2.- Itoshi Rin (Rinsagi)

Rin's favorite food is curry with rice. Her favorite animal is the owl. She lives with her parents and her older brother. Her older brother's name is Itoshi Sae. Itoshi Sae is an omega with dull pink hair and eyes just like Rin's. He is more serious and cold than Rin, and he has a partner named Ryusei Shidou. He enjoys studying or reading mystery novels in his free time.

Rin knew Isagi before, since the omega sat behind him in first grade. Rin had a small crush on Isagi because he was cute and she was curious about Yoichi's shy and kind personality.

Mikage Reo (Omega): He is 18 years old, 1.79 meters tall, and has an athletic and slender build. His hair is purple, and his eyes are expressive violet. He always wears his uniform impeccably and exudes confidence. He is sociable, kind, and very observant. He is also empathetic, protective, and cares deeply for the people he cares about. He is Nagi's partner. He is popular at school because he is a millionaire and very intelligent, with perfect grades.

Nagi Seishiro (alpha): He is 18 years old, very tall at 1.90m, taller than Rin. He is slender but athletic, with very fair skin, messy white hair, and perpetually sleepy gray eyes. He usually wears his uniform neatly, but this is rare. He is very quiet, reserved, and lazy, speaking very little and responding with short, direct sentences. Even so, he is very observant behind his back. He has difficulty expressing emotions, but he is patient, loyal, and very protective. He is Reo's partner and loves him very much.

Rin is very disciplined. He gets excellent grades because he studies every day. He speaks very little and only does so when he has something important to say. He hates drawing attention to himself and hates rumors and gossip. Although many think he's cold and arrogant, he actually has trouble expressing emotions. He's very respectful and doesn't judge people. He's very bothered by stereotypes and comments that try to put down any caste. He's very observant, always memorizing useless things. He almost never smiles, but when he does, it's a small, sincere smile. He's protective of the people he loves and cares about. He doesn't hate omegas; he's just not interested in anyone... until he met Isagi.

Rin is 1.86m tall, making him one of the tallest in his class (apart from Nagi). His build is slim but athletic from playing soccer. He has broad shoulders and his posture is always upright. Her black hair falls somewhat haphazardly over her forehead. Her turquoise green eyes draw attention with their serious and serene gaze.

His uniform is always impeccable: tie neatly arranged, shirt and trousers wrinkle-free, shoes always clean and polished, and he even wears a simple watch. Outside of school, he wears comfortable, casual clothes in neutral and dark colors.
