Demon Yoriichi Tsugikuni

Chapter 10: Demon Slayer Corp

Hours have passed. Kokushibo and Yoriichi had a tough training.

"You've improved a lot aniue! It seems we have similar blood demon art too." Yoriichi commented.

"We are breath users.. so no suprise since we use our blood demon art to enhance it." Kokushibo spoke.

"It definetely night time. Let's go outside brother, I'm eager to continue foiling more of Ubuyashiki's plans." Yoriichi was truly devious. Kokushibo smiled.

Kokushibo was very curious. How can Yoriichi can easily figure out Ubuyashiki's hideouts? Yoriichi explained whenever he hunts on his own he comes accross the slayers. He negotiate them and persuaded them for answers. That how he knew.

"How come you didn't inform master yet?" Kokushibo questioned. "I still didn't go there yet. So I needed to confirm this first."  Yoriichi replied.

The two continued to walk until they've seen a huge building. They can sense humans. They jumped to the roof and roamed around. "Swords.. that is a training area.. That must be it. This is the demon slayer Corp." Yoriichi feeling ectastic. "Most slayers I negotiate always choose death. Guess the ones you were taking care of were not loyal." Kokushibo spoke.

"Yoriichi. We need to make up a plan before we make our move." Kokushibo explained to Yoriichi. This gave Yoriichi an idea. "Then let inform master what we know and make up a plan. I'd love to see them enjoying their time with each other before the real genocide begins." Yoriichi smirked.

Yoriichi heard sobbing and it was a slayer sitting on a tree all by herself. He deformed himself to look like human and approached her. "Why are you all alone at night? is there something wrong?" Yoriichi approached her. The female slayer noticed and quickly wiped her tears away. "I'm sorry.. I don't mean to trouble you.. it has nothing to do with you actually.." The female replied. "Well you do seem like you really want to talk." Yoriichi responded.

"You're right.. it just. I had a fight with my friends because I couldn't slay a demon when I had the chance.. I even hurt her feelings.. I don't think I make a really strong slayer if I couldn't get a weakened demon.." The female broke in tears.

Suddenly.. Yoriichi found this.. familiar.. 

Killing the demon when you had the chance... friends blaming you... unable to kill a weakened demon...  

Yoriichi suddenly got a headache. "Mister? are you okay? Let me take you to Lady Shinobu! she'll help you." The female slayer tried to guide Yoriichi until Kokushibo stepped in, disguised as human. "Sorry for the trouble. my brother is really tired." Kokushibo carried Yoriichi. "Woah. brothers? you two must be twins!" the female replied.

"Damn it Yoriichi.. how can we get away now that there is someone who seen our prescence." thought Kokushibo.  "What are your names? I never seen you two before.. you're not wearing the uniform either. Are you guys new?" The female spoke asking several questions. "It not important. your head and body will have a sorrowful departing after all." Kokushibo replied.

The female slayer got confused. "What do you mean-" she could not finish her sentence as Kokushibo beheaded her. Yoriichi finally woke up. "My head hurts.." Kokushibo held Yoriichi and asked him what was going on. "I don't know.. I.. suddenly.. started to remember something.. everything she said is so familiar I... my head hurts when I try to remember." Yoriichi held his head. 

Kokushibo knew. Muzan informed him that Yoriichi is not meant to remember anything. But he somehow remembered his older twin brother. But he was not informed why did Muzan erase his memories. "We'll discuss this later. I sense humans approaching, we must go." Kokushibo teleported away while carrying Yoriichi. 

The two slayers who heard some noises went to check it out and was shocked to see a beheaded slayer. The two slayers were the friends who blamed her. Overfilled with guilt they began to cry unable to apologize in time. The male slayer quickly went to inform the others while the female continued to mourn for her friend.

Meanwhile

"Nakime. You may teleport us." Kokushibo called out for Nakime.

The twins got back to the infinity castle. "Where is master Muzan? we got something important to tell him." Kokushibo asked Nakime. "Lord Muzan is busy doing some works. I can teleport you to him right away but I'll ask for permission first." Nakime replied. The twins waited a few min until a biwa sound was heard. 

Kokushibo and Yoriichi were teleported to a huge room with tons of chemicals and experiment tools. They knelt down when they saw Muzan standing in front of them. "It should be important. Tell me what you discovered." Muzan asked. 

"We found the demon slayer Corp master. We took a quick look around and confirmed we found their hideout." Kokushibo replied. Muzan was fascinated. "Wonderful. Your next move will be to destroy them. If we wipe out the demon slayers there will be no resistance." 

Yoriichi was silent. He is slowly remembering something he was not supposed to. "Yes. We understand master." Kokushibo responded. Muzan then dismisses the twins and decided to change his form to something smaller. A child form. "I will head back to that mansion. You two are in charge in the infinity castle while I'm gone." Muzan then left off to quickly get to the mansion before daybreak.

"Aniue.. aren't we demon slayers who are meant to kill.. demons?" Yoriichi questioned. Kokushibo's eyes widened then suddenly he heard a voice. Muzan's blood cells inside Kokushibo is able to see it all. "Keep toying with him. He must NOT remember. If you do. I'll give you more blood." Muzan talking to Kokushibo in his head. 

"No Yoriichi. We are demons. Humans are our real enemy. We who once were slayers were never treated like one of their own. Why side with those who went against you?" Kokushibo persuaded Yoriichi. 

"They went against us..? after everything we helped them..? ... Unforgivable.." Yoriichi was angered.

Kokushibo feels awful all of a sudden but it was Muzan's orders. No matter what, he must obey.
