Kamihara Tetsuya's eyes narrowed; Pei Lang was a very rare demon who used firearms in combat.
He had once been cornered by the drunken Flame Pillar, Rengoku Shinjuro, but had luckily escaped with his life.
Later, after becoming a Twelve Kizuki, he set up bombs in Tokyo Prefecture to draw out the Demon Slayer Corps for revenge, and was ultimately used as a stepping stone by Rengoku Kyoujurou to be promoted to Flame Pillar.
"Why are you shooting at me?" Kamihara Tetsuya asked coldly. He wasn't wearing a Demon Slayer Corps uniform.
Pei Lang said maniacally, "No special reason, your luck just ran out."
Kamihara Tetsuya's expression darkened. He was seeking death!
Just then, Kamihara Tetsuya sharply heard a rapid series of footsteps. It was Rengoku Kyoujurou; he had also been drawn by the gunshots and had pursued them here.
The wounds on his face, inflicted by Pei Lang, were recovering. If they were seen, his demon constitution would be exposed.
Wait a minute!
Kamihara Tetsuya had almost forgotten about the skin he had opened from the Silver Treasure Chest.
Crimson Moon: Yasuo!
Kamihara Tetsuya's mind stirred, and he equipped the skin.
Boom!
At that instant, Kamihara Tetsuya's body erupted with dazzling crimson light, emitting an indescribable pressure. Pei Lang's pupils contracted, and he instinctively retreated.
Under the illumination of this crimson light, the night seemed to deepen even further.
A rich smell of blood spread, and two surging rivers of blood, like two giant dragons, spiraled skyward with Kamihara Tetsuya at their center, letting out earth-shattering roars.
"What is that?"
Rengoku Kyoujurou, who was still on another street, looked up at the crimson pillar of light that shot into the sky, a look of shock on his face. Is it a Blood Demon Art of a demon? The commotion is too great!
People three or four kilometers away can probably see it!
Rengoku Kyoujurou's heart sank. He had never heard of it before. Could it be an Upper Moon?
A Kasugai Crow spread its wings and flew high, sending out the message.
Rengoku Kyoujurou resolutely pressed forward again. Even if it was an Upper Moon, he had to stop it!
Speaking of which, the dazzling crimson light dissipated, and Kamihara Tetsuya's current appearance emerged in Pei Lang's eyes.
He was dressed like a samurai, wearing light armor, with a white demon mask on his face, blood-red eyes, a nichirin blade at his waist, and long red hair tied into a high ponytail at the back.
A Crimson Moon appeared behind him, with white aura swirling around, creating an eerie and evil atmosphere.
The intimidating power of the Crimson Moon skin felt like a great mountain pressing down on Pei Lang's head, and an inexplicable sense of fear rose spontaneously within him.
From the other party's body, he felt neither the aura of a human nor the aura of a demon; it was a more evil and mysterious existence.
Kamihara Tetsuya felt a bit speechless. The skin was indeed just a skin; all flash and no substance. Behind the dazzling and eerie phenomenon, his power hadn't increased at all.
This skin also changed the form of his nichirin blade, transforming it into a long samurai sword.
Rengoku Kyoujurou rushed out from the alley.
A normal person's gaze would be drawn to that crimson samurai. He gasped, "What in the world is that? Why do I feel such fear?"
Then, he saw another demon, and the engraving in its eyes read Lower Moon Two!
His gaze quickly searched the surroundings, but he didn't see Kamihara Tetsuya, and there was no blood on the ground. Kyoujurou breathed a sigh of relief; it seemed Kamihara Tetsuya hadn't arrived yet.
A crimson samurai who looked difficult to deal with, and a Lower Moon Two. If Kamihara Tetsuya had encountered them, he probably wouldn't be able to see him anymore.
Rengoku Kyoujurou saw Pei Lang, and Pei Lang naturally saw him too.
"Rengoku Shinjuro!"
