Pirate and Elven Blessing

If I get either of these characters to level 70 and "Link" one of the skills, do the original characters lose the skills when I do this or does it work like the Empress Blessing in that it's dependant on the character existing.

Also while we're on the topic what Blessing does the Demon Slayer get?

The actual Mercedes or Cannon dude do not loose the skill. You can only link the skill to another char once a day, and only one at a time. The link skill id dependant upon the original character so you can't delete the merc but keep the blessing on a main.
Demon slayers get + 10% damage against bosses.

You can only link the skill to another char once a day, and only one at a time.

Wait, so how does this actually work? Does the "link" only last for one day then it needs to be re-done? Or is it a kind of like...I select a character, it lasts forever, but it can be changed to another the next day if I want kind of thing?

This is correct.
