Demon Lord's Reincarnation

The Shadow Clan a true demon clan that survived the ending of an age. They were a legendary Clan that lived and died in the shadows. Normal people don't even know of their existence but those in the know understand that their power and influence was able to rival a nation. Now the current Shadow Clan is nothing like its predecessor. It had weakened a considerable amount, but it was still considered a rather fearsome Clan. Most of the best assassins could trace their lineage back to this Clan. 

The current head of the Shadow Clan wasn't a direct descendant of the Shadow Clan Horned demons, instead, he was a descendant of a demon that was lucky enough to have learned their techniques, through a series of incidents. The name of the current head was Henry and though the blood of demons that flowed through his veins was so minuscule that you could say that he was fully human now, the current head still respected his ancestors.

The day when he heard Luke's report regarding Ren he felt excitement and joy that he had never felt before. All of the members of the Clan even started crying, it was at that moment Henry's twin sister Nila whispered in Henry's ear.

"What are we going to do brother?" 

"Hmmm, if what Luke says is true then we of course need to greet this descendant. Still... A few words and actions can't really tell us much, so even now I'm not entirely sure if he's actually the real deal. Though it is true that those words can only be said by the head of the clan, and you'll die if other clan members say it, but if a normal non-clan member said it nothing will happen. As for the skill he used, I learned that there are many skills that could replicate the effect of [Shadow Holding]. So overall we need to reassess this so called descendant."

Even though he said all that, the truth was Henry had already believed that Ren was the actual direct descendant. Still, he didn't want to let this chance go. He wanted to see the full capabilities of an actual descendant of the Shadow Clan. He wanted to see if his techniques which he and his clan members honed for years were truly just imitations. He wanted to prove that what they learned and stacked up over the years could match up to the supposed original. 

"We'll head to New Grenton and see for ourselves if this person truly is who he says he is." 

...

Henry who was hiding in the shadows using [Shadow Treading] was surprised by what he was seeing. The person called Ren who was supposedly the true descendant of Demon Lord Kretos didn't have the smell of a demon, it felt like he was a pure human, but still, there was something about him. 

As the Shadow Clan continued to observe Ren, the person in question suddenly approached one of them and picked him from within the shadows, and was incapacitated by Ren. 

As Henry was trying to figure out how Ren detected them, one of Ren's companions the beautiful maiden with blood-red eyes started dispatching them one by one. She wasn't killing them but the way she easily spotted them was a big problem. Henry then gave a signal to the others to start attacking. 

The Shadow Clan members started throwing daggers at Ren's group who easily evaded and or caught the daggers. The Shadow Clan members were surprised by how easily their surprise attack was evaded, but then one dagger was actually able to hit one of Ren's companions. As they began to think that they actually got one, that person that was hit casually pulled the poisoned dagger out and started expelling the poison within his body. That was the most shocking sight they saw today, as the Shadow Clan members became a bit dumbfounded, it was then Ren suddenly did something they weren't expecting.

Ren's shadow started to expand covering a large area. When Henry and Nila saw this they quickly got off the Shadows way. Unfortunately, most of the Shadow Clan members that were with them were unable to do the same thing and got caught within Ren's shadow. Those that were within the area of Ren's shadow could no longer move and were forced out of their [Shadow Treading] revealing their locations. 

Ren then summoned numerous chains from his shadow binding the Shadow Clan members. 

"Oh, so there are actually two of you that know what they're doing. Still, how sad it is to see that the Shadow Clan has fallen so low. If it was the old Shadow Clan, the moment I spotted one of you, the others would've immediately retreated and try to gather more information on the enemy. Yet you guys did the exact opposite and actually started attacking. Not only that, but each of your attacks were too weak. As a member of the Shadow Clan, you must know that each strike is meant to kill, if you're not sure that one strike could finish the opponent you would never try to do it. Also even if you do attack the moment it fails to kill the next step would have been to retreat which all of you failed to do." 

Ren sounded so exasperated and disappointed that it made Henry and Nila unconsciously clenched their fist. 

"I wonder which old Shadow Clan member survived to teach you sh*tty descendants. Sloppy and shabby techniques, you guys aren't worthy to be called the Shadow Clan. The way you move makes me think that your ancestor must've been a reject of the clan." The moment she heard this Nila wanted to attack, but then Henry stopped her. Ren continued to hurl insults but Henry and Nila continued to hide. 

"Oh, that's a bit impressive that you're still not attacking despite my provocations. I guess you guys aren't all that worthless after all... I didn't want to do this, since using the ways of the Shadow Clan wasn't really my style, but as a prize for giving me quite a surprise, allow me to show you, how a true Shadow Clan member fights."

It was that moment Ren's body started to fade until he disappeared from sight. His presence, his overwhelming aura, everything even his mana fluctuation disappeared.
