"Eh, Retsu, why are you here?" Kagome's eyes widened in surprise when she saw the familiar figure.
"Oh? This woman knows you?" Hiten raised an eyebrow, sizing Retsu up. "Could it be that you are the Inuyasha this woman was talking about?"
With that, a cruel smile appeared on his face. "No matter who you are, since you've delivered yourself to my doorstep, I'll just kill you!"
Before his voice could fade, he brandished the thunder strike blade in his hand and lunged at Retsu. Dazzling lightning erupted from the thunder strike blade, shooting towards Retsu's position.
Retsu tapped his toes and leapt backward, easily dodging the lightning strike.
At the same time, with a flick of his wrist, the samurai sword in his hand turned into an afterimage, flying out and accurately shooting toward Manten behind Hiten.
"Pfft—"
The samurai sword instantly pierced through Manten's abdomen, and dark red blood gushed out.
"Ah—!" Manten let out a shrill scream.
"Manten!" Hiten's pupils constricted. Just as he was about to turn around, he heard Retsu's cold voice: "Flying Thunder God Technique."
In the next second, Retsu's figure instantly appeared in front of Manten, his left hand accurately grasping the hilt of the samurai sword.
On the hilt, a clear black "Retsu" character rune appeared; it was the Flying Thunder God Mark he had left earlier.
A ball of pale blue Chakra flickered at the tips of Retsu's right fingers. "Five Elements Seal!" he growled softly, slamming his palm heavily onto Manten's abdomen.
"Pfft—"
Manten's body was sent flying backward by the palm strike. Retsu pulled out the samurai sword lodged in his abdomen, and blood splattered across the ground.
Black sealing runes surged from the point of contact, forming a sealing formula at Manten's dantian, firmly locking away his Demonic Power.
"My... my Demonic Power..."
Severely injured and with his Demonic Power sealed, Manten went limp and fell heavily to the ground, losing even the strength to struggle.
Because Retsu's speed was so fast, it wasn't until Manten screamed and fell that Hiten, still wearing a cruel smile, turned around, only to see his brother collapsed on the ground.
Meanwhile, Retsu had already sheathed his sword, his movements as smooth as flowing water.
"Manten!"
Hiten's pupils shrank, and he rushed toward his brother in a panic. But just as he reached out to help Manten up, Retsu's figure vanished again. "Flying Thunder God Technique!"
In the next second, he appeared between the two of them, his right leg wrapped in violent Chakra, kicking Hiten hard in the abdomen.
"Boom!"
As if struck by a giant beast, Hiten's body instantly turned into an afterimage, flying backward and plowing a ditch several dozen meters long into the ground.
Houses and walls along the way were smashed to pieces. Wood chips and masonry flew, and dust filled the air.
Retsu didn't bother with the flying Hiten and looked down at the unconscious Manten. A black Flying Thunder God Mark appeared on Manten's chest.
When he struck with the sword earlier, he had deliberately avoided Manten's vital points to keep him alive, making it easier to collect life force and shards of the shikon jewel.
He leaned over and plucked the two shards of the shikon jewel from Manten's forehead, tossing them into his ninja tool pouch, then his eyes transformed into the Mangekyo Sharingan. "Kamui!"
A spatial vortex expanded, pulling the defenseless Manten into the Kamui Dimension.
"So... so strong..."
Kagome stood frozen, completely stunned as she watched the Thunder Beast Brothers being easily defeated in just a few seconds.
Retsu's immense power left her dazed; the two demons, Hiten and Manten, had almost no power to resist him.
"Miss Kagome, don't just stand there. Come here quickly." Retsu's voice reached her, pulling her back to reality from her shock.
"The other guy isn't dead yet. Although these demons are a bit weak, their bodies are different from us humans; they're especially tough."
Kagome hurriedly ran to his side, subconsciously hiding behind him.
Although they had only met once, she could feel that this powerful man had no ill intent. Staying by his side was much safer than being near demons.
"Retsu-kun, thank you so much!" She bowed deeply to Retsu and thanked him immediately.
"You're welcome. Just call me Retsu." Retsu gave a friendly smile.
When he watched the anime in his past life, although he preferred Kikyo, he didn't dislike Kagome.
For a modern junior high school girl to achieve what she did in the story in this demon-infested world, she was already very strong and remarkable.
"Okay, Retsu. You can just call me Kagome too," Kagome said, nodding at his words.
"Damn it! I'm going to kill you! I'll definitely kill you!"
A frantic roar came from the dust. Kagome was startled and quickly hid behind Retsu, looking up.
She saw Hiten, bloodied and battered, floating in the air with two flaming objects resembling the legendary Wind Fire Wheels on his feet.
The thunder strike blade in his hand glowed with blinding lightning. He stared at them with a distorted face, his eyes full of killing intent. "I will never forgive you!"
"Heh, your strength is pitifully weak, but you're quite good at talking big." Retsu looked up, his tone carrying the signature Uchiha sarcasm. "If you can't do it, don't make a fool of yourself, trash."
"..." Kagome stood by, listening to this provocative speech and couldn't help but feel a bit awkward. This man in front of her really had a way of... "Die!"
Hiten was completely enraged, and he suddenly pointed the thunder strike blade at the two of them.
A giant ball of lightning quickly condensed at the tip of the blade, crackling with electricity. The immense Demonic Power made the surrounding air tremble.
The lightning ball whistled as it shot toward the ground. Buildings and the earth along its path were instantly shattered, with rubble and electrical sparks intertwining in a terrifying display.
"You didn't even shout the name of your move before attacking; you really have no martial ethics." Retsu calmly watched the incoming lightning ball, not forgetting to make a snide comment.
"..." Kagome, who had closed her eyes in fear, was instantly speechless upon hearing this. Most of her fear dissipated.
She opened her eyes and looked at the lethal lightning ball, curious about how Retsu would respond.
"Susanoo!"
A low shout rang out as the ocular power of the Mangekyo Sharingan surged around Retsu.
In the blink of an eye, a circle of translucent blue ribs expanded around him and Kagome, quickly forming a pale blue skeletal upper-body Susanoo, firmly protecting them both.
"Boom—!"
The lightning ball slammed into the Susanoo, and a violent explosion erupted instantly. Blinding lightning submerged the entire courtyard.
The surrounding ground was torn apart, forming a massive crater, and dust billowed into the sky.
The dust slowly cleared, revealing the skeletal Susanoo standing tall on the ground. The two people inside the Susanoo were completely unharmed.
