Danmachi Valkyrie Oratoria

Sigrid Kaslana is a bundle of energy and cheerfulness, with a dreamer's heart. As the daughter of Alfia, a member of the Hera Familia, and Kevin from the Zeus Familia, she is destined for greatness. Unfortunately, after a devastating battle against the one-eyed black dragon, most members of the familia, including her father, were killed, leading to the remaining members being banished from Orario.

Alfia farewell to her daughter, handing her over to her younger sister, Meteria. Despite being abandoned by her own mother, Sigrid knows that she had a valid reason for leaving her.

After being left in the care of Alfia younger sister Meteria, Sigrid eventually lost her too, as Meteria passed away after giving birth to her son, Bell Cranel a few weeks later. This left both Bell and Sigrid in the care of their grandfather, Zeus, who adopted them as his grandchildren. Although Sigrid was saddened by the losses in her life, she never let it dampen her spirited nature.

Inspired by her parents' legacies and her dreams of heroism, Sigrid decided to leave home and head to Orario when Bell was about one year old. She knew that in order to become the heroine of justice she always dreamed of being, she would need to hone her skills and strength as an adventurer. With the goal of protecting her baby brother, Bell, and the future familia she would meet, Sigrid was determined to become a strong adventurer. Despite the hardships and challenges she may face along the way, her sense of justice and unwavering determination would guide her on her path towards her ideal.
