When Kazuya wakes up in the morning, in Naoya's apartment, he feels refreshed. It's the best rest he had for a while. Night in human world is much appreciated, as it is not as heavy as the demon realm's, and not as blinding as the eternal light in god's home turf. The cacophony of a regular human neighbourhood sounds soothing after endless days in constant war, after seemly endless violent songs of angels and victory cries of demons. And there was Naoya holding him as he slept, which was more than welcome. Family, at last. Demons were loyal allies, but this is his core family, his original family, the one constant family since Genesis time.
