Asahi Naruhaya, a former Blue Lock participant originally on Team Z, stands 168 cm with a notably small build for soccer. His appearance features fluffy blonde hair, darker round eyebrows, and long eyelashes. Naruhaya blends kindness and responsibility with a mischievous streak. He demonstrates care through actions like relentlessly searching for Gagamaru's lost hair tie and supporting his family as one of the eldest siblings, a responsibility driving his soccer goals. He often acts as Team Z's jokester, engaging in playful antics like stealing food. Possessing significant self-awareness, he openly tells Isagi Yoichi they are ordinary players compared to prodigies like Seishiro Nagi, Shoei Barou, or Meguru Bachira, a realism shaping his competitive approach. His identified soccer weapon during the First Selection is exceptional off-the-ball movement. He describes this ability as letting him "fly across the pitch," surpassing Isagi at that stage. It involves strategic positioning to disrupt defenses, precise timing, and exploiting opponents' blind spots to create scoring chances. Naruhaya plays in all Team Z's First Selection matches. Key contributions include operating as a forward against Team W, where drawing a foul leads to a free-kick goal, and defensive efforts like marking opponents versus Team V and attempting to block Nagi's shots. He survives to advance into the Second Selection. There, he partners with Shoei Barou for a critical 2v2 match against Isagi and Nagi. Before it starts, he articulates the stakes to Isagi: "Let’s beat each other up, Isagi. Put both of our dreams on the line. Don’t get scared, we’re at ‘Blue Lock.’" During the match, his strategic movements and passes are hindered by Barou's refusal to cooperate and selfish play. Following their loss, Naruhaya is eliminated. He expresses feelings of powerlessness alongside relief, having recognized his limitations in pursuing the "naïve and stupid dream" of becoming the world's best striker. Despite this, he feels satisfaction at reaching the Second Selection. In his departure, he wishes Isagi success, urging him to "keep winning," his final moments reflecting his pragmatism and supportive nature.
