This series is an extremely visually-intensive show that focuses itself primarily on the deep characters it uses to convey its plot. The plot itself is engaging right from the start, and in my case it pulled me from a sort of initial derision to instant engagement when they introduced time travel, which I usually find a difficult subject for anime writers. The feeling of full immersion never left me the entire time, and I adore the way they represented their magic in the everyday world. Honestly, lesser artwork would have outright killed this show, because the less sensical parts of the world seem less prominent when you're being bombarded by pretty colors.
That said I didn't give the show a 10, for the following reasons. The plotline has a solid baseline of awesomeness but doesn't do much to capitalize on that except display typical high school shenanigans. The author has a lot of room to work with within the constructed world they've made and really doesn't use it. Also, while the show rides on some pretty deep characters, some of the characters are lacking in depth by comparison, and a lot of the interaction seems very stiff. But all in all it's still above average in all qualities, with absolutely stunning art and sound.
I recommend this anime for anyone who likes really pretty stuff, or who likes Slice of Life anime with supernatural twists. It gave me a really similar feel to Violet Evergarden.
