—Bang! !

No matter what obstructs it, with the power of a Level 4 ability user, that door has no choice but to open.

The extra character kicked the door open completely.

But what came into view was a room that seemed like another world altogether.

"this--"

Upon entering the room, even the girl, a collection of malicious elements from the Misaka Network, was stunned.

Hatsune Miku rushed in and was equally surprised.

The entire interior of the house.

They were completely enveloped by an indescribable atmosphere of oppression.

"What... exactly happened here?"

Chapter 515 A One-Man Hide-and-Seek

Hatsune Miku and the extra character slowly walked into the room.

Despite this, the eerie atmosphere still made it difficult for them to come back to their senses.

A buzzing sound came from above; it was the sound of a light bulb flickering.

In the entryway of the corridor, the lights were constantly flickering, and the room was shrouded in a gloomy atmosphere.

Even though both of them possess great abilities, they are ultimately just two girls.

Rather, it would be more accurate to say that any human being would be awestruck by the sight before them.

"Hey, I'm talking to you, Hatsune Miku."

"Huh? What's wrong...?"

Do you remember what happened when that girl named Kamishiro last spoke to you?

The two chatted as they slowly walked into the room.

During this time, Hatsune Miku quietly said "Excuse me" and planned to take off her shoes before entering the room.

"Oh dear, at this point, do you think there's any point in taking off your shoes before going inside?"

This is what the extra character said while laughing and explaining, nonchalantly rushing into the living room.

Whoa… Watching her rush into the house and touch everything, Hatsune Miku couldn’t help but shudder.

Is it really okay to touch other people's things like this?

"That's so strange."

"What's wrong?"

"Look, isn't this a mansion? Logically speaking, such a large mansion should have quite a few people, right?"

The extra individual searched the entire area but couldn't find a single person.

Every room door was closed, and the lights kept flashing. Even when I went to the kitchen and the master bedroom, I couldn't see anyone else.

The only place left to explore is the second floor.

however.

When the two of them reached the stairs on the second floor, they both stopped in their tracks.

"..."

Whether it's Hatsune Miku or individual characters from side stories.

Both girls looked toward the stairs with complicated expressions.

"Did you... sense something?"

"Ah, it's more of an instinctive reaction."

She looked up and began to look around.

Hatsune Miku also noticed that a few sparks of electricity were flickering on the chestnut-haired girl's forehead.

"It seems that Misaka's ability is slightly reacting to the environment in this house."

"Reaction refers to..."

"Misaka doesn't know what it is either, but she always feels that there is something interfering with the magnetic field here."

Although Hatsune Miku's feelings were different from those of the individuals in the side stories, she also felt as if there was something in the room.

Although both of them possess power far exceeding that of ordinary people, neither of them intends to unleash their power here without any reason.

Firstly, it was to avoid causing trouble for Yuka Kamishiro, and secondly, it was because it was already the quiet of the night, and causing widespread disturbances would only create greater chaos.

Moreover, they don't think the current situation is reasonable.

"...Let's be a little careful."

The extra characters finally put away their playful attitude.

Hatsune Miku nodded, and the two of them went up to the second floor.

squeak--

They had barely taken a step when the flashing lights behind them—

It's completely extinguished.

Click, click, click.

Click click click click click click click click click click click —

"Huh...?!"

A series of sounds kept coming from the second floor.

Hatsune Miku was startled, but the two of them still ran quickly toward the second floor.

But when they arrived on the second floor, they were completely dumbfounded.

Unlike the first floor, almost all the rooms here have their doors open.

Only one room was locked.

And it's right below that door.

Like a bloody mark left by a dragging, it was branded there.

"this…!"

"Miss Yuka?!"

Regardless, they all realized what had happened.

The two immediately rushed towards the door, attempting to open it.

But let alone unlocking it, even kicking the door with your foot didn't work at all.

This door is an ordinary wooden door; even if it were locked, it shouldn't be this thick.

But the series of clicking sounds continued to come from inside the room.

Until now.

That clicking sound continued to ring out.

"This sound, there's no mistake... it's definitely the sound of something like a knife being used to chop down a door!"

The extras, who are proficient in weapons and various torture techniques, are well aware of this.

—So it really was a home invasion attack!

"Alright, Misaka doesn't have time to play with this damn guy anymore!"

Sizzle—!! The purple electricity exploded again.

She no longer cared about the damage that a Level 4 powerhouse's electric current would cause to the room. The extra individual curled the corner of her mouth and unleashed the lightning without mercy.

A sudden burst of lightning pierced through the wooden door in front of them.

After pulling the wooden door open from both sides, a girly room comes into view.

However, the two of them had no time to appreciate the room's surroundings.

What appeared before them was a figure lying on the ground, unable to get up, his body limp in a pool of blood.

"what--!"

Hatsune Miku's eyes widened immediately.

Lying in a pool of blood was a girl with long orange hair, wearing pajamas.

"Miss Yuka!!"

Bang!! At this moment, the door on the other side of Yuka Kamishiro's room was also smashed.

No—to be precise, it was chopped up.

He was stabbed.

"what…!"

Whether it's Hatsune Miku who's still taking care of Yuka Kamishiro, or the extra characters who are standing still.

Both of them looked toward the broken door.

A figure emerged, leaving behind bloody footprints.

“Found it.”

It's a bear plush toy.

It stood upright on the floor, holding a kitchen knife, covered in blood, and looked this way.

And in the room opposite—

It was countless corpses piled up together.

Click click click click click—!!

The teddy bear holding a kitchen knife ran quickly toward the two of them.

"Hehehehehehehehehehehehehe—"

Meaningless laughter, like that of a little girl, kept emanating from the doll's body.

If that were the case for an ordinary person, it would definitely be the most terrifying aspect of their life.

however.

"—Don't move!"

Boom! An invisible explosion came from inside the doll.

The teddy bear, which had been raising a cleaver and intending to kill everyone present, was abruptly stopped in its tracks.

It couldn't move, no matter how trembling its hand was holding the cleaver, and no matter how much blood seeped out of its body.

*Zzzzt!* A purple-white current instantly enveloped it.

The extra character raised one hand, using magnetic lines to hook the kitchen knife into his hand, and clenched his other fist, wrapping the level four purple lightning around it.

"Try this!"

With a wicked smile, the girl punched the doll.

Boom——! !

The overwhelmingly powerful lightning fist, with a force capable of shattering even tempered glass, instantly sent the doll flying.

The teddy bear exploded in mid-air, and its interior, resembling internal organs, burst open along with it throughout the room.

The extra individual immediately raised its hand and manipulated lightning to intercept the ejected objects.

That was rice stained red with blood.

Because everything was stuck together inside the doll, it looked just like a bear's internal organs.

Even without its upper body, the doll that had been knocked away continued to wriggle in place—
