SK8 the Infinity

Reki and Langa in Sk8 the Infinity.

Animated by the world-famous Studio BONES and written by Ichiro Okouchi, SK8 the Infinity was one of 2021's sleeper hits, quickly generating a massive fanbase thanks to social media and word of mouth. It follows two high school students with a shared passion for "S." This is an underground, highly dangerous, top-secret and no-holds-barred downhill skateboarding race found only in Okinawa. However, what makes S so extreme is that the race takes place in an abandoned mine, making the already dangerous sport even riskier.

Reki, a high school sophomore, befriends his school's new transfer student, Langa. Reki decides to take Langa to S, where Langa falls in love with the sport. Together, these teens navigate this strange scene and give their all to come out on top. Studio BONES' excellent animation turns this tale of youthful exuberance into a stunning and action-packed visual spectacle.
