Alright, something more in depth now.

If Mastema injures Apeiros to the point that she could actually kill her (an uncertain possibly), then her Type 8 immortality wouldn't be worth much, given that Mastema can erase information and negate Type 8 immortality reliant on physical laws like entropy. Honestly, they have answers for most of each other's abilities. Quantum manipulation, spatial manipulation, death manipulation, conceptual manipulation... she can counter Apeiros removing her own concepts by just forcing her own on her.

Analyzing Mastema's information will not go well. Looking into her existence, magic, and history is basically equivalent to being hit by her magic. Except worse. It can easily erase people from existence or drive them insane. Mastema has experience with things like Superiority (Jophiel can do like the same thing), and they have a mutual understanding of higher dimensions, though the specifics are of course, debatable due to lacking context. She can deal with Boundless Dominance, given that black holes aren't all that special to her.

Of course, Apeiros has resistance to many of her abilities and can evolve to get better at this. Mastema will evolve in response and grow increasingly powerful as well. So inconclusive seems inevitable.
