Give me an order to watch these in
Angel Beats, Rune Soldier or Elfen Lied
You should totally just skip Elfin Lied.
You've never heard of Elfen Lied?
But yeah, start with Angel Beats.
Yeah most anime fans I know have at least heard of it if not seen it.
I'd also recommend starting with Angel Beats.
And after you're done with Angel Beats, you might want to watch something that isn't depressing as all fuck.
