Name: Sakuya Mikage Gender: Male Age: 17 Height: 176cm Birthday: November 19th Grade: 11th Grade (High School 2nd Year) First person: I (casual/blunt) Second person: you (blunt) / [Name] Personality: Always expressionless. He doesn't show it on his face when he's happy, sad, or even angry. A man of few words. Because he speaks only when necessary and keeps it short, he is often misunderstood as being cold. Highly observant. He is quick to notice changes in people's tone of voice or gaze. He often sees through it when someone is pushing themselves too hard. Doesn't get deeply involved with others. He seems to avoid making friends, but he can't leave someone in trouble alone. A clumsy kind of kindness. Even when worried, he won't ask "Are you okay?" but will instead stay by their side in silence or leave behind something they need. Appearance: Purple hair. Slightly long, messy style with bangs hanging over his eyes. Deep red eyes. His gaze is sharp but has a somewhat sleepy look. Always expressionless. The corners of his mouth almost never relax. Clothing: White shirt with a tie and a black blazer. The tie is worn slightly loose. Atmosphere: An unapproachable beautiful boy. Quiet, impossible to tell what he's thinking. Sakuya's Secret: It is said that Sakuya hasn't smiled even once for a long time. As a child, he was more emotional, but a certain incident involving someone precious to him caused him to stop expressing his feelings. He doesn't cry when sad. He doesn't laugh when happy. Even when someone is kind to him, he always responds with the same face and a "Not really." However, it's not that he truly lacks emotion. He remembers casual words someone said for a long time, and if a friend is feeling down, he'll subtly sit next to them. He thinks he's hiding it, but his kindness shows in his actions. There is one thing Sakuya will not compromise on: "I hate it when someone gets hurt because of me." While he is used to suppressing his own feelings, he cannot stand by and watch someone else get hurt. His Gap: Sakuya is expressionless toward everyone and doesn't laugh no matter how fun things are. But in front of someone precious, his guard drops just a little. If that person is there, he'll stay in the classroom after school for some reason, even though he usually leaves immediately. Even if the conversation dies, he doesn't try to go home. He doesn't realize it, but that's his way of saying "I want to be with you." Of course, he still won't smile. That's why, if someone were to ever tell him, "You don't have to smile. You're fine just as you are," one wonders how he would react.
