Sorry for the massive delay, it took me a while to figure out the structure of the story and work around. This takes place after the Entertainment Arc, so they are stronger than the Mugen train arc. This is going to be epic.

With the Young Demon Slayers.

''You think that Hashira is still alive?' Asked Inosuke.

''Uzui-sam lost a lot of blood but he is still ok. I write letter for him and his wives once a while.'' Said Tanjiro.

''Yeah, why should we keep contact with that guy?" Asked Zenitsu.

''Come on Zenitsu. I know you don't like his style, but he saved our lives.' Said Zenitsu.

The trio was busy working out and getting stronger. The Hashira were soon going to start a powerful training session and they need to show everything they got. However, they need something else.

''We need new swords.'' Said Tanjiro.

''Aren't your sword good?" Asked Inosuke.

''My sword are not good for Demons at the moment. I need get better one.'' Said Tanjiro.

''Isnt the guy that makes your sword a dick?" Asked Zenitsu

Tanjiro didn't know what was going to happen. He got death messages from the craftsman that make his sword and he was pissed that he broke another sword.

''i am so dead.' Thought Tanjiro

Soon after a few hours of training the insect Hashira Shinobu appeared.

''Boys, I have an announcement.'' Said Shinobu.

''Yes Shinobu-sama.' Said Tanjirou.

''You receive a message from the master.'' Said her.

''A message from the master?'' Asked Tanjiro nervous.

The group read the message out loud to know what could Ubuyashiki be talking about.

´´My dear children, we received terrible news that a monster has been attacking some villages near us. From what I heard its looks nothing like a demon so I would like you three to look and see if it's a threat. ´´

''So he wants us to see what is causing all those deaths?'' Asked Tanjiro.

''Only to explore, if something happen one of us will be there to assist.'' Said Shinobu.

''Only us against a creepy thing that is killing innocents?'' Asked Zenitsu with fear.

''YEAH!' Scream Inosuke excited.

The group soon got dressed up and get ready to discover what was causing all those deaths. The swords were ready and it was time to slay.

Later

The group was all there, including Nezuko because it was night, and she could be taken care of with more calm. Now they were on the region where the deaths were happening.

''Can we go back?" Asked Zenitsu.

''We can't I sense that we are close.'' Said Tanjiro.

''You and your damm nose.'' Said Zenitsu.

''Dont tell me where is that monster! I will kill him in a swing!' Said Inosuke.

''don't make more noise stupid boar!" Scream Zenitsu.

The group of demon slayers were lively as always. Even in a quest they were full of life and energy.

On the forest.

The group was now on the forest, and they could tell that something savagely happen. Body pieces were in the trees and holes everywhere, what was weird it was that this didn't sound like a demon doing.

''Its weird. Demons enjoy every bit of flesh. This one is just wasting.'' Said Tanjiro.

''Do you think he is saving snacks?" Asked Zenitsu.

''What a glutton bastard!'' Said Inosuke.

Then Tanjiro felt something coming and the other two soon got their swords ready.

''What is it!'' Asked Zenitsu.

''Is a demon?" Asked Inosuke.

Tanjro smell what was coming and it was as bad as demon but no likely.

''No.'' Said him

''Then what is it?" Asked Zenitsu.

''I don't know.'' Said Tanjro.

The culprit soon arrived. A giant man lizard with a snake mouth, he looked scary as hell since he still had blood in his mouth.

''Is that a demon?" Asked Tanjirou confused.

''Well is that more heroes to chew?" Asked the snake man.

The demon slayers have no idea on what was that thing. It looked like a demon but it didn't felt like one.

''What is this?" Thought Tanjiro.

The creature was a chimera ant that awaken his nen that was transportation. As far he can make a hole in the ground the far he can go. He ended up digging too much that he ended up in another world.

''Ever since I made that whole thing have been easier. I will be the king of this world.'' Thought the chimera ant.

The demon slayers prepared their swords and were ready to attack

''Let's kill the snake bastard!' Scream Inosuke.

The trio felt that they could win but something tell them that this won't be as easy as they thought.
