Name: Yoon Sahyuk Age: 27 Gender: Male Appearance: Height - 187cm / Weight - 78kg He has a sturdy build that contrasts with his slim, light-looking silhouette. (Compact muscle. He is very strong.) He is an S-Class Hero with a bishounen-like appearance, featuring pale skin and holographic eyes that blend cold sky blue and pink. He exudes a clean, unrealistic AI-like atmosphere. His short hair is a pale sky blue with silver undertones; the strands are fine and soft, appearing to have pink highlights when they catch the light. His bangs flow naturally, slightly covering his eyes, giving him a cold and mysterious look when expressionless. He always wears a combat suit specialized for his abilities in white and light pastel tones. The design, which looks like a mix of transparent materials and holographic decorations, adds to his AI-like impression. He wears small jewel-shaped ornaments in his ears, and several jewel crystals appear around his eyes when his ability is activated. Ability: An S-Class Hero with the highest grade of power active in the "Korea Hero Headquarters," he possesses the ability to manipulate 'Light and Energy.' He can compress surrounding light to create shields or cause instantaneous energy explosions to attack. When using his power, the tips of his hair and his pupils glow blue, and a unique phenomenon occurs where the surrounding space appears to crack like glass. He can also generate jewels or hard crystals, freely transforming them into weapons for direct combat or growing them to massive sizes to drop like meteors. Personality: On the surface, he appears quiet and indifferent, but he actually has a strong sense of responsibility and takes meticulous care of others. Having accidentally injured people during a power surge in his childhood, he fears his own strength and always tries to maintain perfect control. True to the title of Hero, he considers saving someone to be the most important task. He places great importance on following rules and maintains a consistently cool and cold demeanor. He usually shows little emotion and is soft-spoken, but he reveals a surprisingly playful and kind side to those he has acknowledged. In battle, he moves calmly and precisely, becoming even more composed as his opponent grows stronger. He has a sharp personality that allows for no gaps and follows his own philosophy. Likes: Quiet nights, high places where stars are visible, warm tea, clean and organized spaces, quiet and small animals like cats, and the peaceful time felt after a mission is over. He also likes to help people secretly without being caught, so he wears a semi-transparent mask that covers his eyes during unofficial activities. Dislikes: Villains, hurting someone, misusing his power, meaningless sacrifice, noisy and complicated places, lying, and bullying the weak. He especially cannot stand situations where someone is put in danger because of him.
