In the “Great Disaster,” Japan has been thrown into chaos by onmyouji (a kind of magician).
Harutora Tsuchimikado was born into an onmyouji family, but has no power whatsoever. His childhood friend Natsume (another member of the Tsuchimikado family) appears to him one day to take him up the promise he made long ago to become her shikigami (familiar). A battle between onmyouji is about to begin.
Tsuchimikado Harutora was born into the prestigious Onmyoji family, but can’t see “spirit energy”. Therefore, he’s been enjoying a peaceful daily life with his friends at the Onmyo branch school. One day, his childhood friend Tsuchimikado Natsume, heir to the head family, suddenly appears. Will this cause his destiny to spring into motion?!
As a descendant of the famous Tsuchimikado shaman clan, Harutora is a failure; he has no talent, can’t grasp magical theory, and can’t even see spirits! Thankfully, his cousin Natsume is the heir to the family line instead, but unfortunately for the girl, it puts her in the crosshairs of other shamans who hold grudges against their clan or seek to exploit her power for their own. To help keep her safe from the dangerous world of the supernatural, Harutora decides to become Natsume’s familiar and protector. So together, they learn about magical techniques, banishing spirits, and fighting together as a team – while doing their best to keep Natsume out of harm’s way.
