Liliya Olenyeva

8
Liliya Olenyeva is the younger twin of Rozaliya Olenyeva, who grew up in the same orphanage as Bronya Zaychik and Seele Vollerei.
While growing up, Liliya Olenyeva was always under her sisters protection. Due to an accident, her body was modified, causing her to rely on prosthetics to fight. A prominent side effect of the modification is that she experiences extreme sleepiness at exactly 7 PM (19:00) every day. The exact reason for this is unknown.
Currently, she, alongside her elder sister Rozaliya Olenyeva, are training to become Valkyries under Theresa Apocalypse's teaching and idols under Shigure Kira's guidance.
She is the calmer of the Olenyeva twins and often takes the role of a straight man in their comedic duets. Similarly to Bronya, she would often call out her sister as "Rozaliya Idiotka", not unlike how Bronya also calls Kiana.
