History Manga / InTheHeartOfKunoichiTsubaki

* {{Iyashikei}}: The series places emphasis on SliceOfLife, focusing more on the interactions and dynamics between characters, as well as the "cute-girls-doing-cute-things" (CGDCT) story.

* NewTransferStudent: Rindou transfers from the Aoi Class to the Akane Class in Episode 6.

** '''Episode 6:''' "''Akane-gumi Katsudou Nisshi ~Tora-han~''"[[note]]Team Team Tiger[[/note]] by Mayu Minami (Fuki), Ayaka Nanase (Itadori), and Misaki Watada (Ume).

** Rindou starts going maskless a bit earlier in the anime than in the manga, due to the shuffling of chapters being adapted. In the manga, she wears her mask from Chapters 11-17. In the anime, Chapter 17 (the chapter she starts going maskless) is adapted before Chapters 15 and 16 - both chapters where she was depicted with her mask on, which the anime modifies to have Rindou maskless.

* ArtEvolution: The art progressively improves as the chapters go on, particularly with the characters outside of the main cast, as the first few chapters only have rough designs of them that either vaguely resemble their final designs or not at all. As more and more characters are introduced, the art becomes more refined to give each of them a stylized and distinct silhouette unique to one another.

** Chapters 25 and 26 introduce the Allure-Jutsu and Tsubaki's inability to perform it. It makes its return in Chapter 48 with Tsubaki finally managing to pull it off.

** Chapters 25-27 introduce the Allure-Jutsu and it quickly becoming widespread amongst the Akane Class.

** '''Episode 11:''' "''Akane-gumi Katsudou Nisshi ~Usagi-han~''" [[note]]Team Rabbit[[/note]] by Saya Aizawa (Kagetsu), Creator/AyasaIto (Mukuge), and Eri Yukimura (Hototogisu).

** "''Akane-gumi Katsudou Nisshi ~Usagi-han~''" [[note]]Team Rabbit[[/note]] by Saya Aizawa (Kagetsu), Creator/AyasaIto (Mukuge), and Eri Yukimura (Hototogisu).

* AdaptationalEarlyAppearance: In the manga, Team Rooster is the last team to be given a proper introduction, debuting in Chapter 41. In the anime, they are the eighth team to be introduced, appearing in Episode 9.

* ShowWithinAShow: In the ''Manga/TeasingMasterTakagiSan'' spinoff, ''Karakai Jōzu no (Moto) Takagi-san'', Chi gets ''way too hooked'' on a show about ninja girls, mimicking behaviors she sees, and it gets to the point where her parents have to step in before it gets out of hand. A Volume 6 omake for ''In The Heart of Kunoichi Tsubaki'' reveals that this is the very show that she's watching.

* EvolvingCredits: After her introduction in Episode 6, all subsequent episodes now include Rindou [[https://i.imgur.com/r2oNw2E.jpg to the title card in the opening]].

* DoItYourselfThemeTune: Coupled with EvolvingCredits. The ED, "Akane-gumi Katsudou Nisshi", is a series of ending songs, with a different iteration of the song being performed by a different team at the end of each episode:

* CastOfSnowflakes: Despite having a cast of a whopping ''thirty-eight'' characters right off the bat, each and every one of them
has their own unique design, ensuring no two characters are the same. Even Uikyou and Kikyou, who are almost exact mirrors of each other, do this with their [[ColorCodedCharacters color-scheme]] and legwear.

An anime adaptation directed by Takudai Kakuchi was announced on November 8, 2021 with production being handled by [[Creator/A1Pictures [=CloverWorks=]]]. The series was licensed by {{Website/Crunchyroll}} and it premiered on April 9, 2022.

* AdaptationalEarlyAppearance: In the manga, Team Rooster is the last team to be given a proper introduction, debuting in Chapter 41. In the anime, they are introduced in Episode 9. Not only does this rearrangement make their debut considerably early when taking into account what chapters have been adapted so far [[note]]Chapters 1-12, 15-19, and 23[[/note]], but the anime also makes them the eighth team to be introduced, coming before Teams Rat, Tiger, Rabbit, and Dragon, who were all introduced and given [[ADayInTheSpotlight spotlight chapters]] in the manga well before Team Rooster was [[note]]Team Rat is given focus in Chapter 14, Tiger in Chapter 20, Rabbit in Chapter 24, and Dragon in Chapter 34[[/note]].

* DoesNotLikeShoes: Both PlayedStraight and {{Inverted}}. In the character art, nine of the thirty-eight characters are wearing sandals while the rest either wear stirrups, bandages, or go barefoot. However, in the anime proper, most of these barefoot characters are shown to have opted for sandals, bringing the total to twenty-six, while the remaining twelve[[note]]Sazanka, Shion, Itadori, Higiri, Hasu, Uikyou, Hinagiku, Kibushi, Oniyuri, Benisumomo, Touwata and Shakuyaku[[/note]] continue to play this trope straight.

* OriginsEpisode: Episode 8 establishes how Team Dog and the other teams formed, as well as show the moment Tsubaki and Sazanka became friends.

* LeftHanging: Chapter 13 deals with Benisumomo growing suspicious of Tsubaki after a game of tag in Chapters 7 and 8 has the latter besting Hana while the former is easily defeated by her despite them being equals. Because of this, she suspects something more is going on with her, which ends up going unresolved. These suspicions are never brought up again after this chapter.
