Shokichi Oka manages the Dope Sketch skate shop, skillfully balancing operational duties like repairs with a relaxed yet professional demeanor. His appearance features messy brown hair, olive-toned eyes, and a work outfit of pink tees, blue coveralls, and red-white sneakers. Though authoritative, he peppers interactions with playful antics—pranking employees with fabricated shop-debt dramas to mask prioritizing personal plans like dates.
Deeply invested in his team’s welfare, he intervenes decisively when risks arise. After Reki Kyan injures himself racing rival Shadow, Oka enforces mandatory rest, redirecting delivery tasks to Langa Hasegawa. This move unintentionally steers Langa toward "S," an underground skate circuit where he competes. Later, as Reki voices fears over Langa confronting Adam, Oka proactively counsels Langa on safety protocols, supplying protective gear and outlining dangers—advice Langa politely disregards.
Beyond managerial duties, Oka mentors through vulnerability. Discovering Reki battered in an alley post-fight, he coaxes the teen’s admission of self-loathing, countering with wisdom on reconciling self-doubt, citing his own past struggles. These exchanges reveal a mentor who pairs emotional openness with pragmatic support.
His influence extends to staffing decisions, arranging Langa’s employment post-Reki’s recommendation while deferring final approval to Dope Sketch’s owner. He occasionally surfaces at skate events, observing talents like Miya Chinen and reacting with mild astonishment when elite skaters visit the shop. Though his full name stays undisclosed, his name’s kanji—岡 (ridge/hill) and 正吉 (proper/good fortune)—etymologically echo themes of steadfastness and integrity.
Through these roles, Oka emerges as a steadfast mentor who blends operational competence with compassionate guidance, safeguarding his team’s physical and emotional well-being through workplace adaptations, candid dialogues, and timely interventions in crises.