Pei Lang's pupils reflected Rengoku Kyoujurou's reddish-yellow hair and prominent sword-like eyebrows. His eyes were bloodshot and filled with murderous intent.
Rengoku Kyoujurou frowned. It was his father's name. Had this demon encountered his father before?
It seemed the other party had mistaken him for someone else.
He didn't believe his father would have any connection with a demon, and the other party clearly showed murderous intent, so there was no need to say more; he would cut him down!
"One against two? No matter!"
Rengoku Kyoujurou and Pei Lang thought to themselves.
The Crimson Moon's set effect made him look anything but good. Rengoku Kyoujurou subconsciously assumed the crimson samurai was a demon. Because Kamihara Tetsuya had previously used Flame Breathing sword techniques, Pei Lang assumed he was a demon slayer.
"Flame Breathing: First Form: Unknowing Fire!"
Rengoku Kyoujurou took a deep breath and charged at Pei Lang with a burst of flame-like momentum. His figure was like fire, surging forth and causing space to vibrate.
"Heh heh!"
Pei Lang saw Rengoku Kyoujurou's sword technique and a sinister grin appeared on his face. There would be no mistake this time!
"Blood Demon Art: Shadow Wolf!"
Pei Lang said sinisterly, and the shadow beneath his feet suddenly split, forming five snarling, clawing wolves.
Bang! Bang! Bang!
The wolves opened their mouths wide, revealing dark, hollow muzzles. Immediately after, tongues of fire spat out, and dense bullets shot towards Rengoku Kyoujurou and Kamihara Tetsuya.
The moment Rengoku Kyoujurou saw the muzzles, he sensed something was wrong. He moved his right foot, changed his route, and dodged the incoming bullets with an S-shaped movement.
Blood Demon Art: Whimsical Metamorphosis!
Kamihara Tetsuya raised his left hand, transforming it into a steel shield emitting a dark, gloomy light, blocking the bullets.
The impact of the bullets caused his body to recoil.
Kamihara Tetsuya lowered his head in thought. The caliber of the firearms Pei Lang was using wasn't very large. The hardness of the Whimsical Metamorphosis shield wasn't very good; it would break in at most ten more seconds.
However, Pei Lang's target was clearly not him.
"Play with me more happily!"
Pei Lang laughed maniacally, continuously pulling out explosives and Molotov cocktails from his body and throwing them at Rengoku Kyoujurou.
Boom! Boom! Boom!
Continuous explosions shattered the night's tranquility. Fierce flames burned, and firelight soared into the sky.
Rengoku Kyoujurou couldn't get close at all and was completely bewildered. Most demons were overly confident in their powerful physiques and disdained using weapons, but Pei Lang was ahead of his time, using firearms with ease.
Bang! Bang! Bang!
Pei Lang pulled out a Gatling gun and sprayed Rengoku Kyoujurou, the sound echoing through the sky.
Facing the rain of bullets, Rengoku Kyoujurou's scalp tingled. Not daring to stay in the open, he immediately rushed into the small grove of trees planted in the nearby park.
The dense bullets shattered the trees, and Rengoku Kyoujurou could only keep moving.
Suddenly, Rengoku Kyoujurou felt something tightly bind his right leg.
"Oh no!"
The small grove allowed him to dodge Pei Lang's shots, but it also limited his vision. When he realized this, Rengoku Kyoujurou immediately felt a sense of foreboding.
Kamihara Tetsuya watched the battle unfolding in front of him.
Rengoku Kyoujurou's slaying of Pei Lang happened after he became a Kinoe-ranked swordsman and took Kanroji Mitsuri as his "Tsuguko," at around eighteen or nineteen years old.
However, the current Rengoku Kyoujurou was only sixteen. Because of him and Tamayo, Kibutsuji Muzan sent a Lower Moon to investigate, leading to an early encounter with Pei Lang, putting him under even greater pressure.
