Very good, indeed. The two main leads play off each other well and the action is well animated and inventive.

School girl assassins is nothing new, but is usually played a lot more on the tragic/somber side, so a slice of life light heartedness is a welcome departure for a show where people actually die. It reminds me a lot of Princess Principle, and that makes me very happy.

I especially appreciate that main girl has more personality than the naïve 'don't let anyone die' characters normally get. She is familiar with death and is confident in her ability to ward it off and complete her missions satisfactorily. She then shows off that her confidence is warranted in some earnest if not convincing gun-fu that mixes John Wick style competition shooting and reading recoil to dodge bullet trajectories, it looks like. I'm too old to buy into it, but the effort makes it fun to watch and hand wave.

The characters are more interesting, sly, and interwoven than you might think at first blush, and the pace is good. Don't sleep on this.
