Secret Keeper / Anime & Manga

Secret-Keepers of Anime and Manga.

---

• Ajin:
  • Tosaki knows that Izumi is an Ajin, but is pulling strings to prevent her from being used for experiments. However, he's not doing this out of kindness, but is using her for his own purposes.
  • The elderly woman who temporarily shelters Kei knows his true identity as an Ajin on the run, but tries to pass him off as her grandson.
• AKB49 – Renai Kinshi Jourei:
  • Minoru suspects that Maeda is aware of his true gender, but has never outright asked her to confirm his fear. Maeda confirms it herself when Minori collapses and later wakes up with Maeda by "her" side, taking care of "her".
  • Miss Aphrodite is also aware of Minori's true gender, and takes "her" under her wing prior to "her" graduation.
  • At the very end of the series, all 250 AKB fans who attended Minori's graduation concert become this for Minoru, having watched his farewell confessional and convinced to keep the memory and good will of Minori alive out of respect. Not a word gets out to tabloids (thanks to Miss Aphrodite and Raoul's help) or on the Internet, at least from what we see of the four months after Minori's graduation.
• In Baccano!, Ronnie Schiatto serves as Maiza's secret keeper and only constant companion up until everyone in the Martillo family winds up immortal, and Maiza catches on that that Ronnie is a lot less human than he originally presented himself as, at which point the roles reverse.
• In Bakuman。, Moritaka Mashiro, after finding out that his fiancee Miho Azuki's mother Miyuki once loved his uncle, Nobuhiro, and that Miho is unaware of this, asks Miyuki not to tell her. She agrees and asks Moritaka's partner Takagi to do the same. This comes back to haunt Moritaka later, as Miho becomes angry with him for keeping it from her, and does not believe they should have secrets between them.
• Bleach:
  • Both Isshin and Karin are aware of Ichigo's activities as a shinigami, but don't let on. Isshin later reveals his knowledge to his son.
  • Tatsuki, Keigo, Mizuiro and Chizuru are also aware that something is happening but tell nobody outside their circle. Eventually, Ichigo admits everything to them.
  • Kon became a reluctant secret keeper for Isshin. He found out hundreds of chapters before Ichigo that Isshin was a shinigami, but Urahara and Isshin both swore him to secrecy.
  • Yumichika, Renji, Keigo, Komamura, Iba, Akon, Mayuri and Ichigo are all secret-keepers for Ikkaku's bankai. Mayuri's a subversion: he accidentally told Ichigo before remembering it's a secret, and doesn't care he revealed it. Ikkaku doesn't know Ichigo knows.
  • Hisagi is the sole living person who knows the truth about Yumichika's abilities. Specifically, Yumichika's shikai is actually a kido-type that drains spiritual pressure, something that he keeps secret so as to fit in with the combat-oriented eleventh division.
  • The Ishida family is such an unknown to the Vandenreich that Yhwach used Exact Words to lie with the truth, ensuring the Stern Ritter learned only of Uryuu Ishida's existence. While it's implied Haschwalth knows about the family, it's confirmed that Quilge Opie definitely knew all about Souken and Uryuu Ishida, and the mysterious Ishida family secret.
• Bloom Into You:
  • Near the start of the series, Yuu learns the truth about Touko- that she's far more emotionally vulnerable than she lets on, and had to work hard to become the highly respected honor student and Student Council President of the school. Unbeknownst to Touko, her best friend Sayaka also knows this, but after Touko learns that her sister may not have been the person she thought she was, Sayaka starts openly talking with Touko about Touko's sister.
  • Sayaka also knows that Riko Hakozaki, a teacher at her school, and Miyako Kodama, the owner of a local cafe, are a lesbian couple.
  • Maki happens to witness Touko kissing Yuu, but keeps it secret on Yuu's request.
  • Yuu's sister Rei is one of the first to realize that Yuu and Touko have feelings for each other, and supports their relationship. In the final chapter, both she and Yuu's friend Natsuki know that Yuu and Touko are dating.
• In Boarding School Juliet the forbidden romance between the two leads is only known to their respective Childhood Friends Char and Hasuki, joined by Inuzuka's brother Airu and mother Chiwa later on, with the last one who shows her full support. Inuzuka's rival, Maru, knows "Julio" is a girl and keeps it a secret to her request, but doesn't know her identity until Leon exposes the couple to the entire school in Chapter 85.
• At the start of Boku Girl, Mizuki's best friend Takeru is the only person who knows he's been Gender Bent into a girl. Later, Takeru's sister Mei is brought in on the full secret. Mizuki's roommate Yamada knows Mizuki is physically female, but thinks he's a girl masquerading as a boy. As far as Mizuki knows, the same is true of classmate Loki, though in that case Loki is the cause of the Gender Bender. As of Chapter 38, Mizuki's crush Fujiwara has also been told the full truth.
• Tamura and Ryousuke from Bokura no Hentai crossdress for various reasons. Ryousuke threatens Marika's life in the second chapter for her to keep his secret. Later in the manga Ryousuke's secret becomes known to his girlfriend, who asks him why he does it. This leads to his mother getting sent for mental health treatment, as his reason for crossdressing is because he's pretending to be his deceased sister for her.
• Captain Tsubasa:
  • In the anime version of the junior high arc, Sanae becomes Takeshi and later Hyuuga's secret keeper in regards to Hyuuga being benched by his coach, rather than injured or ill. This is because the first directly told her in hopes to have her talk to Tsubasa so he'd intervene (but she refused, since she saw it as something Tsubasa shouldn't be concerned about, and Takeshi apologized for potentially putting her in a very awkward position); later Sanae and Hyuuga bump into each other and she tells him what happened with Takeshi, Hyuuga takes it well and neither says anything to others.
  • Tsubasa becomes this in the Shin manga and OAV's, when Wakabayashi tells him that his unexpected harshness towards the Japanese team in the mini-tournament they're in is a mix of Tough Love and pretending to be a jerk. Tsubasa promises to not say anything and keeps his word until Hyuuga, who had become a Secret Secret-Keeper, reveals the deal before the final match.
• Tomoyo Daidouji, Syaoran Li, Meiling Li, Toya Kinomoto, Kaho Mizuki, and eventually Yukito Tsukishiro for Cardcaptor Sakura.
• Case Closed:
  • The trope gets invoked in a nasty manner in a filler case. A girl named Shouko Utakura finds her friend Sawanami dead and, due to his dying clues, she realises that their common acquaintance Mifune is the murderer. However, Shouko is Mifune's Unrequited Tragic Maiden and decides to keep this a secret... but commits the huge mistake of actually telling Mifune that she knew the truth, but wouldn't snitch. Mifune, who had killed Sawanami because he was involved in his girlfriend's death and now believes Shouko had something to do with it too, thinks she'll denounce him anyway and a few days later he strangles her to death, having a breakdown when he's uncovered as the killer and another woman explains Shouko's true feelings.
  • It's strongly implied that Rei aka Tooru Amuro is on his way to learn Conan's secret identity. At the very least he already knows that Conan is behind Kogoro's success.

