Shinya is the Major General of the Japanese Imperial Demon Army. He is shown to be a very calm and somewhat gentle person. He has been friends with Guren since their school days and cares about him, even though he seems to enjoy picking on him, often by forcing Guren into awkward situations or simply annoying him.

He is highly skilled in long combat battle and fights with his Demon Gun "Byakkomaru," which can spot his enemy perfectly and shoot when Shinya says "Bang". Byakkomaru's bullet holds the image of a "White Tiger." He has high capacity of spellcraft from since childhood, Shinya is not comfortable about being with the Hiiragi's.

[Spoiler: He is a adoptive son of the Hiragi Family and was chosen to marry Shinoa's older sister Mahiru.]

[Spoiler: In the second season of the series, he decides to join the battle with the "Noble Extermination" team in order to support Guren.]
