The cynical side of me is assuming this has nothing to do with Xeno series at all, as this game was previously called Monado which basically looked like Soma Bringer, or frankly, the pale imitation of FFXII. I guess this game got the prefix of Xeno simply for a promotional reason, and if any, there will only few connections, but it's just my guess. I'm curious who's the composer. The piano track is not personalized enough to verify the style. Soma Bringer was copyrighted by Procyon Studio so Mitsuda and co.'s involvements were anticipated at an earlier stage. One of the Monado trailers sounded like Shimomura.
I confess; why I'm posting here is this game used to be seen as Matsuno's next project