• In Classi9, Mozart is the only one to officially know about Rentarou's true gender, and if anyone finds out, he will be expelled with Ren.
• Code Geass:
  • Since C.C. gave Lelouch his Geass and later installed herself in his bedroom, she is a Secret Keeper (and sometimes Body Double) for him and him Zero activities.
  • Lelouch gains many more Secret Keepers as the second season progresses with the likes of Kallen and his own maid, Sayoko, but after the Grand Finale, only a handful of people in the world know that Zero has been replaced by Suzaku Kururugi (including Kallen, Nunnally, and probably others like Ohgi, Kaguya and the rest of the highranked Black Knights) .
  • On another level, Milly Ashford and Suzaku Kururugi are the only ones of Lelouch's friends who are aware of his and Nunally's royal heritage, since the former's family are the ones sheltering them and the latter lived with them during their initial exile.
• Crossplay Love: Otaku x Punk: Shimazaki figures out on his own that "Hana" is his friend Hanae, and keeps his secret safe.
• Misa, Mikami and Takada all knew Light's secret at some point and helped him in his schemes in Death Note. Ryuk and Rem knew it too, but as invisible shinigami, most of the time they weren't even able to tell anyone if they wanted to.
• Destroy All Humankind. They Can't Be Regenerated.: Emi is desperate to keep her Magic: The Gathering pastime a secret from both her overbearing mother and everyone at her school, fearing that it would ruin the reputation she built up for herself over the years. While Hajime thinks it would be better off if she just acts like herself, he understands her situation and helps hide her hobby from the rest of the cast.
• Kazumi and Tatsuya in Devilman Lady are the only ones who know that Jun is becoming a demon.
• Don't Meddle with My Daughter!: At the end of "Honey, Hold me Tightly!", a flashback shows Mei has known about Clara's secret identity as the Eighth Wonder, from the beginning. Clara had received a call sign on her smartphone and ran out of class, so Mei followed her into the hallway, where she saw her changing into her costume. From then on, Mei kept her safe by not telling anyone.
• The Elusive Samurai: As Tokiyuki's closest allies, Yorishige and the Elusive Warriors are among the only ones among the resistance to know of his true identity as the surviving heir of the Hojo royal family before he publicly reveals it in Chapter 70.
• Sena's title Eyeshield 21 is kept by Hiruma, Kurita, Panther, Shin, the Ha-Ha Bros.
• Fruits Basket:
  • The whole premise is Tohru Honda serving as the Secret Keeper of the Sohma family if she wants to continue living with them, leaving even her two closest friends out of the loop — even though one of them has Electric Psychic Powers. She's also the only one of the teenage cast members let in on Kureno no longer being cursed and Akito being female.
  • Hiro was the only other witness to Rin being shoved out a window by Akito until he tells one of the other Zodiac members near the end of the story.

