Kallen Kaslana

6
Kallen Kaslana was the most famous Valkyrie warrior who has ever lived. She became the captain of Schicksal's Valkyries in 1469 when she was only 16 years old after passing the trials and was Otto Apocalypse's only friend.
Born into the Kaslana family to Francis Kaslana, Kallen was the youngest of six children. In 1465, a twelve-year old Kallen meets a thirteen year old Otto, who's flying contraption she had witnessed, and the two became friends. A year later, however, her father perishes, defending her and Otto from Honkai Beasts when they were eavesdropping on his mission. Three years later, Kallen would have passed the trials and become captain of Schicksal's Valkyries, where she will spend the next eight years of her life sealing more than 1,000 Honkai Beasts, as well as wielding the Oath of Judah. However, in 1475 at the Battle of Kipchak Steppe, Schicksal forces were forced to stop their conquest eastward by The Celestial, who wounded and defeated Kallen. This was the waking point for Kallen as The Celestial asked her if she knew what she was really protecting.
Due to her household, Kallen is a very devoted believer in justice and defending the innocent. After her own father's untimely death, she had fully committed to a life of endless fighting and risks for the sake of humanity. Despite these serious traits, Kallen is far from them, as she carries a breezy aura of kindness and almost childlike awe at the world. She also has a sweet tooth and a knack for flair and extravagance, as seen when she was immersed heavily with Shakespeare's dramatic plays and her taking the mantle of the Rogue Extraordinaire. Kallen does everything with an undying passion and determination, but also would often opt to see the good in people, no matter what.
