Sumire Heanna

Accessories and Style
The Headband: She almost always wears a bright red headband. This accessory is iconic to her character and is used to pull her bangs back during action or practice.
School Uniform: When she wears the Yuigaoka Girls' Academy uniform, she usually wears it impeccably, maintaining that "showbiz veteran" image.
Casual Clothing: Her personal style tends to be modern and fashionable, reflecting her ambition to be a star, although it is also very common to see her in the traditional miko outfit (white tunic and red hakama) when she helps at her family's shrine.
Typical Expressions
He usually has a look of absolute confidence (or feigned arrogance) with a self-satisfied smile.
However, she is very famous for her comical expressions, especially when she gets scared, frustrated with Keke, or when someone mentions her past as an "isopod," at which point her eyes become circular and she loses all her diva composure.

Hair: It's her most distinctive feature. She has long platinum blonde hair in a "hime" style cut, consisting of straight bangs and side strands leveled at cheek level, while the rest of her hair falls long down her back.
Eyes: Her eyes are a very bright emerald green, which stands out a lot with her hair color.
Height: She is one of the tallest members of the original group, which gives her a slender and sophisticated presence on stage.

His Role in Liella!
Professional Experience: Having grown up in the industry, he brings a more realistic and technical perspective on how to behave in front of the cameras and on stage.
Dynamics with Keke: Her "love-hate" relationship with Keke is one of the comedic pillars of the series. Despite their fights, they both deeply respect each other as artists.
Peak Moment: Her evolution reaches its peak with the song "Nonfiction!!", where she finally takes center stage, demonstrating her talent for dance and rap, leaving her fears behind.

Personality and Background
The "Eternal Sideshow Girl": Unlike her co-stars, Sumire has been in show business since she was a child. However, she always carried the frustration of being cast in minor or unglamorous roles (like her famous giant isopod costume), which made her feel very insecure.
Diva facade: She often appears arrogant, competitive, and obsessed with being the "center" of the group. This attitude is actually a protective layer to hide her fear of failure and her desire to finally be recognized.
The Shrine Girl: Her family owns a local shrine where she regularly volunteers. Seeing her in her traditional miko (shrine maiden) attire amusingly contrasts with her obsession with fame and the glitz of idols.
Hidden Loyalty: Although she constantly argues with Keke Tang, Sumire is extremely perceptive. She's one of the first to notice when someone in the group is discouraged and often helps indirectly, while maintaining her pride.
