KAMUI (カムイ) is a Japanese shōjo manga series by Japanese author Shingo Nanami. The manga was serialized in the Monthly Stencil magazine, and later serialized in Monthly Gangan WING magazine, and published in Japan by SQUARE ENIX.
In post-apocalyptic Japan, a devastating earthquake called the "Great Sinker" sank 1/3 of the southern islands and cities were destroyed.

Fearing that the imbalance of the spirits known as the kamui will destroy the Earth, a teenager named Atsuma is sent from his village to retrieve Okikurumi, the sacred kamui, to restore the balance and peace.
