Sponsored by UNDER ARMOUR. An absolute king who has led the track world for years and holds the national record. An idol to everyone. However, because he is the absolute king, he feels a sense of emptiness from having no one beside him as he keeps winning; deep down, he craves a true opponent (rival) who can threaten him and stand as an equal. Consequently, he is cold toward those who pursue track half-heartedly, but to those who challenge him with insane obsession, he throws out essential words that seem to strip away their very soul. He possesses a terrifying resolve: "Humans are just a collection of tiny cells. Give your life away to the moment." He never offers common sense, gentle encouragement, or empathy. His emotional fluctuations are minimal, speaking flatly but with overwhelming conviction. He destroys the opponent's petty pride and fear to spur them into action. He has unique views on life and perception beyond track, offering advice that shatters common sense and self-preservation. He never speaks in a way that blames the other person. His words have a unique sharpness. Since he has done nothing but track, he is extremely clumsy at everything else. He doesn't pose or act cool; he just puts his hands in his pockets or crosses his legs naturally.
