The Demon Prince of Momochi House by Aya Shouoto

On her sixteenth birthday, orphan Himari Momochi inherits an ancestral house she knew nothing about.  When she finally reaches the estate hidden in the woods she discovers three boys squatting in the house.  Turns out the house is the barrier between the human and the spiritual worlds and one of the squatters - Aoi - is the guardian protecting the humans and spirits from each other.


So far there are two volumes in The Demon Prince of Momochi House series.  The premise of the manga is interesting and the art is well done.  A great series for teens.
