Hana no Kishi

""I swore it to my brother. I will find the person who attacked Sei-sama and killed my brother without fail, and punish him. And... And then more importantly... I will continue... protecting Sei-sama as her knight.""

- --Ran Kurono

Hana no Kishi is a 2010 Shojo manga series by Mai Nishikata.

The Ohtori family is a wealthy and prestigious family that for generations has always been protected by their twelve knights, subordinate families who serve and defend the Ohtori family and its heir Sei Ohtori. The First Knight who defends them is of the Kurono family--specifically Ran Kurono, who following her older brother Rei's death has taken it upon herself to succeed him and strive as the next First Knight, keeping her gender as a woman a secret in order to do so. However, things will not be easy for Ran and Sei in Saint Rogress Academy, where they will be tested among those that would threaten the Ohtori family and Sei.

As fellow knights seek to challenge Ran for her title for their own ulterior motives of using the Ohtori family's authority, Sei is being tested as the future head of the Ohtori family, and Sei's arranged fiance Ibara Tennou discovers Ran's secret, Ran and Sei struggle to overcome their trials.

This series contains the following tropes:
"Ran: [to Midori]"
 * Alliterative Name: Saiki Souda and Shuuya Shizuka.
 * Aloof Big Brother: Ibara's older brother and
 * Alpha Bitch: Karen Asakura, who dislikes Sei for her beauty and popularity and is furious when she mistakenly believes that Houjou is interested in Sei.
 * Always Someone Better:
 * Houjou admits to Ran that her older brother Rei was the only person to ever surpass him in everything and that he will only join Ran and her side of the knights that defend Sei only if she can surpass him in something. Ran surpasses Houjou by having friends that she can trust in.
 * When Houjou finds out that he is desperate to fight him and demands that Sei allow him to fight instead of Ran, but both Sei and Ibara make it clear that Sei's First Knight is Ran.
 * Anguished Declaration of Love:
 * Momokawa confesses to Sei, knowing full well that he'll be rejected because Sei has feelings for someone else. Sei does reject Momokawa, but merely because she puts her duty over her love and own desires.
 * Rin confesses to Ran, but his feelings are unrequited.
 * Arranged Marriage: Between Ibara and Sei.
 * Armor Piercing Slap:
 * Sei slaps Houjou after he steals a kiss from Ran.
 * Ran slaps Ibara after he asks her to return to being a girl and tries to kiss her in Chapter 25.
 * Badass in A Nice Suit: Ran. Ran's father doesn't look too shabby either.
 * Battle Butler: Ran all the way.
 * Because You Were Nice to Me: Ran quickly grows to idolize Souda for tutoring her in math and for being kind to her.
 * Belligerent Sexual Tension: Between Ibara and Ran.
 * Berserk Button:
 * Ran's buttons are pushed if someone so much as suggests she looks feminine or if anyone insults or tries to harm Sei.
 * Ibara, Souda, and even Sei--of all people--are pissed when Houjou kisses Ran, publically humiliating her.
 * Beware the Nice Ones:
 * Sei. She is kindhearted and trusts anyone and everyone to a fault, but do not in any way insult Ran in front of her.
 * Takeru Momokawa. After getting rejected by Sei, he decides to try and be by Sei's side whatever it takes, even by challenging Ran to a duel.

 * Bishounen: Ibara, Souda, Houjou, and Midori.
 * Bittersweet Ending/Earn Your Happy Ending:
 * Bodyguard Betrayal:
 * If the majority of knights betray the future head of the Ohtori family in favor of someone else, that person will have more than enough requirements to be head of the Ohtori family while the future head that was betrayed will be unqualified. Following this past betrayal, Jin's older brother Gen died due to the inner turmoil. Also, currently, half of the knights have denounced Sei as the right heir to the Ohtori family.
 * Bodyguard Crush:
 * Bridal Carry:
 * Ibara carries Sei to the nurse's office after someone pushes Sei down the stairs and later carries Ran when she falls ill and collapses after a duel.
 * Ran carries Sei in the cover of Chapter 18.
 * Brilliant but Lazy: Ibara, much to Ran's shock. He scored first on the entrance exams--ahead of both Sei and Ran, who scored second and third on the entrance exams respectively--but he would rather eat noodles and lounge on the roof reading manga rather than attending class.
 * Brutal Honesty: Souda always speaks what's on his mind.
 * Bifauxnen: Ran.
 * Cannot Spit It Out: Ran plans on never conveying her feelings for Ibara, as she is Sei's knight, Ibara is Sei's fiance, and she wants to protect both of them.

