海外出身の新入生。歌やダンスの経験はなく、いつも自信がなさそうに縮こまっている。才能があるようには見えないが、アイドルへの憧れは本物で、相当な努力家。親友の清夏とは、一緒にステージに立つ約束をしている。 A new student from overseas. With no experience in singing or dancing, she lacks confidence and is always timid. She doesn't seem to have much talent, but her longing to be an idol is sincere, and she is a hard worker. She and her best friend Sumika have made a promise to perform on stage together.

Introduction
A cute-type idol who works hard from scratch with great aspiration, her image color is #EFFDFF。
- A mixed-race girl with a Japanese father and a Swedish mother, she originally lived in Sweden and had no connection to idols. For a certain purpose, she came to Japan and enrolled in Hatsuboshi Gakuen without any prior foundation in idol activities.
- She appears to be easily intimidated; before enrolling, she declined due to a lack of confidence, but after watching a performance at the school with a friend, she felt a sense of longing, which became her motivation to become an idol.
- Although she lacks confidence, her admiration for becoming an idol is sincere, which is why she persuaded her parents to come to Japan, a foreign land, to study.
- During a chance encounter with the Producer, she discussed her situation and was encouraged that a strong will and sufficient courage are what matter most, thus taking her first step toward becoming an idol.
- A balanced pentagon-stat character, but with no particularly outstanding traits; she belongs to the "Good Impression" system that fits her character design, being the type who accumulates strength over time to achieve success.
- She looks timid on the outside, but is actually very strong-willed inside, gradually revealing her "soft on the outside, tough on the inside" nature later on.
|
- Despite having a perfect smile in her natural state, her smile during early practice sessions was very stiff, which nonetheless served as another kind of simple and cute expression,
narrowly missing out on becoming a comedian. After realizing that a straightforward smile is the best smile, it became one of Lilja's strengths (consistent with the "Good Impression" game mechanic).
- During an incident where she was mocked by passersby, Lilja confessed that she was well aware of her lack of talent, stating, "But that's just the premise of me becoming an idol—it can't be the reason for me to give up," further strengthening her resolve to never quit and putting in even greater effort.
- Under the Producer's guidance, she initially overcame her nervousness and timidity about performing in front of crowds, showing the audience her hardworking self and a heart-moving presence. Subsequently, Lilja took the initiative to invite a friend as an audience member, wanting Seika to see her current self, which became the catalyst for completely overcoming her cowardice.
- She has few interpersonal relationships,Sumika Shiunis her one and only best friend. Lilja's reasons for becoming an idol and working desperately hard include the determination she wants to convey to Seika, hoping she won't give up on the path to becoming an idol. As Lilja grows, the Producer also becomes an indispensable pillar for her and a key figure in successfully creating miracles.
- To make up for the gap between herself and others, she voluntarily practices late into the night every day. Upon learning about her first official performance, she overtrained due to worries about her abilities; this overexertion almost led to an accident. The next day, the Producer took her to watch a performance to relax her mind and body, which also helped her remember her original motivation for becoming an idol.
- She had once made a promise with Seika to become idols together, but Seika, due tosome reasonsgave up, but in her personal story arc, Lilja inspires Sumika through her own persistence and successfully manages to keep their promise alive[1]。

Trivia
- She is not good at tongue twisters, and inKotone Fujitafront of them, she failed miserably when she tried.
- She is very good at making pastries and doesn't gain weight no matter how much she eats, which makesTemari Tsukimuraextra envious.
- She makes breakfast in the morning and only wakes up her late-rising roommateSumika Shiun, preventing Sumika from oversleeping and being late; she is very reliable.
- She is not good at socializing and is very shy, but her willpower is quite strong. Combined with her inability to read the room, she can sometimes exert a level of interpersonal destructive power akin to a "social terrorist."
- She considers the socially adeptMao Arimurato be like a prince. In an official interview at the game's launch, the two were designated as having a "Princess and Prince" dynamic.
- Her Japanese is quite fluent, but her understanding of Japanese culture and social atmosphere is still insufficient, requiring extra tutoring.
- Although she rarely has the chance to mention it, she is actually an anime otaku. Her favorite anime is the magical girl-themed "ふわっとブレザーつむじちゃん" (Fluffy Blazer Tsumuji-chan), and she also likes robots and has a longing for maid cafes. She once went to a comic convention to cosplay with Sumika and often quotes anime lines when speaking.
- She is good at many video games and tookSaki Hanamias her apprentice; she even holds the legendary "Mammoth" rank in a certain fighting game
, so Saki almost called her "Legendary Mammoth-san", but she is too shy to make it public. Regarding idol activities, she receives guidance from Saki, and with her help, she communicated with Sumika to resolve Sumika's inner conflict.
- Sometimes she suddenly becomes very hot-blooded[2]。
- According to Sumika's assessment,[3], her cheeks feel great to the touch,
she is a daifuku.
- Setting aside her mixed-race trait, Lilja's character design closely resembles the original Red Center of the IM@S seriesHaruka AmamitoYukiho Hagiwara,combination, so she is jokingly called the "True Red Center" of this work (compared to the
SaiyansHanami sisters, whose designs deviate from tradition). The "starting from zero" setting and the independent character routes in this work make many long-time fans reminisce about their time at 765 Production.
- Her solo song style is J-Pop.
