Kallen Kaslana

The most famous Valkyrie warrior who has ever lived, and the ancestor of Kiana Kaslana, Kallen is an elegant Schicksal knight whose spirit lives on to fight the Honkai. She remains the object of the Overseer Otto's eye.

She was the most powerful among her fellow valkyries in her era and was Otto Apocalypse's first love interest but she did not return his feelings.

Kallen wielded the Oath of Judah until her untimely death in the hands of a Honkai beast.
