Alright, so some context first.

Before the scene, there's this battle between these three Seraphs from an alternate world, Eden, Zion, and Gnosis, and these three Succubi from another world, Lilith, Morrigan, and Astaroth. Sonya, who's been apprehensive leading up to this moment, steps forward and demands that they stop fighting, before she becomes an Apoptosis. This is Sonya Chaos, in her attempt to prevent them from fighting.

And so, you fight Sonya since when she became Sonya Chaos, she summoned forth Andramalech into this world, which was destroying it. After beating her, she sorta comes back to her senses and sacrifices herself to destroy Andramalech, but not before rewinding time back to before there was any conflict at all and replacing herself with another, "Normal" Sonya. Though she now has the Lowly Apoptosis class unlocked.

Also, you learn that killing Ilias was what screwed reality over in the first place, because if she's dead she can't destroy Remina, and because of that an experiment was performed which started the whole Chaosization problem which has been destroying worlds.

And no, the last part is actually still in development, though they're doing this little post game crossover thing right now.
