I don't have a waifu, but I would choose a normal woman from some world I wanted to visit, the plan would be simple to bring something of universal value between her world and mine, like Gold or something that is valuable to her, I propose a marriage agreement that is annulled as soon as we are back in her world, she continues her happy life and I go on an adventure.

Now the question would be, what world should I visit where I won't be killed in seconds?
