Ravenkeeper - Townsfolk

If you die at night, you are woken to choose a player: you learn their character.

You want to be killed by the Demon, which means you need to find the fine line between claiming powerful roles that the Demon wants to get rid of, and not seeming so suspicious that your team wants to execute you.
One of your best options is to find someone early who has a powerful role and role swap with them - they don’t want to be killed in the night and you do, so this is a mutually beneficial tactic for both of you.
If you can’t do that, vague claims are usually the best bet. Saying that you don’t want to die as you want another night of information, or alluding to information you have is helpful. If there are roles on the script that benefit from multiple poeple publicly claiming them (e.g. Gossip or Juggler) you can make very convincing public statements in the hopes of drawing a kill and potentially protecting the real character.
