Minamoto no Raikou and the members of the Demon Slayer Corps only saw the evil demons invading various towns and transforming one human after another into evil demons. However, they did not know that in the darkness, not only humans and evil spirits were fighting, but evil spirits were also fighting each other. After all, night has always been the time when evil spirits attack, and humans simply do not have the extra strength to explore what is happening in other towns occupied by evil spirits when the evil spirits attack. Naturally, he would not know that in the past period of time, the camp was actually divided into two evil demon camps, Muzan Kibutsuji and Enishi Tsugumi. Shuten Douji and Ibaraki Douji were originally on the side of Muzan Kibutsuji. Whether it was the sudden attack of evil spirits on humans, or the subsequent raids on the swordsmith village and the Demon Slayer Corps base, they were all led by Shuten-douji. After all, in terms of strength, Shuten Douji is superior. And Tsugumi Yoriichi only appeared when Minamoto no Raikou unified the remaining power of mankind. It was also at this time that two camps of evil spirits appeared, allowing the human side to breathe a sigh of relief. Although the two evil demon camps were in confrontation, the actual situation was that Muzan Kibutsuji had been hiding from Yoriichi Tsugakuni's pursuit.

It can only be said that Muzan Kibutsuji, who has lived for a thousand years, has some insights into escape. He chased him for several months with the power of Yoriichi Tsugakuni, and only caught him some time ago. Shuten Douji and Ibaraki Douji naturally faced Tsukuni Yoriichi, but were defeated in an instant and chose to join the evil ghost camp with Tsukuni Yoriichi as the ghost king. According to Shuten, she only helps evil spirits. As for whether the Demon King is Muzan Kibutsuji or Yoriichi Tsugumi, it makes no difference. During this period, neither side cared about humans, and didn't even take humans seriously, which is why they were allowed to survive for so long. Just as they were preparing to concentrate their forces to destroy the last remaining humans, Shirou Emiya came into this world. "Whether it's Minamoto no Raikou, Kamado Tanjiro, Miyamoto Musashi, or those members of the Demon Slayer Corps who can use breathing techniques, they are not a threat." There is no need to say much about Minamoto no Raikou. Although in the story it was she who chopped off Shuten-doji's head, in reality, Shuten-doji was more powerful. Otherwise, Minamoto no Raikou would not have had to design a plan to use poisoned wine to make Shuten-doji drunk before chopping off his head. However, Minamoto no Raikou is now a Berserker who has caused headaches for countless people in the Holy Grail War and has the power of berserker. He also has the inherent skill of special attack against ghosts because of his own legend - the mysterious killer. However, Shuten Douji is the Assassin class that provides the weakest blessing, and even negative blessing in many cases. Although Shuten-doji's statistics are still higher than Minamoto no Raikou's even when he is an Assassin, the outcome is still uncertain if they really fight. As for the other servant, Tanjiro Kamado, he is only of second-rate level and can only use special attacks when dealing with Muzan Kibutsuji. But even so, he is no match for Muzan Kibutsuji. Although Miyamoto Musashi has the combat power of a Servant, he is no different from those members of the Demon Slayer Corps to Shuten Douji. Any existence that can be overwhelmed by numbers cannot be counted as combat power. Yes, these people are nothing to be afraid of. The real tricky one is Shirou Emiya. Even if Minamoto no Raikou was able to slaughter tens of thousands of evil spirits, he would still be restrained by such a huge number. "However, it has been so long, and the story has reached its end. It won't just sit there and watch." As he spoke these words, Shuten-doji's gaze slowly shifted towards Kibutsuji Muzan.

Chapter 2: The Winner - Miyamoto Musashi (10/) A breeze blew from the distant sky, brushing across the green lawn, causing the flowers, plants and trees to sway. On the lawn, two female warriors pointed the cold blades in their hands at each other. The distance was only three meters. Miyamoto Musashi and Minamoto Raikou stood facing each other, their eyes meeting in mid-air. The air around also seemed a little quiet at this moment. "Are you ready?" Minamoto no Raikou's eyes suddenly became sharp. At this moment, the frenzied aura called Berserker suddenly rose from Minamoto no Raikou's body. Minamoto Raimitsu suddenly broke through the air and turned into a whirlwind, rushing towards Miyamoto Musashi. The sword in his hand turned into thunder and swung forward without any mercy. "call--!" Faced with the overwhelming sword energy and astonishing momentum, Miyamoto Musashi exhaled slightly, as if he was nervous or excited. Then, instead of retreating, he advanced, his body transformed into a black shadow and rushed forward. "laugh--!" A faint sound of breaking through the air was heard. The two figures, caught in the strong wind, reduced the three-meter distance between them to zero in the blink of an eye. Then, they met suddenly. "Qiang————!" The crisp sound of steel clashing was heard. That was the sound of swords colliding with each other. In the courtyard which was not very large, two figures created a hurricane and slashed at each other. "choke----!" The pleasant sound of sword chanting kept echoing. "clang----!" The swords collided with each other again, and the collision caused a sound in the sword marks that had not yet completely disappeared. The swords are crossing. Sparks were flying.

