What adult-fantasy comic book can you recommend...

...

I made one years ago. While it's a great series, it's neither a fantasy series, nore particularily erotic after you aren't a teenager any longer.

This one's about a dude who's sentence to death because he tried to break the fourth wall, user.
It's exotic rather than erotic.

bump

Love & Rockets
not very erotic on the whole, but it's got lots of tiddays and ass and some dicks, too

Monstress

Fatale by Brubaker?
It's not that old, but I think it fits.

It's a pretty C'thul story, bro.

Dorohedoro, it's Cred Forums but pretty damn good. I'd say it has a bit of a rocky start though.

I'm being facetious, it's a manga. But it well worth reading and arguably the high water mark for adult fantasy in comics

But...nipples.