• In Genshiken it is implied that Ohno knows about Madarame's crush on Saki, as she tries to covertly give him pictures of Saki in cosplay outfits.

• Hajiotsu has Otogi reveal to Shuuko that he's aware that the whole relationship of Himari and Kai is based off of a test of courage. When she begs him to not tell Kai, that Himari should be the one to tell him, Otogi goes with it.
• Despite being in mysterious competition with one another, the members of the SOS-dan in Haruhi Suzumiya, besides Haruhi herself, fiercely guard each other's secret origins.
• In the anime/manga version of The Heroic Legend of Arslan:
  • Daryun's uncle Vahriz was one of the very few people who knew that Arslan is adopted and is not actually Andragoras and Tahamine's biological son.
  • Andragoras knows something pertaining to the truth of the history of Pars' royal family which is strongly implied to be the reason why he seemingly murdered his brother and tried to kill his nephew as well. He reveals some details to Sam that his father Gotarzes II was a very superstitious man and received a prophecy that royal line will end with his child. Despite fathering two sons, Gotarzes remained deeply fearful. Then, he was told a counter-prophecy that if a child was born to the wife of his oldest son, the line will continue beyond his sons. Sam believes that makes Hilmes said chosen child, but Andragoras reveals more details, that the reader is unable to hear, but leaves Sam shaken. Andragoras even tells Sam to take the information carefully as he points out that Andrgoras could be lying or being deceived himself.
• Hime-chan's Ribbon has Daichi become the secret keeper for Hime-chan about her ability to magically transform after she had to do it in front of him to save somebody.
• Mido of I Think I Turned My Childhood Friend Into a Girl wants to keep his makeup hobby a secret from everyone, save for the one he actively applies makeup to. Eventually, others find out about it, but they agree to not tell anyone else.

