Ralsei was made by Kris AND Susie!!

I know that Ralsei object theories are getting old, but I’m still invested in them. Can anybody hear me out on Ralsei being Susie‘s and Kris‘ bond/friendship in the light world?! ”But Kris and Susie were enemies in chapter 1!!“, sure, but even before they first entered the dark world they interacted neutral AT TIMES, wich showed the start of their friendship. It would explain why Ralsei was able to exist in every dark world‘s adventure. I know that it‘s unlikely, but to me it‘s such a sweet thought ☹️❤️
