Actually, I can't use any Personas while I'm using the Universe Arcana, I think. I can use multiple Personas because I'm a Wild Card, which is just the term for someone who can.

Souzen... He has an old enemy, who's a Fool and Wild Card like me. That's who he hates. I referred to myself as a Fool in front of him once and he immediately began associating me with that enemy.

Now, though, I think he hates me for the same reason I don't hate him. I mentioned he's a lot like who I used to be - his life completely empty. He...might see that, too, and hate me for finding a way to fill my life when he couldn't.
