My name is Yukino Yukinoshita.
Second-year high school student.
When I got home from school today, I stumbled upon a shocking secret about my classmate.
Nanashi Fumei.
My classmate.
Top of the class.
Ace of the sports team.
Slightly handsome.
But today, I saw a completely different side of him with my own eyes.
He shoved a thick wad of cash into the hands of a petite, fragile girl and then dragged her into a dark alley.
This was clearly illegal!
Compensated dating—it could be nothing else!
"…"
After a brief moment of hesitation, Yukino made her decision.
She couldn't just stand by and watch her classmate throw his future away.
Nor could she ignore a girl being led down a dangerous path.
Her principles wouldn't allow her to turn a blind eye and pretend nothing had happened.
"No! Ahhh!"
A sudden, piercing scream echoed from the alley.
"This is bad!"
Yukino's heart pounded as she quickened her pace, rushing toward the source of the voice.
Without thinking, she charged into the alley, panting, her voice filled with righteous fury.
"Nanashi Fumei! Stop your illegal and criminal actions at once! I've already called the police!"
"Huh?"
Nanashi turned his head, his expression unreadable.
Under the dim alley lights, his school uniform was unmistakable.
He was clearly aware of her presence.
Yet, his movements didn't stop.
Instead, he stepped in deeper.
"Ahhh!"
The girl cried out again, her voice filled with pain.
"You…!"
Yukino started to speak—only for the words to catch in her throat.
Her blood ran cold.
Because she saw it.
Nanashi's right hand was inside the girl's stomach.
No—piercing straight through it!
The girl let out a low groan.
Blood dripped to the ground.
"Y-You… k-killed her…"
She had thought this was compensated dating.
But she never expected to witness a murder right before her eyes.
Yukino's legs trembled.
She wanted to run.
Wanted to flee as far from this place as possible.
But she couldn't.
It was as if her feet were nailed to the ground.
Before she could process what was happening, the girl's weak moans suddenly transformed into something else.
"Ah… You can see me."
The girl's voice distorted.
"You can see me… I'm going to eat you!!!"
At first, she had been groaning in pain.
But in the next instant—
Her neck stretched unnaturally, snapping toward Nanashi like a snake.
Her face twisted into something monstrous.
Her mouth widened, revealing rows of jagged, bloodstained teeth.
She lunged, aiming to tear Nanashi's head off with her gaping maw.
But Nanashi didn't flinch.
His expression remained calm.
He simply raised his hand—
And then…
"Bang!"
A crisp, resounding impact echoed through the alley.
With a single slap, he sent the creature's head flying.
It crashed heavily onto the ground.
"???"
The monster's expression twisted in disbelief as it made contact with the pavement.
But it recovered quickly.
Its eerie, glowing eyes darted toward Yukino—toward the terrified girl frozen at the alley's entrance.
Yukino's entire body shuddered.
The creature's lips curled into a grotesque grin.
Its voice was shrill, erratic, filled with madness.
"You can see me, right? You can see me! You must be able to see me!!! I'm going to eat you!"
It didn't wait for Yukino's answer.
It didn't need one.
The monster had already decided.
It lunged toward her, its horrific face and bloodstained fangs closing in.
"No... Don't come any closer!!!"
Yukino's mind went blank.
Pure terror consumed her.
Her body refused to move.
She could do nothing but watch.
Feel its rancid breath against her skin.
Her heart pounded wildly, like a drum in her chest.
Her throat dried up.
She couldn't even breathe.
She was suffocating.
And then—
"Five-Elements Lightning-Dharma."
A cold voice rang out beside her.
Thick, inky-black liquid surged from Nanashi's hands.
It spread across the monster's mutilated body in an instant.
Before the creature could react—
"Zizizizi!"
Darkness crackled.
Lightning burst forth, illuminating the narrow alley in violent flashes.
The sound of electricity sizzled through the air, sharp and unforgiving.
