I'm not sure how hard it would break the canon seeing that it's already been established that Miyu can shop and send packages across all factional borders. She bought the Imperator a human foot massager. She sent Eos a homemade angel sweater. Apparently the one thing Miyu is good at is dancing back and forth across factional lines. She somehow sent stuff to the demons who all want her dead for her betrayal!

I feel like this is a very subjective case. IIRC, Miyu used some kind of messenger to send those gifts as opposed to sending them herself. There's a difference between sending someone to the three Factions and crossing Factions herself.
