Ruby Hoshino

Ruby is a beautiful young girl of average height with blonde hair that she ties in a side ponytail (much like how her late mother Ai Hoshino does), resembling her Twin Brother Aqua Hoshino and possesses pink-ruby colored eyes with a six-star on her left eye like her late mother. As her idol career progresses, she comes to gain a six-star eye in her right eye as well and this becomes a permanent addition once she starts shining as brightly as Ai did on stage. Being noted as very beautiful by others. Ruby has been stated to resemble Ai by many people, such as Aqua Hoshino and Kana Arima where Kana herself confirmed that her keen nose in industry "can sense potential in this girl" and it reminds her of Ai. The resemblance grows stronger when she wears a purple wig, to the point that it shocks others

As the daughter of her favorite idol, Ai Hoshino, takes her life to the fullest, Ruby has given herself the goal of becoming an idol singer, not only to follow in her mother's footsteps, but also to fulfill her promise to Gorou Amamiya. Unbeknownst to her, Gorou had already passed away and been reborn as her older twin brother, Aqua Hoshino. Unlike Aqua who is calm, calculated and discreet, Ruby is the polar opposite of him as she is extroverted, outgoing, loud, optimistic and communicative compared to her brooding brother. She is most apparent in the connections she makes with others. At the same time, Aqua only does this to further his agenda. She doesn't share her brother's opinion of hunting down the culprit who killed their mother, instead moving on from that incident and focusing on her dreams. She persists in this notion to the point where she often conflicts with her brother's interests. Ruby tends to speak her mind without a filter, often referring to Kana Arima as the "gourd girl" and the "girl who will lick a lying snitch," much to Kana's displeasure. Additionally, Ruby has utilized the "airhead sister" persona to her advantage in the media as a character she created to promote herself.

Ruby reveals herself to be just as methodical and cunning as her brother. After her darker turn for the sake of her revenge, Ruby adopts a two-faced attitude towards others entirely whenever she sees that she could benefit from them in the long run, She also made sure that she had Tetsu Urushibara under her thumb by manipulating him into believing that she had saved him and his job through a scandal that she had caused in secret for her own benefit. After Aqua reveals their mother's secret to the public, Ruby has a temporary break with her relationship with her twin brother because she hates him so much that he kept it from her. She is very honest to the extreme with herself and hates lies.

Ruby's greatest asset has repeatedly been noted to be her natural immense beauty. She has a charisma about her that draws people in. In addition, her mother taught her how to dance from an early age and even noted that she indeed possessed a natural talent. However, Ruby lacked in arguably the most vital area for being an idol: singing; only scoring a mediocre 38 at karaoke. She also held herself back by refusing to resort to any underhanded tactics, causing Minami Kotobuki to believe that Ruby was too "pure" for the cutthroat entertainment industry.

Due to her initially trying to emulate Ai, its noted that Ruby lacked her own passion, which prevented her from reaching her full potential. However, upon learning of Gorou Amamiya's death and resolving to avenge him, she began to radiate a murderous aura that drew people's interest. She also threw away her initial naivete and started using any means necessary to quickly rise in fame. In a way, she showed herself to be just as manipulative as Aqua, if not more so, since she was not just benefitting from scandals but actively causing them. Over time, her singing ability also improved substantially with it now rivalling Kana and Mem-Cho's. Despite her mysterious and often murderous demeanor , Ruby overall is still the cute, ditzy and sweet singer of B-Komachi who shines just as bright as her mother
