Eldest Hīragi Son

The eldest Hīragi son is a historical figure in Seraph of the End who helped perpetuate a family house system that was detrimental to others, that has lasted to the present day. Mentioned in the Seraph of the End: Guren Ichinose: Catastrophe at Sixteen manga, his actions are recounted, and his harmful legacy endures.

Appearance
He is visualized with long hair, and resembling his brother.

Personality
To win the favor of a girl he liked, the eldest son felt fighting with his brother using a sword was the way to go. Seeing that he was not successful, force was used to exert control over others. Assaulting the woman who he supposedly loved, he also mutilated his brother, before banishing them from his own Hiragi house, and the Ichinose house. His extreme cruelty was not used to destroy the fledgling Order of the Imperial Moon they established, but only since in his sadistic view it was his son when born from the woman who would become its head, in an act meant to shame them.

History
500 years ago he was the eldest son of the Hiragi family, already the strongest house of the great families. When a beautiful girl was born into the Ichinose family, he fought his younger brother over her. Over events, he found that the girl had feelings for the second son where he observed them together. One night, seizing her by the arm, the eldest son forcibly raped the girl to impregnate her with his child. With his brother’s arms bound, the eldest son castrated him before throwing them both out of the family.

When his brother and the girl he liked formed a new religious organization called the “Order of the Imperial Moon” it is stated the eldest son had the capability to crush the organization with the Order of the Imperial Demons at his disposal, yet did not do that. Some present day views from students under the Hiragi family’s influence feel this was because the eldest son was forgiving, where others assume he done it to humiliate the second son and the woman.

Story
His actions are recounted by a group of students who were discussing Guren Ichinose and his family house. With the Hīragi family's treatment of others, including the Ichinose house, which has lasted until the present time with Tenri Hīragi and Kureto, he had established a ruinous precedent that endured for centuries. The system would be what Guren would act to destroy.
