not to seem like im beating a dead horse, but while Phos is a sympathetic character, and what they've undergone is definitely more than anything should have to experience, by this point they've definitely lost sight of their initial reason for going to the moon. The gems who've been crushed will never reassemble, and attempting to do so will cause the Admirabilis to go extinct. Furthermore, as readers we know that if Adamant prays all life will disappear! Phos isn't a tragic hero because they're misunderstood, they're a tragic hero because what they wanted was never attainable in the first place, and in trying to attain their initial, impossible goal (the resurrection of the crushed gems), they've sacrificed everything that they once held dear
phos is a compelling protagonist bc they're relatable and wrong and framing the primary conflict as being between a misunderstood visionary and a backwards society that needs to be forcefully dragged into the future is a waste of the like 11 chapters ichikawa spent crushing phos's spirit