• Inuyasha:
  • Kagome's mother, brother and grandfather keep Kagome's time-traveling a secret. This leaves Souta to pick up the slack for Kagome at school (ensuring she knows when exams are and what homework she needs to do) and her grandfather creating hilarious and embarrassing medical conditions to both excuse her from school and prevent her friends from visiting her.
  • Toutousai. Although it was obvious he knew the truth about Tessaiga what had been hidden much better were the secrets he was keeping about Tenseiga and Bakusaiga.
• Kaguya-sama: Love Is War:
  • Fujiwara is a reluctant one for Shirogane concerning his lack of athletic coordination, non-existent dancing skills, and inability to sing. As she knows that Shirogane has an image to uphold, she cannot bring herself not to help him both out of pity and her own self-respect, which always come at a great toll for her because he's an awful, awful learner. In fact, Fujiwara's ability to keep a secret is probably one of her greatest strengths and the entire reason why she is Kaguya's Only Friend at the start of the series.
  • The truth behind Ishigami's suspension in middle school is kept a secret for the most part out of respect for him wanting to keep Otomo from finding out the truth, though them members of the student council (sans Miko) know the truth and informed the various club leaders in order to insure that Ogino would face justice for his actions.
  • Hayasaka's status as Kaguya's personal valet is supposed to be a secret from their classmates, hence why they rarely spend time together during school hours. The only student who knew the true nature of their relationship prior to Hayasaka quitting was Kaguya's cousin Maki.
  • The only students know the identity of the balloon thief are Kaguya, Hayasaka, and Momo.
  • There is an ever growing list of people who know about Kaguya and Shirogane's Secret Relationship. In order: Hayasaka, Shirogane's father, Kashiwagi, Maki, Kei, Onodera, Miko, Tsubasa, and Mikado (and that's not even including the various Secret Secret-Keepers). Hayasaka's role as such is extra significant since she's under strict orders to report everything about Kaguya to the main house and yet she still managed to keep that one thing a secret.
• Kaiju Girl Caramelise: When Kuroe Akaishi starts transforming into Harugon, only her mother Rinko knows that she and the monster are one and the same. Downplayed with Koutarou Hibino, who knows about the Involuntary Shapeshifting she has been subject to since childhood but not that she is Harugon.

• In Karin, Kenta Usui ends up strong-armed into becoming one for the Marker family when he learns that their middle daughter Karin is a vampire.
• In the classic anime Kimagure Orange Road, blood members of the Kasuga family all had psychic powers and a desire to keep them a secret from the general populace. This necessitates that anyone who marries into the family (such as Kyousuke's father) must become a Secret Keeper. The manga takes this to its logical conclusion that members of the Kasuga clan must reveal their powers to those they intend to marry before they can get hitched. Hopefully, if you love them enough to marry them, they like you enough not to blab your secret to the world.
  • The other major secret that Kyousuke has — his budding love for Ayukawa Madoka — is kept by his sister Manami. In the manga, she even explains it to Hikaru, with the iconic "red hat" as proof.
  • The Master of the local coffee shop, Abcb, knows the feelings that both Kyousuke and Madoka have for each other.
• In Kuttsukiboshi, Aya is this to her friend Kiiko's telekinetic powers. Well, besides being her lover.
• Land of the Lustrous: Padparadscha knows about Sensei's secret relationship with the Moon People. Unfortunately for Phos, the gem falls asleep before revealing any relevant information.
• Subverted with Hayate in Magical Girl Lyrical Nanoha A's. She was fully aware of the Wolkenritter's identities, but they deliberately kept their actions a secret from her since they knew she wouldn't approve.
  • At the end of the season, there's Arisa, Suzaka, and Nanoha's family discovering Nanoha and Fate's secret as Magical Girl Warriors. Reflection reveals that Arisa and Suzuka's parents are also in on the existence of magic (within the movie continuity, anyways). Whether or not Suzuka's older sister Shinobu knows is unspecified, though she probably does.
  • Episode 18 of StrikerS revealed that Teana already knew about Subaru and Ginga's status as combat cyborgs.

