On the lively streets filled with Halloween festivities, a solitary figure walked in silence.
Her long, flowing purple hair framed her strikingly beautiful face. She wore a green and white school uniform that exuded a mix of cold elegance and alluring charm. Her aura was captivating, yet it discouraged anyone from approaching.
"Is this world… so peaceful?"
The figure murmured to herself as she gazed at the bustling streets. A faint sigh escaped her lips.
"Compared to my post-apocalyptic world, this place feels like heaven."
Her words revealed a startling truth about her origins—this was no ordinary girl. From the shadows, a few bystanders secretly whispered among themselves.
"Hey, could that be her?"
"Her? Who are you talking about?"
"You know, Saeko Busujima! The swordswoman from Highschool of the Dead! The one who's so skilled her… um… assets can dodge bullets!"
"Whoa, you're right! It's her!"
The onlookers, who were clearly fans of an old classic series, grew excited, their murmurs confirming her identity.
This was Saeko Busujima, a master swordswoman from the post-apocalyptic world of Highschool of the Dead. She had once won a national kendo championship, making her a beacon of hope in her world overrun by relentless zombies.
But now, she had somehow crossed over into this peaceful world.
Saeko's cold gaze swept over the curious onlookers, her expression unreadable. She didn't understand why these strangers seemed to know her.
Suddenly, a small figure hurried toward her, clutching a notebook tightly in her arms. The girl, brimming with excitement, stopped in front of Saeko and looked up with wide, hopeful eyes.
"Hello! Are you… are you Saeko Busujima?"
The girl's voice was hesitant, yet filled with anticipation. "My name is Nanamu Eri, but you can just call me Eri. Um… could I… could I please get your autograph?"
An autograph? Saeko blinked in confusion.
"Little girl, I think you've got the wrong person. I'm not a celebrity. Why would you want my autograph?"
But Eri was resolute. "You are a celebrity! In our world, you're very famous!"
Though still puzzled, Saeko humored the girl, taking the notebook and pen. With a graceful motion, she signed her name and handed the notebook back. Eri hugged it close to her chest, beaming with joy.
Watching the girl's elated reaction, Saeko smiled faintly. "You're very happy, aren't you? Yes… living in such a peaceful world, you should be happy."
Her words carried a trace of melancholy, her thoughts drifting back to her own ravaged world. Though not one to wallow in sentiment, she couldn't help but feel moved.
Eri, noticing Saeko's moment of vulnerability, quickly tried to console her. "Don't worry, Sister Saeko! You can stay in our beautiful world now—it's very safe here!"
The little girl puffed out her chest with determination, her words full of confidence. Saeko chuckled softly at the sight.
"Is your world truly that safe?" Saeko asked skeptically.
"Of course! There are many powerful people here. As for the zombies from your world, they could never exist here!"
But just as Eri finished her confident declaration, a piercing scream shattered the festive atmosphere.
"Help!!! There's a ghost!!!"
Saeko froze. Eri turned pale.
Saeko raised an eyebrow. "Didn't you say this world was safe?"
Eri stammered, "I… I said it's safe, but… these ghosts don't belong here! Sister Saeko, we should run!"
They turned to see a throng of pale, lifeless figures marching toward them. These were no ordinary people—they moved with an unnatural, chilling precision.
Nearby, a reckless man with an axe embedded in his head decided to approach one of the figures. "Wow, your costume is amazing! Let me check if it's real."
Before he could react, the figure raised an arm and struck him. With a bang, the man flew backward like a cannonball, despite weighing over 100 kilos. The sheer force left no doubt—these were not humans.
The crowd erupted in chaos.
"Run! It's a ghost!"
"Real ghosts! They're real!"
"Wait, are these the ghosts from Demon Slayer? Or maybe Natsume's Book of Friends? Or even Nurarihyon no Mago?"
"Who cares! Just run, unless you want to find out!"