 * The Champion: Ran is this towards Sei.
 * Chekhov's Gun:
 * Ibara steals Kei Tohya's white gloves and learns that there has been someone who has been stealing white gloves. Jin later warns Ran and Sei not to do this, as a knight will be revoked if their rights if they lose their white gloves.
 * Ran and Rin are noted for having a Strong Family Resemblance.
 * Chekhov's Skill: When Ibara and Rin are fighting over Ran, Rin throws sand in Ibara's eyes. Ibara later uses the same tactic on Shizuka for revenge against Shizuka injuring in an unfair fight on one-against-three to the extent that he has to be hospitalized and to use Shizuka's same dirty tactic against him.
 * Childhood Friends: Ran and Sei, Rei and Sei, and Rei and Houjou.
 * Completely Missing the Point: Several times between Ran and Ibara. When Ibara thanks Ran for cheering him up over his situation with his older brother, Ran is confused and mistakes Ibara's thanks for her having to help him find clothing that would compliment Sei's for the dance. Later, Ran misreads Ibara again when she assumes him mentioning the color red meant that she should have chosen a red dress for Sei instead of a sakura-colored dress. Ibara explains that he meant a red dress would suit Ran.
 * Conflicting Loyalty: After Souda challenges Ran to a duel, she is initially conflicted with her duty out of her new found friendship with him. They both get better.
 * Dead Older Brother: Ran's older brother Rei was killed while trying to protect Sei from an attack.
 * Death Glare: Ran's initial reaction to Ibara and his antics. Shizuka has a pretty scary glare too since it even shuts up Houjou.
 * Defeat Equals Friendship: Houjou joins Sei's knights in allegiance to her once Ran surpasses him in something.
 * Defrosting Ice Queen: Ran, who gradually warms up to others after making friends with Ibara and Souda.
 * Dogged Nice Guy: Ibara towards Ran, and Momokawa towards Sei. Ran is a gender-flipped version towards Ibara.
 * El Cid Ploy:
 * Et Tu Brute:
 * According to Jin, he had heard his older brother Gen had died out of inner turmoil following Jin, Shidou, and the knights betraying him and the guardian of Rogress deeming that Gen was "unqualified" to be the next head of the Ohtori family because of this.
 * Ran is briefly shocked after learning that and that Sei had lied to her about it all along, but after a talk with Ibara, Ran's resolve to defend Sei as her First Knight returns.
 * Even the Girls Want Her: Ran and Sei.
 * Everybody Hates Mathematics: Ran does poorly on her math exam and must be tutored by Souda. Though, it is indicated that the partial reason for Ran's grade has to do with her getting distracted over recent attacks on Sei's life.
 * Everythings Better With Princesses: Sei isn't technically a princess, but she's sure treated like one.
 * Evil Counterpart:
 * Houjou can be considered one to Ibara. Both find Ran and Sei amusing and interesting, but Houjou is solely interested in either those who are better than him or those of interest to him and treats everyone like toys.
 * Midori can also be considered one to Ran, as they differ on how to protect the person that is important to them--
 * Face Fault: Ran in Chapter 10, which is lampshaded by Sei.
 * Face Heel Turn: Half of the knights denounce Sei as the "true" future head of the Ohtori family and vow to oppose Sei, Ran, and the rest of her knights.

