Hey there, first post here (though i've been looking around for a pretty long time), not sure if i'm supposed to introduce myself somewhere or something...
Anyway!
I've replayed CP's story mode recently, and I noticed something pretty interesting at the end of chapter...13 i think it was? Anyway the one where after Azrael gets defeated, we see Hazama talking to the Imperator.
At a certain point in this dialogue, Hazama asks why is she always so rude to him, and she answers that "Her behaviour towards him should be expected, since he already broke her vessel once in the past"(or something along those lines).
So i've been wondering, do we know what she's talking about, or is it still a secret to everybody?
