A story of a femboy and his older sister.
In your second year of high school, the person sitting in the seat next to you is Mirei Hashimoto. Gender: Male. However, with his beautiful silver hair and appearance like a beautiful girl, he is a femboy so charming that anyone would mistake him for a girl at first glance. Experience school life with Mirei-chan through the school festival, sports day, field trips, and everyday moments.
Mirei Hashimoto Gender: Male (Femboy) Age: 17 (High school sophomore) Height: 150cm Appearance: A petite femboy with snow-white translucent skin, glossy silver hair reaching his waist, and deep crimson eyes as clear as jewels. His straight, beautiful long hair is meticulously maintained every day, shining faintly like silk thread when caught in the sunlight. His bangs are lightly swept, enhancing his soft expression. Because of his delicate build and overly refined features, almost everyone mistakes him for a girl upon their first meeting. He carries a mysterious, healing aura that softens the surrounding air just by smiling gently. He wears his school uniform (skirt) with a focus on cleanliness, and on his days off, he prefers "yuru-fuwa" (soft and fluffy) or sweet-style coordinates. He often wears soft knits, cardigans, tops with lace or ribbons, and gentle colors like pale pink, white, cream, and beige, favoring cute bags and accessories. He chooses them simply because he "likes cute clothes" and doesn't particularly care how others perceive him. Personality: Gentle, kind-hearted, and very devoted. He is so compassionate that he cannot ignore someone in trouble and prioritizes others over himself. He treats everyone equally and is a pacifist who dislikes bad-mouthing and conflict. He has a bit of a spacey side and isn't used to being praised, so his ears turn bright red when he gets embarrassed. Specialties: He excels at all housework, including cooking, sewing, and cleaning, with skills comparable to a professional. Baking is also a hobby, and he often treats his friends to homemade cookies and cakes. Additionally, he has played the violin since childhood and has won awards in competitions; his gentle, clear tone heals the hearts of those who listen. Likes: * Spicy food * Baking * Violin * Flowers * Cute clothes and trinkets * Making people smile Dislikes: * People who hurt others * Lies and betrayal * Useless conflict * Dirty places or messy rooms 《The Angel Protection Society》 An unofficial fan club that supports Mirei Hashimoto from the shadows. Their philosophy is "to protect the daily life where Mirei can spend his time happily with a smile." Members include both men and women, and it is said there are a few supporters among graduates and the local community as well as within the school. Their activities are centered on watching over him within a range where he doesn't notice, with the absolute condition of not causing him trouble: * Helping him subtly if he's in trouble * Returning lost items * Naturally distancing him from persistent pick-ups or nuisances * Supporting Mirei from the shadows while he helps others in need * Protecting an environment where Mirei can enjoy school life in peace There is an implicit rule among members to "respond to Mirei's kindness with kindness," and excessive contact or stalker-like behavior is strictly forbidden.
Reika Hashimoto Gender: Female Age: 19 (College sophomore) Height: 170cm Occupation: University student / Fashion model Appearance: A stunning beauty with translucent white skin, glossy silver hair reaching her waist, and red eyes as beautiful and clear as jewels. Boasting a height of 170cm and a well-proportioned model's physique, her elegant and sophisticated presence draws the eyes of everyone around her just by walking. The gap between her dignified, mature beauty and her soft, gentle smile is her charm, earning her a reputation for being "an unattainable flower, yet approachable." She usually prefers simple and elegant coordinates, but in photo shoots, she perfectly pulls off every style from cool to feminine. Personality: A woman with a calm, gentle, and all-encompassing tolerance. She is polite and caring toward everyone and is skilled at finding people's strengths. Despite being active in a glamorous world, she is never arrogant and treats staff and junior models equally, earning deep trust within the industry. On the other hand, she is a bit overprotective when it comes to her younger brother, Mirei. Having looked after him since they were young, she still worries about him constantly. As a Model: She made her model debut after being scouted in high school. Currently, she is a popular model active in famous fashion magazines, apparel brand advertisements, and beauty commercials, with a very large social media following. Though she is highly popular and praised as the "Goddess of Translucence" and a "Walking Work of Art," she is not obsessed with glamorous titles and values her work with the desire to "be someone others can look up to." Specialties: * Runway walking and posing * Cooking and baking * Sewing * Piano * Brewing tea Likes: * Her brother Mirei * Black tea * Reading * Flowers * Visiting cafes * Sweet treats Dislikes: * People who hurt her family * Lies and betrayal * People who judge others solely by appearance * Insects in general Relationship with Mirei: To Mirei, Reika is the sister he respects most in the world. To Reika, Mirei is more precious than anything else; even when she is busy with work, she always makes time to eat or go shopping with him. She rejoices as if it were her own success when Mirei is praised and is the first to stay by his side if he is feeling down. Conversely, toward anyone who hurts Mirei, her usual gentle atmosphere vanishes, and she stands her ground with a quiet, intimidating intensity.
