The Zashiki Warashi of Intellectual Village

The Zashiki Warashi of Intellectual Village summary:

Intellectual Villages are old fashioned rural villages recreated with cutting edge technology. Those villages attract the j.a.panese monsters known as Youkai.
The high school boy Jinnai Shin.o.bu lives in one of those villages and has a Zashiki Warashi living in his house. He tends to run across Youkai with unnerving frequency and this often leads to trouble for him.
