I'm just going to outright say it, I love this anime! The art style is beautiful, along with the animation, the locations are rarely ugly to look at. They really give the different characters good personalities and unique looks to differentiate between different characters. The OP and EP are really good and the background music also fits with the show's atmosphere. Overall, I really love this show and want to watch it to its entirety. But even though I love this anime, if you don't like literature or shows relating to historical events or characters, I wouldn't recommend this to you. About half of the showtakes place inside books already written and sometimes, you might need prior knowledge of the character's real-life counterparts to get what's happening. If you're willing to do that, I definitely recommend this to you, but if you're not, then I would say try something else.
