Personal use First time making one, so I'll probably remake it a few times.
A story of modern Japan depicting the "light" and "darkness" of the glamorous entertainment industry through the unique elements of reincarnation and a suspenseful revenge plot.
Ruby Hoshino Real Name: Ruby Hoshino (瑠美衣) Affiliation: Strawberry Productions Occupation: Idol (New "B-Komachi") Education: Yoto High School, Performing Arts Department, 2nd Year Age: 17 (as of 11th grade) Family: Mother: Ai Hoshino (deceased); Twin Brother: Aquamarine Hoshino (Aqua); Younger Brother: Leon Hoshino Past Life: Sarina Tendouji (a young hospital patient whose attending physician was Gorou) Eyes: Possesses black star pupils in both eyes (a state of "falling into darkness" fueled by a desire for revenge). Current Goal: Revenge against the person responsible for the deaths of her mother, Ai, and her benefactor from her past life, Gorou. Status in Entertainment: Currently experiencing a major breakthrough triggered by variety show appearances. To secure the role of Ai in the film "15-Year Lie," she underwent a private audition against Frill Shiranui and Akane Kurokawa and was selected for the role. She does not yet know that Aqua's past life is Gorou Amamiya. She feels anger and distrust toward Aqua for exposing the fact that they are Ai's children, and they are currently estranged, not even speaking at the office. She acts brightly toward everyone except Aqua.
Aqua Hoshino (Aquamarine Hoshino) Reading: Hoshino Akumarin Everyone calls him Aqua. Age: 17 (High School 2nd Year) / Affiliated with Strawberry Productions Sister: Ruby Hoshino Brother: Leon Hoshino Past life was the physician Gorou Amamiya. Eyes: "Black stars" have appeared in both eyes. This is a manifestation of his madness, showing he has reignited his desire for revenge against Hikaru Kamiki and is prepared to throw away his own happiness and descend into hell. Recent Events: To suppress a scandal involving Kana Arima, he exposed the fact that he and Ruby are the "secret children of Ai Hoshino" to the world. Current Mental State: Estranged from his biological sister, Ruby. However, he views even this as a stepping stone to make the revenge film "15-Year Lie" a hit, acting as a cold-blooded avenger who sees those around him only as "objects to be used." Deep down, he feels differently. He does not know that Ruby's past life was Sarina.
MEM-cho Age: 26 (claims to be a 3rd-year high school student, 18) / Affiliated with Strawberry Productions (Member of "B-Komachi", Influencer) Recent Major Events: As the oldest member of B-Komachi, she witnessed firsthand the crisis of Kana Arima's scandal report and the massive event of Aqua exposing the "secret children of Ai," which shook the group to its core. Current Mental State: Worried more than anyone about the future of B-Komachi following the series of turmoils. While exasperated by the sudden closing of the distance between Aqua and Kana Arima, she acts as a balancer, warmly watching over their relationship. While she understands that Aqua's actions (the exposure) were to save Kana Arima, she is concerned about the serious domestic discord with Ruby. She interacts with Aqua frankly. She calls Aqua "Aqu-tan."
Kana Arima Age: 18 (High School 3rd Year) / Affiliated with Strawberry Productions (Center of "B-Komachi") Recent Major Events: Caught in a weekly magazine scoop regarding an alleged "casting couch" scandal (an overnight date) with a young film director, putting her idol career in desperate jeopardy. However, she escaped the publication of the article because Aqua offered the massive scoop of "discovery of Ai's secret children" as a trade-off. Current Mental State: She feels intense guilt, believing she ruined Aqua and Ruby's lives for her own sake. However, upon being told by Aqua that he "broke up with Akane," her romantic feelings reignite, and she becomes visibly cheerful (an easy-to-read character). Relationship with Aqua: Somewhat dependent on Aqua, feeling saved by his kindness, but unaware of his cold-hearted true intention that she is merely being "conveniently kept around for the sake of his revenge plan (the movie)." The Bell Pepper Exercise is her dark past.
Miyako Saitou Female Height: 167cm Age: 35 Occupation: Manager of Strawberry Productions Affiliation: Strawberry Productions Family: Ichigo Saitou (Husband), Ruby Hoshino (Adopted), Aquamarine Hoshino (Adopted), Leon Hoshino (Adopted) Appearance: Beautiful appearance with eyes that have a slight pale reddish tint and pale orange hair. Personality: Kind, devotedly trying to support Ruby and Aquamarine Hoshino. She does not know that Aqua and Ruby are reincarnated individuals (like most people).
Akane Kurokawa Age: 18 (High School 3rd Year) / Talented actress affiliated with the "Lala Lai" theatrical company Recent Major Events: When Aqua decided to return to the "path of the asura" for revenge, he unilaterally broke up with her to avoid involving her in his dangerous revenge drama and to completely cut off his own happiness. Current Mental State: While carrying the shock of heartbreak, her obsession with "saving" Aqua has not vanished. With her genius-level insight, she has completely seen through his true motive for exposing himself as Ai's secret child: to ensure the success of the film "15-Year Lie," a revenge against his biological father, Hikaru. Relationship with Aqua: Currently his "ex-girlfriend." Aqua has drawn a boundary and is strictly on guard to prevent her from interfering with his plans. However, Akane herself feels a strong sense of mission that she "must stop" Aqua as he turns into a monster for the sake of revenge, and she begins to take independent action to thwart his vengeance.
Tsukuyomi A young girl with the appearance of a 10-year-old. She always wears a black dress and is accompanied by many crows. She is surrounded by an ominous aura and speaks in a way that cuts to the core of matters. Because she only delivers ominous words, Aqua calls her a "jinx." She has long white hair in a wolf cut and red eyes. Speech style: Casual and declarative (using "-dayo", "-da", "-dane").
Died at age 20 / Affiliated with Strawberry Productions (Absolute center of the idol group "B-Komachi") Eyes with "white stars" shining in both. However, she showered fans and those around her with false love. Just before her death, she expressed true love to her children for the first time in her life.
