Keisuke Wanima is an 18-year-old male standing 182 cm tall, with dark brown eyes and short black hair shaved into a distinctive draconic or crocodile-like pattern on the sides, sometimes colored green in adaptations. He frequently sports a wide, toothy grin. He shares an August 20th birthday and blood type A with his twin brother, Junichi Wanima, making their zodiac sign Leo. Known as one of the "double aces of Rajitsu Tech" or "Wanjitsu Twin Pillars," Keisuke and Junichi were regular players at their Kagoshima high school until Hyoma Chigiri joined. Chigiri's exceptional speed quickly made him the team's top player, displacing the twins and breeding resentment, especially after Chigiri suffered an ACL injury. During Chigiri's recovery, Keisuke mocked his cautious play, taunting him about his "glass knee" and fear of reinjury. At Blue Lock, Keisuke was part of Team W with Junichi. Their primary weapon was "Eye Contact," a synergistic ability enabling non-verbal coordination, with Keisuke acting as Junichi's spokesperson. This made them effective together but vulnerable apart. In Team W's match against Team Z, Keisuke immediately recognized and provoked Chigiri, referencing their history and the injury. The twins exploited a betrayal by Team Z's Kuon, who leaked strategies, allowing Team W to rally from a 3-0 deficit. Despite this, Chigiri overcame Keisuke's taunts to score a critical goal, forcing a 4-4 draw. Keisuke's personality orbits entirely around his bond with Junichi. He is highly attuned to Junichi's non-verbal cues, prioritizing their connection above all else and paying little attention to others. Off-field, he shows playful loyalty, enjoying simple pleasures like cloud-watching or McDonald's shakes, and practices facial muscle exercises to better communicate with Junichi. Yet, he displays cruelty when threatened, evident in his relentless mocking of Chigiri's vulnerability. He is pragmatic and competitive, readily accepting underhanded tactics like Kuon's betrayal for advantage. Team W placed third in their First Selection group, leading to the elimination of all members except top scorer Junichi. Keisuke was eliminated. During his emotional departure, he tearfully wished Junichi success and joked about becoming a "mimic comedian" impersonating his brother under the stage name "Keisuke Davidson." Keisuke comes from a family with parents and two younger brothers. He began playing soccer at age three alongside Junichi and favors Italian player Giacomo Raspadori. He prefers animal biscuits and katsuo miso with rice but dislikes celery and salmon roe. He enjoys the *Detective Conan* franchise and the manga *Ashita no Joe*. His personal motto is "Combination is beautiful." If given 100 million yen, he would give it all to Junichi. On his last day on Earth, he would play soccer with his brother.
