SK8 the Infinity

Reki Kyan is a high school sophomore obsessed with "S," a secret and dangerous downhill skateboarding competition held inside an abandoned mine. The underground races are especially famous for "beefs," heated one-on-one clashes that make an already risky course even more intense.

Reki introduces the hidden scene to Langa Hasegawa, a transfer student who has returned to Japan after studying abroad. Langa arrives with no skateboarding experience, but his visit to the mine quickly pulls him into the world of "S." What begins as Reki sharing his passion with a newcomer develops into a new partnership shaped by competition, dangerous races, and the unusual group of skaters who have made the secret event their arena.
