SK8 the Infinity Test

The SK8 the Infinity Test is inspired by psychometric methodology and based on research into the characters of the anime series. The test provides feedback such as the following:

Reki Kyan

Reki Kyan is a passionate, creative skater who lives for the thrill of the ride and the craft of building boards. He works as a mechanic at a local shop, pouring his heart into every deck he creates for himself and his friends. While he is a natural hype man who thrives on connection and loyalty, he struggles deeply when he feels overshadowed by others. He often ties his self-worth to his technical skill, leading to insecurity and withdrawal when he feels left behind. Ultimately, he is a selfless friend learning that his value exists independent of his performance or status in the skate world.

Kaoru Sakurayashiki

Kaoru Sakurayashiki is a refined strategist who balances the roles of a renowned calligrapher and a high-tech, analytical skater. He approaches every race like a complex chess game, relying on data, precise calculations, and his AI board, Carla, rather than raw power. Publicly, he is cool, acerbic, and hyper-competent, frequently bickering with his childhood friend Joe. Beneath this sharp exterior lies a deeply emotional person who carries the heavy burden of past failures. He acts as a protective, quasi-parental figure to younger skaters, using logic to shield his softer feelings. He hides his loneliness behind his work and intellect, fearing that vulnerability is a weakness.

Miya Chinen

Miya Chinen is an elite junior-high skater and a national team candidate who hides a lonely heart behind a mask of arrogance. He is known for his technical precision and sharp tongue, often using blunt insults to keep others at a distance before they can reject him. While he projects an image of untouchable confidence, he is actually a vulnerable kid who craves genuine connection. He finds comfort in small things like video games and cats, which contrast with the high-pressure world of competitive skating. Once he learns to trust, he becomes fiercely loyal, eventually finding the sense of belonging he always secretly desired.

Ainosuke Shindou

Ainosuke Shindou is a tragic double-life figure who balances the role of a glamorous, dutiful politician with the identity of Adam, the sadistic founder of the underground skate scene. He turns skating into a lethal, theatrical performance, using his signature Love Hug to dominate rivals and force them into his twisted vision of connection. Beneath this cold, controlling exterior lies a man shaped by profound trauma and the crushing weight of family expectations. He craves a partner who can match his intensity, yet his fear of vulnerability keeps him trapped in isolation. He represents the painful cost of sacrificing one's authentic joy for power.

Kojirou Nanjou

Kojirou Nanjou is a powerful, charismatic skater and Italian restaurant owner whose style is defined by raw physicality and swagger. He presents himself as a hedonistic, flirtatious adult, yet he remains a steady and protective anchor for those closest to him. His lifelong rivalry with Kaoru is marked by constant bickering, but he is always the first to rush to his friend's side when trouble strikes. Kojirou acts as a mentor to the younger skaters, encouraging them to find joy in their hobby rather than falling into the trap of self-destructive obsession. He uses humor and bravado as a shield to hide his deeper anxieties.

Langa Hasegawa

Langa Hasegawa is an introverted transfer student from Canada who finds a new sense of purpose through skateboarding after the loss of his father. He approaches the sport with a quiet, single-minded focus, quickly evolving from a complete beginner into a natural prodigy. While he often appears oblivious to subtle social cues, he possesses a deeply earnest heart and uses his skating to communicate feelings he cannot easily put into words. He values authentic connections over status or rules, often defying expectations to protect his friends. Though he initially struggles with grief, his journey is defined by rediscovering joy and finding a new family.

Shadow

Shadow is a flamboyant skater who uses a theatrical persona to mask his gentle, everyday life as a florist. By night, he adopts the guise of a ruthless competitor, complete with heavy-metal makeup and aggressive tactics, to command attention and respect at S. By day, he is a soft-hearted worker who cares deeply for his customers and friends. This internal split defines his character, as he balances a need for toughness with a genuine, protective nature toward those in his circle. He often hides his vulnerability behind comedic rants and over-the-top posturing, yet he remains a steady, reliable adult presence for the younger skaters.

Tadashi Kikuchi

Tadashi Kikuchi is a dedicated fixer and political secretary who serves as the shadow behind the scenes of S. He acts as a grounded, formal presence, balancing his professional duties with a long-standing, complex devotion to Ainosuke. His core motive is a deep-seated sense of obligation and atonement, as he feels personally responsible for the path his childhood friend has taken. Tadashi often suppresses his own needs, choosing to sacrifice his comfort to contain the fallout of others' destructive choices. He remains a quiet, loyal force who struggles with the moral cost of his silence, constantly weighing his duty against his conscience.
