It has been decided that the anime "Oshi no Ko" will be made into an anime in April 2023, and the broadcast date is approaching! The two main characters who died a tragic death were reincarnated as their favorite idols! Starting from such a theme, "Oshi no Ko" is a work that is becoming increasingly popular due to its shocking developments that are unexpected from the theme. In this article, I would like to introduce in detail the main characters of "Oshi no Ko", Aqua and Ruby!

About the main character, Amemiya Goro, the previous life of Hoshino Aiku (Aqua)

Goro who dies

Aqua, the main character of this work, is a certain person who was reincarnated with his memories. In his previous life, he was a doctor named Amemiya Goro who worked at an obstetrics and gynecology clinic in the mountains of Miyazaki Prefecture. Due to a certain incident, Goro became a big fan of the idol group "B Komachi," and his favorite was Hoshino Ai, the center member of the group. However, he was shocked when Ai, his favorite, went on hiatus and came to the hospital where he worked pregnant. Nevertheless, as he got to know her better, he became even more of a fan, and supported her with all his might as she gave birth, but on the day of her birth, he was murdered by Ai's stalker.

A capable guy with a sharp mind and good communication skills

He was originally accepted into a national university as a doctor, so he is very smart, and as a former member of society, he also has excellent communication skills. He says he has no acting skills, but he is good at interpreting the intentions of directors and productions and acting accordingly. At that time, he was skilled in the way of surviving in the entertainment industry, but after a certain incident, he was deeply traumatized and stayed away from the world of acting.

In order to get revenge on her mother, she dives into the dark side of the entertainment world

Deciding to take revenge

The worst trauma that Aqua was instilled in her was the murder of her mother, Ai Hoshino, right in front of her eyes. This trauma made her unable to perform satisfactory acting, so she spent 10 years working behind the scenes at a film production company, Gotanda, learning the know-how behind the scenes. Aqua's obsession with the entertainment world is to take revenge on the person who is alleged to have been involved in Ai's murder. The murderer who directly killed Ai committed suicide after killing her, but the fact that there was an informant rather than someone in a position to know the address of the new house she had just moved into meant that the person with the motive and information was very likely to be a celebrity, Ai's boyfriend, and Aqua's father.

Aqua's obsession gradually brings him closer to the truth! ?

Aqua believes that the clue to the real culprit is in his genetic information, and that the person whose genetic information matches his is the culprit who led Ai to her murder. He brute-forces the password on Ai's smartphone, which was left behind, and takes on jobs he doesn't want to do in order to get closer to people who were related to Ai, and tries DNA testing on everyone who seems to be related, gradually getting closer to the truth with information, action, and obsession.

Is Aqua the best supporting actor? A man who is kind at heart and pays close attention to his surroundings!

Aqua who watches carefully

Aqua was calm and collected and intelligent when Ai was alive, but after Ai's death, he became cold-hearted. This was due to his determination to take revenge on Ai even if it meant risking his own life, but at heart he is kind and pays close attention to those around him. In his acting work, he purposely provokes the actors to bring out their best, sees through the mental state of his co-stars and prevents them from attempting suicide, does not take any noticeable actions in public but does great work behind the scenes, and is a character who brings out the best in the main characters by bringing out the best in those around him.

About the previous life of the other main character, Hoshino Rumii (Ruby), Tendouji Sarina

Memories of Sarina

A girl who was hospitalized at the hospital where Amemiya Goro works. She had a big influence on Goro, and was very attached to him. She spent most of her time since she was born in the hospital, and lived a hopeless life due to harsh rehabilitation and illness, but her only hope was the idol Hoshino Ai and Goro's presence. However, she died of an illness at the age of 12, four years before Ai gave birth. The cause of death was anaplastic astrocytoma.

Ruby is a nasty idol otaku! ?

Reincarnated troublesome otaku

Ruby was an enthusiastic Ai fan in her previous life, and even in her reincarnation, her passion did not change, and she became a troublesome otaku who repeatedly engaged in fierce battles with Ai's haters since she was a baby. She made the most of her natural rights as the child of her favorite idol and enjoyed herself to the fullest.

Ruby desperately wants to be an idol

Ruby loses the election

Ruby, who had always dreamed of becoming an idol since her previous life, continued to dream of becoming an idol in her new life and continued to attend auditions every day, but she was rejected again and again. In fact, Aqua was secretly suppressing the results so that Ruby would not become an idol. However, perhaps because there was something about her that attracted her, she was scouted by an underground idol in the city, and with the revival of Ichigo Production's idol business, she embarked on the path to becoming an idol.

The return of the new idol B Komachi!

B-Komachi Revival

Ruby, who inherited her parents' looks and charisma that attracts viewers, revived B-Komachi with the genius child actor Arima Kana, who can make you cry in 10 seconds, and YouTuber MEMcho, and their popularity took off. However, it was also true that there was a big wall to climb to stardom here.

Ruby and Goro, the worst reunion...

The worst reunion

One day, Ruby came to the hospital where she was born to shoot a music video. There, she discovered Goro, a skeleton, and was deeply shocked. When a mysterious girl appeared and told her that there were two culprits and that one of them was still alive, Ruby became determined to get revenge. However, for better or worse, those emotions had a huge impact on her own qualities as an idol. Her performance of those dark emotions shocked the industry, and B Komachi attracted a lot of attention.

【Oshi no Ko】Aqua and Ruby Summary

I've put together a summary of the two main characters of 【Oshi no Ko】, Aqua and Ruby! At first, the story progresses from Aqua's point of view, but in recent episodes, the story has been centered on Ruby. The story of how she rises to the top in the entertainment industry is fascinating, but the biggest mystery in 【Oshi no Ko】 - who is the mastermind who indirectly killed Ai and Goro, and who is the father of the two girls - is also a big highlight to see the mystery being solved from the two girls' point of view. Although it didn't have to be expressed in the manga, it has to be expressed in the anime, and there may be scenes where the mystery is solved meta-wise.
