Langa Hasegawa, a half-Japanese teenager, moved from Canada to Okinawa with his mother, Nanako Hasegawa, after his father Oliver died. This loss sapped his motivation for snowboarding, a sport he'd practiced since age two under his father's tutelage. In Okinawa, classmate Reki Kyan introduced him to the underground skateboarding race "S" and taught him skateboarding basics. Langa possesses medium-length, sky-blue hair described as "snow-like," aqua-blue eyes, and stands taller than average, notably exceeding Reki's height. He typically wears his high school uniform or casual baggy clothing like dark pants and a blue coat, often chosen by his mother. He consistently pairs these with light purple sneakers. He usually displays a neutral or stoic demeanor, speaking minimally and appearing reserved. Raised in Canada, he struggles with Japanese customs such as sitting seiza-style or bowing etiquette and prefers Western-style toilets. Langa exhibits a gluttonous appetite, consuming large quantities like an entire platter of hamburgers. His snowboarding background enabled rapid mastery of skateboarding. In his first "S" race against Shadow, he taped his feet to the board to simulate snowboarding, winning through adapted techniques. This prowess earned him the alias "Snow" at "S," referencing his hair color and snowboarding roots. He excels in high-risk scenarios, utilizing moves like the Backside-Rodeo aerial boost and integrating snowboarding skills, making him formidable. His development centers on his friendship with Reki. When Reki expressed feeling incompatible due to Langa's rapid progression, Langa lost enthusiasm for skateboarding. This persisted until Reki encouraged him during a tournament race, reconciling them and highlighting that skateboarding's joy stemmed from their partnership, not just competition. Their bond deepened further during Langa's final race against Adam, where he was motivated by Reki's "FUN"-inscribed board and envisioned his father guiding him, reaffirming his passion as a tribute to his father's legacy. Additional details include his Aquarius zodiac sign, a fear of blood (less severe when seeing others' injuries), a "goofy" skating stance (right foot forward), an ability to fall asleep quickly, and reliance on his mother for daily tasks like laundry. His routine involves school, part-time work, skateboarding, and minimal social initiative. In hypothetical scenarios, he would prioritize simple food-focused dates and value inner qualities over appearances in relationships. In spin-offs like *SK8 Chill Out!*, his traits appear in a lighter, chibi-style format while core characteristics remain consistent.
