges ahead, sweeping through enemies like a storm.

Everyone: “You were just supposed to run a repair shop, and now you’ve triggered a mecha war?!”
