Could Charis be a descendant/relative (unsure of timeline) of Zephyr? They share a resemblance, and with that doubling hit count stuff that Zephyr has now, it seems kind of likely. Plus, Zephyr's lore seems to imply he was part of a family that was at least semi-important, and Charis was in an aristocratic family that held the Sacred Treasures. Going off of the Sacred Treasures thing, Zephyr's ES is Nameless Keeper, so maybe they're in the same family?

I'm probably looking into this too much.
