Laser Sword and Protective Suit

Laser Sword and Protective Suit

She pushed open the door, entered the room, and shut it behind her.

The surrounding light immediately dimmed.

Uchiha Hikari looked around but did not see Tanjiro and the others who had entered earlier. She lifted her feet and walked forward on her own, randomly opening several doors along the way. In one of the rooms, she heard rustling coming from beneath a cabinet not far away.

A demon with an extremely long tongue crouched there on all fours, drooling as it stared at her.

Whoosh—

With a sharp gust of wind, the demon shot out its tongue, which tore through the air toward Uchiha Hikari's face!

At the critical moment, Uchiha Hikari tilted her head aside. With a flick of her hand, she threw out a string of Shuriken, which rang out with a series of clatters as they pinned the tongue to a wooden board nearby.

The long-tongued demon yanked hard and pulled its tongue back. As blood dripped down, the wounds left by the Shuriken rapidly healed.

Meanwhile.

Uchiha Hikari brushed her right hand across her waist, pulling a Laser Sword shaped like a flashlight from her pocket, then pressed the switch.

A pale purple blade of light, two or three meters long, extended outward and faintly illuminated the space around her.

Then...

Slash—!

As the long-tongued demon pounced again, Uchiha Hikari flicked her wrist. The purple laser carved a huge arc through the air before drawing back into a single point.

"...It didn't work?"

Uchiha Hikari frowned slightly.

But the next second.

The long-tongued demon suddenly rolled across the floor and let out a hoarse scream. The tongue dangling from its mouth split in two at the middle. No blood flowed from the severed edge; instead, a ring of charred black marks appeared there. The scent of roasted meat spread through the air, making Uchiha Hikari's nose twitch twice.

"So there's a delay..."

"Judging by the cut, does the Laser Sword inhibit wound healing?"

With a demon's regenerative abilities, losing a tongue was not a serious injury. It could grow back very quickly.

However, the wound on this demon seemed to have been slowed by that strike. Not only had the ring of charred marks on its tongue yet to fade, but the small buds of new flesh growing from either side also looked somewhat off in color.

"Brat, what did you do to me..."

The long-tongued demon let out a pain-filled roar, then scrambled forward on all fours like a gecko leaping at its prey.

This time, Uchiha Hikari charged straight at it. In the instant their figures crossed, three or four arcs of light flared almost simultaneously!

"Hiss..."

As the pale purple arcs vanished, Uchiha Hikari appeared in a corner of the room several meters away, holding a Laser Sword in each hand. She spun them once and turned around. Ignoring the surroundings, she looked like a modern girl holding glow sticks and about to attend a party.

Behind her.

The long-tongued demon screamed again. Its head, both arms, and left leg fell separately to the floor with several thuds. The remaining half of its body, stripped of head and limbs, still tried to turn and lunge forward, only for Uchiha Hikari to casually kick it away. It rolled into a ball across the floor.

At that moment, the long-tongued demon was in a very awkward state.

It was not dead.

But its wounds showed no signs of healing either.

Its body, cut into several pieces by the Laser Sword, began acting separately. Its hands crawled toward the door, its left leg ran toward the window, while its head and torso rolled about the room, emitting agonized shrieks.

"Just like before, wounds severed by the Laser Sword are cauterized after roughly one second, and the healing rate almost comes to a standstill...

"This effect is somewhat like Sun Breathing. It causes demons intense pain and temporarily deprives them of their regenerative abilities. Perhaps because it lacks those special rays from the Demon Slayer World, it can't kill instantly like a Nichirin Blade?"

Uchiha Hikari carefully observed the long-tongued demon's condition, then slashed several more times, cutting it into even smaller pieces. Only after its head had also been divided into five or six chunks did it finally let out a mournful cry and begin turning into ash bit by bit.

Only then did Uchiha Hikari switch off the Laser Swords and tuck them back into her pockets.

If the problem really was insufficient light components, it should not be difficult for Bulma to solve. She only needed to add those rays to the Laser Sword from the Dragon Ball World and modify it into a Demon Slayer World version. There should be no technical issue; it would just take some time.

"Let's try Solar Flare too..."

Uchiha Hikari carefully put on her goggles, then pressed the switch on the Protective Suit.

In an instant.

A blinding radiance like the sun erupted, turning her entire body into a little being of light and sweeping away all darkness in the room.

She could not be bothered to keep wandering through this labyrinthine house, so she simply activated the first stage of Susanoo. Wrapped in a dark red skeleton, she charged recklessly to the end of the corridor, then crashed into the ceiling above!

"Ah! My eyes!"

"What is that glowing thing? It's so bright..."

"I'm going blind..."

Several voices rang out from the floor above.

Under the intense light, neither humans nor demons could open their eyes.

Only Uchiha Hikari, protected by her goggles, could vaguely make out her surroundings. Taking this opportunity, she approached the demon with several waist drums growing from his body and gently pressed her hand, already formed into seals, against his back. "Self-Exerting Curse Binding Seal!"

This demon, Kyougai, was actually fairly strong. He had once been Lower Rank Six, the last seat of the Twelve Kizuki.

However, because he had been blinded by the intense light from the start, his movements had become extremely sluggish. Just as he tried to dodge, he was firmly bound by the curse seal.

Then Uchiha Hikari smoothly sealed him into a scroll as well.

Unlike the Laser Sword, the Protective Suit consisted mostly of visible light, with only a small proportion of ultraviolet and infrared rays.

—That was inevitable. Ultraviolet rays, gamma rays, X-rays... all of them could inflict powerful radiation on the human body. Once their intensity reached a certain threshold, they could kill large numbers of cells in a human body within a very short time. If the Protective Suit had the same components as the Laser Sword, even Uchiha Hikari, the one wearing it, would not be spared. It simply could not be used normally.

Judging from the current results...

"Purely intense light does not deal any substantial damage to demons, but it seems to slow their movements. It can buy time to attack or escape. The downside is mainly that it affects allies?"

Only then did Uchiha Hikari notice that Tanjiro, Agatsuma Zenitsu, and several human boys who had been captured were among the people who had cried out earlier.

From the moment she smashed through the ceiling to the moment she sealed Kyougai, less than a minute had passed.

But it took Tanjiro and the others more than ten minutes to gradually regain their sight.

"Eh, Miss Hikari, when did you get here? That demon just now..." Tanjiro rubbed his eyes and nervously looked around.

"It's already been dealt with."
