I’ve been wanting to properly get into Seinen manga for a while now, but looking at the options is honestly a bit overwhelming and I’m not sure what I should actually go out and buy first.

I'm open to almost any genre (dark fantasy, sci-fi, slice of life, psychological thrillers, historical, etc.).

If you were introducing someone to Seinen for the first time, what’s the one series (or top few) you’d recommend picking up physically?
