Hayate Higurashi was seen by people as a modest person. He was smart, talented, kind-hearted, and most of all someone you could rely on. However, what most people didn't know was that he was a half-demon of the Inu yōkai, or dog demon clan. He became childhood friends with the Okumura brothers Rin and Yukio, as they were also like family to him. Just like Yukio, he was also trained by Shiro Fujimoto and his family in the ways of becoming an exorcist. He learned to control his powers and wield a copy of his father's sword, Tessaiga. Before Leaving for True Cross Academy with Yukio, Shiro asked Hayato for a favor. He explained about Rin and how his powers would one day manifest, and demons would be after him, he asked Hayato if he could look after both Rin and Yukio and help them out from time if something were to happen to him. He agreed to look after and protect them both. All rights belong to Kazue Kato the creator of Blue Exorcist and all images and pictures used in this book belong to their respectful artist)
