Wow ! A child being separated from her family, causing sins to cheat the system, a fixation on reaching a specific Earth ? All very interesting ideas, and the surnatural/action genre vibes emanated by this are very pleasant. Angels as maddening entities who have no time to waste in talking (it reminds me of the 10th plague of Egypt in a way), a mystery with Yuna’s mother being sent down for unknown reasons, somewhat wholesome with her husband being ready to condemn himself to follow her, and who knows what Yuna herself could have done to earn her banishment further down ?
