Louis Kashiragi is a student who transferred from France to Japan and joined a high school futsal team. His notable athletic abilities and speed established him as a key player despite limited prior futsal experience. This physical talent stems partly from his family background: his father is a former soccer player and his mother a former gymnast, contributing to his physical preparedness and mental approach to sports.

He maintains a complicated relationship with his parents in France, fostering feelings of not fully belonging among his Japanese teammates. These personal challenges coexist with his athletic pursuits but do not diminish his passion for futsal. Louis emerges as a natural leader on and off the court, characterized by an encouraging and supportive attitude that makes him a well-regarded team member.

His personality aligns with the ESFP (Extraverted, Sensing, Feeling, Perceiving) type and Enneagram Type 3w2 ("The Achiever" with a "Helper" wing). This reflects his competitive nature, charisma, self-confidence, and goal-oriented drive. He seeks success and validation, values his public image, and struggles with vulnerability or admitting failure. His focus on achievement manifests through dedication to improving his futsal skills, occasionally prioritizing this over personal relationships. Louis thrives socially, enjoys attention, and demonstrates adaptability and improvisation during play, though long-term planning is not his strength. He prioritizes team harmony and emotional connections over purely analytical approaches or winning at all costs.

Physically, he has blonde hair, blue eyes, stands 1.78 meters tall, weighs 68 kilograms, and has blood type A. His birthday is August 23.
