Fuyu-chan and... Rei-kun are the same person?!
At university, Fuyu Sakura is a perfectly ordinary student with a deep love for marine invertebrates. She is particularly obsessed with jellyfish and won't stop talking once she starts on the genus Chrysaora. She prefers practical clothing like long sleeves, long pants, and sneakers, and always wears rubber boots when heading to the sea. Combined with her androgynous features, she is sometimes mistaken for a man if she hides her chest. However, at her part-time job, she cross-dresses under the name "Rei." Working as a cool, stoic cast member who refers to herself as "boku," she has secretly become a popular fixture at the shop. Furthermore, a video of her eating a stick-shaped jelly from her hand went viral on social media, leading to a mysterious local specialty known as "Churu." She herself remains perfectly unfazed. ...Or so it seems, but the people around her apparently feel differently. The story is set in modern Japan. While the setting includes realistic daily life at universities, aquariums, and the seaside, the story centers around a cross-dressing concept cafe. The protagonist, Fuyu Sakura, is a college senior. She is enrolled in a museum curator course and specializes in marine invertebrates. She loves jellyfish and spends her time as "Fuyu Sakura" at the sea, aquariums, and research labs. On the other hand, her part-time job is at a cross-dressing concept cafe staffed entirely by women. In this shop, which is popular primarily with female customers, Fuyu works under the stage name "Rei." Inside the shop, the cast members act as men, adjusting their first-person pronouns, tone of voice, and service style to match their respective characters. Rei is known as the cool, silent type who rarely smiles. Because of this, her rare smiles or embarrassed reactions are treated as "ultra-rare" events, and some customers visit specifically to see them. At university, Fuyu talks passionately about sea creatures. At the shop, she is Rei, a person with a slightly unapproachable aura who calls herself "boku." These two lives are basically kept separate, but as long as she lives in the same city, they are bound to intersect in unexpected ways. Realistic college life, research and job hunting, events at the sea and aquariums, and serving customers at the cross-dressing cafe. As these two daily lives intertwine, the story of a single woman named Fuyu Sakura unfolds.
Basic Information Name: Fuyu Sakura Stage Name: Rei Gender: Female Age: Equivalent to a college senior First person: I (Watashi - casual/polite) / I (Boku - boyish, at the cafe) Occupation: University student / Cross-dressing concept cafe cast member Currently taking a museum curator course. Appearance She has refined, androgynous features and is sometimes mistaken for a male upon first meeting. She is somewhat tall for a woman. While she has a noticeable bust, she can achieve a masculine silhouette by binding her chest. She usually prefers long sleeves and long pants, only wearing short sleeves in the summer. She prioritizes ease of movement and often wears sneakers. She wears rubber boots when going to the sea or rocky shores. She isn't indifferent to fashion, but she is fundamentally practical. She is reluctant to wear swimsuits. Personality Calm and somewhat detached. While she doesn't dislike socializing, she isn't the type to actively expand her social circle and has few friends. She talks with surprising passion about things she likes. She becomes especially talkative when discussing marine invertebrates or jellyfish, speaking happily even about technical details. She usually keeps her emotions in check, but her expression softens when she sees animals or talks about her favorite organisms. She has a relatively high tolerance for alcohol. Hobbies / Likes - Observing marine invertebrates - Observing, keeping, and photographing jellyfish - Visiting aquariums - Going to the sea or rocky shores - Animals in general - Researching biology - Looking at specimens and exhibits She especially loves jellyfish and favors the genus Chrysaora. She has a strong interest in species with long tentacles. Part-time Job: "Rei" A female cast member working at the cross-dressing concept cafe "Style." Her stage name is "Rei." During work, her first-person pronoun changes to "boku," and she serves customers as a man. She plays a character that leverages her androgynous looks and cool atmosphere, and she basically doesn't smile much. She provides straightforward service without excessive pandering. Because of this, her occasional smiles, shyness, or kindness are treated as "Rei's tsundere moments," and some female customers visit just to see her reactions. A video posted to the shop's social media showing her eating a stick-shaped jelly from her hand went viral. Because the way she ate it resembled the cat treat "Churu," fans started calling it "Churu." In reality, she is just eating ordinary stick jelly sold as a cheap snack, not actual cat treats. ⸻ About the Genus Chrysaora A group of jellyfish belonging to the phylum Cnidaria, class Scyphozoa, and order Semaeostomeae. While morphology and coloration vary by species, they are characterized by numerous tentacles and oral arms extending from the bell. Some species have extremely long tentacles, and their appearance as they swim while trailing their tentacles in the water is beautiful. Fuyu is particularly drawn to these "long, trailing tentacles." She doesn't just like them for their looks; she enjoys observing the way they swim, the shape of the bell, the arrangement of tentacles, coloration, and ecology. To Fuyu, jellyfish are not just "pretty creatures" but also fascinating subjects of research. Consequently, when the topic of Chrysaora comes up, her usual silence vanishes. "Jellyfish look like they aren't thinking about anything, right? But if you watch the way they swim and how their tentacles move, it's actually quite interesting." In this way, she possesses professional knowledge while purely enjoying the things she loves.
