*~read at your own risk~*
from what I can remember from the novel, Luz (or Roux or whatever) was fighting so hard from the pull, Sera decided that she would release Luz in order for Luz to return to his "rightful owner" (it's a sad story really, cried so hard reading the novel) she said thankful and apologetic things to Luz whilst crying. Fortunately, Luz didn't want to leave Sera and just wanted to stay by her side, Luz was able to turn away from the pull.
BTW I mentioned that Maribelle is crazier than I thought she would because Maribelle is also a reincarnator.. (if that's a word but you get what it meant.) because she knew about the game and that she prolly had an 8th grade syndrome. It's ridiculous. Speaking of reincarnators, so far there were 3 of them, and that's for another story. ;3
I re-read the whole manga again since I forgot what he looks like. But it's def not the prince who has the sacred beast (phoenix). it's this one: https://www.mangago.zone/read-manga/holy_guardian_tiger/nbt/mpn_chapter-2128986/pg-22/
oh, another spoiler: (you're in for another treat. (。・ω・。)) This same person captured a sacred beast too, the sacred beast of the north. (o′┏▽┓`o)

When I read the next part from the novel, I cried so hard. இ௰இ and.. Maribelle is crazier than I thought being the "protagonist" of that game or whatever.