In the small courtyard, a wonderful battle is going on. Shirou Emiya sat on the wooden floor nearby, sipping the warm tea in his hand, watching the scene in front of him without much emotion. In addition, Tanjiro Kamado, Inosuke Hashibira, Zenitsu Agatsuma, Shinobu Kocho and other members of the Demon Slayer Corps beside him were all amazed at the collision in front of them with sparks flying. Everyone in the Demon Slayer Corps naturally knows how powerful Minamoto no Raikou is. If it weren't for the existence of Shuten Douji and Ibaraki Douji, I'm afraid Minamoto no Raikou would have been able to annihilate Kibutsuji Muzan on his own. However, the two parties in confrontation were not distracted at all by the astonished looks around them. All eyes, all attention was focused on the tiny tip of the sword. "boom--!" The sound of wind and thunder rang out. Minamoto no Raimitsu, holding a katana, stomped the ground hard, and his body suddenly turned in the whirlwind. He broke the sound barrier at a speed faster than a bullet, and with an unprecedented serious expression on his face, he swung out a thunderous slash at a speed that was so fast that no one present could see clearly. There is no doubt that Minamoto no Raikou was very powerful. He eliminated many monsters such as "Shuten-doji of Oeyama", "The Big Spider of Kyoto", "The Gyu-oki of Sensō-ji Temple", and was hailed as the strongest mysterious killer in the Heian period. Everyone in the Demon Slayer Corps had seen the scene where she used the thunderous sword in her hand to easily tear apart the evil demons, and they naturally understood how powerful such a blow was. Even Tanjiro Kamado in his Servant form couldn't take it easily. However, facing the thunderous blow, Miyamoto Musashi took it completely with incredible precision. Two weeks ago, facing the attack of the Lower Moon, it was difficult to guarantee the safety of one's life. A week ago, he cut off one of Ibaraki Douji's arms simply by sheer numbers. And now, facing Minamoto Raikou's thunderous sword attack, Miyamoto Musashi deflected it with a swing as fast as a gust of wind. “Clang, clang, clang, clang——!” For a moment, the sound of swords and spears rang out continuously, accompanied by bursts of scattered sparks, echoing throughout the entire courtyard without interruption. The battle continued and the situation was constantly changing. Miyamoto Musashi gradually changed from defending more and attacking less to being able to attack and defend at the same time. Miyamoto Musashi, who is a human, is now on par with Minamoto no Raikou, who is a Servant. No---- It should be said that Miyamoto Musashi has a slight advantage! ! ! ! [Observe the enemy with your heart, and you will be sure of victory; observe the enemy with your eyes, and you will be confused and defeated. ] "Om-!" The next moment, with a slight vibration in the air, a long sword flashing with an icy arc of light cut through the space and scraped forward. “Bang——!”

There was a louder collision than any previous one. The pupils of everyone present suddenly shrank, and they simply could not believe what was happening before their eyes. Only Shirou Emiya was still holding the tea with an extremely calm look in his eyes. Minamoto no Raikou was suddenly knocked back by this blow, and his body kept sliding backwards. "boom!" The ground shattered like glass under the sudden stomping of the feet. In just a blink of an eye, Minamoto Raikou appeared in front of Miyamoto Musashi again. “Shhhhhhhhh——!” Amid the sound of the air cutting, the sword turned into violent slashing blows, like lightning and thunder, attacking like an overwhelming force. “Swish, swish, swish, swish——!” In the whistling sound of the strong wind, the two swords, one long and one short, turned into afterimages and transformed into silver flashes, covering the front like a storm. “Clang, clang, clang, clang——!” The astonishing sound of swords clashing rang out. As sparks continued to burst out, the clash of swords seemed to flash wildly, causing a scene of swords and sabers. If Minamoto no Raikou's slash is thunder, then Miyamoto Musashi's slash is fire. The encounter between thunder and fire caused an unimaginable collision. 【No mind, no self】 【No thoughts, no ideas】 "laugh--!" The sword spans time. The slashing and tearing apart the space. The thunder was shattered. “Clang—!” The heavy sound of steel colliding was like thunder, shaking the air and rolling towards the earth, causing a strong wind to blow. Minamoto no Raikou's body shook suddenly, and his feet slid hard on the ground, leaving two grooves. "call out--!" A sound piercing the atmosphere also came at this moment. All that could be seen was a flash of silver, and then a katana brushed past Minamoto no Raikou's face and stabbed heavily into the ground. The air fell into silence at this moment.

The sword that fell from the sky was the weapon that Minamoto no Raikou had been holding in his hand to cut off Shuten-doji's head - Doji-kiri Yasutsuga. A slight smile appeared on Shirou Emiya's lips as he took a sip of tea, as if he had already determined the outcome of this battle. The winner is Miyamoto Musashi. Chapter 3: Three-piece set for killing ghosts (10/) The wind blew across the lawn again.