• There are four Muggles in Miss Kobayashi's Dragon Maid who are aware of the existence of dragons: Kobayashi, Takiya, Shouta's mother, and Chloe. The first two have Monster Roommates, the third is in a Muggle–Mage Romance, and the fourth found out when Kanna rescued her from a kidnapping.
• Athrun Zala in Mobile Suit Gundam SEED Destiny is a Secret Keeper for Meer Campbell, the Body Double standing in for his ex-girlfriend Lacus Clyne.

• The existence of mononoke in Mononoke Sharing is supposed to be a secret to the general populace, at least until the ongoing social experiment on whether or not To Unmasque the World is completed. Individual mononoke or their human roommates can issue a formal request to reveal themselves to friends or loved ones, but the potential secret keeper needs to prove themselves to be trustworthy beforehand (performing these tests is actually one of Chiehime's duties).
• Musuko ga Kawaikute Shikataganai Mazoku no Hahaoya: When Gospel's pediatrician Veronica calls to report that recent bloodwork done on him suggests his antibodies against anti-demon weapons are unusually high, it prompts some panic among Lorem, Merii, and Chiharu, as one of the main reasons the identity of Gospel's father is kept quiet is because as the demon whose poison anti-demon weapons are made from, Gospel has a potential resistance or immunity to them. This has potential to cause problems as the humanity's possesion of anti-demon weapons is the main thing keeping the peace between the two races. When it becomes clear they can't just dodge Veronica's requests for a re-test to confirm, they take her into their confidence and she agrees to keep things quiet for them.
• My Hero Academia has the secret of Izuku Midoriya's (and by extension All Might's) Quirk "One For All". Only the other U.A. hero teachers and Naomasa Tsukauchi (All Might's Commissioner Gordon, who found out by accident) knew that All Might turns scrawny when his power runs out before his fight with All For One, and only All For One (All Might's Arch-Nemesis), Gran Torino (All Might's mentor), Sir Nighteye (All Might's former sidekick), Recovery Girl (the U.A. High School nurse), Principal Nezu, and most recently Katsuki Bakugo know One For All is passed down from person to person.

• The characters who know that Kiri is the male model, Tatsuki, in Never Give Up are her mother, Tohya, and her best friend, Natsu.
• One Piece:
  • A case shows up regarding what really happened between Zoro and Kuma. Aside from Zoro himself, only three members of the crew know the truth: Brook, who saw it happen (since it's next to impossible to tell if a skeleton is conscious or not); Sanji, who heard it from the Risky Brothers and told them not to tell anyone else; and Robin, who used her powers to eavesdrop on that conversation. And Zoro only knows that Brook knows; the other two keep the knowledge to themselves because it would devastate Luffy if he found out, and Zoro didn't do it to be praised anyway.
  • The Gorgon Sisters would sooner die than let anyone find out that they were ever slaves to the World Nobles; only four known individuals have been trusted with the secret. The first three are Silvers Rayleigh, Shakky, and their surrogate mother Elder Nyon, who helped them get back to Amazon Lily after they escaped. And the fourth is Luffy, Hancock's love interest.
• In One-Punch Man, Saitama tells Suiryu to keep his secret of lying about his identity and impersonating Charanko.
• In Ouran High School Host Club, the whole Host Club keeps Haruhi's real gender a secret since she's working as a Host to pay back her debt.
• In The Pet Girl of Sakurasou, Sorata is asked to keep one from Misaki regarding Jin. He finds out Jin wants to go to a university in Osaka, not a local one nearby where Misaki was going. Jin says he's going to tell her at some point, and asks him not to tell her about it. Then Misaki finds out about it anyway in episode 11, although it was Fuuka, Misaki's sister, casually mentioning it to Jin, who says she heard it from his mother. Although Sorata comes clean about knowing the secret, Misaki seems more excited by the fact that he turned down her sister, which mean she still has a shot with him.
• Pretty Cure:
  • Fresh Pretty Cure! has Kaoru, Miyuki, and later in Episode 45, the Cure's parents and friends.
  • Heart Catch Pretty Cure has Tsubomi's grandmother, Kaoruko. It also helps that she was a former Cure herself.
  • The Pretty Cure All Stars movies reveal that each of the teams know of each other's identities. Except for the new team, which quickly becomes moot after awhile.
  • In Doki Doki! PreCure, it would seem that Sebastian is the only human who would know the Cures' true identities. That is until in Episode 41 that Alice's friend/rival, Reina, becomes one. If that wasn't enough, the Cures' family and friends get the chance to find out when Cure Heart ends up revealing who she is.
• Fakir becomes this for Ahiru in Princess Tutu when he discovers she's the titular Magical Girl. She later also tells him that she's really a duck that can transform into a girl.

