"Thanks Captain."

"What the hell are you talking about? If not for you, me, my men and my ship would be at the bottom of the ocean by now."

Leo scratched his head in embarrassment, "I only did it to guarantee my ride."

A man wearing a captain's uniform shook his head, "It doesn't matter, the fact is you saved us and I am thankful for that."

Leo couldn't say anything more and simply shook his hand, "This is goodbye then."

"Haha, maybe. Who knows, I travel all the time, it won't be surprising if I saw you again."

Leo couldn't hold back his laughter, "Haha, indeed."

Parting with the captain he took out a map and checked where he was.

Quite a long way to go.

Rolling it up he was just about to leave when a conversation caught his attention.

"Did you hear about the murder?"

"Yeah. It was horrible, a whole family was killed brutally. Their bodies weren't even complete."

"I heard that special department took care of the murderer."

Leo was surprised the more he listened. That murder looks like a demons work, and what's this special department? Is it the Demon Corps?

The Corps weren't an official organisation, only small villages knew their existence, the developed areas however knew nothing of them.

He strolled around for some time and found out what was happening.

The Corps had become an official organisation!

Well... though lives were lost in his crazy retaliation, Muzan did us a favour. Oyakata-sama must have realised this was an opportunity. Well, this is good, atleast none of us have to sneak around anymore.

A smile crept onto his face. Gathering some supplies he hit the road back home.

...

"Oi, Tanjiro! Look at this monster!"

"Lower your voice Inosuke, people are looking at us."

"This is amazing."

Three young men about the age of sixteen stood beside a train. One was b.a.r.e c.h.e.s.ted and wore a boar skin mask. The other had a scar on his forehead and wore a checked haori. The last one had yellow hair and wore a yellow haori.

All of them had a sword strapped to their waist. These three were of course Tanjiro, Zenitsu and Inosuke.

"Hey, you three! Are those swords?"

Some policemen ran towards them when they heard Inosuke's loud voice.

Tanjiro apologized, "Sorry, sorry! My friend is a little excited, this is his first time on a train. Oh, we are from the special department."

He took out a small book. It only had two pages, one had his picture, name and rank. The other page had an emblem slayers usually have on their swords.

"Oh, you are from the special department. So young!"

Zenitsu rubbed his nose and had a proud look on his face. Inosuke simply ignored them and pounded on the train's steel body.

Tanjiro yelled, "Hey! Stop that, Inosuke!"

The police officer smiled, "Your friend sure is excited. Anyway, good luck."

Tanjiro thanked them and grabbed the other two to board the train.

Zenitsu asked, "Didn't Oyakata-sama order Hashiras to always pair up? What happened with this one?"

Tanjiro was trying to find the Hashira when he heard Zenitsu and replied, "Something came up and only Rengoku-san was free. So we were put as his reinforcements."

Just as he explained he saw a man with long hair with red locks up front. He was stuffing himself with food and yelling to himself that it was delicious.

"Rengoku-san!"

Tanjiro yelled out. Rengoku looked back, "Ah, Tanjiro! So you are my backup, I can rest easy now!"

He pointed to the seat next to him, "Sit down, have some food, it's good."

"Inosuke!"

"That idiot boar!"

Zenitsu and Tanjiro jumped out and grabbed him. Tanjiro smacked Inosuke so hard he was seeing stars.

Rengoku had a hearty laughter when he saw this.

When they settled down Rengoku explained their mission, "Reports show people disappearing in this train. There is a chance of this demon being a moon so be cautious and alert at all times."

The train travelled through the silent night. At first all four of them sat straight and had their eyes pried open. But as the night passed, their eyelids got heavy.

Tanjiro and co. fell asleep. Rengoku tried to peel his eyes open but in the end he also fell asleep.

"It's done."

A demon with the character of one and lower carved into his eyes stood atop the train. She had half of her body merged into the train.

These two were Upper Moon Three and Lower Moon One.

Upper Moon Three stepped forward, he stomped on the black roof beneath his feet. The roof collapsed and he jumped in. His eyes scanned past everyone and focused on Rengoku.

I would like to have a good fight with you but Muzan-sama ordered me to kill you as fast as possible, so, sorry.

A glittering hexagram with carved runes appeared beneath his feet. He pulled back his hand and punched out. Along with his strike he took a step forward and vanished.

In a split second he was upon Rengoku, his fist whistled as it drew closer to its target.

"Farewell, Flame Hashira!!"

Lower Moon One already had a smile on her face but a second later her smile stiffened. An unbelievable change was happening before her.

A second away from smashing Rengoku's head Upper Moon felt a prickling sensation on his neck. Startled he pulled back his arm and retreated.

Inosuke's sword swept past where his neck was. Tanjiro also opened his eyes, his swung his sword, Upper Moon smacked it away and retreated.
