The Most Popular Characters in Oshi no Ko (According to MyAnimeList)_7

Aquamarine Hoshino, usually going by Aqua, is the co-star of Oshi no Ko along with his twin sister Ruby. Like her, he got reborn as Ai Hoshino's child, but Aqua has a much different attitude about it. In Aqua's eyes, Ai is still just Ai Hoshino the idol, not his "mama," and he'd rather avenge her than try to be like her.

Aqua is a classic "cool guy" lead, an aloof and calculating fellow who is distinctly popular with all the girls around him. His personality is a mixed bag, since Aqua can be cold and has mild stalker tendencies, but also saved Akane's life on his own accord and is supporting Kana and Ruby with his Pieyon disguise.

Ai Hoshino the music idol embodies Oshi no Ko's central themes more than any other character, even if she didn't stick around that long. Growing up, Ai never knew love and had an unstable childhood, but she did have talent as a singer, so she became an idol. That meant burying her own misery and pretending to be happy and loving to everyone.

Ai was highly successful as B Komachi's star, but after having her two children, she started doubting herself again. She wasn't sure if her love for Aqua and Ruby was genuine, but in her dying moments, Ai realized the happy truth—that she did love them. That allowed her to die in peace, but the darkness of the Hoshino family had only just begun.

Kana Arima started off strong as a popular child actor, but then her career dropped off. Now, as a teenager, Kana has a second chance at stardom with Ruby's new B Komachi group. Even if she is the least enthusiastic member, Kana has the most power with her superior singing voice and name recognition.

Kana is a total tsundere who often loses her temper and denies her warm feelings for others, which helped endear her to Oshi no Ko fans. She also got swept up in a love triangle between herself and Akane, but even if she has a stronger personality than Akane, that doesn't mean she will win—not yet, anyway.
