Hanjuku-Joshi

Hanjuku Joshi begins with the readers being introduced to first year highschool student Yae, who is naturally and intuitively feminine, something she despises in herself. We're then introduced to her classmate Chitose, a naturally tomboyish girl whom Yae is both admiring and jealous of.

Chitose quickly sets her sights on Yae and tries to become close to Yae, even on occasion flirting with her. Chitose eventually wins Yae over and the two become close friends. However, their Unresolved Sexual Tension continues to build and build before finally culminating in a kiss... Both of them are confused by this. What happens next for the pair? Is the love between them real?

Hanjuku Joshi is an explicit Girls Love Manga by Akiko Morishima (Creator) originally debuting in Yuri Hime Wildrose. The erotic fare is there in the Manga though it's used to analyze the relationships of the members involved. This work is also notable for comparing and contrasting legitimate romantic relationships between girls to the more typical to the Japanese mindset, Class S style relationships.

Hanjuku Joshi provides examples of:

 * A Cup Angst: Chitose, not as angry about her lack of endowments as some examples but she often comments on being jealous of Yae's bust.
 * Beta Couple:
 * Bifauxnen: Chitose
 * Big Breasts, Big Deal: Yae is a Type 2. She even wears an uncomfortably small bra in a fruitless attempt to cover them up.

 * Caught With Your Pants Down: Yae and Chitose walk in on  having sex in the library.
 * Yae and Chitose themselves fall victim later on, when Ran bursts in on them after hearing strange sounds in their dorm room. She chides them for leaving the door unlocked.
 * Christmas Cake: Ran angsts about this in a later chapter.
 * Class Representative: Chitose and Yae although with personalities not stereotypical of this trope.
 * Closet Key:
 * Closeup On Head:
 * Mari and Ran are discussing Yae and Chitose. The camera zooms out, revealing that.
 * Mari is holding an English study guide, and Yae is tearfully telling her about her fight with Chitose....in a bubble bath. Together. Yae isn't sure how this happened.
 * Contrived Coincidence: Two different First Loves show up moments after someone mentions them.
 * Elevator School
 * Even the Girls Want Her: Chitose
 * First-Name Basis: Chitose encourages Yae to call her by her given rather than her family name.

 * New Old Flame: Yae's junior high friend and unrequited crush Youko, who pops into the story to unwittingly stir up old angst.
 * No Nudity Taboo: Chitose undresses in front of her class on the second page. Her entire family is equally blase about being half-naked, at least around each other.
 * Yae's influence eventually makes Chitose herself (a little) more self-conscious, to the shock of her classmates.
 * No Periods, Period: Averted twice. Chitose and Yae each have a plot-relevant period during the series.
 * One-Gender School:
 * Perpetual Molt: Seen on the chapter openings.
 * Please Put Some Clothes On: Yae saying this to Chitose becomes a Running Gag.
 * Rape Is Love: Subverted as the scenes never involve rape even if it sometimes looks like the Manga might be going there.
 * Chitose pushes Yae into a bathroom stall, orders her to take off her shirt and gropes her...because she was concerned her bra didn't fit. (Chitose figured Yae would've refused if she'd just, you know, asked.)
 * Chitose does force herself on Yae on one occasion, but stops as soon as she realizes Yae really does mean "No".
 * On the other hand,
 * Really Gets Around: Mari, though it's revealed that her promiscuity stems from

 * Secret Relationship
 * Seme and Uke: Played with, lampshaded, but ultimately subverted.
 * Sex As Rite of Passage: The "sex equals adulthood" aspect of this trope gets discussed and ultimately subverted. Mari tries to deliberately invoke it, thinking that having sex with boys would "make her a woman," but isn't pleased with the results. Yae also lampshades and subverts it after her and Chitose's first time: "I thought if I did Ecchi things, I'd become an adult. But it seems I've somehow returned to being a child."
