A diligent second-year student from Shinjuku Academy who is also the representative of his class. He can be a bit stubborn but he has a wide range of knowledge and is highly intelligent. He loves the occult and is also a childhood friend of Kengo Takabushi. He's an avid reader but does not actually get along with people who rely on book-smarts.
A second year student of Shinjuku High School and childhood friend of Kengo. At times he can be strict and inflexible, but he's very intelligent and absorbs information easily. The one red mark on what is otherwise the model honor student is his fascination with the occult.
"This is the form Shiro takes after unleashing the power of his Book, one of only five Books of Madness in existence. Unleashed along with it is the Rule of Resurrection, which draws the ruler of deep space, and entity best left alone. The price for this transgression is a loss of sanity."
His sacred treasure is one of only five of its kind in the world, a magical tome said to drive men to madness, but Shirou's uncontrollable drive to learn more tugs at his mind, inviting the attention of dangerous forces humans weren't meant to meddle with.
"One day, he opened his magical tome and saw instructions for an offering his loyal Devil familiars would enjoy. The obscure ingredients the recipe required, the previously unheard of cooking method, and the mysterious scent wafting from the boiling pot all made his heart race. Though he was nervous as to what blasphemous concoction might be wrought, all that was produced were some ordinary pieces of chocolate. The Devils happily devour them one after another and his patissier skills continue to improve spectacularly. Nowadays, he's the talk of the school and ceaselessly sought out by those who desire chocolate, as well as those who seek his tutoring."
