does that mean the 'old dude' is the Demon King/Lord? That would make A LOT of sense, and the other person mentioned Haru's friend being raped to death by Soldiers, and the only one with a connection to Soldiers (that I can think of) is the 3rd in rank, the beautiful singing onee-san.

I'm too impatient to wait for the manga, guess I'll have to scavenge the interneet for novel spoilers.
