Chapter 39 of Blue Lock opens with a striking visual: a mysterious woman lounging with a soccer ball nearby, her cheek marked with the words “Blue Lock.” This provocative image sets the tone for a chapter that shifts away from direct competition and plunges the players into a grueling phase of physical transformation. The second selection round is not beginning immediately, much to the frustration of the players. Instead, they are informed that a mandatory waiting period will be filled with intense strength training. Anyone who refuses to participate or breaks the rules, such as touching a soccer ball, will be expelled.
The announcement sparks confusion and outrage among the players, especially those who advanced from the lowest ranked wing. Their complaints are met with harsh reprimands, reminding them of their inferior status and the need to earn their place through humility and hard work. The training schedule is brutal: endurance runs, core workouts, weight training, and sprints dominate their days, leaving them physically and mentally drained. The players struggle to keep up, some collapsing mid sprint, others barely able to eat. Isagi, among them, pushes through the exhaustion, supported by teammates who share water and encouragement, reinforcing the camaraderie forged through shared suffering.
As the days stretch from four to nine, the toll becomes evident. Legs ache, spirits waver, and doubts creep in. Isagi questions the purpose of the training, wondering if it will ever end or if it’s even meaningful. Yet beneath the fatigue, a quiet resolve begins to build. The players endure, driven by the hunger to improve and the fear of being left behind. On day ten, the tension finally breaks with a loud morning announcement: the first selection round has officially concluded for all wings.
The chapter ends with a surge of energy and emotion. Players leap from their beds, don their training suits, and prepare to enter the underground central area for the second stage. The revelation that they can finally touch a soccer ball again reignites their passion. Isagi, teary eyed and overwhelmed, feels reborn. The second selection round is about to begin, and with it, a new chance to prove their worth.
