History Manga / OshiNoKo

** ''Platform/YouTube'' is actually mentioned by name, but when images in the manga are shown it's called "Youlobe". The same goes to other platforms like ''[[Platform/TikTok TikTak]]'', ''[[Website/{{Google}} Gugule]]'', ''[[Website/InternetArchive Woyback Wochine]]'' or ''{{Website/Twit|ch}}''. The anime made the ProductPlacement straight with the brands listed below.

* TakeThatAudience: The series pulls no punches in showing that fans are as much, if not more, of a problem for the idol industry than the industry itself. That their impossible expectations place unreasonable burdens on the people they claim to love. That some fans become deluded into thinking the idols not as people with lives but their property to do with as they please.

* IAmSong: The anime adaptation's first opening song, "Idol" by Music/{{Yoasobi}}, describes Ai from the points of view of the media and fans (mysterious and perfect idol), her B-Komachi groupmates (jealousy yet respect of her for being the one member who put the group on the map) and herself (secretly a mother of two who wishes to be able to genuinely express love someday, as she has been pretending to all the time). It also summarizes the series premiere plot.

* IAmSong: The anime adaptation's first opening song, "Idol" by Music/{{Yoasobi}}, could have been performed by Ai herself and describes both her worldview and the series premiere plot.

''Oshi no Ko''[[note]]The common way to read it is "The girl (idol) I support", but it also can be read as "The children of the girl I support".[[/note]] (【推しの子】), also known as ''My Star'', is a collaborative work between Creator/AkaAkasaka, who serves as author, and Mengo Yokoyari (''Kimi wa Midara na Boku no Joou'', ''Manga/ScumsWish''), who serves as the artist. Since April 2020, it is published in Shueisha's ''[[Magazine/ShonenJump Weekly Young Jump]]''.

* MajorInjuryUnderreaction: [[spoiler: Ai after being fatally stabbed in the abdomen by her stalker. She first speaks with said stalker candidly about her hoping that her lies of love to her fans would eventually become true, until he flees the scene in remorse. She spends her last moments with Aqua and Ruby as lackadaisical as ever, declaring her love for them and [[GoOutWithASmile passing away soon after in a serene calm.]]]]

** ''Website/YouTube'' is actually mentioned by name, but when images in the manga are shown it's called "Youlobe". The same goes to other platforms like [=TikTak=], ''[[Website/{{Google}} Gugule]]'', ''[[Website/InternetArchive Woyback Wochine]]'' or ''{{Website/Twit|ch}}''. The anime made the ProductPlacement straight with the brands listed below.

** Social media sites Website/YouTube, Website/TikTok, and Website/{{Twitter}} are all out in the open within the story setting.

** One blink-and-you'll-miss-it detail during the Reality Show arc features a dig at Website/YouTube, more specifically, [=YouTubers=] that use video essays to haze people they don't like rather than actually spread information.

* NeverTrustATrailer: The [[https://www.youtube.com/watch?v=wAnrugOAoGE anime trailer]] makes it seem like a standard idol anime. This inevitably led to many manga readers commenting about how "wholesome" the anime will be.

* BreakUpMakeUpScenario: The relationship journey between The Hoshino Twins [[spoiler:starts off from their past lives as Goro Amamiya and Sarina Tendouji. The two grew close with each other as an intern physician supporting a bedridden cancer patient. They were special to each other, and affected each other in ways that affected them even in their next lives. Their souls then part ways as Sarina lost her fight to cancer, and Goro was murdered by his Ai's stalker. The two then reincarnated as twin siblings born to Ai as their mother. As the two lived a new life together, their identities were a topic that they avoided. After Aqua had revealed their shared parentage to the world, their relationship fractured shortly after, with Ruby not wanting anything to do with Aqua after the fact and Aqua trying to make Ruby hate him due to wanting her to live without him. But during the events of Chapter 123, with the reveal of their mutual identities to each other, they eventually reconciled and repaired their relationship, growing closer as a result.]]

** Upon reincarnating, Aqua has a hard time seperating his feelings for Ai as a fan in his previous life, and his feelings towards her as his mother in his current life. [[spoiler:Ruby encounters the same issue when she finally learns that her crush as Sarina reincarnated as her twin brother as Ruby. Unlike Aqua, Ruby [[{{Twincest}} gives a decisive answer to this conundrum]]; [[LoopholeAbuse having ideas how it could still work]].]]

