A-kun_Kaslana
Sigrid Kaslana was the greatest swordswoman of her world-a cheerful glutton, an incorrigibly reckless hero, and the beloved captain of the Astraea Familia.
Then she was beheaded by the stolen corpse of her own mother.
Instead of returning to the gods, Sigrid's soul crosses the boundary between worlds and merges with the newly forming soul of an unborn child. Reborn as the daughter of a noble family, she retains her memories, peerless combat talent, and an unusual soul containing two spiritual cores.
The Voice of the World grants her the Unique Skill 『Heroic Aspirant』, but Sigrid has little interest in political marriages, noble obligations or spending her life inside a gilded cage. At eight years old, she runs away in search of the freedom to choose her own path.
One month later, she meets Shizue Izawa.
Under the wandering hero's guidance, Sigrid begins a new journey-one that will bring her into the lives of Hinata Sakaguchi, Yuuki Kagurazaka, Ramiris and, eventually, a peculiar slime named Rimuru Tempest.
But the Central World is governed by souls, Skills and evolution. Within Sigrid sleeps an impossibility the world has never encountered.
Twenty years before Rimuru's arrival, another extraordinary soul has already begun changing the course of history.
This is the story of a girl given a second life-not to become a hero again, but to discover whether she can live for herself.
