Our main characters are three teenage girls that belong to a police force which uses futuristic technology. The three of them have mechanized body parts, and thanks to instantaneous "recalling" tech, they can be provided with strong body armor powering their up their roles as a strong close-quarters brawler, a deadly sniper and a lackadaisy steel-wire user respectively.
In this book, they each get involved in cases which reveal how they got into the police force and what they fight for. The hot-blooded brawler's story was passionate and straightforward enough, the detached and manipulative sniper's story was so dull I had to force myself to read it to the end, and by the time the quirky steel-wire user started, I didn't see any improvement so I just had to drop it.
Also, I don't usually bring up writing style, but the author employs unusual symbols as shorthand, like literally writing "Suzutsuki + Kagero — clapping" or "Yugiri = impressed", or using "/" (slash) when describing different parts of a person's look or different beats in an action scene. I honestly can't come up with any reason why a writer would use *less* words to weave a story, yet I can easily think up adjectives to describe the resulting effect, such as "boring", "uninspired" or "lazy".
