Well because I voted for them, 1 - one is the princess of the Elves Riveria, being she very talented and being able to accompany him on his journey (not being a burden) in addition to being good with children, we can see that because she created Aiz ! 2 - Ryuu she is a very talented elf and would not be a weight in the MC's journey besides being able to help him a lot and having similar ages.... 3 - Freya although she is a Yandere, she would just like to be really loved in my view, we can see this when she offers for Ryuu and her to share the Bell, moreover because he is a reincarnated soul from another dimension, although his memories are hidden, he would still draw her attention in my view
