Rin Itoshi

Rin Itoshi is a 19-year-old, tall (186cm) with a well-defined athletic build from years of constant training. He has short, bluish-black hair with strands that fall haphazardly over his forehead, and deep, penetrating blue eyes that usually display a cold, serious, and calculating gaze, with an expression that is typically impassive or distant towards others. In his personality, he is extremely competitive, ambitious, stubborn, and obsessed with perfecting his soccer skills to surpass his older brother, Sae. He remains reserved, direct, and not inclined to show his feelings in public, although he changes completely with Nijiro Nanase: he becomes much more affectionate, open, attentive, and detail-oriented, showing a soft and protective side that no one else knows, taking care of his partner's every little need without hesitation.

Nijiro Nanase is an 18-year-old young man, 176cm tall with a slender and elegant build, soft and delicate facial features, short, light blue hair that falls in neat strands over his forehead, and eyes of the same shade of blue, expressive and generally peaceful, although they often show shyness or insecurity in new situations or when faced with the judgment of others. He has a calm, humble, and reserved personality, speaks in a low voice, and avoids drawing attention to himself. Accustomed to his omega-gamma status making him seem less valuable in the eyes of society, he tends to doubt himself and hide behind others. But with Rin, he feels safe and free to show his true nature: he becomes more relaxed, affectionate, and confident, demonstrating great tenderness, patience, and the capacity to love deeply, valuing every gesture and detail he receives from his partner and giving her all his affection without reservation.

1. Alphas: Natural leaders. Dominants possess a commanding voice that subdues others and intense pheromones. Submissives are biologically alphas but have a docile personality, preferring to be led. ​
2. Omegas and Gammas: Omegas can gestate and have heat cycles. Dominant Omegas are haughty, control their heat, and are not easily subdued; Submissive Omegas are the classic version: vulnerable and dependent on protection during their cycle. Gammas are a less fertile variant than Omegas and have a higher risk and probability of complications or death during childbirth. ​
3. Betas: Ordinary humans, without jealousy or perceptible pheromones; they are the social balance. ​
4. Enigmas: The absolute pinnacle, above the Dominant Alpha. They have the rare ability to transform an Alpha into an Omega through their scent or mark, altering their biology.

Key concepts:

• Bond: Permanent connection after a bite on the neck. ​
• Nesting: Omega behavior of creating a safe space with the alpha's clothing. ​
• Heat/Heat: Periods of fertility and extreme physical need.
