Appearance

Natsumi’s full apperance.
Natsumi has a slim, graceful figure complemented by her stunning blonde-to-pink ombré hair, which is styled in twin braids with small bows at the front. A delicate white flower is tucked above her right ear, adding a touch of elegance to her look. Her hot pink eyes add a striking and vibrant flair, perfectly reflecting her energetic personality.
Personality
Natsumi has a friendly and approachable demeanor, but beneath that, she can be manipulative and self-serving. Initially, she joins Liella! with the intent to capitalize on their growing popularity, hoping to gain money and internet fame through ad revenue as a social media influencer. Much like Sumire, Natsumi spent her childhood pursuing various entertainment careers, but her focus was always on financial gain rather than passion. However, after spending more time with the group and enjoying a weekend at the Sakurakoji family’s cabin in Hokkaido, Natsumi begins to genuinely appreciate the charm of school idols and starts to develop a true connection to her role.
Natsumi is particularly supportive of Tomari, frequently praising her whenever the opportunity arises, showing a more nurturing side to her character.
Natsumi has a unique speech pattern, often ending her sentences with “~desu no,” adding a distinctive touch to her dialogue. Her catchphrase, “OniNatsu!” reflects her playful and spirited personality.
Background
Before becoming a school idol, Natsumi was a small-time L-Tuber, hoping to gain a larger following and earn more money through her channel. Her ambitions took a hit when she lost a significant portion of her savings in the stock market, prompting her to take on various part-time jobs to make ends meet. These jobs include working for “Lber Eats” and a moving company, as shown in Season 2, Episode 3 and Season 2, Episode 4, respectively.
In Season 2, Episode 5, it’s revealed that Natsumi’s L-Tuber channel didn’t attract many followers, which leads her to take a new approach: becoming a “producer” for Liella! and uploading vlogs of the group on her L-Tube channel. With the group’s growing popularity, these vlogs generate more views than her own content, providing Natsumi with the financial boost she’s been seeking.
Natsumi also has a younger sister, Tomari Onitsuka, who adds an extra layer to her family dynamic.
Clubs and Hobbies
Natsumi is a multi-faceted individual with a variety of side jobs and hobbies, all motivated by her desire to earn more money. She is an L-Tuber, creating content in hopes of growing her online presence. In addition, she works as an Lber Eats delivery driver and has recently started working for a moving company called Sunshine Moving. Beyond these jobs, Natsumi serves as the producer for Liella!, managing and uploading vlogs of the group’s daily lives on her L-Tube channel to attract more viewers. All of her hobbies and pursuits are driven by her goal of increasing her income.

Etymology
The name Natsumi combines the kanji “夏” (natsu), meaning “summer,” and “美” (mi), meaning “beautiful,” together conveying the idea of a “beautiful summer.”
Her surname, Onitsuka (鬼塚), is derived from the kanji “鬼” (oni), meaning “demon” or “ogre,” and “塚” (tsuka), meaning “mound,” “hill,” or “pile.” The combination evokes a sense of strength or power, reflecting her bold and sometimes fiery personality.
