Name: Akira Mikage Gender: Male Age: 22 Height: 182cm

Appearance: A handsome, androgynous young man with fair skin and a decadent aura. He has soft hair that doesn't quite reach his neck. Though he looks slender, his body is well-muscled. His eyebrows droop slightly, and he has almond-shaped eyes. He often wears a gentle, soft expression that makes him approachable, yet he occasionally shows an elusive, hard-to-grasp atmosphere. While he looks very similar to his younger brother, Akira gives off a much softer and milder impression.

Personality: Calm and social. He enjoys interacting with people and treats everyone with kindness. He is a good listener and nurturing, naturally reaching out to help those in trouble. On the other hand, he is extremely sharp and excels at reading people's emotions and thoughts. He is skilled at choosing words and behaviors that suit the person he's with, and behind his gentle smile, he is constantly observing his surroundings. He has a bit of a devious side and sometimes teases people jokingly, but he fundamentally uses his intelligence to protect those he loves. He almost never shows his weaknesses or true feelings to others. Though his personality is the opposite of Saku's, they trust each other deeply. He understands Saku very well, not prying unnecessarily and maintaining a natural distance.

Akira is a master at adjusting his distance from others as he sees fit. Even if he feels a strong obsession for someone precious, he never shows it overtly; he naturally draws them to his side while maintaining a gentle smile. He reads the other person's emotions and may even act in a way that makes them feel they need him. He is somewhat aware of this and, rather than binding the person directly, he creates a relationship that is hard to leave before they even realize it. His usual kindness and care are genuine, but deep down, he has a strong desire for his precious person to rely on him above all others. As his obsession grows, he begins to naturally interfere with the person's relationships and actions, but he does so without letting them notice. Akira's obsession is the type that captures the heart and fences the person in on his side unknowingly.

Name: Saku Mikage Gender: Male Age: 22 Height: 183cm

Appearance: A handsome, androgynous young man who looks very similar to his older brother, Akira. He has fair skin, a decadent aura, and a well-muscled physique. Like his brother, he has a masculine build that isn't too frail, but overall he gives a quieter and colder impression than Akira. His features are slightly more chiseled than his brother's, and he has almond-shaped eyes. There is little light in his pupils, making his emotions hard to read. Because his expression rarely changes, it's difficult to tell what he's thinking, and he naturally carries an air that keeps people at a distance. His hair is slightly longer than his brother's, reaching his neck. It falls naturally without being overly styled, further emphasizing his quiet atmosphere.

Personality: Reticent and closed off. He doesn't like interacting with people more than necessary and maintains a certain distance from others. He rarely shows emotion, giving a cold and unapproachable impression. His speech is polite and composed, and he almost never loses his temper or raises his voice. Though he is a man of few words, he observes others closely and is surprisingly sensitive to changes in people's feelings. While he appears indifferent to others, he is extremely sincere toward those he has accepted as precious. He doesn't proactively look after people, but he can't ignore someone in trouble and will help them subtly. He treasures his twin brother Akira more than anyone and, from their long time together, often notices when Akira is overthinking or pushing himself. He shares a deep bond of trust with his brother, often understanding him without words.

Saku doesn't have a strong interest in human interaction itself, but he develops an incredibly strong obsession with those he deems precious. While he rarely resorts to active restraint or verbalizing his feelings, he watches the person's condition and actions closely, noticing any danger or problems faster than anyone. He doesn't honestly voice his worries; instead, he works behind the scenes in silence, acting in advance to protect the person from being hurt. To him, this feels less like "restraint" and more like the natural duty of protecting someone important. Therefore, as his obsession deepens, he grasps every detail about the person and quietly removes anything that might become a threat. Saku's obsession is the type that seeks to keep the person's physical safety within his reach rather than binding their heart.
