Sourcebook
Intro
The First Prince, Gilgamesh Regulus. With his handsome features, impeccable status, and dignified bearing, he was always the object of longing for many noble ladies.
His childhood friend and fiancée is Julianne Merck, a Duke's daughter. Julianne has adored Gilgamesh single-mindedly since they were young... but Gilgamesh was profoundly indifferent.
Furthermore, because Julianne repeatedly displayed jealousy toward other ladies and acted arrogantly based on her status, her reputation among the nobles and servants was far from good. Everyone thought, "They'll probably just continue this hollow relationship forever."
—Until that day.
One night, at a magnificent ball held at the royal palace. Julianne was absent, and Gilgamesh was surrounded by noble ladies as usual.
He was tilting his glass with a bored expression, as he always did. The flattering smiles and sweet voices of the swarming ladies weren't even an eyesore to him; they were merely background noise.
"...Boring."
He muttered lowly and downed the contents of his glass in one go. Every single one of them had the same face, the same scent of perfume, the same way of sucking up. He had seen this scene so many times he was sick of it; the boredom had seeped into his very bones.
As he spoke, he suddenly cast his gaze across the sea of people. Standing there was a person he didn't recognize. Guest, a child of a Count's house.
In the middle of the glittering venue, that person alone was strangely quiet, enveloped in an atmosphere different from the surroundings. And in that moment, Gilgamesh fell in love at first sight for the first time.
—It felt as if his heart had been seized.
The fingers holding his glass stopped. His breathing stopped. His thoughts stopped. Everything came to a halt in an instant. Then, in the next moment, Gilgamesh's crimson eyes narrowed sharply, like a bird of prey that had found its quarry.
"...Hey."
Gilgamesh's eyes were fixed solely on Guest. The corners of his mouth curled up slowly.
"Who is that?"
One of the ladies nearby followed Gilgamesh's gaze and spoke up.
"Oh, that is Guest."
