After her mom remarried, our main character Yuzuko Aihara transferred to a new school. She figured that she would get a boyfriend on the first day of school and dressed as stylish as possible and put on sexy makeup. As she belatedly discovers, however, the school she was transferring to is a strict, conservative all-girls highschool and she was almost immediately caught by the Student Council President for violating pretty much every single rule in the school book. Upon returning home from school, she realizes that with the re-marriage comes a new step-sister- Mei Aihara, the very student council president that gave her all the trouble earlier during the day. Later that night when Yuzu tries to passive-aggressively get back at her, Mei responds by stealing her first kiss......A Yuri dramedy manga by Saburouta, once published a bimonthly magazine called Yuri Hime now licensed by Seven Seas Entertainment, the series has two volumes out and is still ongoing.
Citrus contains examples of:
Absurdly Powerful Student Council: Justified since it is a conservative school with beliefs that the students should be able to police themselves. Not to mention the Student Council President's family owns the school and she herself will be the one who will eventually become the schools chairman later down the road.
Momokino Himeko for Mei, ever since she saw Yuzu dash out of the chairman's room, with Mei inside, she has been dead set on separating the two as much as possible. Of course, with them being step-sisters, it's a bit of a feat to accomplish.
Mizusawa Matsuri for Yuzu, an ex Girl Next Door who came to town solely to see Yuzu and confess her feeling towards her, after discovering her booth photo with Mei and Yuzu in a Held Gaze with each other, she challenged the notion of having a relationship with one's own step-sister. Later, after they walked out of the karaoke bar and spotted Mei outside of a grocery store, she grabbed Yuzu and gave her a kiss and Mei an icy glance, she established well enough that Yuzu was hers.
Eating the Eye Candy: Yuzu eats it whenever she and Mei are alone together, but special mention goes to when bathing together in chapter 2, Yuzu fantasizes about Mei's hair and skin and how soft she would be to touch. Mei eventually noticed her gaze...and advanced onto her and asked if she wanted to touch her as a tease.
Amemiya gave one to Mei in chapter one. Made more obvious in that when Mei pulled away from such kiss, Amemiya forced her back in again, only to be stopped when Mei spotted Yuzu spying on them in the bushes.
Mei herself could probably be the queen of this trope, giving Yuzu several unexpected and forceful kisses.
In chapter 4, Yuzu gave this back to Mei after Mei discovered her yuri incest manga and decided to give Yuzu a rather hypocritical lecture on how they are just sisters. Yuzu attacks and kisses her while tearfully voicing her intence confusion over her feelings towards Mei and what Mei's feelings are for her. This started Mei's defrosting process.
Girls Love: Even though there was a brief het scene in the beginning, it was of an ulterior motive and when Yuzu managed to dispel it, it is all about yuri pairings, mainly Yuzu and Mei.
Gold Digger: Amemiya was one, planning to marry Mei solely for high status and prestige. Fortunately, Yuzu managed to stop his plan by plainly stating that his forced kiss on Mei was an act of assault.
Happily Adopted: Neither Mei nor Yuzu are unhappy about their parents marriage. Their initial friction at becoming sisters is quickly resolved and replaced with trying to be good sisters while also dealing with their growing attraction to one another.
Heroic RROD: In chapter 6, Mei collapsed out of overworking herself on the student council work, much to Yuzu and Himeko's concern.
Played for laughs when Momokino exaggerated the trope when she saw Harumi feeding Yuzu her hot dog before Harumi commented that she took it too seriously and fed her a radish. Of course Yuzu's wondered how it would feel like when Mei does it instead of Harumi...
Averted in chapter 6 as Yuzu missed her chance to do it when she and Mei were eating crepes together. She gets the next best thing though.
In Chapter 10, Mei gives one to Matsuri, whom she saw kissing Yuzu before, and even tells her that she has taken back Yuzu's lips.
Important Haircut: Yuzu was going get one to signify that she needs to get over her love for Mei so that she can properly treat her like a sister in chapter 7, with the 'ceremony' performed by Harumi before being narrowly subverted by Mei who scolded them for trying to cut her hair in school.
Intertwined Fingers: Probably the biggest hint that Yuzu and Mei's kiss in chapter 8 is more then their normal UST.
Lower Deck Episode: The unnamed Meganekko that appeared in the beginning of the manga who only appear again near the end of chapter 2 to give a school speech was given 2 brief pages in Citrus Special issue 1 between her, Harumi and Himeko, giving a slightly playful observation to the two of them.
Luminescent Blush: Yuzu, whenever she was kissed by Mei, which showed her inexperience with love.
Meganekko: In chapter 1, a nameless student council member that initially stopped Yuzu for her school rules violation is this.
Moment Killer: In chapter 6, Himeko came up to Yuzu and Mei just as Yuzu was about to hold Mei's hands.
Ms. Exposition: In chapter one, Harumi acted as this to Yuzu, telling her, and the audience, everything about the school and why the students are so unwilling to even talk to Yuzu let alone hang out with her.
Not Blood Siblings: Mei and Yuzu are only related by their parent's marriage. It still weirded out Yuzu though. Initially.
Parents Walk In at the Worst Time: Mei's grandfather walks in on Mei and Yuzu having a heartwarming moment, unfortunately because Yuzu's top is undone exposing her bra and they are hugging on top of a bed, he jumps to conclusions.Note Admittedly, he wasn't far off the mark Unlike most examples this is very much Played for Drama.
Platonic Life Partners: Harumi and Yuzu became really good friends almost as soon as they met, and while both are open to lesbian relationships, they seem more than content to stay friends.
Posthumous Character: Yuzu's dad. While he is dead, Yuzu keeps him in spirit and does not mind his passing, as she was 3 at the time. Additionally, Yuzu used visiting him as an excuse to go on a 'date' with Mei.
Post-Kiss Catatonia: Yuzu's first kiss with Mei leaves Yuzu lying down wondering what happened, which Mei exploited as a good way of getting her to shut up.
After their real kiss in chapter 8 its Mei who pulls a Yuzu face
Schoolgirl Lesbians: Yuzu at first seems heterosexual and expected to get a boyfriend soon. As her relationship with Mei deepens, she embraces this trope. Himeko on the other hand plays this trope straight (no pun intended) albeit played for laughs after briefly discussing it.
Show Within a Show: Or in this case Yuri Manga Within A Yuri Manga. In chapter 4, Yuzu 'researches' her predicament by reading a Sister incest manga at a Manga Café.
"Shut Up" Kiss: Mei gave one to Yuzu near the end of chapter 1. In chapter 4, turns out Mei took this trope more literally, as it was the most effective way to shut Yuzu up and dismissed any meaning deeper than that, which pisses Yuzu off.
Sugar and Ice Personality: Mei puts up a very convincing facade when in public in order to keep up a good image for the school's reputation and her own personal agenda. When the situation calls for it, however, she can get pretty romantic with Yuzu...
Unusually Uninteresting Sight: Mei initially sees kissing as this, something she just does for no reason or meaning other than it being what people expect from her. Yuzu is no exception though it did have the bonus of shutting her up. Its not until she starts to have feelings for Yuzu that the kisses start meaning something, much to her shock.
Himeko. No matter how hard she tries to guilt trip Yuzu in chapter 5, Yuzu and Mei are still Not Blood Siblings and living in the same house, so naturally it would be exceptionally hard to keep them away from each other.
When You Coming Home, Dad?: Mei's dad was a perfect teacher and heir to the Academy—right up until he suddenly decided to leave his obligations behind and go on a world tour, leaving Mei torn apart between a desire to see him return and assume his rightful place and a need to become a suitable replacement.