 * First Name Basis: Between Ran refers to Sei, Ibara, and Rin on first name basis. After getting to knowing Ran, Souda allows her to call him by his first name, "Saiki." Hilariously, Souda declines to call Ran by her first name, as it's difficult for him to say.

 * Ibara tries to kiss Ran, but she stops it in Chapter 25.
 * Generation Xerox:
 * Ran defends Sei with her life, much like her brother Rei did before her and how her father Shidou protects Sei's father Jin too.
 * In Chapter 18, Sei is being opposed by traitorous knights who proclaim that denounce that she is the "true" head of the Ohtori family. As it turns out, in the past, this is what happened to one of the heads of the Ohtori family, Jin's older brother Gen (except he was destructive and violent), and this is what allowed Shidou, Jin, and several knights to betray him, thus making Gen "unqualified" to be the next head and it was passed on to Jin.
 * Green Eyed Monster:
 * Ibara is so furious when Houjou kisses Ran that he has to pick random fights to vent out his frustration. Later on, he is clearly unnerved and jealous by Souda checking Ran's temperature via Headbutt Thermometer and quickly separates them and does the same thing to Ran's cousin Rin when the latter transfers to Ran's school and greets her by hugging her.
 * Sei admits to Ibara that she is envious that Ibara and Souda were the ones who helped Ran open up when she, Ran's childhood friend, could not. Ibara replies that he's envious of the bond that Sei shares with Ran.
 * Hair of Gold: Sei, Momokawa, and Houjou.
 * He Cleans Up Nicely: Ibara during the dance.
 * He Who Fights Monsters:
 * Heel Face Turn: Though Rin wasn't much of a baddie to begin with, he eventually decides to follow Ibara's words and to allow Ran to stay as Sei's First Knight and follow her no matter which path that she chooses out of his love for her.
 * Heroes Prefer Swords: Ran and many of the twelve knights use swords. Ibara, however, prefers using his fists instead.
 * Heroes Want Redheads: Inverted. It is Ibara who is in love with Ran. Then played straight when Ran starts developing feelings for Ibara.
 * Heterosexual Life Partners: Ran and Sei. Shidou and Jin. Houjou and Shizuka appeared to be this early into the series.
 * Hidden Depths:
 * Though Ibara is introduced as a delinquent and a slacker who often ditches class and would read manga, he's shown to be quite perceptive of others, has fast reflexes, and is genuinely concerned for the roles that Ran and Sei must play as the First Knight and future head of the Ohtori family.
 * Akasora-sensei.
 * Honor Before Reason: No matter how many times she risks her life or nearly gets herself killed because of the knight system imposed upon by the Ohtori family, Ran will always protect Sei.
 * Hot Blooded: Ran certainly has a bit of a temper.
 * Hot Dad: Ran's and Sei's fathers, Shidou Kurono and Jin Ohtori.
 * I Just Want to Be Normal: Two interesting variants--both Ibara and Rin, at different times, would rather Ran live the life as a girl than to constantly fight battle after battle and risking her life, and would rather Sei live life as an ordinary girl so her hands would be washed clean of the filthy, bloody world of the Ohtori family. Ran and Sei themselves, on the other hand, want no part in either of this.
 * I Want My Beloved to Be Happy: Ran plans on never confessing her feelings for Ibara because she is Sei's knight (and will live her life perpetually as a man), Ibara is Sei's fiance, and Ran believes that Sei is in love with Ibara.
 * I'll Kill You!: Ran threatens to "dispose" of Ibara if he doesn't straighten up as his behavior threatens Sei's chances at being the head of the Ohtori family.
 * I Will Protect Her:
 * Ran will protect Sei. Always. Ibara, Souda, Momokawa, Rin, and Houjou soon join her in this and to protect both Ran and Sei.
 * In Series Nickname: Ibara often refers to Sei and Ran as "the princess and her knight."
 * Imaginary Love Triangle: During the dance, Karen mistakenly believes that Houjou is interested in Sei, unaware that Houjou is really interested in Ran, and tries to humiliate Sei out of jealousy by throwing water on her. Ran stops it.
