As Mukuro looked around, he saw who he was up against. A curse using Fushiguro Megumi's body, Mahito, Fumeiyo Seigi of the Fumeiyo clan (another member of the four families), and finally Naoya. He was outnumbered, yet he didn't have the slightest hint of fear. Seeing this, Mahito was the first to step up.

"This middle aged man is quite the eyesore. Maybe I should turn him into a caterpilla-"

Before Mahito finished his sentence, he was suddenly sent crashing into the wall as Mukuro had already slammed his fist into the cursed spirit's face. Seeing this, Seigi was going to jump in to assist Mahito. However, the young man was stopped by Kenjaku as he had a smile on his face.

"You shouldn't get involved, Fumeiyo Seigi. After all, this body still remembers it, the cursed technique of Mukuro."

Just as Kenjaku said this, Mukuro was seen dashing towards Mahito with great speed. Seeing this, Mahito lunged towards the man as he used Idle Transfiguration to fuse two souls of his many transfigured victims. This caused a negative reaction due to the two souls rejecting the fusion, however Mahito increased the cursed energy he put into it as he directs the output towards Mukuro.

"Body Repel."

"I see."

Instead of trying to dodge or block the attack, Mukuro reached into his right sleeve and revealed two humans that were transfigured by Mahito. The moment he slammed Mahito in the wall earlier, Mukuro reached into the curse's pocket to retrieve them.

"Considering humans are essentially dead when you transfigure them, I guess I can experiement a bit. Tell me, is this how you do it? Body Repel."

Mahito's eyes widen in shock with what happened next. Just seconds before his attack reached Mukuro, the Zenin had already merged the two souls together and increased the cursed energy he poured into them which caused a negative reaction. Shortly after, Mukuro directed the output towards Mahito's attack. The moment the two attacked collided, Mukuro's manage to rip through Mahito's as the cursed spirit felt the full force of the attack.

"Impossible........that was.....my Idle Transfiguration."

"Doppelganger. When info of a cursed technique, magic, or even an unknown attack that I lack is entered inside my brain......by sending a set amount of cursed energy to my brain, i can copy that trait and use it for myself. The downside is that it scales to my own strength. A weak spell becomes powerful, and a powerful spell might be lacking to the original. However, there is a way to use Doppelganger even without gaining info. If I share blood with the person I copy, the cursed technique automatically registers itself to my brain and I can use it at its maximum potential. Normally I can't perfectly copy someone, unless I reveal this technique via a binding vow."

As Mukuro said this, he began to put his hands together as the shadows around his feet began to swirl around him. Soon the Zenin head clapped his hands together to imitate the shape of wings. With an angry look on his face, Mukuro saw Mahito charging towards.

"Tell me, who's bloodline is coursing through the body of Megumi Fushiguro. Doppelganger, Fushiguro Megumi, Ten Shadows:Nue."

The moment Mukuro said this, Mahito and his allies were all screaming in pain as they were suddenly shot with a high voltage of electricity. Just outside of the temple, a large creature could be seen sitting on top of it. It was a large Owl-like creature with orange feathers and a white mask-like face. It has large wings, two sets of talons and human-like teeth.

"This is the Shikigami that Fushiguro Megumi use to fight with back when he was alive....."

"Why you...."

Suddenly Mahito used his cursed technique to turn his right arm into three sections of chains. The cursed spirit began to wildly slash at the Zenin clan head, yet Mukuro didn't even seem the least bit concerned. Just before the chains could hit him, Mukuro saw the chains suddenly get torn to shreds. However, Mahito was the most surprised out of everyone.

"Wind? But we're indoors, not only that, the last attack hit all of us. This man is on a completely different level than Megumi and Shiki."

"Did you think you could beat me because you gave Hayasaka Megumi and Koritsu Shiki a hard time? As part of the new generation, I will admit they have potential. But surely you feel it. The gap in power between their generation and my own."

As Mukuro said this, the wind surrounding him began to blow more fiercely as everyone in the building found it hard to keep their eyes open. When Mahito looked at Mukuro, he was astonished by what he saw. The shape of Mukuro's soul, it began to take shape of a man with white hair and piercing green eyes that resembled Shiki.

"Perfect Copy Doppelganger , Koritsu Ayumu, Fujin's Descent. Now then, let me be the first to show you why I am the head of the Zenin clan, cursed spirit."

~Meanwhile~
As he was walking through the night along with his son, Ayumu was taking Shiki to the outskirts of Sendai. While he was doing this, Ayumu decided that it was no time to keep secrets. Right now, Shiki needs to know the truth if he wants to survive with the life he has living now.

"Long ago, there was a family that use to be considered the trump card of the Demon Hunter Organization known as the Nanaya clan. While they possessed an ability such as Pure Eyes, what truly made them so powerful was their Nanaya Assassination Arts that drew upon the limits of the human body. Rather than focusing on their magic or cursed techniques, the Nanaya focused purely on the extermination of the supernatural. To the point they uniquely developed a murderous impulse against non-humans, which would be used together with their techniques to great effect."

"Why are you telling me this, dad?"

"To guarantee all members of the Nanaya clan could possess these traits, the clan maintained the purity of their bloodline by having an incestuous relationship amongst themselves. However........one man was firmly against this process. That man fell in love with a woman outside the clan and even made a child with her. After finding out, the Nanaya clan tortured the man and banished him along with his new family from the Nanaya clan. On that day, the isolated Nanaya's:the Koritsu Clan, was born."

As Ayumu said this, he stopped his stroll as he merely looked at what was ahead. When Shiki caught up to his father, he couldn't believe what he saw. It was the remains of what seemed to be a large estate. The ground looked so burned that no life would ever return to it. Suddenly Shiki's head felt a sharp pain upon looking at this place. Seeing this, Ayumu hugged his son tightly.

"I know it hurts, but to survive the present, we must confront the past. Shiki, it is time to remember. Your origins, your roots, will begin to resurface in your mind. I'm sorry I kept this from you for so long. Now, it is time for Koritsu Shiki to embrace his true nature and to learn just what kind of monster Shiranui is."
