The rhythm of their footfalls echoed against the sun-bleached concrete—a rhythmic, metallic click-clack that pulsed in time with the adrenaline fading from their veins.
Rin Kuga followed several paces behind Yamauchi Sakura. They had just slipped past the school's front gates, ghosting through the blind spots of the weary security guards with a practiced ease that felt like a minor heist. Once the heavy iron bars were safely behind them and the sanctuary of the open street lay ahead, Sakura finally released his hand.
She spun around, a bell-like peal of laughter erupting from her throat. It was a bright, defiant sound that seemed to challenge the very air around them.
Rin watched her in silence. Even in his previous life, he had known of Yamauchi Sakura—the girl whose optimism was so fierce it bordered on the grotesque, a character defined by a cheerfulness that felt like a mask forged in fire. But seeing it was different from feeling it. Standing in her presence, he could sense the strange, jagged edges of her spirit. She wasn't just cheerful; she was vibrant in a way that felt dangerously close to burning out.
Sakura caught her breath, her laughter tapering off into a wide, mischievous grin. She parted her cherry-blossom lips, her eyes scanning the young man before her.
"You know, you're a real freak, aren't you?" she teased, though her voice carried a note of genuine intrigue. "You peeked at my secret notebook, yet here you are, acting like it's the most boring thing in the world. Totally unfazed."
She tilted her head, studying his stoic expression. Rin stood like a statue, his presence heavy and cold—unusually so for a high schooler. There was a frigid detachment in his gaze that felt almost non-human, as if he were looking down at the world from a throne made of ice. And yet, that was exactly what she needed. She didn't want pity; she wanted someone who could look at her impending end without blinking.
Rin's brow furrowed slightly at the word 'freak.' He adjusted the cuff of his uniform, his voice dropping into a low, resonant baritone.
"A freak?" he repeated, a ghost of a smirk playing on his lips. "I don't think you're in any position to be judging the 'normalcy' of others, Yamauchi-san."
Sakura let out a sudden, delighted snort of laughter. "Pfft! See? Definitely a freak." She stepped forward, extending her right hand with a formal flourish. "Fine then. I'm Yamauchi Sakura. And you are?"
Rin looked at her hand for a moment. He hesitated, his mind flickering back to his brief encounter with Sumireko Sanshouin, before reaching out. His grip was firm but brief—a king granting a fleeting audience.
"Rin Kuga," he said simply.
He offered no further explanation, no polite small talk. He simply gave his name as if it were a fact of nature.
Sakura's smile twitched with a hint of annoyance at his brevity, but she didn't push it. In fact, his refusal to coddle her or treat her like a fragile glass doll was refreshing. Most people, once they glimpsed the truth of her condition, started looking at her with those 'funeral eyes.' Rin Kuga looked at her as if she were a puzzle he had already solved.
"That 'illness' of yours," Rin began, his tone shifting. The air around them seemed to grow heavy, the atmosphere tightening as he stepped into her personal space. "It's not just a physical ailment. It flares up when you're overwhelmed by negativity, doesn't it? Your body begins to turn translucent, your lungs seize, and the world starts to fade away."
Sakura froze. The blood drained from her face, her hand dropping to her side.
Her notebook hadn't gone into those specifics. In the original records of her life, it was a simple pancreatic disease. But as Rin's senses sharpened, he felt the truth. Within the girl's soul, he sensed a familiar, digitized rot—the jagged, glitching energy of the Bugster Virus.
It was a staggering realization. This world, this supposed sanctuary of slice-of-life normalcy, had been invaded by the viral pathogens of a game world. A singularity was forming, and Sakura was at the center of it.
"How..." she whispered, her voice trembling. "How could you possibly know that? Only my parents and my doctor... how?"
She stared at him, her heart hammering against her ribs like a trapped bird. This wasn't a normal student. The way he spoke, the way the very shadows seemed to lengthen behind him—he was something else entirely.
Rin shook his head, dismissing her shock with a wave of his hand.
"You should worry less about how I know, and more about the ticking clock in your chest," he said, his voice cold but tempered with a trace of tectonic fury. How dare this alien virus claim a subject of his world? "If it weren't for that unnaturally bright disposition of yours, the virus would have consumed you weeks ago. Your spirit is the only thing keeping the synchronization from reaching a terminal stage."
He caught himself, realizing his tone had veered too far into the regal, his words cutting deeper than intended. He exhaled, the pressure in the air dissipating just enough for her to breathe.
"Listen to me," Rin said, locking his eyes onto hers with an intensity that brooked no argument. "I have a way to treat it. I can cure you."
For a heartbeat, a spark of pure, radiant hope flared in Sakura's eyes. It was a blinding light, the desperate wish of a girl who wasn't ready to die. But as quickly as it appeared, it died out, replaced by a hollow, weary smile.
"That's impossible," she said softly, looking at her shoes. "I've seen the best specialists. Famous doctors from all over have tried. They all said the same thing in the end... there is no cure for what I have."
To her, the Bugster rot was a death sentence more certain than any cancer. She had already accepted her role as a ghost-in-waiting. She didn't realize she was talking to the man who held the keys to all time and every power—the one for whom 'impossible' was merely a suggestion.
