Animeverse Slayer!

No one had any doubt. Muzan will come for her.

Amane continued, "We also have reports of strange marks appearing on Tokito-sama and Kanroji-sama during their battle with Upper Moon Five and Upper Moon Four."

The other Hashiras were startled, "Marks?"

Amane nodded, "During the Sengoku era, there were some swordsman of the first Breath who were one step away from killing Muzan."

"They all had this mark resembling Demon Crests"

Everyone was surprised.

Sanemi asked, "I haven't heard of it. So why are we hiding this?"

Amane shook her head, "At that time a lot of people were brooding about the crests never appearing again. And, that's why."

"A lot of information about the marks became hazy over time, maybe because they were never laid out in stone."

"And the Corps were on the verge of annihilation several times so the inheritance must have died out at some point."

"But there is one piece of news that is consistent, once one person has that mark on them, it starts to spread to others, like as if they are resonating."

"And the first person to have this mark was Kamado Tanjiro."

Leo understood and said, "Amane-sama, the mark does bring tremendous benefit but it has a dangerous drawback."

Gyomei asked, "What is it?"

Leo sighed, "Life. It reduces your life in exchange for power. The mark draws power directly from your spirit. Even considering the best case scenario a person with that mark can only live until thirty, and that's only if they use that power sparingly."

He looked at everyone and spoke seriously, "We don't need that kind of power. When everything is over and done, I don't want to visit you at your graves."

The room went silent.

Gyomei asked, "What do you suggest then?"

Leo explained, "Nezuko has conquered the sun, Muzan will try everything he can to get to her. This is his only chance and so is ours."

"He will come to us. And we will kill him when he does."

Amane cut in, "So it's decided that every Hashira will arrange a training session. Our priority now is to increase true Breath Users. Apart from Tokito-sama and Kanroji-sama, the others have already awakened and acc.u.mulated enough experience."

Gyomei clasped his palms together, "Agreed. Please inform Oyakata-sama that it will be done."

Amane bowed her head and left with her daughters.

Leo sighed, "My workload increased."

Sabito grinned, "Don't worry Tokito is a genius and Kanroji ain't bad as well, I am sure they can reach 'all seeing' realm quickly."

Leo saw his amus.e.m.e.nt, there were people around otherwise a polite middle finger would have been his response.

"Everyone please stay back for some time. We need to discuss the training session in detail."

Gyomei requested for everyone to stay back.

"Guess, we are gonna be busy for a while."

Leo muttered.

...

Each Hashira had a specific training purpose.

The sound Hashira will go through stamina training.

The love Hashira will be in charge of flexibility.

The snake Hashira will be in charge of responsiveness.

The flame Hashira took care of explosive power.

The mist Hashira is on speed aspect.

The wind Hashira pounds infinite smashing.

The rock Hashira will train in muscle reinforcement.

Sabito was the official water Hashira, so he took care of techniques.

The flower Hashira, Kanae mainly focused on treatment so she wasn't tasked with any training.

Giyu and Makomo could freely help any of the other Hashiras.

Leo had a more important task, to train two Hashiras.

The Hashira training focused on new slayers. And it lasted for an entire day.

Kanroji and Tokito were tired from a day of practice but they were dragged out by Leo and forced to fight him.

"I know you are tired and frankly I don't care. You have to grasp that realm as soon as possible. And the best time is when you are on the edge. So let's get started."

Leo fully released his murderous intent. Kanroji and Tokito trembled and took a step back.

"Your task is simple, lay a hit on me. That is, if you are standing."

He took a step forward and appeared beside Tokito. Shocked at Leo's speed Tokito instinctively raised his sword to block. Their swords collided, Tokito was thrown away by the tremendous power behind that attack.

Kanroji woke up from her fear and attacked. Her sword was special, it was made by the swordsmith village chief. It was long, like a whip but strong and deadly like any other sword.

Leo was quite amazed. It was not that easy to master such a weapon, rather than injuring your opponent such a weapon harmed it's own wielder most of the time.

Kanroji had mastered this weapon. She had astonishing flexibility and the power behind her attacks were immense.

However this was Leo. He had long broken through the limits of a Hashira. He easily dodged her attacks.

By now Tokito also joined the battle.

One minute... Five minute... Ten minute... Thirty... an hour... two...

Time went by.

Leo was standing straight with his sword on his shoulders. Kanroji and Tokito kneeled some distance away from him, they were breathing heavily and sweating.

It took them tremendous energy to just stay awake.

Leo curled his lips, "Come on, let's keep it up for another hour."

Kanroji and Tokito nearly passed out when they heard him.

"You both have mastered your forms perfectly but you still haven't mastered your breathing techniques."

"What do you think breathing is? It's a form closest to nature. Every breath we take, we are becoming a part of her, to live, to grow strong."

"So don't breathe for the sake of living, to battle. Breathe to become part of a much stronger existence. Only then can you step into that realm."

"Come on, get up!"

Kanroji and Tokito grinded their teeth and got up.

While Leo was putting them through hell mode once again, a pair of eyes were staring holes at him from the woods behind the training grounds.

Leo had already sensed who this was.

Holy crap! Iguro! Why the f.u.c.k is he so pissed off?

Leo was kind of scared when he saw that murderous look on his face.

It took him no more than a few seconds to figure out what was happening. A wry smile outlined his face as he stared at Kanroji.

Why the f*ck is this happening to me?
