Aquamarine Hoshino

Coldness, strategic intelligence, and a profound emotional detachment driven by revenge. He is a methodical strategist (INTJ) who manipulates situations to achieve his goals, though he shows a protective and caring side towards his sister Ruby and others. Vengeful and calculating: The death of his mother, Ai Hoshino, is the driving force behind his actions. He is willing to use any means necessary, including manipulation and acting, to find the person responsible. Strategic Intellect (INTJ): Possesses an analytical mind capable of anticipating hidden intentions and planning for the long term, excelling in the entertainment environment. Emotional Detachment: He often appears melancholic or cold, keeping people at a distance, which contrasts with his genuine concern for Ruby Hoshino. Overprotective: He acts like a very protective older brother to Ruby, trying to prevent her from suffering the same fate as her mother, sometimes limiting her opportunities out of fear. Internal Conflict: He combines the maturity of his past life (as the doctor Gorou Amemiya) with the vulnerability of his current situation, showing a constant struggle between his obsession with revenge and his desire to protect his loved ones. Talented at Acting: He uses his acting skills not only as a tool for manipulation, but also to cope with his emotional traumas. In short, Aqua is a trauma-driven character who hides her vulnerability under a mask of strategic coldness, seeking justice at any cost.

Ruby Hoshino - Twin Sister Ai Hoshino-du, mother who died

Because he is Ai's son, many people were able to point out their similarities despite not knowing his pedigree. Much to Aqua's dismay, as before Chapter 105, she wanted to prevent the truth about her late mother from becoming known to the general public. B is portrayed as someone with a sister complex, which is understandable since he was initially unwilling to let his sister become an idol and suffer the same fate as their mother. Therefore, he subtly sabotaged almost all of Ruby's chances of promotion due to this overprotective nature, despite knowing how much she longed to follow in her mother's footsteps. Ultimately, he helped Ruby and the new group B-Komachi prepare for a concert so they could accomplish a task long thought impossible. He was also a major driving force behind a project that served to salvage Akane Kurokawa's reputation. Aqua is Akane Kurokawa's boyfriend (in the anime), but their relationship is purely for public image/work-related purposes and not based on genuine feelings. However, Akane did indeed fall in love with Aqua.

Aqua

Aqua has blond hair, is relatively tall, and has aquamarine eyes, which his mother named him for. He often changes his appearance due to his work as an actor. Aqua is described as "handsome" and has a star in his right eye, symbolizing that he and his sister are halves of their mother. As a child, Aqua was often called cute by those around him.
