I, Uchiha Hikaru, have joined the chat group.

Are they twins in Chapter 49?

The car Bulma brought was clearly a custom-made model, about the size of a small house.

At the front is the cockpit; in the middle is the passenger compartment, with a sofa on each side. Pulling the curtain creates a small, enclosed living room where even the ghost, Nezuko, can come out and move around; further back is a compartment containing various instruments and equipment, and at the rear is a sunroof for collecting sunlight.

After getting on the bus, Bulma finally met Nezuko. After playing with the bewildered little girl for a while, she went into the last room to prepare for spectral analysis.

The driver was Uchiha Hikaru's shadow clone.

She had at least passed her driving test in her previous life. Although cars on Earth in the 21st century are slightly different from those in the Dragon Ball world, they are not much different.

"Tanjiro, we're heading southeast next, right?"

"Oh right..."

Even now, Tanjiro is still completely bewildered, not understanding how Uchiha Hikaru went from one person to two. He was startled by the sound of the car starting, gripping the seat cushion tightly with both hands, afraid that he would be thrown out.

Tanjiro's crow was equally bewildered.

To be precise, it is "鎹鸦 (ya)".

The power levels in the Demon Slayer world aren't particularly high, but it does have some very strange creatures, such as the messenger birds that every Demon Slayer member is assigned after passing the entrance exam. These birds are not only highly intelligent, but most can also communicate with humans without difficulty, somewhat like the summoning beasts in the Naruto world.

In theory, they should know how to contact the Demon Slayer Corps headquarters.

However, Uchiha Hikaru was focused on catching demons at the moment, so he didn't interact much with Tanjiro's Kasugai Crow. Instead, he used his main body to train quietly while his shadow clone drove the car at high speed.

Halfway there.

They encountered Zenitsu Agatsuma, a blond boy who was pestering a girl to marry him.

After recognizing Tanjiro's identity as a member of the Demon Slayer Corps, Zenitsu Agatsuma also got into the car.

"...Seriously, are the Demon Slayer Corps all treated this well? They even provide members with special transportation. Is this some kind of train? It can run off-track, and it's incredibly fast!"

"By the way, I noticed earlier, are you twin sisters, Miss Uchiha and the young lady driving? You look exactly alike!"

Inside the train carriage.

Zenitsu Agatsuma also started to make a lot of noise.

Actually, this guy has seen a lot of the world; at least he wouldn't mistake a train for a "local deity" like Tanjiro did. But it's really hard for him to stay calm when faced with things that are beyond the comprehension of the Demon Slayer world.

Faced with this guy's question about "twins," Uchiha Hikaru's true form let out a soft breath and fell back into his seat from his suspended state:

"This thing is called a car, but it probably didn't exist in Japan at this time... You can think of it as a shorter train. As for me, the young lady driving, and the blue-haired girl in the room inside, we're not members of the Demon Slayer Corps; we're just Tanjiro's friends who travel with him."

"friend?"

Zenitsu Agatsuma stared wide-eyed in surprise at Tanjiro, his gaze filled with envy, jealousy, and resentment: "We're both new members of the Demon Slayer Corps, so how come you get to travel with so many beautiful girls! Oh, and you even have a super cute little sister with you... Four, a whole four girls! This kind of life is just too enviable!"

"Zenitsu-kun, you've misunderstood..."

With his collar being grabbed, Tanjiro struggled to explain, "Actually, Hikari and Bulma are both my seniors. Although they're not members of the Demon Slayer Corps, they're incredibly strong!"

"You're kidding, it looks so small..."

"It's true!"

Let's not even talk about Tanjiro and Zenitsu's constant bickering.

According to the original storyline, it would probably take them a whole day to reach the next ghost's location.

However, because they were driving, Uchiha Hikaru and his group arrived near the Demon House in just three hours.

Even with the poor road conditions, Uchiha Hikaru didn't dare drive too fast.

"Miss Hikari, Kasugai said the ghost is in that house."

Tanjiro picked up his Nichirin Blade: "Could you and Bulma please look after Nezuko for a moment? Zenitsu and I will go in and check on her."

"...You have ten minutes."

Uchiha Hikaru stretched, detaching himself from his "ki" training: "I'll go in again in ten minutes. If you haven't dealt with the demons by then, they're mine. As for Nezuko, don't worry, my shadow clones will stay here to look after her."

"it is good."

Tanjiro dragged Zenitsu, who looked very resistant, and they set off.

Only then did Uchiha Hikaru walk to the back of the RV and knock on the door.

"How's it going, Bulma?"

"...The sunlight in this world contains some special components, possibly several unknown rays. I'm analyzing their wavelengths and frequencies. Later, I might scan Tanjiro and Zenitsu's Nichirin Blades again to see which component they absorb the most, so that we can determine what the demons truly fear."

Bulma turned her head and glanced at it, explaining as she continued operating the instrument.

"Oh……"

Uchiha Hikaru glanced at the patterns on the ritual table, not wanting to disrupt Bulma's train of thought with random remarks: "Tanjiro and the others have already gone to find the demon. Give me the laser sword and protective suit you made earlier, and I'll go test their power for you."

"Hey, what about me?"

Bulma panicked a little: "What if those 'ghosts' come after you leave..."

"Demons cannot move freely during the day, and my shadow clone is right in front of us. She is half as strong as me and will protect you."

Previously, Uchiha Hikaru had tried to activate Susanoo using Shadow Clones, but failed.

—In the original storyline, Madara Uchiha was able to activate Susanoo simultaneously with 25 clones thanks to his infinite chakra from the Impure World Reincarnation technique, combined with Wood Release clones derived from Hashirama's cells. Since she doesn't meet either of those conditions now, it's normal that she can't do it.

But it's not a big problem.

Even with only half her strength and unable to activate Susanoo, Uchiha Hikaru is still one of the strongest in the Demon Slayer world. Unless all twelve demon moons arrive at once, there's a slight chance they could break through her defenses and injure Bulma and Nezuko behind her, but the probability of that happening is practically zero.

After giving a brief explanation, Uchiha Hikaru dressed himself, got out of the car, and headed towards the Demon House.
