Seishirō Hīragi (柊 征志郎, Hīragi Seishirō) is a minor character of Seraph of the End: Vampire Reign. He is a person of influence as a Major General of the Japanese Imperial Demon Army and a member of the Hīragi Family.

He appears in the Seraph of the End: Guren Ichinose: Catastrophe at Sixteen light novel series.


Seraph of the End - Seishirō Hīragi (Anime)

He has black and dark grey hair styled in a Mohawk, and thick, short eyebrows, and narrow red eyes.

He wears the standard JIDA uniform which consists of a long-sleeved black coat with red details including the shoulder epaulettes which has a brown Sam Browne belt passing diagonally over his right shoulder and two rows of gold buttons on the front which are unbuttoned at the top. Along with that, he wears an armband on his left arm and a black belt inside a white band with red trims. He also wears the uniform trousers with two white belts around his left leg, and black shoes.


Seishirō is rude and has an offensive attitude towards the lower branch families, as shown by his treatment towards Guren disrespectfully.

He acts very proud, but he uses his father's power and name for protection. Although he feels angry when his father is insulted, he begged for his life when Kureto threatened him.

Kureto calls him an incompetent coward and states that Seishirō has never stood on the front lines.

He has a inferiority complex about Kureto and secretly plans to outwit him someday.


Raised by the Hiragi family, he has always been inferior to Mahiru and Kureto. Even Shinya out-classes him.

Story: Vampire Reign

Second Shibuya High School Arc

He first appears in chapter 5 during a meeting among the top-ranked members of the Japanese Imperial Demon Army. Guren wonders why a member of the Ichihnose family which is just a branch family is even attending the meeting and Seishirō agrees. He then calls Guren a loser, telling him to leave already.

Nagoya Arc

Seishirō reappears in chapter 32. On his father's orders, he arrives with some soldiers in order to assist Kureto. He informs Kureto that their father will not tolerate failure, but Kureto laughs and tells him their father can be angry in Hell. The two argue, and Kureto intimidates Seishirō. When Seishirō calls for backup from his soldiers, he sees that Aoi and another soldier already took them down. Aoi informs him that preparations are complete.

When Seishirō hears that Kureto is getting on a helicopter, he asks where Kureto is going and says the vampires are headed to Shinjuku to attack them. Kureto states he will imprison the vampires in Nagoya. Seishirō says he will report Kureto for defying their father, so Kureto draws his sword. Seishiro panics and begs for his life. Kureto says that Seishirō's obedience to those in power is useful, so he tells him to wait in the brig until he returns with "supreme power." Kureto does not explain his plans to Seishirō.

Powers and Abilities

Natural Abilities

In the Light Novels, Seishirō is shown to be stronger than most students, as expected of someone with the Hīragi name. He easily defeated Sayuri in an one on one fight, and proceeded to strip her in front of the cheering audiences. However, he did not dare to fight Mahiru, recognizing his sister as an opponent he could not even defeat.

He is very strong in both physical strength and magic, but he is shown to be a cowardly fighter, and leaves all the fighting to his aids. Despite being a strong fighter, he's unable to best Guren in a fight.
