Kai Tamsin sat at his desk, flipping through his history textbook with the kind of absent-mindedness that came from knowing he'd be tested on it later, but not really caring right now. The rain pattered gently against his window, and his thoughts drifted to the usual: schoolwork, classmates, the never-ending cycle of assignments, and the relentless march toward another day of boredom. Nothing out of the ordinary.
Except for that feeling that gnawed at him. It was the sensation that something was off, like the world was about to change—and he wasn't ready for it. The kind of feeling you get when a storm is brewing, but you can't see the clouds.
Then, the air in the room shifted.
It happened so quickly, he almost missed it. One second, the room was still and quiet. The next, there was a strange pressure in the air, something he couldn't put his finger on. Kai stiffened. He glanced around, but everything seemed normal. That was, until his eyes landed on the figure sitting at the foot of his bed.
A boy. A weird-ass boy.
His first thought was that someone had broken in, but the look of the figure made him hesitate. Silver hair. Piercing golden eyes that almost seemed to glow. The boy was dressed in a dark outfit that didn't quite look like anything Kai had seen before—strange markings across his clothes, like some kind of ancient armor, though it wasn't quite that. The boy was just... there.
"Who the hell are you?" Kai's heart leapt into his throat as he instinctively pushed himself back against his desk.
The boy didn't even blink. His golden eyes simply met Kai's, studying him with an almost detached air.
"I'm Zayn," he said slowly, his voice oddly calm for someone who had just appeared out of nowhere. "And I'm your Mamodo."
Kai stared blankly for a beat, the confusion only growing. "Zayn? Your name is Zayn? You just... appear in my room like this? Are you some kind of prankster?"
Zayn's lips didn't twitch. He didn't look surprised, or even particularly interested in Kai's confusion. "No prank. I'm a Mamodo. And you're my partner."
"Wait—hold on." Kai's mind started whirring, trying to process what was happening. He glanced at the book still sitting on his desk, the one he'd barely paid attention to. The weird glowing symbols had caught his eye earlier, but he'd dismissed them as nothing important. But now... now everything felt off. "A Mamodo? What's that? Is this some sort of weird internet scam? Are you trying to sell me something?"
Zayn didn't even blink. His eyes just stared back at Kai, intense and unyielding. "A Mamodo is a demon. And you are my human partner in the tournament."
Kai blinked, arms crossed tightly. "A tournament? Demon kings? Dude, if this is some lame fantasy story you're trying to sell, I'm not buying it. I've got better things to do than—"
"If you don't take this seriously," Zayn cut in, his voice turning cold, "you'll regret it. This is no game. This is a fight for survival."
Kai shot him a sharp look. "A fight? What the hell does that mean? And what happens if I just... ignore this? Tell you to get lost and go home?"
Zayn's golden eyes gleamed with an unsettling intensity. "If you don't fight, if you don't cast the spells, we lose. And when we lose, we die. Simple as that."
The words hit Kai like a punch to the gut. He blinked, unable to process it. "Wait, hold up—die? You're telling me I'm stuck in some life-or-death competition with a demon I don't even know? And if I don't do what you want, we both die?"
Zayn's gaze didn't waver. "Yes. That's how this works."
Kai took a step back, suddenly feeling the weight of the situation crash down on him. His mind raced with disbelief. "This is insane. I didn't sign up for any of this. I don't even know how to use this stupid book!"
Zayn's lips barely twitched, like he was holding back some unspoken frustration. "That's why I'm here. To teach you. But don't think this will be easy. If you want to survive, you'll have to fight. You'll have to grow stronger."
"Yeah, well, good luck with that," Kai muttered. "Because I'm not exactly built for fighting. I'm barely getting by in school, and now you're telling me I'm supposed to become some kind of magic fighter?"
Zayn's eyes hardened. "You'll learn. You don't have a choice anymore."
Kai's hands clenched into fists, his heart pounding in his chest. He was caught. This wasn't some random nightmare. This was real. He could feel the weight of it—the sense that his life had just been irrevocably altered. The storm outside had nothing on the storm brewing in his chest.
"Fine," Kai said, his voice low and resigned, though there was no trace of agreement in it. "Let's just get this over with then. Teach me how to fight, or whatever it is you want me to do."
Zayn nodded, the ghost of a smile on his lips. "Good. It's a start."
The next morning, everything seemed... normal again. Too normal. The rain had stopped, the sky was clear, and Kai found himself staring at his alarm clock, groggily realizing he'd overslept. He didn't have time to dwell on the madness of last night; he had school, and no amount of weird magical nonsense was going to stop him from being late again.
Downstairs, the sound of his mom's voice echoed through the house. "Kai! You're going to be late!"
Kai dragged himself out of bed and trudged downstairs, half-dressed and still trying to shake off the weirdness from the night before. His mom, busy as always, was standing in the kitchen, coffee cup in hand, wearing her usual surgical scrubs. She was a trauma surgeon, always rushing off to one emergency or another, but somehow managing to check in on him every morning, despite her chaotic schedule.
"Kai," she said, sounding a bit too calm for someone who knew how much of a wreck her son could be in the mornings. "You okay? You look... off."
"I'm fine," he muttered, still not fully present. "Just tired. Stayed up too late."
His younger sister, Maddy, shot him a look from the breakfast table. "You always look tired, Kai," she teased. "But hey, maybe if you spent less time zoning out and more time studying, you wouldn't be falling behind so much."
Kai rolled his eyes. "I'm not falling behind. I just don't care."
His mom raised an eyebrow, setting her cup down with a faint clink. "You should care, Kai. You're smart—way smarter than you let on. I don't know what's going on with you lately, but I'm worried. You don't talk about school, you don't hang out with anyone, and you're always in here, staring at that... that book of yours." She nodded toward the desk where the grimoire Zayn had left was still sitting, half-hidden beneath his clutter.
Kai's stomach turned. His mom had no idea what was really going on. How could he explain any of this to her? She'd think he was losing it. So, instead, he just mumbled, "I'll be fine, Mom. I just don't feel like talking right now."
"Alright, but if you ever need to talk, I'm here," she said, her tone softening as she gave him a brief but concerned look.
"Yeah, yeah," Kai muttered, grabbing his backpack. "I'm going to be late."
School was... school. The same old grind. Kai barely paid attention in class, his mind drifting between trying to stay awake and the nightmare of having a Mamodo partner who was threatening to drag him into some insane tournament. But it wasn't just that. It was the growing weight in his chest—the exhaustion, the pressure.
"Hey, Kai," a voice interrupted his daydreaming. He looked up to see Jake, his best friend, leaning on his desk. "You look like crap, man. Everything okay?"
"Yeah," Kai muttered, forcing a half-smile. "Just tired."
Jake frowned. "You're always tired. I swear, you're going to burn yourself out."
Kai shrugged, uninterested. "I'm fine. Just school stuff."
Later that day, as he trudged through yet another boring history lesson, his mind kept returning to Zayn and the weirdness he was now trapped in. It felt impossible. No way could this be real.
But somewhere deep down, Kai knew: his life had already changed. And no amount of school or his mom's concerned looks could stop what was coming next.