Tomoomi Hanamura, the Intrepid Reporter Hiroki Matsumae, fellow aspiring actress and illegitimate child Mariko Soriarno and her Evil Counterpart Kana Juumonji/Satoka Ryoudou.
• The Tendo family, Ryoga, Shampoo and her grandmother, Mousse, Ukyo, Konatsu, and Nodoka in Ranma ½. This is only in the anime — in the manga, it's easier to list those who don't know Ranma's "secret".
• A handful of one off characters in the Sailor Moon anime find out about one or more of the Sailor Senshi's identities, but they usually only show up in an episode each. The manga has a few more recurring characters learn of the masquerade (most notably Motoki). It is implied in both R/the Black Moon arcs that Naru does know Usagi is part of something unusual and important but is aware Usagi doesn't want her to ask about it, so Naru complies and doesn't pressure Usagi about it.
• In Sakura Quest, Chitose Oribe is the only person Akiyama has told about a past incident in which Akiyama rented out his store to an outsider, and served as the guarantor on the loan, only for the outsider to skip town. Chitose remains quiet about this for years until several other local merchants try to pressure Akiyama into renting out his store to Belem, at which point she tells them about the secret, which explains why he'd be's reluctant to rent his store to anyone else.
• In Sekirei, a majority of the Single Numbers (with the exceptions of Tsukiumi and Akitsu), as well as Uzume, Seo, and the twins Hikari and Hibiki, are sworn to secrecy about the identity of the mysterious #01. It is Harem Nanny Miya Asama. The secret is kept primarily because they are terrified of what she will do to them if they let it slip. Even the Big Bad honors the secret, and leaves her alone.

The gang agree to keep the identity their secret, though Lovelitchi does reveal it to the public later on.
• In Tomica Hyper Rescue Drive Head Kidou Kyuukyuu Keisatsu, Jin knows the true face of the masked idol, Sala Manda. Inversely it's hinted that she may have realized that he's the driver of White Crystal Hope, given that she thanks him by name.
  • Kumiko Kurumada, Gou's mother, is aware of the identities of the drivers. She seems to be the only person outside of the Mobile Rescue Police who definitely knows the truth. Until the movie, when Karigari and his subordinates discover that Gou is the driver of Cyclone Interceptor.
  • In the multi-month period between the end of the series and movie Sasagawa is the only one who knows that Karigari is still alive (aside from his subordinates, who were with him the whole time).
• Tonari no Kashiwagi-san: Yuuto finds out about Kotone secretly being an otaku, which is what kicks off the plot. Sayaka, a Childhood Friend of Kotone, was already in the loop, and eventually more characters find out. Tina figures it out herself almost immediately when she notices the phone strap Kotone has, and Yuuto tells her to keep it a secret.
• In the start of Wandering Son only Takatsuki and Nitori know each other are transgender. Over the span more of their friends begin learning and eventually both just out themselves in middle school when Takatsuki begins wearing the boy's uniform to school and Nitori tries (and fails) to wear a female uniform to school.
