It's an even trade for everything Stratos Caelus knows about Nekomata and demons in general that she'd rather no human know. The true nature of a demonic contract places much more power in the hands of humanity than they realize, despite the very real dangers in making one. Ownership of a soul is serious business and for a mage who's by all accounts going to live much longer than the ordinary man it's a long sentence of servitude.

Still.

Neko doesn't regret her choice. If she had to be lashed to anyone in this multiverse, Stratos Caelus is probably her best option.

"I thought you took leave for that. Am I covering for you for unfinished business here, or are you really expecting me to pretend to be you around your family?"
