>It's why she's the only final boss Kirin didn't get to have a fight against.

It's because she's too strong. In a world where she won, she's a virtual goddess. Besides that, what would be the point of contention with Zonda? The fight with Nova happened because GV and Nova are angry idiots around each other (it was GV who actually initiated the fight). Asimov attacked them because he's insane. What would cause Kirin to fight Zonda?
