18 year old Miyashita Yukino always wanted to be on television. To accomplish this, when she was a teenager, she and a few friends formed an [[IdolSinger idol group]] together. Unfortunately things didn't work out as she and the group ended up splitting up. Yukino went back home but got fed up with people's hurtful words there concerning her former job as an idol. She decided in the end to return to Tokyo and is now working as an assistant manager for a modeling company. Yukino now lives alone and laments that she's never experienced love ...

... That is, until she meets a pretty woman by the name of Iwai Setsuko. After a while, Setsuko realizes Yukino's loneliness and Yukino learns about Setsuko's past which ends up with the two making love together. The day after, Yukino is left to sort out what happened and how she feels about Setsuko.

''Octave'' by Haru Akiyama is a {{yuri}} {{manga}} published by Kodansha. The manga is a mature and serious look at the genre.

----
!!''Octave'' contains examples of:

* AllMenArePerverts:
** Yukino's strongly-held belief, reinforced by a lot of bad experiences.
** Setsuko's brother Mari, as one of the few characters who never really mentions sex, averts this.
** Setsuko messes with the trope when she interrupts Yukino's AllMenArePerverts rant to point out that Yukino [[HypocriticalHumor got turned on by being watched in the bathhouse]], and then proceeds to have sex with her.
* CliffHanger: [[spoiler:Yukino sleeping with a male stranger at the end of volume two.]]
* ClingyJealousGirl: Yukino has severe trust issues in regards to Setsuko's friendships and past relationships, and the possibility Setsuko might someday leave her. Yukino's usually too passive to act on her fears, but they have some rough patches because of it. Largely abated towards the end of volume 3.
* ClosetKey: Setsuko.
* CovertPervert: While she would never admit it, Yukino is a little obsessed with sex.
* ADateWithRosiePalms:
** Yukino's sexual frustration seem to culminate towards moments like these. Even after she started dating Setsuko.
** It also appears that Setsuko seems to keep herself busy this way whenever Yukino isn't around.
* DesperatelyLookingForAPurposeInLife: A lot of Yukino's angst comes from the fact that since she already lived her dream, and because she failed it, she has no idea what she should do now, [[spoiler: by the end she begins to find purpose in being a manager for Idols and being with Setsuko.]]
* DoesNotLikeMen: Yukino initially, although she does get better.
* FuroScene: A few, actually. Especially since Setsuko's [[spoiler:new apartment]] has a bathtub.
* {{Gayngst}}:
** Yukino does quite a bit of this in volume two.
** [[spoiler:Shiori]] opens up a big ole can of angst when she gives her own little ComingOutStory to Yukino, revealing a messy breakup and future intentions.
* GoodPeopleHaveGoodSex: While fairly tame, ''Octave'' is rather explicit by comparison to most others.
* GreenEyedMonster:
** Yukino often shows a lot of jealousy towards idols, particularly her childhood friend Mika.
** Setsuko is bit of this herself, but under the pressure of not trying to scare Yukino out of their relationship because of possessiveness, she keeps that monster tamed - most of the time, at least.
* HalfIdenticalTwins: Setsuko and Mari.
* IJustWantToBeSpecial: Yukino is painfully obvious about this.
* IdiotBall: A lot of the drama derives from Setsuko and Yukino taking turns behaving like idiots toward each other.
* IdolSinger: Yukino, in the backstory, and Mika now.
* IfYouEverDoAnythingToHurtHer: Kamo-chan at the railway station. Friendship or something more? [[YuriGoggles You decide.]]
* IncompatibleOrientation
* InformedAttractiveness: Yukino. Big time.
* IntertwinedFingers
* LipstickLesbian: Setsuko, Yukino, and [[spoiler:Shiori]].
* NiceGuy: Mari first, and then Oozawa. Considering that Yukino DoesNotLikeMen, it's a good thing to have such unaffected, nice boys around for her to get over her disdain.
* NoPeriodsPeriod: {{Averted|Trope}}
* OldFashionedRowboatDate: Yukino and Setsuko go on one. Since they're both girls, they [[RockPaperScissors janken]] to decide who rows.
* OneHeadTaller: Setsuko to Yukino.
* PublicExposure: Yukino's friend Nao, from her old idol group, is now a porn actress.
* RomanticTwoGirlFriendship: Yukino had this with Kamo and Mika, but unlike most examples this seems to be used more as a confirmation of Yukino's orientation.
* SecretRelationship:
** Yukino and Setsuko.
*** [[spoiler:Actually, Yukino just ''thinks'' it's supposed to be a secret. Setsuko keeps their relationship low key, but she's not actively trying keep people from finding out. This misunderstanding leads to a little bit of drama (natch).]]
** [[spoiler:Shiori]] tries to convince Yukino to have one as well.
* SensitiveGuyAndManlyMan: Oozawa and Mari. Well, Mari may not be a total manly man, but he does walk around wearing shades, a wife-beater and isn't afraid to pee in public, so he's about the most testosterone-filled thing in the series.
* {{Sex as Rite-of-Passage}}: A female version.
* SexSells: A recurring theme is the in fiction example of this trope.
* SingleTargetSexuality: Shiori suggests that Yukino is this way to Setsuko.
* TomboyAndGirlyGirl: Not Setsuko and Yukino. This trope applies to Yukino's friend Kamota and Yukino.
* TransparentCloset:
** Yukino seems to be in one, considering that anyone with a pair of YuriGoggles seems to figure her out. Quite literally. It doesn't stop her from trying to claim that she's simply MistakenForGay.
** For the more goggle-inclined, there's Kamo-chan. An IfYouEverDoAnythingToHurtHer speech is a bit much for just friendship.
* TrueArtIsAngsty: InUniverse, Setsuko gains some praise for a song she composed during a rough patch of her relationship with Yukino.
* YuriGenre
