True, but for the hypothetical back and forth I like the idea of him opening the door to a 7 foot tall nen-raven that bellows loudly at him in a godzilla like fashion before attacking him ( which would likely be the same happenstance if he came through the window) while she keeps sleeping. More likely she'd sleep with her full unkindness out in the room as they are easy to maintain indefinitely even in sleep and can be given long term orders like noisily engage anyone that comes into my room as to wake her up and she can properly go into the fray

But some sort of fight ( one not safely planed or confined to the sparing room ) between Ivy and mars should happen, it makes sense and would be fun. If the GM was okay for such an event of course.
