here's the story
Langa Hasegawa (馳河はせがわ ランガ Hasegawa Ranga?), known in "S" as Snow (スノー Sunō?), is a half-Japanese exchange student who has just returned from Canada to Okinawa, where his mother grew up. He gets caught up in "S", an underground skateboard race, along with Reki Kyan, and the two are quick to become close friends. Unlike Reki, Langa has no skateboarding experience, but his knowledge in snowboarding helped him get a head start. Langa is the main deuteragonist of the SK8 the Infinity anime.
Langa generally wears a neutral or sometimes even stoic expression and when speaking, he tends to use as few words as necessary. As early as his introduction to his classmates, his teacher needs to urge Langa to tell the class more about himself other than just his name, to which Langa adds that he's from Canada, much to the class' amusement.
He is calm and laid back about most things, but when it comes to snowboarding and or learning to skateboard, he's greatly determined and frequently puts his life at risk. Ignoring self-preservation for the act of fun with Reki. He can be an air-headed and easily distracted. He is very self-assured when he is in his element and is a very quick learner. This can be seen when he easily masters riding a skateboard, using his skills from the fifteen years he spent snowboarding. He was able to make quick adjustments, such as quickly learning how to turn on a skateboard, which is different than turning on a snowboard due to the trucks and wheels on the skateboard.
Because he grew up in Canada, he is unfamiliar with many Japanese customs and its culture. For example, he was not used to sitting seiza style during his job interview with Cherry Blossom and so his legs fell asleep. Another example is when he and Reki asked Oka if Langa can work there part-time, Langa lifts his head from the bow too early in a way that would ordinarily be considered impolite.
He's also been endeavoring at getting a job to help out with bills ever since his father's passing. He is also very naturally stubborn and hard working. With the death of his father, Langa has taken the responsibility upon himself to find part-time work in order to help pay bills. Although the pay appears to be most important to him rather than what the job entails, Langa is open about his short-comings, such as when he declined help from Reki in writing his resume in case the job required reading and writing.
He has an apparent distaste for Japanese-styled toilets, preferring the comfort of Western-styled toilets instead. He even makes the Sign of the Cross before he enters the bathroom, a tradition usually associated with Western Christianity than the majority of religions in Asia.
Following his example in all things from habits, skating, and handshakes. He cares deeply for his friends and wants them to succeed as does he wish for himself to succeed. He is close friends with Reki and they spend lots of time together practicing skating.
Langa has a gluttonous appetite, demonstrated when he ate an entire platter of hamburgers when Reki, Miya, Hiromi, and himself went out prior to Reki's beef.
