Kenta Yoshitsune is a talented football player for the Tokyo Esperion youth academy, possessing a tall, slim, and fit physique with short black hair. He exhibits strong leadership qualities mixed with emotional intensity, though he tends to mumble in public settings. As a forward, Yoshitsune displays exceptional technical skills and ball control, adept at drawing defenders out to create space for teammates. His scoring prowess earned him the top scorer position in the Takamadonomiya U-18 Premier League just before Ashito Aoi joined Esperion. Initially on the Youth A-team, he contributed to decisive victories like a 9-0 friendly win against Tokyo Shūrin High, scoring multiple goals in subsequent practice matches against the B-team. A significant injury against Aomori Seiran High led Coach Tatsuya Fukuda to temporarily transfer Yoshitsune to the B-team for recovery. Starting against Tama Sports University High, his aggressive dribbling initially disrupted both opponents and teammates. He adapted by moderating his playstyle, eventually scoring via a wall pass with Keiji Togashi to help secure a 2-1 victory before returning to the A-team. During this period, he advised Ashito Aoi to model his development after Haruhisa Kuribayashi, noting similarities in their playstyles, contrasting Ashito's initial aspiration to emulate him. Later solidifying his role as an A-team regular starter, Yoshitsune captained the side against Kashiwa Dai Business High. Playing center-forward, he scored the opening goal and assisted the second in a 3-0 win before being substituted. His performances earned him a call-up to the U-18 Japan national team alongside Nagisa Akutsu and Eita Takasugi for matches in the Czech Republic. During this concentration, he engaged in a heated argument with Akutsu, diagnosing the defender's disrespectful behavior as stemming from self-consciousness about his performance limitations at the national level. Yoshitsune achieved promotion to Esperion’s senior team alongside Kyo Shimura and Ren Yamada, announced publicly at a press conference with Fukuda and Jun Kase. He celebrated this transition at a dinner with other senior-team-bound youth players. As a senior, he facilitated introductions for Ashito Aoi and Yuma Motoki during their temporary training stint. Yoshitsune also played in the Takanadonomiya Cup final against Ganon Osaka, assisting Yamada’s winning goal in a 1-0 victory that qualified Esperion’s Youth team for the Alkass U-18 Cup in Qatar, though age restrictions made him ineligible as a third-year. He later watched Esperion’s Youth team face Barcelona FC’s Youth in the Alkass Cup on television with Yamada and Shimura.
