"Alien" means "someone from outside". It has settled into the imaginary collective as "extraterrestrial lifeform" due to the movies, but strictly speaking, one can be an alien just by going to the neighboring town. I gather that by 【異邦人】 they mean "people from other worlds", much like Rou's soul, but in physical body, so maybe "Otherworlder" would fit the bill.
