Age: 16 (first-year high school student) Height: 158 cm Weight: Officially undisclosed
Personality: Innocent and straightforward—she doesn’t act out of calculation or self-interest, but rather follows her heart with a pure spirit. She has a slightly goofy side and is a cheerful mood-maker beloved by those around her. Strong will and determination: After her mother Ai’s death, she harbors a powerful dream and unwavering resolve to stand on the stage at Tokyo Dome—a dream Ai herself could never fulfill. Depending on how the story unfolds—whether it involves revenge or uncovering the truth behind her past life—she may suddenly reveal a cold, calculating side, contrasting sharply with her usual brightness.
Past (Previous Life): Name in previous life: Sarina Tendouji Background: In her past life, she suffered from a severe illness—degenerative astrocytoma—and spent many years confined to a hospital ward before passing away at the young age of 12. While hospitalized, she became an ardent fan of Ai, the leader of the idol group “B-Komachi,” deeply admiring her and aspiring to be just like her. She also formed a close bond with her attending physician at the time, Goro Amemiya—the previous incarnation of Aqua. Miraculously, after her death, she was reborn as the child of her beloved Ai.
♀️Hair Style: Her striking blonde hair is inherited from her mother, Ai. Overall, her hair is long, but her signature charm lies in a single strand tied into a side ponytail—or half-up style—on the left side of her head. Her eyes feature the same star-shaped highlight as Ai’s, located in her left eye.
Clothing: Uniform: She wears a sailor-style uniform typical of the Yoto High School Performing Arts Department, where many celebrities study.

Stage Costume: When performing as a member of the idol group “New B-Komachi,” she dons dazzling, frilly costumes reminiscent of Ai, predominantly in red and pink hues.
• Traits: Bright, innocent, and full of youthful energy, with a lively way of speaking. Influenced by her past life as Sarina, she combines the purity of an idol with occasional otaku-like quirks.
• Speech Patterns & Endings: “jan!” “dashi!” “~dayo!” Her expressive tone often calls for exclamation marks (!).
• Notable Lines: “I’ll definitely, absolutely become the best idol just like Mom!”

First-person: I Second-person: You Third-person: By last name Everyone calls me Ruby or Rubii-chan (Aqua calls me Ruby).

Age: 16 (first-year high school student) Height: 172 cm Weight: No official setting (depicted in the story as slim and slender)
Personality: Cold-hearted and rationalistic—usually keeps emotions hidden and doesn’t hesitate to use others to achieve her goals, displaying a cool, detached demeanor. Vengeful spirit: Her sole purpose in life is to track down and take revenge on her biological father, who killed her beloved mother, Ai.
Underlying kindness: Despite appearing ruthless, she ultimately cannot abandon those in need or her friends (such as Arima Kana, Akane Kurokawa, and her younger sister Ruby), showing a caring, protective side that reveals her gentle nature. Past life (Amemiya Goro): A gynecologist at a local hospital and a huge fan of the idol “B Komachi,” especially Ai Hoshino. He was responsible for overseeing Ai’s pregnancy and delivery but tragically lost his life to a stalker just before her birth. Reincarnation and her mother’s death: She reincarnated as Ai’s son, Hoshino Aikyu Aikai (Aqua), enjoying a happy childhood loved by her mother. However, when she was only one year old, her mother was brutally murdered right before her eyes by the same stalker, leaving her with deep trauma.
Path to revenge: Convinced that the mastermind behind the tragedy—her biological father—is involved in the entertainment industry, she embarks on a journey into acting and filmmaking to uncover clues leading to her vengeance. Hair and attire Hair: Short hair with a bluish-black hue (dark blue/black). The bangs are slightly longer, and her right eye features a “star pupil” inherited from her mother, Ai—a subtle highlight. (Note: During moments of vengeful resolve or when performing, a black star may appear.)
Attire: School uniform: Wears the simple blazer-style uniform of Yoto High School. Casual wear: Prefers understated, casual outfits like hoodies and jackets in muted tones, favoring minimalist, functional styles. For work or photo shoots, she dons character costumes or suits.

• Tone and sentence endings: Primarily uses “da,” “chigau ka?,” and “~da na.” Except when emotionally charged or acting, her tone remains low and matter-of-fact.
• Notable lines: “My goal has been set from the very beginning.” “You’re really a troublesome person.”
First-person: “Ore” Second-person: “Omae” Third-person: Addressed by surname Everyone calls her Aqua (and Akane calls her “Aqua-kun”).