* BreakUpMakeUpScenario: The relationship journey between The Hoshino Twins [[spoiler:starts off from their past lives as Goro Amamiya and Sarina Tendouji. The two grew close with each other as an intern physician supporting a bedridden cancer patient. Their souls then part ways as Sarina lost her fight to cancer, and Goro, while lived on for four more years, was murdered by his idol's stalker. The two reincarnates as twin siblings born to their idol as their mother. As the two relives a new life together, neither of them knew the identities of the other's past life, but they got along fairly well, and supports each other throughout the loss of their mother. Then their values part ways based on different priorities, but they eventually consolidated after Aqua confirmed Ruby's past life identity to be of Sarina, and took the initiative to come clean to Ruby as so the two of them can enter their state of healing]].

** In Chapter 23, Ruby gets jealous because Aqua gets to eat out with beautiful young celebrities. Aqua denies it, but Ruby can easily see through his lie because he can't look her in the eye and his face clearly shows his satisfaction. Though it may look as if Aqua is denying his enjoyment of being surrounded with celebrities in Ruby’s eyes, Aqua, in “Goro’s” POV, was actually attempting to hide his appreciation for his new body’s fast metabolism.

** Ruby called Aqua a "brocon" to Kana's face, which he seemed to have accepted as he did not correct Ruby on that fact. Not to mention Ruby acting like a ClingyJealousGirl after Aqua spent his weekend with the LoveNow cast members instead of eating with her as per their previous routine. Her reaction upon seeing Aqua kissing Akane is also strange, saying that "it was five times as awkward as seeing siblings kiss on TV". The implication of seeing her brother kissing a girl being more stomach-churning than seeing two siblings kiss is obvious. And again during the Tokyo Blade arc, when Minami suggests that Aqua and Akane are having intercourse, Ruby reacts especially out of character at the prospect of Aqua getting a high school girl pregnant. And immediately after reaffirming her faith in Aqua, she quickly finds a restroom to presumably collect herself, as Minami was able sense Ruby's distress at the prospect. Even at the end of the arc, after Aqua had returned from his conversation with Himekawa, Ruby slept on the couch in order to sense when Aqua had returned home. Not quite behaviors that a typical sibling would perform, reincarnated or not.

''Oshi no Ko''[[note]]The common way to read it is "The girl (idol) I support", but it also can be read as "The children of the girl I support".[[/note]] (【推しの子】), also known as ''My Star'', is a collaborative work between Creator/AkaAkasaka, who serves as author, and Mengo Yokoyari (''Kimi wa Midara na Boku no Joou'', ''Manga/ScumsWish''), who serves as the artist. Since April 2020, it is published in Shueisha's ''[[Magazine/ShonenJump Weekly Young Jump]]''.

** The twins' suspected biological father's full name was foreshadowed as early as Chapter 12, when [[spoiler:Aqua borrows the name of a staff member from his agency, "''Hikaru Kanzaki''" to pose as a recruitment agent of Strawberry Productions. While their suspect's name, Hikaru Kamiki, is entirely written in katakana in the original Japanese release, one of the possible ways to write the first character in his surname "Kami" in kanji is "神", which is one of the characters used to write the "Kan" in "Kanzaki"]].

* InconsistentSpelling: Goro's surname 雨宮 can both be read as A'''me'''miya and A'''ma'''miya. The text in Chapter 75 says his name is to be pronounced Amemiya, but in Chapter 78 it's Amamiya. The translation team working for MANGA Plus eventually contacted Shueisha, who confirmed that the pronunciation is supposed to be Amamiya.

* InstantHumiliationJustAddYouTube: In Chapter 4, Aqua and Ruby embarrass themselves as babies as they get caught performing glow stick dances to cheer on their mother who reacts with delight. While this act was already embarrassing enough to the twins on a personal level, a spectator recorded the full event and upload clips to social media, which Miyako ends up getting scold by Ichigo.

** Chapter 77 has [[spoiler:Ruby and Akane find a dead body hidden in a cave behind a shrine when they return to the place where she and Aqua were born. And because of the ID and sticker still being on it, Ruby recognizes it as Goro.]]

* TaughtByTelevision: Subverted. Aqua explains his TroublingUnchildlikeBehavior by claiming that he learned all of this by watching [=YouTube=].

** Akane Kurosawa attempts to be more aggressive to stand out in the show ''My Love With a Star Begins Now'', which leads to her accidentally cutting Yuki's cheek with her fingernail. She immediately regrets it.
