What it says on the tin, an angsty lesbian slow burn enemies to lovers mech story. The addition of the titular gearbreakers is definitely a really cool twist, and shines at a couple of different points, though it has the side effect of turning some of the mech combat to human-scale combat with nameless "guards" set inside the mech.

Still, it has some excellent action sequences, and it was engaging enough that I stayed up late to keep reading more chapters.

I might recommend it if you're into mech yuri, but keep in mind that it's meant for teen audiences, with all the tropes and caveats that come with that, including so much angst. A side effect of this that I appreciated is that it's a romance story that doesn't use the language of sex to communicate beats in the relationship, which can sometimes be hard to find.