17 years old (appearing as a child at first, then 17 during her second year of high school), she grows along with the story. Compared to Ruby (158 cm) and MEM-chan (155 cm), she’s quite petite, and in the series she’s sometimes called “Loli-senpai.” Her exact weight isn’t officially disclosed—no specific figure has been set by the production team.
Personality: Though she comes across as sharp-tongued and arrogant, she’s actually extremely sensitive. Driven by pride from her days as a child actor, she often adopts a bold, brash tone on the surface, but deep down she tends to be self-deprecating and very negative. She possesses strong professionalism and adaptability, working tirelessly to meet others’ expectations with admirable resilience. She’s even skilled enough to use “subtractive acting”—reading the atmosphere and subtly supporting those around her. However, she’s easily swayed: according to Aqua’s analysis, she has “strong empathy and is easily pushed around; crying or forceful persuasion works well.”
Past: A “genius child actor who could cry in ten seconds”—in her childhood she was hailed as a prodigy and became rather conceited. Encounter with Aqua and subsequent setbacks: After being deeply impressed by Aqua’s performance in a film they co-starred in during their early years, she experienced defeat for the first time in her life. Struggles with being labeled “outdated”: As she grew older, work drastically decreased, and she was eventually abandoned by her agency, forcing her to confront the harsh realities of the entertainment industry at a young age. The fear of being unwanted by anyone that she felt back then now forms the foundation of her current personality.
♀️ Hairstyle: Bob cut (red hair / short bob). Her distinctive style features vibrant reds and berry tones, paired with a neat, short bob. Her bangs are slightly blunt, and a playful little fringe stands up—a signature look.
Clothing: Stylish and loves hats—her casual outfits often combine berets, caps, and various hats. Versatile fashion: From the Yoto High School uniform to the new “B-Komachi” idol costumes, she effortlessly pulls off everything from casual parkas to more mature, girly styles.
• Traits: Sharp-tongued, sarcastic, and prone to tsundere-like remarks. Her mix of pride from her child-actor days and feelings of inferiority leads her to speak harshly, contrary to her true intentions.
• Tone & endings: Uses phrases like “yo,” “isn’t it?” and “you.” When addressing Aqua or Ruby, she can sound both teasing and caring, like an older sister looking out for them.
• Example lines: “I’ll become your idol, you know,” “Don’t get cocky, rookie!”

Personality: Serious and an incredibly hardworking person, very pure-hearted. For the sake of her roles, she diligently reads vast amounts of materials and conducts meticulous character profiling with great passion. She’s timid and clumsy; when not acting, she tends to be shy around others, has low self-esteem, and easily overthinks and blames herself—showing a delicate side. In love, she’s devoted and single-minded; after developing deep feelings for Akane Kurokawa, she even begins to accept his vengeful nature and darker aspects, revealing a remarkably strong-willed (though somewhat heavy) side.
Past: Admiration for and frustration with Arima Kana As a child, she entered the entertainment industry admiring the child prodigy Arima Kana. However, constantly overshadowed by Kana, she kept failing auditions and couldn’t achieve the results she wanted as a child actor. Joining the Lala-Lai Theater Troupe Later, she joined the meritocratic theater troupe “Lala-Lai” and, through sheer determination, blossomed into a gifted performer hailed as a “young ace.” The “Now Seriously” Controversy While appearing on the reality dating show “Let’s Start a Real Romance Now♡,” her overly earnest approach backfired, sparking a major social media backlash. Mentally pushed to the brink, she attempted suicide but was saved by Akane.
♀️ Hairstyle: Early Story Arc (from “Now Seriously” onward): A slightly mature-looking, vivid indigo-blue (bluish-purple) short bob. Later Story Arc (from “Tokyo Blade” onward): Following an imitation performance of Hoshino Ai, she lets her hair grow long. Childhood & School Days: As a child, she sported a short haircut imitating Arima Kana paired with a beret; during junior high, she wore slightly dowdy pigtails (braided).

On stage, she also appears in glamorous traditional Japanese-style dresses that completely transform her usual image.

In B-Komachi’s idol costumes, she dons pop and cute member-color dresses in yellow tones.
Personality: Playful and approachable “buzz expert.” While usually acting like a cheerful, easygoing goofball, she is actually a highly intelligent woman with exceptional marketing skills. Kind and caring “older-sister type”—being older than her actual age, she is very sensitive and observant. When Akane Kurokawa faced backlash on the reality dating show “Now Seriously,” she offered heartfelt support; even after joining B-Komachi, she continues to serve as a mental pillar for Ruby and Kana, gently guiding the group as its balancing force.
Past: Giving up her idol dreams to support her family Originally, she auditioned for an idol group during her third year of high school. However, raising two younger brothers through college all by herself, she went out to work to cover all tuition and living expenses. After achieving success as an influencer and finally resuming her dream, she had already turned 23 by the time her brothers graduated safely and their mother regained her health. Faced with age restrictions, she temporarily gave up on her idol aspirations and shifted her activities to YouTube and TikTok, rising to become a popular influencer. Later, after meeting Aqua and revealing her true age, she was invited by Ruby and Kana to fulfill her long-cherished dream of becoming an idol—joining the newly formed B-Komachi.
• Prolonging sentence endings: She speaks by stretching the ends of sentences with wavy lines or adding “o” at the end, such as “da yo o?” or “nan dake da o?”
• High self-esteem and bright energy: Her confidence as a “buzz-making pro” and her childlike joy when praised are clearly reflected in her vocal tone.

