A light novel series written by Tachibana Koushi and illustrated by [[Tsunako]].

In the future, spherical so-called "space quakes" have destroyed a great part of Earth's landmass. In response militaries and scientific communities all over the world have worked together to find out the origin of the occurrences, to little effect.

Enter [[Itsuka Shidou]], a young man of above average skill in school but no experience with girls. By accident he stays near the area that was just ravaged by a space quake, only to find [[yatogami_tooka|a girl in a warrior dress]] who threatens to kill him. Before he can say much, she disappears. Afterward he learns that she, among others, is a spirit. Spirits come from another world and cause destruction whenever they enter the human world. Shidou is now given a choice to see how the military kills spirits, or take another option: date the spirits, make them fall in love with and surrender their powers to him so they can live among humans without fear of being hunted.

A very dating sim-like adventure begins for Shidou.
