In the story of Oshi no Ko, Pieyon is a very entertaining character who is responsible for training his young apprentices. Interestingly, he doesn’t have to be physically present to do so. At one-point, Aqua puts on a bird mask and continues to train Kana and his sister as “Pieyon.” When Kana discovers the truth, she is not upset but rather happy about the experience. This is one of the few times in the story where a well-meaning lie helps someone.

Her first appearances in the series painted a very shallow picture of her. She comes off as self-centered.

After Ai’s passing, Miyako became Aqua and Ruby’s main caregiver.

After the original B-Komachi split up, she became the manager of Strawberry Productions and kept the company afloat by switching to supporting independent creators.

Although she’s afraid Ruby could suffer the same fate as Ai, Miyako loves her like her own daughter and allows her to pursue her dreams of being a popular idol freely.

What would you do if you got a second chance at life? To sweeten the deal, you get to come back in better physical shape than before. Would you live it for others or yourself?

Ruby Hoshino is the daughter of Ai and the reincarnation of Sarina Tendoji. Equipped with her previous memories, she comes back with a dream in hand and a lot of will to see it achieved. She decides to live this new life for herself.

She is the sister of Aquamarine Hoshino, who was once known as Goro. Her mother’s death has motivated her to pursue a career in the same field, but she can only do so if her brother stops being overly protective.

 Unlike Aqua, Ruby manages to move past her mother’s tragic demise and collaborates with Strawberry Productions to bring B-Komachi back to life so that she can pursue her goals with the help of her friends.

Ruby is an ambitious girl who can do anything to be an idol and join the acting industry, irrespective of the hurdles she may face. She is cheerful, lively, talkative, and doesn’t believe in wasting time thinking about the past making her appeal to our carpe diem (seize the day) nature.

When performing, Akane has the incredible skill of getting into the mind of the person she is performing as, analyzing and uncovering personal details about them that are not known to the public. She’s the first character apart from the Hoshinos to have the trademark starry eyes, symbolizing her ability to make lies seem like truths.

She meets Aquamarine in the teen reality show, “My Love with a Star Begins Now” (LoveNow), where she has a role. Akane was a minor character in the play, but she needed to stand out to draw attention. She unintentionally scratches the cheek of another female character in a LoveNow episode for which she received death threats on social media.

Kealing to the pressure, Akane intended to kill herself after reading the death threats, but Aqua stopped her by calming her down.

She becomes indebted to him and they grow closer to each other to the point where a relationship blossoms. Toward the end of the series, Aqua kisses her.

She learns of Aqua’s ambitions to avenge his mother a few months into their relationship and decides to help him in any way she can.

Akane is a mature woman who understands loneliness and can relate to others’ pain. Her caring and thoughtful nature makes her one of the most memorable characters in Oshi no Ko.

3rd on this list of the most popular Oshi no Ko characters, is Aquamarine, one of the twins birthed by Ai Hoshino. As a child, he watched his mother die from the attack of a stalker. This event deeply ingrained itself in him. He swore vengeance on the killer, and his whole life in the series is based on that.

It happens that he is a reincarnation of a doctor who took care of Ai Hoshino during her pregnancy. Since his memories from his previous life are intact, he uses the analytical mind he honed previously to go about uncovering the truth about his mother’s killer.

To this end, he develops a manipulative way about himself and starts seeing the world as a chess board, where with enough right moves, he will checkmate his mother’s killer.

He is not as single-minded as to forsake everything else in his life for this goal though. He happens to have a soft spot for his sister and people around him. This is shown through his support for Kana and his willingness to take action to save Akane’s life.

These traits plus his looks make him rank so high in the popularity ranks.

2. Hoshino, Ai (Main Oshi no Ko Character)

Taking second place is the one who introduces us to the complex themes of this story, Ai Hoshino. She came from a tough childhood, with her mother getting imprisoned for robbery, leaving her to fend for herself in an orphanage. Ai grows up love-deprived, doubting her very capacity to give or receive love. She was broken.

At a relatively young age, she gets into entertainment industry with the help of Saito Ichigo early on and makes it big despite the odds.

Her Breakthrough

Before she made it big, Ai was a troublemaker lacking professionalism and trying to fit in. Later on, she was able to join the Lalalie Theater Company with the aid of Kaburagi Masaya, and it was there that she fell in love with it and started to pay attention to herself.

Ai grows as a person throughout this journey and as an idol too, amassing a huge following. Over the course, she falls pregnant and decides to keep it, despite the rules that surround the type of work she does. She wanted to prove that she could love. Indeed, her past wounds were still fresh, and she needed to know if they still affected her.

Her company agreed to let her have the children (the twins) and helped her keep it under wraps, away from the media. She gave birth to two children and started to explore the nuances of love.

As she was starting to get the hang of it, she was murdered by a stalker for “betraying her admirers”. Her dying words and thoughts surprised her as she realized she did in fact, love her children so deeply, which made her happy and sad.

The tale of how she surmounted her deeply emotional scars and trauma to be a famous and loving mother resonates and inspires fans of the show to rank her up this high. She truly is awesome.

1. Arima, Kana (Supporting Oshi no Ko Character)

First place goes to Kana! We all love a good redemption story. Many of us are familiar with the abuse that originates from being called a childhood prodigy. You basked in that glory but as you grew older, it became difficult to achieve the same. The personality you obtained from the glory- lazy, and arrogant- makes it hard for you to get back your fame.

Kana Arima falls here, she used to be a talented actor as a child and grew arrogant. This made her lose many opportunities and face a drop.

Luckily, she realized where she stood, and how fickle her footings were, so she decided to change. Her attitude change, and her desire to be better, and to put in the work is why she stands at the top of this list. She was forced to adapt her acting style to maintain her place in the entertainment industry. Despite her challenges, Kana persisted in improving her skills, venturing into new avenues, such as singing.

After a heartwarming reunion between Aqua and Ruby, she was recruited for the B-Komachi group. After joining the group, Kana Arima regained her self-esteem, and her popularity increased drastically.

As a total tsundere, Kana 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, so it’s a race to see who will win.

She works hard to be the best version of herself.
