i am a big believer in letting music (and other media) come to you when you're ready for it. you may only know vaguely of an acclaimed beloved artist and suspect that you'd be into them but just... not ever get around to it. and then in 15 years one of their songs just hits you the right way and what a gift to suddenly have all of their works to explore! there is no hurry; what is good is always good.
I really like this anime!!
I can already feel it in my bones that it's not gonna get popular since it's only available on Hulu/Disney >>
BUT
I def recommend it, very interesting story and I picked up the manga and it GOES PLACES
Also, if nothing else check out the opening as it's a real banger~
