How about Kasi as the Moon and/or Wander as the Hierophant?
[THE MOON] - If they had to choose one trait to describe themselves, what would it be? Is it a genuine answer, or the illusion/persona they put on for others?
Kasi would describe himself (accurately) as resilient; being the chosen of a god puts a LOT of pressure on a guy and he's stood up to it admirably. But by the time the story starts for him, he's already starting to be kinda done with the expectations that puts on his shoulders...
[THE HIEROPHANT] - What are important traditions to them, if any? Do they stay true to these traditions, or do they adapt them to fit their current situation?
A personal tradition more than anything formalized, but Wander reads his own tarot daily to determine what kind of magic and spellcraft he'll need to prepare for the day. The intent behind this is to take the stress of choice (and choosing wrong) out of his hands by letting fate take the wheel. Unfortunately, this gives him a completely different kind of stress sometimes.
