More than twenty years ago, an evil summoner committed "Great Summon." One third of human beings were killed, and devils and monsters invaded the earth. One day, a painter Tamura Fukutaro moves in an apartment house called "Ashiaraiyashiki" and gets involved in the troubles of his non-human neighbors. It's the beginning of a severe battle among gods, devils and the ruler "The Central."

17 years ago, the "Conjurer of Calamity" bridged the gap between the human realm and the demon realms. Now, the world teems with other-worldly creatures and demons ranging from zombies to vampires to half-lizard men. Now after 17 years, these creatures coexist with the humans peacefully. In the mixed creature school of "Banmaden," three students live their daily lives finding the oddities of their world. The "fox demon" Hisagi Hatsune, the "raccoon demon" Futatsuiwa Mami, and the "demon dog" Kousenji Hoyu search their school and town for mysterious urban legends to solve. (Source: Mangahelpers)

From http://natalie.mu/comic/news/89562 (replacing this with better translations or summaries encouraged): In the same world as [Ashiaraiyashiki no Juunintachi](https://www.mangaupdates.com/series.html?id=4719), two women move to a large trailer and fight off monsters that appear along their way.

Kuroro is thrown into another world with nothing, but it seems there are "haunted properties" here too. So he decides to live in a "haunted property" in the other world too.
