|Grave Mole, AOU
|Phase 1: For You, the Replaceable Ones
As "equipment" for the Geroy Level 4 Heavy Military Research Center, Lilja was spared the death sentence for a crime she committed (later revealed to be accidentally killing several instructors as a trainee). Her grades at the Suomenlinna Aerial Augmented Infantry School before her arrest were incredible, and her records at that school still haven't been broken.
Large changes have been noticed in her personality and character since her imprisonment, and some sort of experiment at the research center is rumored to be the cause.
Lilja appears as a young girl with long light brown hair and green eyes. Her mouth is distinctly "catlike". She typically wears a modified dirndl with a red ribbon and two hair accessories resembling cinnamon buns.
Lilja has some catlike qualities; her mouth occasionally takes on a catlike shape and she often ends sentences with "meow".
Phase 1: For You, the Replaceable Ones
Lilja is first introduced in Chapter 1 alongside her squad mates in Grave Mole. After showing results at the International Battle Standard Festival, they continue to train. Chapter 8 has Lilja and Koshka suddenly glitching out while speaking in a virtual room with Chloe, with the implication being that her brain is being studied by scientists.
In Chapter 24, Chloe and Lilja instruct some newly-deployed Gauntlet Knights and Lilja reveals that she was the crime she was pardoned for was accidentally killing some instructors when she tried to fly past them as a trainee.
In Chapter 25, Lilja is suddenly electrocuted with her shock function by Chloe and curses her out as she falls into the path of incoming missiles. Her final status is unknown.
The Data Fragments show more interactions between Lilja and her squadmates. "Scolding Withdrawal Symptoms?" shows that Lilja and Koshka were aware of Chloe's "evil" personality beforehand. "Auxiliary Major General Gustafsson" explains Lilja's verbal tics and reveals she's an important part of the Pandora Replication Experiment.
- In Phase 1: For You, the Replaceable Ones, Lilja says "Nipanipah", a variation of Rika Furude's catchphrase "Nipah~".
