Naruto and the ninja only stared at him confused.
But Rias, understanding the danger, gave an order to her peerage immediately.
"Issei, Yuuto! Full guard! Now!"
Yuuto stepped forward and created a wall with his Sacred Gear, Sword Birth.
"Sword Birth!"
Countless swords emerged from the ground, creating a fence line separating the enemies from them.
Dullahan neighed as his horse's hooves struck against the ground. A surge of energy coursed through the air as he unsheathed his sword. Its blade glinted menacingly in the dim light as he lifted it above his head, ready to strike.
The devil's party gasped as they saw it, feeling threatened. However, before Dullahan could act, someone shouted and rushed toward the monster.
"Konoha Senpu!" Guy exclaimed as he spun around, his feet slamming against Dullahan's head in a series of rapid kicks.
His powerful kicks seemed to have no effect on Dullahan, though he managed to force him back. Unfortunately, he was not strong enough to knock him out of balance.
In a surprising move, Dullahan countered by swinging his sword. The blade slashed at Guy's shoulder, ripping through fabric and drawing blood. Guy winced and stumbled backwards.
Seeing the opportunity to strike again, the horseman charged towards him.
But, his momentum abruptly halted when a white-haired ninja suddenly appeared beside the horse, his hand crackled with lightning.
"Chidori!"
Without any hesitation, the white-hair ninja thrust his fist forward. An electric charge surged through the air as Kakashi struck Dullahan's body, sending electricity through the metallic armor.
The electricity caused Dullahan to scream in pain and writhe. His body convulsed and writhed as he fought to withstand the onslaught of electric shocks coursing through him.
However, it did not deter the Dullahan completely, because he broke free from Chidori's hold after a few moments. As an undead monster, he had high endurance for both physical and magical attack.
Dullahan commanded his horse to rush forward. Kakashi narrowly dodged the charge, but the horseman swiftly turned and aimed his sword at his throat.
Kakashi saw the attack coming. With incredible speed and agility, he rolled away and onto his feet. He was quick to counter-attack, and threw a few shurikens at his opponent.
The Dullahan deflected the shurikens with ease using his sword.
Then, without skipping a beat, he launched himself into a furious attack, lunging towards Kakashi with his sword held high above his head. It was as if nothing could deter him from achieving his goal, even in death.
Kakashi attempted to dodge his incoming attack. However, it was too fast and powerful, so he prepared to block it when a yellow lightning suddenly fell from the ceiling.
"Lightning!"
Boom!
Akeno's magic managed to stop Dullahan from striking. Rias then stretched her hand and used her power.
"Power of destruction!"
A beam of crimson magic was formed on her palm and traveled through the air, striking Dullahan's headless body. Its body was engulfed in darkness and disintegrated slightly.
Roaring, the Dullahan swung his sword in rage, trying to dispel the power of destruction that surrounded him.
"Oh, my!" Akeno said as she raised both hands and summoned a powerful bolt of lightning. "How strong!"
At the same time, Naruto dashed forward and called one clone. He extended his hand, and a blue light sphere materialized in the shape of a ball between his palms.
"Rasengan!"
With a great amount of energy concentrated in the form of a sphere, he attacked the monster. He thrust his palm forward with a surge of determination and determination, striking the beast with tremendous force.
A powerful blast ripped through the air and Dullahan was blown away from its horse, which neighed frantically in fright. Dullahan landed on the ground, using his sword to stop his movement.
"Even that didn't work?!" Naruto exclaimed in surprise.
All attacks they sent earlier were enough to defeat normal zombies or skeletons. Not even the Big Zombie could take that many hits. But Dullahan showed how strong it was, surviving the attacks and still standing with only a light injury.
"He is quite strong!" Neji, who came beside Naruto, muttered. "I can't see its weak points either."
"So that means we just need to attack him without stopping!" Tenten unruffled the large scroll on her back and used her jutsu. "Kai!"
Countless weapons came out of her scroll and rained on the monster. But it wasn't the end.
Using this chance, Yuuto stabbed his sword on the ground and used his Sacred Gear once again.
"Sword Birth!"
Swords started appearing on the ground, surrounding Dullahan.
Facing the countless weapons raining at him from the air and the ground, Dullahan took on a stance. His sword was covered in an eerie purple light as magical runes appeared on it.
"Oh no!"
"Everyone, fall back!"
The first one noticing the danger was Akeno and Rias, who could feel the power emanating from the sword. They immediately created barriers and walls to protect themselves.
Neji's Byakugan detected the increase of mana or what the ninja called chakra. His face paled and he shouted, "Tenten, everyone, fall back! That thing is gathering chakra!"
"Get behind me." Kakashi commanded everyone and created hand signs. His hands moved so fast that nobody could tell what he was doing.
With the last hand sign created, he put his palms on the ground and used the jutsu.
"Doton: Doryūheki."
Earth rose from the ground, forming a thick wall in front of him with four dog faces engraved on it. Everyone immediately used it as a cover and got ready for the upcoming attack.
While this happened, Dullahan swung his sword. It unleashed an arc slash attack that instantly tore everything apart. Countless weapons crumbled as the invisible power slashed them apart.
Next, the earth wall was torn apart by the power, breaking into small pieces and shattered.
"Huh, the wall!?" Kakashi's eyes widened.
The shockwaves travelled further. It sent Kakashi and everyone flying toward the wall behind them.
Crash! Thud!
Some crashed into the wall and fell to the floor, while some managed to hold their footing.
Not even the Devils' barrier could hold on against the attack. They were also blown away, although it wasn't too severe due to the distance between them.
Cain was excited and he rubbed his hand watching this exciting battle unfold in front of him. He could hardly contain his enthusiasm at the thought that his enemies were facing such an unexpected challenge.
"This is amazing." He chuckled. "Now that's what I call an epic fight! Haha, nice job, Dullahan!"
