64 Chapter 64 - Ravenous Breath

Exactly 11 months had passed since he had spent living with the Kamado family and their things that he had discovered along the way. His love for Nezuko and Kie that he didn't want to happen but it just did. He dislikes the thought of stealing a man's from another unless that person is toxic.

It made him livid at himself that he grew to understand how much they left an impression even more when Nezuko asked him about leaving them. His feelings towards them had run deeper than he expected.

Regardless of what may have happened, Ryuu would keep them in his heart and love them. He knew that it was the twisted gods that made him this but couldn't hate them as he came to know more about himself.

Putting aside his inner conflict, he had accomplished what he needed and completed his breathing technique forming exactly 13th form.

Ryuu's stamina had grown to have an endless amount and the breathing technique had also provided control over his magical energy despite not having [ Precise Mana Control ].

[ First Form - Pestilence Strike ]

[ Second Form - Death Step ]

[ Third form - War Slash ]

[ Fourth Form - Black Plague ]

[ Fifth Form - Raging God Wheel. ]

[ Sixth form - Raging Blizzard ]

[ Seventh Form - Blessing Of Spring ]

[ Eight Form - Summer Drought ]

[ Ninth Form - Autumn Leaves ]

[ Tenth Form - Leviathan fang ]

[ Eleventh Form - Behemoth's stomp ]

[ Twelfth Form - Dragon Benevolent ]

[ Thirteenth Form - Ravenous God ]

He mastered the technique in a short time thanks to the Dimensional room. Ryuu found that the more he grows stronger the slower it gets.

It made him conclude it was either the world limiting him or it was just that he needed something to break the 'Wall' which is a term used by Vandalieu's world when they are unable to level up.

Regardless of what the sadistic gods are planning for him, he would face it head on since there is no more turning back. I have acquired a few more mundane skills from [ Toy Maker ] and [ Businessman ].

They were both an Innate Skill and didn't mind the extra skills. It gave him extra things and made some sort of Isekai protagonist who made modern things. He created a few toys for the children, finding their smiles delightful.

Putting that aside, Ryuu had surprisingly acquired a Demon Slayer Mark on my chest that spread through my neck like some sort of disease. The image was bizarre and creepy in Ryuu's mind but he could deny it was befitting to his Breathing form.

It was worth noting because the tempering pills that he and the rest of the Hashira had been taking prevented them from dying at an early stage.

The vision of the Transparent world was useless when he had [ Byakugan ] that gave the same effect, However, when in use it provided an abnormal perception of time and let him see the tiniest detail.

"Swing slower and give more power! Try to hold your breath as much as you can!!"

Ryuu was teaching Tanjiro on how to wield the blade using a plain old Katana. He was surprisingly faster learning the Sun Breathing Technique than anything else.

His body wasn't suited for Ryuu's technique as it is a revision of all Breathing Technique and improved to its utmost limits.

He would need a body similar to him if he's going to learn it. Regardless, Tanjiro learned every technique in [ Sun breathing ] relatively easy compared to [ Water Breathing ].

It made him ponder if Tanjiro was the reincarnation of Yoriichi since it was too fast and no one had mastered the Sun Breathing technique beside the one who made it.

Ryuu had run out of the Body Tempering Pills which is why he hadn't been helped to increase Tanjiro's body and couldn't buy it since each bottle was extremely expensive.

Though, he made sure to fix the curse of the Demon Slayer Mark to avoid Tanjiro from dying. This begs the question if Tanjiro lived more than 25 in the canon.

'How depressing…'

Even after they went through it was a heartbreaking tragedy knowing how hard they fought in the end it was a pitiful end. Ryuu shook his head at the thought and focused on Tanjiro who had the same skill set as Hashira.

[ Side Mission ]

[ Task: Stop/Kill/Cripple the surrounding Mercenary that had gone rogue.

[ Reward: Shundō, Kokū Shundō, 2,000 points ]

Ryuu raised an eyebrow looking at the screen wondering why it was Shundō instead of Shunpo. It seems a different technique than Flash step from Bleach. He knew that this Technique would be useful in a fight.

"Alright, Continue training, I'll just go for a stroll." Ryuu said to Tanjiro.

"A...alright...haaaa..sensei!"

He nodded using [ Death Step ] to move near instantaneously moving in speed near the speed of sound blinking in and out. Ryuu's breathing could continuously perform the technique without tiring but needed at perfect pace.

Running through the forest at a high speed eventually leads him to the forest where he uses [ Byakugan ] that spans nearly a 100km radius. His expression changed from carefree to serious emotionless gaze.

[ Fourth Form - Black Plague. ]

Ryuu took a deep breath moving in blinding speed moving in a manner that appeared to be miasmic black mist. The mercenaries who had turned into bandits unable to see what happened when their men showered in the blood of their allies.

He hardly feels anything when the [ Gluttony ] views them as nothing more than prey to be slaughtered. Ryuu decided to avoid drinking filthy human's and only taste his lover's blood. It tasted awful after consuming numerous demons' blood that improved his ability by a bit.

Ryuu was relieved when he recalled that most of the demon's blood came from Muzan and was afraid of being a puppet but fortunately it didn't work and didn't feel any influences whatsoever.

"What's going on!?"

"Gaaaah!! He-Help!!!"

"P-Please don't kill me!!"

Their eyes were filled with despair, unable to face the reality that they were being slaughtered one by one. Unfortunately, Ryuu has no mercy for people who trampled in the lives of hard working and honest people.

There were some who tried to retaliate using an old rifle firing towards Ryuu who didn't bat an eye when he did a downward slash splitting the bead into two killing the enemy behind him and using the momentum to draw the blade behind him and hook them before.

[ Eleventh Form - Behemoth's stomp ]

He proceeded to slam their body into the ground crashing the people around them that caused fissures on the ground. It only lasted for ten minutes until all the mercenaries were squirming in pain.

Ryuu sheared his blade before using his magic to gather the corpse and crushed them together to be home smaller afterwards made multiple clones to bury the bodies.

Finish his job by also compressing the blood before storing it in this inventory for later.

"Hmmm? What!?"

He yelled out looking at the man and found that some of the mercenaries were surrounding the Kamado house.

Ryuu was furious that someone played him like a fool and flashes his way through the forest finding the mercenaries hiding. He didn't waste any time to slaughter them all but made it quick to not let the children see the carnage.

He uses his magic to make needle spikes around him like Vergil to pierces the bandits that wouldn't cause much blood. It took mere seconds to massacre them all and remove the blood around his body before going straight to the lake where he found Kie pinned down.

"R-Ryuu save me!!"

Without a moment of hesitation, he kicked the man with such immense force that it flew several feet, breaking every bone in its body, killing him instantly. Ryuu looked down to see Kie having dripping down her cheek causing him to warmly smile and saw her naked body.

'She's quite sexy….what am I saying!?'

Ryuu shook his head and wondered where the thought came from. He does find Kie attractive but she is always wearing motheringly attire that he hasn't seen her figure. It was all because of his weird attraction to older and mature women.

"Kie, you can go back with the children. I'll handle the rest."

"N-No, I can't leave you here! What if you get hurt!?"

"Hahaha if I come back unarmed then I want a kiss as a reward."

He jokingly said trying to lighten up the mood that made Kie blush from the thought of kissing him.

"I-If you win then I'll give you more than a kiss."
