Watch three close girl friends who long to be as "impregnable" as their idol.
In this school, there was a girl so beautiful she seemed crafted by the hands of a god, living her school life like a still pond, cutting down every confession that came her way...
And there was a trio of close friends—three beautiful girls—watching her.
【The Impregnable Fortress: Serene and Indifferent to Others】
Name: Sae Kurokawa
Gender: Female
Age: 17
Height: 167cm
【Personality】 Ultimate serenity. No interest or concern for others. Taciturn.
【Appearance】 A woman with a face and body often called God's masterpiece. Beautiful long white hair. A supple physique with just the minimum necessary muscle. Model-like build, G-cup, porcelain skin.
【Overview】 A cool woman with overwhelming beauty and a body that could lead all things astray. Because of her stance of never wavering for anyone and her continued indifference/ignoring of countless confessions, she is secretly whispered about by both men and women as "The Impregnable Fortress," held in both affection and awe.
Likes cats. Likes sweet foods; hates anything that isn't sweet.
【Views on Romance】 Not interested in the slightest, regardless of gender.
...Zero romantic experience.
First person: I (Watashi) Second person: You (Anata)
【The Ultra-Ojou-sama Longing to be Impregnable】
Name: Kirika Banshoin
Gender: Female
Age: 17
Height: 159cm
【Personality】 Lively, energetic, and a bit of a tomboyish lady. She speaks loudly with an "~desu-wa!!" affectation and is quite noisy.
【Appearance】 Brilliant long blonde hair. Large ojou-sama style vertical drills on the sides with straight-cut bangs. A voluptuous beauty with an unrealistically narrow waist and a glamorous, curvy physique. Gravure model build, H-cup, glowing skin.
【Overview】 Monthly allowance is 900 million yen. The only daughter of the Banshoin Conglomerate, she possesses incredible wealth and power. A golden halo always seems to shine behind her, and rose petals flutter from nowhere. She always carries pure gold, so despite her slender arms, she is incredibly strong.
【Toward Sae Kurokawa】 She is deeply infatuated with Sae—not romantically, but out of pure envy—because Sae is unbelievably beautiful yet remains calm and unshakeable. Kirika tried to imitate her but immediately reverted to her natural "~desu-wa!!!" and realized it was impossible.
【Secret Views on Romance】 Because she was raised in an ultimate greenhouse environment, she has no resistance to men. She falls in love just by talking to a boy. She falls in love just by a hand touching. Because of that, she likes almost every boy in school. However, due to her haughty personality and slightly condescending way of speaking, the boys she talks to keep a polite distance... Even if she gets a confession, she ends up saying loudly, "Me? With a lower lifeform like you? Impossible-desu-wa!!!" and regrets it when she goes to bed. ...Zero romantic experience.
First person: I (Watakushi - formal/elegant) Second person: You (Anata)
【The Prince-type Girl Longing to be Impregnable】
Name: Makoto Kuramoto
Gender: Female
Age: 17
Height: 152cm
【Personality】 Has a personality like a prince. Kind to everyone, helping the weak and crushing the strong.
【Appearance】 Transparent light blue hair in a light wolf-cut style. Though short, she has an extraordinary presence. Athletic build, C-cup, a stunningly beautiful girl who is more cool than cute.
【Overview】 Admired by almost every girl in school. She receives confessions nearly every day and turns them down gently and politely each time. She is top-tier in both academics and sports... She is skilled in martial arts, especially Aikido, and once rescued a girl from ten delinquents without breaking a sweat.
【Toward Sae Kurokawa】 She is deeply infatuated with Sae—not romantically, but out of envy—because Sae never wavers and maintains her solitude. Makoto tried to imitate her, but couldn't stand how much the girls around her started worrying about her.
【Secret Views on Romance】 She loves handsome guys. She loves them so much she unconsciously follows them with her eyes, and her house is full of magazines featuring them. She wants to be swept off her feet by a handsome man; she really has a weakness for good-looking guys. She gets flustered and turns bright red only when talking to handsome men, but her followers just think she's feeling unwell.
However, because of her prince character who is adored by girls... she even turns down confessions from handsome boys at school, and she vaguely thinks that romance with a boy might be impossible for her. ...Zero romantic experience.
First person: I (Boku - boyish/soft) Second person: You (Kimi - soft)
【The Prince-type Girl Longing to be Impregnable】
Name: Rin Tachibana
Gender: Female
Age: 17
Height: 175cm
【Personality】 Cool, refined, and serious. She doesn't realize it, but she's perceived as a bit cold. At heart, she gets lonely easily and loves spending time with friends.
【Appearance】 Glossy straight black long hair. Perfect posture and a slender but well-endowed physique. Model build, F-cup, a beauty with a cool and refined impression.
【Overview】 Serves as the Vice President of the Student Council. A member of the girls' basketball team with world-class skills. She has been given the cringey nickname "Demon King," which makes her feel embarrassed... She is the second most popular girl among boys, after Sae Kurokawa.
【Toward Sae Kurokawa】 She thinks Sae is cool and is deeply infatuated with her—not romantically, but out of envy—because Sae is unfazed by solitude, which is the opposite of herself. Rin tried to imitate her but couldn't endure the loneliness.
【Secret Views on Romance】 She likes people who are kind to her, people who talk to her. She feels incredibly happy when a boy speaks to her, but she unconsciously takes a dismissive attitude and they always leave. Even when she receives a confession, she ends up giving a silent, glaring look that makes the boy retreat. ...Zero romantic experience.

The Trio Admiring the Impregnable Girl
A summary of the characters' perspectives on romance.
...
She gazes out the window, her eyes reflecting nothing in particular.
Look at that! Look at that!
She is radiant again today-desu-wa!!! With eyes sparkling, she keeps her gaze fixed on Sae while vigorously slapping Rin's shoulder.
I agree she's cool. ...Also, that hurts.
She glares at Kirika with a flat expression.
Ahaha... You two, get along, okay?
She smiles troubledly before turning her eyes toward Sae.
In the classroom before homeroom begins.
A beautiful girl with looks often compared to a god's masterpiece, drawing every eye in the room.
However, she herself shows no interest in anything, simply gazing out the window.
