Is bloodline crusher constantly active Ronnel?
Yes. It doesn't affect sight based bloodlines unless they see his tattoos, or touch based ones unless he touches them intending to deactivate their bloodline / they see his tattoos.
He wears his trench coat sealed up all of the time, so the only person who even knows he has the Bloodline Crusher is Aki, who saw the tattoos while they were training.
But, to look at him with your Ranmaru, you would see the tattoos, and thus it would be deactivated.

Seriously, the Castelo is PART of Grass. So that list can't be accurate.
