天國の子午線：ヴァルハラ

Set a Fire in Your Heart
Welcome to Valhalla, the prologue short story of "The Meridian under the Heaven" series, the origin story of the Black Raven.
The story unfolding in Norway in the 2040s centers around the daughters of a Norwegian entrepreneur who founded a cutting-edge biotech company "Ravenscorp."
The narrative begins with the eldest daughter of Ravenscorp's founder and his first wife from a Japanese consortium, "Hikari Sunnvei," transferring to Norway. She dreams of reuniting with her half-sister, "Nøva Sunnvei," from whom she has been separated for ten years, yearning for a life filled with familial warmth and happiness. However, unbeknownst to her, she becomes entangled in a sinister conspiracy involving family secrets and a struggle for inheritance, which utterly upends her world.
Years after the conspiracy, in a future world dominated by capitalistic forces over governments, the Black Raven, a mysterious entrepreneur who is controlling a great power, rose to prominence.