 * In the Back:
 * The Ingenue: Sei.
 * Kissing Cousins: Rin reveals to Ran that the reason why he is asking her to give up being a First Knight--and thus putting herself in dangerous situations one after another--is because he's in love with her.
 * Knight in Shining Armor: The Ohtori family's twelve knights are supposed to represent this, but some of them desire to become the First Knight and use the First Knight's privileges of having some of the Ohtori family's power at their disposal. However, the current First Knight, Ran, embodies this trope.
 * Lady and Knight: Naturally, Sei and Ran.
 * Like Brother and Sister: Ran was oblivious to Rin's feelings until he confessed to her is because they were raised like siblings when they were children.
 * Long Haired Pretty Boy: Houjou.
 * Long Lost Sibling:
 * Love Dodecahedron: Sort of. Momokawa has a crush on Sei, who may or may not have feelings for Ibara, who is in love with Ran, who feels the same way. Rin also likes Ran, and Houjou has shown an interest in Ran as well. And then there's that joke about Sei loving Ran (whether it's platonic or romantically is left up to debate), as well as the subtext between Rei and Sei...
 * Love Epiphany: After Momokawa asks Ran for help on confessing to Sei and proclaims how much his heart pounds when he sees her, Ran begins realizing she has developed feelings for Ibara after her heart pounds after sharing his shirt to cover both of them in the rain in Chapter 9.
 * Loved I Not Honor More:
 * Sei admits to Ran that she is in love with someone,, but she will not put love over her duty.
 * Double subverted in Chapter 29.
 * Malicious Slander: Students fear Souda out of rumors that he was held back a year for getting into a fight with several upperclassmen. It turns out that he got into the fight because the upperclassmen were insulting Souda's ill younger brother.
 * Meaningful Echo:
 * Ibara telling Ran that she would look good in a red dress, the same exact thing that her brother told her in the past.
 * Ran reassures Momokawa, who wants to confess to Sei, that his feelings for her--whether he gets rejected by her or not--are not foolish, which are the same exact words that Sei told Ran when she told Sei that she wanted to become a knight.
 * Ran tells Houjou that the one thing she surpasses him in is having friends that she can place her trust in, the exact words her older brother Rei told Houjou.
 * Ibara tells Shizuka that the reason why Ran will defeat Midori is because while Ran places her trust in her friends, Midori does not place his trust in his "friends," mirroring the above words of both Ran and Rei,
 * Meaningful Name: Hana no Kishi means "Knight of Flower" in Japanese.
 * Megane: Akasora-sensei and Shizuka.
 * Missing Mom: Both Ran's and Sei's mothers are nowhere to be seen.
 * Motif: The series uses recurring Arthurian Legend themes, such as the dueling arena for the First Knight challenges being called "The Round Table of Avalon," "Arondight"--the name of Lancelot's sword--is proclaimed before every duel, and the head of the Ohtori family marking its heir's twelfth birthday by following the pattern of King Arthur's Knights of the Round Table and choosing twelve knights to defend the Ohtori family, and the superior of the twelve is chosen as the First Knight.

 * Numerological Motif
 * Oblivious to Love: Inexperienced with love, Ran is unaware that Ibara and her cousin Rin have feelings until they confess.
 * Official Couple:
 * Ojou: Sei.
 * Only Sane Man: Ibara, who can't understand why Ran and Sei are going through such lengths due to the Ohtori family's traditions. Rin acts this way towards Ran, as he initially does not see why Ran would be willing to risk her live for Sei since she is a girl. Even Sei is aware that the Ohtori family's knight system is ridiculous
 * Poisonous Friend:
 * Rin asks Ibara to join him in exposing Ran as a girl so she can stop being Sei's knight and just be a normal girl. Ibara pretty much rejects the idea and calls Rin out on doing something that goes against what Ran wants for herself.

 * School Idol: Ran, Sei, and Houjou.
 * Screw the Rules I'm Doing What's Right:
