Sirin is the second Herrscher and the current era's Herrscher of the Void who fought over Kiana Kaslana for control over her body during her second awakening. Sirin absolutely hates humanity due to being experimented on by Schicksal, viewing them as nothing but insects that are beneath her and had tried to destroy them twice. Despite being once a kind and caring girl, Sirin had become obssessed power, genocide, revenge and supremacy of the Honkai, leading to her current personality.
