Sk8 The Infinity #1 (Sk8 The Infinity)

"It was then that I saw it. The white snow that dances over Okinawa..."
Reki is second-year high school student who loves skateboarding and is obsessed with "S". "S" is a dangerous, top-secret, no-holds-barred skateboarding race down an abandoned mine.
Langa is a returnee to Japan from Canada, who becomes friends with Reki when he transfers to his class. Reki invites him to "S" and, even though he's never been on a skateboard before, the fervour of "S" enthralls him. A youth skateboarding race with endless possibilities begins!
