the sun slowly rose over the horizon, marking the beginning of a Tuesday that promised to be like any other. Students woke up early, although most were not eager to go to school. While some prepared well in advance, even without sleeping, there were three who felt an inexplicable unease. A dark premonition told them that something was wrong. They decided that figuring it out would be best after school.Rosario dressed as always, simply but elegantly. She liked to look nice without drawing too much attention.Pato, for his part, prepared in his usual attire: a black hooded sweatshirt, brown fabric pants, and his characteristic messy hairstyle.Benjamin, however, was distracted. The unease he felt seemed related to someone he knew, and the fact that León wasn't responding to his messages only increased his worry.Benjamin: "It's strange, he never leaves his cell phone and always responds quickly. Something must have happened to him."Upon arriving at school, they immediately noticed that someone was missing. León, who always arrived before the others, was not there. León's absence went unnoticed by many, and the day continued without apparent problems. The hours felt endless until the first break bell rang. The students headed to the patio to eat, some waiting for regular classes to begin again.At noon, when the bell rang again, everyone lined up in the patio and returned to their classrooms. However, upon entering the classroom, they noticed that León was still absent. The only indication of his presence was the book he always left under his desk, now abandoned and lonely. The sight of the empty desk gave the impression that León had suddenly disappeared.Benjamin: "Where have you gone? I hope you're not doing anything dangerous."Rosario, hearing the anguish in Benjamin's voice, approached and touched his shoulder with a reassuring hand.Rosario: "Calm down, Benjamin. He's probably sick or working. He always talks about his work, so you shouldn't worry too much."Benjamin looked at her, and although his worry didn't completely disappear, he calmed down a bit. He returned to his desk and sat down, waiting for class to begin. However, when all the students were in their places, the geography class was abruptly interrupted. The classroom door burst open, hitting the wall with a crash that startled everyone.The classroom fell into an expectant silence as a young man with long, dark black hair entered the room. His hair cascaded down to the middle of his back, and his presence imposed a sense of mystery. He wore a striped leather vest, which fit perfectly to his torso and stood out against a tight black low-necked shirt. His jeans were black and military-style, complemented by completely dark and well-polished military boots. Each step he took seemed to resonate with authority as he observed each student with a penetrating gaze, evaluating and analyzing who he could consider his friends and who his victims as he smiled.The teacher, noticing the young man's late arrival, raised his voice firmly, trying to regain control of the situation.Teacher: "You're late, student. Can you tell me your name? I don't recognize you; are you new?"León looked at him with a smile that revealed an almost defiant calmness and unshakable confidence. He responded with a tranquility that surprised everyone.León: "Oh, I'm sorry, teacher. I just changed my style a bit. Is it that noticeable?" León said, laughing softly with a spark of impudence in his eyes.The teacher was speechless. He couldn't believe that this young man, who had always been known for his glasses, his simple and disheveled clothes, and his shy and reserved behavior, now appeared with such a striking appearance and spoke with such uninhibited confidence. León, who used to be almost invisible, now radiated a security and a defiant attitude that made him stand out in the room.With a mixture of disbelief and resignation, the teacher motioned for León to go to his seat so he could continue with the class. León passed by Luna, who, seeing him dressed in such a sophisticated and somewhat attractive style, decided to greet him kindly. She took his arm in a friendly gesture, but León delicately pulled away, maintaining the mocking smile he had shown the day before.León: "Don't touch me. You're probably so used that you could give me cancer and AIDS just by contact. Besides, I don't want to get my clothes dirty with hypocrisy," León said in a sarcastic tone, while exaggeratedly and disdainfully wiping the place where she had touched him.Luna froze, tears filling her eyes. The public humiliation left her speechless, unable to defend herself. While she remained silent, León went to the last seat, the one he always used to occupy. There, he greeted his friend Benjamin with energetic enthusiasm and an attitude that seemed so familiar and yet so different from the one he had shown before.The hours at school passed without notable incidents until the second recess. When all the students left the classroom, Rosario firmly grabbed León by the shirt and dragged him into an empty classroom, forcing him against the wall. Rosario, endowed with an innate ability to perceive the mystical and the occult, whether ghosts, spirits, demons, and other beings, knew that the entity in front of her was not the real León. Despite his effort to appear scared and confused, the imposter could not completely hide his true nature.Rosario: "Who are you, and why are you using this body that doesn't belong to you?" Rosario demanded in a firm and authoritative voice, looking directly into the imposter's eyes. The eyes that until that moment had simulated fear and confusion began to reveal a cruel evil. A sadistic smile slowly spread across the imposter's face as he tilted his head in a disturbing manner. With unexpected force, he grabbed both of Rosario's wrists and began to squeeze and bend them violently. Rosario, unable to endure the intense pain, weakened quickly and began to fall to her knees before the impressive force of the being inhabiting León's body.Shadow: "Look, I only pretended to be León because he asked me to, but since you've discovered me, I can only tell you the truth," said the imposter, who identified himself as Shadow, while laughing with a satisfying and evil thirst.Shadow: "I'm sorry if you cared about León, but... he'll never come back."Shadow released Rosario's wrists and, with renewed brutality, firmly grabbed her by the neck, lifting her slightly before slamming her against a nearby table. His eyes gleamed with a penetrating gaze full of perverse thoughts as he caressed Rosario's face with his fingers, moving with a cold, sadistic, and seductive tone that, despite its terrifying hue, was unsettlingly attractive."It would be a waste to kill someone like you... Maybe we should play a little first," Shadow said in a tone that mixed coldness and seduction, sending a shiver down Rosario's spine.Despite the terror she felt, Rosario tried to resist. Shadow, unwilling to lose his dominance, easily began to subdue her weakened body. However, just when it seemed that Shadow was going to force himself on her, a heavy piece of metal was thrown at great speed towards the imposter's face, hitting him squarely and causing him to fall unconscious to the ground. Benjamin, who had suspected that something was wrong, had decided to act. After hearing the conversation and waiting for the right moment, he intervened to protect Rosario.Benjamin: "Can you bring him back?" Benjamin asked firmly, looking Rosario directly in the eyes as they stood before León's unconscious body.Rosario hesitated to answer, but finally said bluntly:Rosario: "The most I can do is bring him back for a few minutes. If he wants to return, you'll have to convince him yourself."Benjamin contemplated his friend's body, thinking about how León would act if he were in his place. He knew that León, being overprotective and fearful, would have taken even more extreme measures. He felt a pang of guilt for not having been closer to him. Looking at Rosario again, he said with determination:Benjamin: "Let's do it. Bring him back. I'll convince him, even if it's by force. I'll try to convince the teachers to help us, but... if it doesn't work, we'll have to think of a plan B.
