Mecha Girl Era: Arc of Light

[No System] + [Mechanical Girl Derivative] + [Racing Competition] + [Goose-Style Recipe]

This is a world that worships speed and honor, but the beings speeding around the racetrack are another intelligent species: mechanical girls.

Five years ago, legendary driver Bai Ling died in an accident during a race. On the same day, the infamous Purple Moon Incident erupted in the High-Speed World, claiming fifty thousand lives. I was one of them.

My name is Bai Xuan, the “mad genius” of the tuning world. Whether your mechanical girl is on the verge of death or badly broken, you can leave her to me. I guarantee you'll be satisfied.

Of course, I'm also a racer. On the track, they call me “Light Arc.” I will lead my mechanical girls in uncovering the truth behind my father's death.

My name is Xingguang, a visitor from the stars, but I seem to have lost my memory... Still, it doesn't matter. I'll always stay by Danna's side. It's just that I can't explain this feeling. What is it?

He always seems to be so busy, and he often pushes himself too hard... I can't take it anymore. My feelings for Danna are getting stronger. What should I do?

This is the Do-Whatever-You-Want Tuning Shop. Our motto is: If you bring it in, we can tune it.

Mechanical girls modified with brute force? We can tune them!

Mechanical girls who've shut themselves away? We can tune them!

Mechanical girls from another world? We can tune them too!

But what the heck is a core weapon?
