The first primary character of the series, Ai Hoshino from Oshi no Ko, was introduced, but it was made clear by the end of the cinematic 90-minute first episode that she would not be the one we would follow for the duration of the rest of the run.
But Ai Hoshino had a big impact on followers, particularly thanks to some cosplay by Enako, a Japanese artist with one of the biggest fan bases, who shared her interpretation of the now-famous pop star with admirers on Instagram.
