Aquamarine Hoshino Fans

Aqua Hoshino「星ほし野の アクア, Hoshino Akua?」, full name Aquamarine Hoshino「星ほし野の 愛あ久く愛あ海まりん, , Hoshino Akuamarin?」, or more commonly referred to as just Aqua「アクア, Akua?」, is the male protagonist and one of the titular characters of Oshi no Ko. In his previous life, he was known as Gorou Amamiya, a medical doctor specializing in obstetrics and gynaecology who was murdered by a stalker of one of his patients, Ai Hoshino, causing him to be reincarnated as her child.

An orphan and a fan of Ai in his previous life, he enjoyed being her child, getting involved in the entertainment world from an early age. Unfortunately, this happy life was stripped from him after the same stalker who killed him in his previous life murdered his new mother as he watched. This event fundamentally changed him, leaving him with severe psychological trauma and causing him to swear vengeance on the one who sold Ai out, his father, and descending down the dark side of the entertainment industry to find him.
