"I said STOP!"  Yato shouted and realised his mana-ranked pressure on Lucas''s body who was about to swing the sword for the tenth time.


    "Aga!"


    Lucas screamed in pain as kneeled to the ground and stopped his sword art movement.


    If Lucas was right state of mind he would have noticed that his body was in a mess, not from Yato mana pressure but because of the first form of  Infernal Demonic Art, the sword of madness.


    Lucas gasped for breath, beads of sweat forming on his forehead as he struggled against the overwhelming influence of the first form of the Infernal Demonic Art. The dark red glow gradually receded, leaving behind an exhausted swordsman grappling with the aftermath of his unleashed madness.


    Yato approached his expression a mix of concern and sternness. "Lucas, the first form of the Infernal Demonic Art is not something to be taken lightly. It taps into the darker aspects of your emotions, and if not controlled, it can lead to destructive consequences."


    Lucas, still panting, managed to nod, his mind slowly regaining rity. The echoes of the past adversaries he envisioned in his frenzied state lingered in his thoughts.


    "You must learn to master these forms with discipline and restraint," Yato continued, his gaze piercing. "Your emotions are a powerful force, but they should not control you. Channel that energy purposefully, or it can consume you."


    The weight of Yato''s words settled on Lucas, a stark reminder of the responsibility that came with wielding such forbidden arts. He had glimpsed the potential of the Infernal Demonic Art, but he also understood the risks inherent in its usage.


    "I... I need to learn control," Lucas admitted, his voice reflecting a mix of determination and realization.


    Yato nodded approvingly. "Indeed. Each form of the Infernal Demonic Art demands a different aspect of control. The first form tests your mental fortitude. As you progress, remember that mastering these arts is not just about raw power but about mastering yourself."


    With a deep breath, Lucas rose from his kneeling position, the glow of madnesspletely dissipated. He sheathed the Infernal Demonic Sword, the dark weapon now a silent testament to the untamed power it held.


    "I also tell you before but to master Infernal Demonic Sword you need undying will. You must not let Infernal Demonic Sword control you, also look at your body." Yato said as he pointed towards the body of Lucas.


    Blood was leaking from all over Lucas''s body.


    "The first form of Infernal Demonic Sword [The Sword Of Madness] required an intense amount of strength in the body because each strike is stronger than before so your body also needs to be stronger than before."


    Lucas swayed on his feet, the toll of the Sword of Madness evident in the blood seeping from numerous cuts and wounds. Yato''s words echoed in his mind—the demand for undying will and the reminder that mastering the Infernal Demonic Sword required not just mental control but physical strength.


    As Lucas attempted to steady himself, a wave of dizziness overcame him. The world around him blurred the cave''s walls and Yato''s figure became indistinct shapes in his weakening vision. The pain from his injuries intensified, each heartbeat a throbbing reminder of the strain he had subjected his body to.


    Yato swiftly moved to support Lucas, realizing the severity of his disciple''s condition. "Easy, Lucas. You pushed yourself beyond your limits. Rest now; recovery is part of the training."


    Lucas, his vision flickering, struggled to maintain consciousness. The cave''s echoes seemed distant, and the sensation of cold stone against his hands became fleeting and surreal. He felt Yato''s steady presence, grounding him amid his faltering reality.


    "Remember, mastering the Infernal Demonic Art is a journey, not a sprint," Yato''s voice resonated, a reassuring anchor in the disorienting haze. "Rest and recover, for the next steps require both strength and resilience."


    With those words, Lucas sumbed to the darkness, his consciousness slipping away as the world faded into a realm of dreams and shadows. The cave, Yato''s guidance, and the weight of the forbidden sword art became distant echoes, leaving Lucas in a state of reprieve.


    In the quiet of the cave, Yato carefullyid Lucas down, examining the injuries inflicted by the first form of the Infernal Demonic Sword. The crimson stains on Lucas''s clothing bore witness to the struggle between the sword''s madness and the fragile limits of the young swordsman''s body.


    As Yato tended to Lucas''s wounds, a solemn expression crossed his face. The journey to master the forbidden arts was fraught with challenges, and this was but a glimpse of the trials ahead. The Infernal Demonic Sword, with its formidable power, demanded not only mastery but sacrifice.


    In the stillness of the cave, Yato continued his vigil over his unconscious disciple.


    "I have told him before that he shouldn''t use it because his body is not ready for this but I guess young people don''t listen that much," Yato muttered as he looked at Lucas''s unconscious body.


    "Wait a minute! I''m young too!"


    Yato eximed in surprise. Yato is 29 years old right now and in a few months, he will be 30 years old.


    "Anyway, not that it matters anymore," Yato muttered and returned his attention to Lucas.


    "I''ve done it, haven''t I?" Yato mused aloud to himself.


    Indeed, he had truly taken on a disciple, a decision he never would have envisioned making in his entire life.


    To be perfectly honest, he couldn''t understand why he chose Lucas as his disciple.


    Sure the boy was talented, maybe as much as himself, if not more, but Yato still couldn''t understand what exactly made him want to take him under his wing.


    At the start, he is protecting Lucas because Headmaster Hera asked him, He also gets to know that the world government wants to experiment on Lucas''s body, to get to know his secrets.


    He doesn''t want Lucas to go through the same experience that he had when he was a kid, maybe that''s the reason he had taken Lucas under his wing.


    But there is more than that, Yato isn''t the type of person who makes rash decisions.


    Well, whatever. It doesn''t matter now.


    Whatever the reason, one thing was certain: he was now someone''s master.


    Thinking that, Yato couldn''t help but let out another sigh, "Haa."
