* Based on the light novel series written by Tachibana Koushi and illustrated by Tsunako. Thirty years ago, the Eurasian continent was hit by a massive Spacequake due to Spirit activity, causing 150 million deaths. And now... Itsuka Shidou is living under one roof with two non-human Spirits — Yatogami Tooka and Yoshino — since dating them is the best way to avoid mass destruction occurring on Earth. And Shidou happens to be the only person able to seal the unfathomable powers of Spirits away.
