Thought it would be cliche but turns out that this manga takes a creative take of the sci-fi tag; instead of robots you get animal-plant hybrids called daphne, I think. All daphnes also have a weak point called cloris, which if that part is saved the whole daphne can be saved. That's all they told at chapter one.
From the very first chapter there is already worldbuilding, character depth and character development. Definitely recommend it.