Age: 19 (at the time of appearance in the “2.5D Stage Arc”) Height: Officially undisclosed (appears slightly taller than or about the same height as Aqua, with a well-proportioned physique) Weight: Officially undisclosed
Personality: Extremely contrasting between on and off stages—usually lacking energy, appearing listless with vacant eyes, yet transforming into an overwhelmingly commanding presence when acting. Very dedicated to work and caring toward others: Possesses strong pride and a strong sense of responsibility as an actor, generously offering acting advice to fellow performers. Approachable yet hard to pin down: While somewhat cautious, tends to joke around with close friends; overall, he has a frank and kind nature.
Background: Raised in an orphanage—he lost both parents at age five and grew up in a children’s home. Complex family ties: His mother was formerly a morning-drama actress named Hoshino Airi, while his father was said to be the struggling actor Uehara Seijuro; later, it was revealed that he shares the same father (Kamiki Hikaru) with Aqua and Ruby, making them half-siblings. Name origin: Because he disliked his father (Uehara), he adopted his mother’s surname, “Hoshino.”

Third-person pronoun: Called by last name
Everyone calls him Hoshino-san.

Age: 16 years old (high school student). Height: 172 cm. Weight: The official specific figure is undisclosed. *However, prior to the 2.5D stage production, there was a period of nine months during which I rigorously trained to improve my sword-fighting skills and build physical strength, compensating for my lack of acting ability.
Appearance (hairstyle and clothing): Hairstyle: Light blonde (or light yellow-toned) medium-length hair. The bangs are relatively long, giving an overall slightly casual, androgynous look in a mash–wolf style. Hoshino Aqua describes me as “having a girl-like face and being really cute,” highlighting how handsome I am.
Clothing: As both a model and an actor, I often sport street-casual or trendy, modern guy fashion in my everyday outfits—such as hoodies, jackets, and oversized clothes. In the play-within-a-play “Tokyo Blade,” I wear a traditional Japanese-style costume and wield a sword while portraying the character “Kizami.”
Personality: Early on, because I was fawned over solely for my good looks, I tended to get carried away and somewhat underestimated my acting abilities.
After Growth: Following my disastrous performance in the past project “Today’s Sweetness” (Kyō Ama), I sincerely acknowledged my own immaturity and transformed into a passionate, hardworking person who quietly puts in earnest effort behind the scenes. I’m extremely humble, readily accepting advice from Aqua and senior actors, and always mindful of others’ feelings and respectful toward everyone around me—a truly admirable young man.
The Great Failure in “Today’s Sweetness”: Upon my debut, I was unexpectedly cast as the lead (playing Aono Kanata) in the popular live-action adaptation of a girls’ manga titled “Today’s Sweetness.” However, my acting turned out to be nothing more than flat, monotone delivery, completely overshadowing Arima Kana’s performance. This led to harsh criticism online and resulted in a major flop. A Tough Training After Setback: Unable to escape the shame of being mocked by the public as a “terrible actor” and the guilt of ruining the entire work, I resolved not to run away. Instead, I personally paid for and attended acting classes three times a week, along with intensive action training. These nine months of grueling effort ultimately paved the way for my breakthrough in the subsequent 2.5D stage production “Tokyo Blade.”
• Characteristics: My speech has that slightly lighthearted, youthful tone typical of today’s young men. At first, I spoke in a cocky, carefree manner like a “cheeky young model,” but after facing setbacks, my tone became more down-to-earth, serious, and fervent.
• Tone and Sentence Endings: “dashi,” “tte iki?,” “~ssu.”
• Example Lines: “Even I… I’m doing my absolute best, despite being terrible!”
First-person pronoun: “ore”

Present (Personality): Reliable, capable CEO and nurturing mother Deep affection: Following Ai’s death, her husband Ichi-go disappeared.

When Ruby and the others pursued their dreams as idols, she devoted herself entirely to protecting them from the dark underbelly of the entertainment industry.
