This is definitely one of my top 3 favorite anime ever. The art style is beautiful, and the story is very touching. The show makes me feel every emotion no matter how many times I watch it. Being only a 26 episode series, it's super easy to watch/re-watch in a couple of days. The soundtrack definitely plays a big part in this anime being awesome. Totally recommend it for anyone over the age of 12-13. It is quite violent and bloody, however I enjoy anime that are gory. So if you're okay with goriness, I totally recommend this anime!
