Animeverse Slayer!

At first Leo was preparing to head straight for the Corps but then he decided to take his time and travel a bit before going back.

He was supposed to get on the train at the next station when he felt the fluctuations of a battle. Considering the distance he knew it was a Hashira and his opponent was an Upper Moon.

However what he didn't expect was the sight of his friends laying in a pool of blood.

Rage and bloodl.u.s.t oozed out of him, Upper Moon One felt as if he was being stared by a primordial beast. His hands trembled.

Why is he here!? Didn't Muzan-sama send him far away!?

A lot of questions flashed through his mind. However he knew now wasn't the time to ponder these issues.

He took a step back and escaped. He didn't even spare a look at Upper Moon Three.

Leo scoffed. He pushed off of his feet and disappeared.

Upper Moon One felt an ominous foreboding, his six eyes suddenly saw a figure appear out of nowhere like a ghost. A blazing red sword was poised high and crashing down on him like a strike from heavens.

Aaahhh!!!

Roaring at the top of his lungs Upper Moon One swung his sword. Along with it his body started to change, dozens of sword with eyes emerged out of his flesh and stabbed towards Leo's incoming attack.

But it was all useless.

Like a piece of paper it was broken through. Leo's sword cut through the flesh swords and sunk into his body. A scorching sensation spread into his mind, he looked down to find his body being burned.

"Your had your fun with my friends."

Leo's cold voice reached him. He took a step back and pulled away from his sword.

"Kill the... puff!"

He yelled at Upper Moon Three to kill Inosuke and Zenitsu inorder to distract Leo. However before he could finish his words Leo's fist sunk deep into his gut.

Upper Moon One's spine broke in half, he was punched away like an artillery shell. Upper Moon Three finally snapped out of his horror only to see Upper Moon One fly in his direction.

Subconsciously he raised his hands to catch him but a tremendous force crashed into him. Both of them collided and rolled through the ground.

When the dust settled the two of them were covered in blood. Leo took a step forward, he seemed to have stepped through space and appeared right infront of them.

"Be on your way."

His domain spread out, two slashes went forward. Upper Moon One and Three fleet a shiver down their spine. A breath away from death a black hole appeared beneath them.

Leo frowned. This was the same ability that threw him to the other side of the world.

Leo vaguely heard a sharp scream before Upper Moon One and Three disappeared.

He sheathed his sword and shook his head in regret.

Immediately he returned to Tanjiro and the others. Placing them all together he opened a small bag on his back. Several bottles were neatly lines up inside.

He pulled out one particular bottle, making a rough calculation he took out four injectors and squeezed out about half of the liquid from the bottle.

He injected all four of them with it. After several seconds their bleeding stopped, it was slow but their wounds were healing.

Leo heaved a sigh of relief and waited. Not long after a group of police officers and kakushu came running.

Leo instructed the kakushu, "I have already done preliminary treatment. Their bodies are spent so transfer them to the headquarters."

Though it been more than a year since Leo disappeared some of them recognised him. They were pleasantly surprised and excited at the same time.

Leo rode with them and reached the headquarters by the time the sun was up.

His spirit sense already picked up that familiar presence. He smiled a bit and walked in. Opening the door he saw Shinobu, reading a book.

Shinobu was trying to relieve some stress by reading when she heard the door open. At first she thought it was her sister but the footsteps sounded different.

She nonchalantly looked up and froze. A second later she jumped on her feet and rushed forward. Her hands wrapped around him.

Leo was stunned for a second but a smile appeared on his face. He hugged her back, her body felt soft and comforting.

"I am back."

...

They stood there like that for a while before separating. Shinobu's face was as red as a tomato. Only now did she realise what she did.

Leo pinched her beautiful cheeks, "You have grown... in all aspects."

Her cheeks got even more rosier. She simply turned her head around in embarrassment.

"You... you...

Leo licked his lips, "So sweet."

Shinobu was embarrassed beyond words. She hung her head down and dared not to look up.

Suddenly Leo sensed a familiar presence but he frowned. He turned his head and found a young girl wearing pink clothes run in.

"Ne...zuko?"

Leo was stunned. This was obviously Nezuko but her spirit was so jumbled that he couldn't make heads or tails about it.

Shinobu snapped out, she saw Nezuko and didn't know how to explain it to Leo.

"Shinobu, what happened? What's wrong with Nezuko?"

Leo's words were rushed. He walked forward and stood infront of Nezuko who looked at him curiously. However a second later she hugged him.

Shinobu said slowly, "A month after you vanished Tanjiro's family was attacked by Muzan. Tanjiro was down at the town when it happened, only Nezuko survived and... this is how she has been after."
