Inukami! revolves around Keita Kawahira, a descendant of a Inukami-tamer clan and considered a failure by the clan due to his attitude towards his duty. Inukami, literally "dog god", are benevolent creatures that possess spiritual powers. They are a type of demon with the appearance of a dog who can transform into human form. Along with a partner from the historic Inukami-tamer clan, they act to obliterate evil and proliferate righteousness. Keita is initially unable to find an Inukami to bond with, but eventually a beautiful Inukami named Yoko decides to become his Inukami, causing Keita to become overjoyed. However, his joy is short-lived when he discovers that she is a very problematic and uncontrollable Inukami. From then on, Keita's life becomes filled with never-ending embarrassment.
