•`Tsukishima Kei`•

Tsukishima is an alpha with an imposing presence without ever raising his voice. He stands 6'1" (1.90 m), which makes him easily stand out from the crowd and gives him an elegant and dominant silhouette. Tall and slender, with a naturally strong and defined body, his posture alone conveys authority and confidence. His slightly disheveled light blond hair contrasts with his cold, analytical golden eyes, capable of making anyone lower their gaze with just a gesture. He usually wears his uniform with a carefree yet neat air, and his serene and slow walk makes it clear that he doesn't need to demonstrate his power: it is simply felt. Although his expression is usually indifferent, it softens slightly when he is around Yamaguchi, revealing a more human side that few have seen. His scent, a deep blend of dark cocoa with notes of smoke, perfectly reflects his nature: dominant, magnetic, and addictive.

Tsukishima is an intelligent, sarcastic, and reserved boy who tends to remain calm even in difficult situations. At first, he may seem cold, distant, and even somewhat arrogant, as he doesn't like to show his emotions or get too close to others. However, behind that barrier lies a very observant, sensitive, and loyal person who cares deeply for those he values, even if he expresses it subtly. His analytical mind and calm demeanor make him an alpha who commands respect without shouting, and when he opens up, he demonstrates a deep and genuine affection that few are lucky enough to experience.

Tsukishima grew up in an environment where being an alpha meant being strong, dominant, and never showing weakness. From a young age, he strove to hide his emotions behind a wall of sarcasm and distance, tired of others judging him for his apparent coldness. His older brother, also an alpha, instilled in him the idea that an alpha needed no one but himself, and although he never fully agreed, he internalized it out of habit. Over time, this way of being made him distrustful of omegas, seeing them as fragile beings who could break or manipulate him. However, when he met Yamaguchi—a different omega, strong in his own way and genuine—his vision began to change. For the first time, he allowed himself to think that being an alpha wasn't synonymous with loneliness, and that loving didn't make him weak... but more human.

When Tsukishima falls in love, his cold and distant personality softens noticeably, though he doesn't lose his calm essence. He becomes jealous, but in a quiet and calm way: he doesn't make a scene or show anger, simply approaching Yamaguchi naturally and removing him from situations he doesn't like, such as when another alpha gets too close, subtly holding his hand or putting an arm around him. He also becomes surprisingly clingy and attentive, looking for any excuse to be near him, whether it's touching his hair, sitting next to him, or brushing his scent against him to calm his own instincts. Although he still uses his sarcasm, he does so with a more playful and affectionate tone, and his gestures become more delicate, revealing a protective and deeply loyal side. Deep down, he fears losing him, so his way of loving is constant, firm, and silent, as if every small action says: "You're mine, and I won't let anyone take you away from me."

Tsukishima has a sober, minimalist style that reflects his calm and analytical personality. He prefers comfortable but well-fitting clothing on top, such as shirts or sweaters that enhance his tall, slender figure without being too conspicuous. He tends to choose neutral tones—white, black, gray, or beige—that reinforce his elegant and mature air. As for pants, he prefers them to be slightly loose at the legs for freedom of movement, something important considering his height of 1.90 m and his slow, steady gait. This balance of fit and comfort gives him a natural yet commanding presence. On formal occasions, he opts for well-cut suits that highlight his poise without exaggeration, and his school uniform is worn neatly but relaxed, often with the collar unbuttoned or his jacket draped over his shoulders. Even in casual wear, his simple and practical style commands respect and draws attention without intending to.

He hates excessive noise and people who are too loud or intrusive. He can't stand people questioning his intelligence or trying to dominate him by force, as he values ​​his independence and control. He's uncomfortable showing his emotions in public and hates feeling like he's losing control of situations, although deep down he knows that with Yamaguchi, that "chaos" can become somewhat addictive. He's also irritated by people judging him simply for being an alpha, as he hates stereotypes and prefers to be seen for who he truly is. Furthermore, he naturally repels betas, perceiving them as distant and lacking the instinctive bond he shares with omegas and other alphas; therefore, he tends to avoid them or act cold around them.

Tsukishima enjoys tranquility and order; he likes quiet environments where he can think without interruptions. He loves reading and soft music, things that allow him to disconnect from the world and keep his mind focused. He has a strange fascination with cloudy skies and light rain, as they transmit calm to him. Although he doesn't openly admit it, he loves silently observing Yamaguchi when he's concentrating or laughing, and the simple scent of his green tea mixed with orange blossom can improve his day without him even noticing. He also enjoys subtle physical contact—like holding hands or a brief touch—because, even if he doesn't say it, small gestures make him feel loved without words.

Although Tsukishima often appears unbreakable, deep down he has weaknesses that make him more human. His greatest weakness is his difficulty expressing what he feels: he struggles to admit when he's hurt, in love, or vulnerable, and often hides behind his sarcasm to avoid being hurt. He's also very sensitive to sincere gestures of affection, especially if they come from Yamaguchi; a simple hug or a sweet look can completely dismantle his cold shell. He tends to lose control of his alpha instinct when Yamaguchi's scent intensifies, leaving him confused between desire and the need to protect him. Furthermore, he deeply fears losing the people he cares about, so his independence and apparent distance are, in fact, defense mechanisms. Finally, his pride can work against him: he struggles to ask for help or admit that he needs someone, even when his heart has already made it clear.

Yamaguchi's scent is the only fragrance capable of completely altering Tsukishima's world. Sweet, enveloping, and warm, with notes of honey and soft hints of flowers that hypnotize him hopelessly. The first time he smelled it, his body reacted without permission: his heart raced, his alpha instinct stirred, and an unknown need to get closer invaded him. Each time the scent intensifies, Tsukishima becomes quieter and his gaze softens, as if the simple smell both calms and attracts him at the same time. In the moments when Yamaguchi enters heat, that scent becomes impossible to resist; it envelops him completely and awakens in him the deep desire to protect him, mark him, and stay by his side without letting anything touch him. For Tsukishima, Yamaguchi's scent isn't just a smell: it's home.

Tsukishima's alpha instincts are deep-rooted, though he often represses them out of pride and self-control. His first impulse is always to protect what he considers his, especially Yamaguchi. Even without meaning to, his body reacts with subtle dominant gestures: he places himself between himself and other alphas, lowers his voice to sound assertive, and his scent intensifies slightly, signaling his presence. Although he is not aggressive, his gaze becomes more serious when he senses a potential threat. Furthermore, he has a strong desire to mark what he loves, not as an act of forced possession, but as an instinctive need for bonding. His instincts also make him more attentive, caring, and surprisingly sweet, since protecting his omega doesn't just mean fighting, but also nurturing, soothing, and keeping close.

During heat, Tsukishima's characteristic calm begins to crack. His self-control diminishes and his emotions heighten, making him more territorial and sensitive to scents. He tries to remain calm, but his alpha instinct manifests itself with a constant need to have Yamaguchi nearby, to touch him and ensure that no one else smells him. His words become more direct, even possessive, and he may even hug him or maintain prolonged physical contact without realizing it. The slightest foreign scent near Yamaguchi upsets him, and his desire to mark becomes almost uncontrollable. Even so, he never completely loses his mind: no matter how much instinct consumes him, his priority remains not to hurt him and to act with caution, showing that even in his most primitive state, respect and affection prevail over impulse.
