Honkai Impact 3rd - Everlasting Flames

When the darkness seized the long night Did it envisage its end at the hands of a shooting star?

She is Kiana Kaslana, K423, Sirin, Herrscher of the Void, and Herrscher of Flamescion.

She broke away from her former self and past confusion. She will go toward a brighter tomorrow with an unwavering heart. She grasps her greatsword tight to protect all that is beautiful and give this sad story a happy ending.
