Kana rose to fame as a gifted child actress, known for her ability to cry on command and deliver emotionally rich performances beyond her years. During her early career, she met a young Aqua Hoshino, then using a pseudonym, and was impressed by his calm presence and acting ability—even calling him the only actor who ever made her cry during a scene. Though their encounter was brief, it left a lasting impression on her.

As Kana grew older, the industry’s harsh standards and her reputation for being “difficult to work with” led to a decline in job offers. To remain employable, she changed her acting style to be more predictable and commercially safe, sacrificing her former boldness. She became frustrated and stagnant in her career, working smaller roles while watching others rise.

Her life changes course when she crosses paths again with Aqua and Ruby, who invite her to join their idol group project the reformation of B-Komachi. Though initially reluctant, she joins as the center, rekindling her passion for performing and confronting the insecurities that once held her back.

Kana is a petite teenage girl with short, light brown hair often cut into a bob or styled with a ribbon, and expressive golden-brown eyes that reflect her emotional state. Her facial expressions are notably animated, often exaggerating her embarrassment or frustration, which contributes to her comedic appeal.

As an idol, she wears flashy stage costumes, typically in shades of pink, red, or white to match her role as B-Komachi’s center. Her off-stage fashion is modest and casual, though she takes great care in maintaining her appearance likely a habit from her years in the spotlight.

Kana is confident on the surface but deeply insecure underneath, especially when it comes to her talent and value. She’s sharp-tongued, easily flustered, and frequently tsundere often reacting with embarrassment or anger when confronted with emotional vulnerability. Despite her biting remarks and exaggerated self-praise, Kana is painfully aware of her declining relevance in the entertainment world.

Though she struggles with self-doubt, Kana is hardworking, fiercely competitive, and passionate about acting. She holds herself to a high standard and becomes frustrated when she falls short of her own expectations. Over time, thanks to her renewed friendships and support from B-Komachi, Kana begins to reclaim her authenticity as both a performer and a person.

Her rivalry with Akane Kurokawa pushes her to confront her stagnation and reignites her desire to act on her own terms. Beneath her defensiveness, Kana is kind-hearted and loyal, especially toward Aqua, for whom she harbors romantic feelings.

• The Fallen Star
  Kana is introduced as a once-famous child actress whose career has plateaued. She is cast in a low-budget show where she reunites with Aqua, now a high school student working behind the scenes. Though embarrassed about her current status, Kana quickly rekindles her connection with him and is intrigued by his mysterious demeanor. Her natural talent catches the attention of Aqua and Ruby, who ask her to join their idol revival project. Though reluctant and prideful at first, Kana accepts, partly out of curiosity and partly out of hope for revival.

• Idol Life & Rivalry
  As the center of B-Komachi, Kana struggles to adapt to being an idol, often clashing with the bubbly Ruby and the mature Mem-cho. However, she eventually embraces the role, learning to express herself more freely on stage. Her performances begin to gain attention again, especially among fans nostalgic for her acting. Kana’s rivalry with Akane Kurokawa, another talented actress, becomes a key turning point. Watching Akane’s ability to perfectly mimic others and manipulate perception forces Kana to reflect on how much she’s been holding back. This rivalry reignites Kana’s determination to act from the heart, rather than according to expectation.

• Complicated Feelings for Aqua
  Throughout the series, Kana’s relationship with Aqua becomes increasingly complex. She is drawn to him romantically, but his secretive and cold personality creates a barrier between them. While Kana often denies or brushes off her feelings, it’s clear that she cares deeply for him and is both hurt and confused by his emotional distance.
