humans are enslaving everyone that ain't human. Killing, raping, torture crap is common. The miko thing is being used by the church/kingdom as a way to justify the horrible crap they are doing. Of course the humans realize her sister ain't the miko so they start hunting for her which leads to further tragedies and sad events in her life. And its all freaking weird when the author keeps dumping cute crap in between the horrible scenes as if the author is apologizing to the readers. Like, "Here is some fan service of cute stuff before I write more horrible crap."