The monster shrieked.
Its body convulsed.
And then—silence.
As the final sparks of black lightning faded, the alley returned to stillness.
The monster's body had been reduced to nothing but ashes.
Only Nanashi and Yukino remained.
"Pah."
Yukino collapsed onto the cold pavement.
Her entire body felt drained of strength.
Her eyes stared blankly ahead.
As if she had just awakened from a nightmare.
Nanashi had already approached her while she was still in a daze.
He was slightly surprised when he saw her face—pale as paper, yet still strikingly beautiful.
"Yukinoshita-san?"
Yukino slowly lifted her head, her dazed eyes shimmering with unshed tears.
"You..."
"Shh…"
Her dry throat struggled to form words.
But before she could say anything, Nanashi raised a finger to his lips, signaling her to be silent.
Without another word, he removed his black coat and draped it over her exposed thighs, shielding her legs beneath her school uniform skirt.
Then, without looking back, he walked away.
Yukino remained frozen in place, watching his retreating figure in confusion.
She didn't understand the meaning behind his actions—
Not until she tried to move and felt the dampness between her legs.
"..."
Her face instantly flushed a deep red, like a ripe apple.
A crimson hue spread from her neck to the tips of her ears.
It was wet.
Cool.
Down there.
Doomsday Chat Group! Doomsday Chat Group! I can finally recruit people!
Nanashi hurried home, his heart racing with excitement.
The Doomsday Chat Group, which had remained silent for an entire year, had finally shown signs of activity.
His Five-Elements Lightning-Dharma was a power granted by this very group.
Eighteen years ago.
Nanashi was reborn from Earth.
In this world, he assumed the identity of Nanashi Fumei, an orphan.
During elementary and junior high school, he had a classmate named Eriri Spencer Sawamura.
At first, he thought he was a typical time-travel to the ordinary daily life world—
Using knowledge from Earth to get ahead in life.
By the time he was in junior high, he had already made a fortune.
But when Nanashi entered high school, he realized something.
This world was far from ordinary.
His classmate, Yukino Yukinoshita.
The beautiful Senpai, Kasumigaoka Utaha.
The brilliant student council president, Kaguya Shinomiya.
Nanashi was shocked.
This… was an everyday anime world?!
That was the conclusion he reached.
But it didn't take long for that theory to be completely shattered.
One year ago.
He met a girl at school.
Her name was Yotsuya Miko.
That "girl who can see spirits."
From that moment on, everything changed.
Nanashi came into contact with the hidden truths of this world—
And the existence of supernatural beings.
It was also then that the Doomsday Chat Group appeared and invited him to join.
[The Doomsday Chat Group has detected that your world is approaching the apocalypse. You are invited to join. Do you agree?]
Nanashi hadn't immediately agreed.
But according to the initial description—
This was a cross-world communication platform, designed for people to resist doomsday scenarios together.
He had been selected because he had come into contact with the supernaturals.
Though he didn't know when or how the apocalypse would happen in his world.
And for the past year, he had been the only member.
The group owner had never appeared.
And without anyone else to talk to, there wasn't much of a chat group to begin with.
Still, the group itself wasn't entirely useless.
It provided several powerful features:
[Doomsday Sign-in] – Earn 1-100 Doomsday Points daily.[Doomsday Roulette] – Spend 1,000 points for a chance to acquire items or abilities from across different worlds.[Ability Enhancement] – Strengthen personal abilities using Doomsday Points.[Ability Recycling] – Convert unused abilities into points.[Ability Visualization] – Transform abilities into detailed status screens.
And today—
There was finally a new development in the chat group.
[Dear Administrator, you have been granted invitation privileges. Would you like to invite new members?]
Without hesitation, Nanashi selected [Yes].
[Group member invitation successful!][This Girl has joined the chat group!][Exusiai has joined the chat group!][The Goddess of Water has joined the chat group!][Busujima Saeko has joined the chat group!]
