Chereads / Demon slayer op system / Chapter 5 - First mission

Chapter 5 - First mission

"Gak! Gak! Wake up, Murata Takenuchi. Your first mission has come!"

I wake up to the sound of the crow.

*Yawn* "Which direction is it?"

"You should go directly to the north, you should be there in 2 days."

I guess it's time to go then.

A day later-

As I enter through the entrance of the village, I see someone arguing with a women

"Why didn't you notify me when I was sleeping! I could've saved them if you did!" the young man said with madness

"I was too scared! I couldn't even move when I saw him!" the woman shouted at the man

"B-But you could still wake me up so that I could at least try to save them!" the man said holding back his tears.

"Um, did something happen to you two?" both of them looked at me baffled

"It doesn't matter to you, why bother." the man looked at me with annoyance.

"It does matter since I lost my parents to an unknown being who killed them." Lying was the best option to get some information out of these two

"I would highly appreciate some information about that being."

The woman spoke first as she was the one to see the demon

"He wasn't human, it's just better to leave this case alone if you don't wanna die."

"Please! Just a few pieces of information will be enough. I beg you!"

The woman sighed as she heard that

"Alright, I'll tell all I know. First, he used some techniques to make us unable to move and killed my parents in one move, I don't know why he didn't kill me. It seems that he's just targeting people who have kids if your parents were also killed by that man." the woman spoke

"Thanks a lot, I will have revenge on your parents." I said as I ran to the city.

It was already an hour before nighttime and I decided to eat some ramen before going into a fight.

Nighttime-

I start to search homes to find the demon, and after a while, I see the demon preparing to attack silently so that he won't get caught, but as he was preparing, I approached him from behind

"Sun breathing: Clear blue sky!"

As I was about to slice his head off, I hear something.

"You fool. Blood demon art: 60X Gravity!"

As I hear that, I completely crush to the ground and all I could was just look at his eyes

'Lower Moon 2'

'He's a lower moon?! I need to get up!'

I try to get up but was interrupted by the lower moon two slashing my right arm off with his claws

'Argghhh!! Although I have pain resistance, this shit hurts a lot!'

"You're done already? And here was I expecting a great fight. The blame is on me though."

I start to heal my right arm with the ability I got from the hand demon. Honestly, even I was surprised that I could regrow my limb that fast.

"What!? How can a human regenerate this fast? By any chance, are you a demon?"

I try to stand up using all the strength I have and enter the see-through world state

'I'm feeling fast compared to a little ago. I think I might win this.'

The demon throws a few punches at me, but I manage to dodge all of them."

"Sun breathing:Fake Rainbow!" the moment the demon throws 1 more punch at me, I appear behind him and try to slash his neck, But he cancels the gravity effect before dodging

'What? Why did he cancel the blood demon art? he should dodge it easier when I'm slowed down. There should be a weakness in his demon art, Or else even Hashiras would have trouble with him, anyways ill take this opportunity to attack.'

I rush him with my sword ready to slash him in two, However, he dodged my attack.

"Blood demon art: 20x Gravity!"

I felt my body heavy again, but it was a lot better compared to the last time he used that technique.

"Human, what is your name?" the demon asked

"It's Murata, Murata Takenuchi."

"And my name is Rokuro, Shall we continue then?"

"Yes, there's no need for distractions."

And as the demon rushes towards me, my mind came up with something.

'Wait, by any chance, the reason why he canceled the BDA earlier was that my swing would be too strong with 60x gravity, I would be 60x stronger with his BDA activated, I should use a technique that is almost impossible to block... Oh! That's right' my mind came up with a technique that I could use in this fight.

"Sun breathing: Dragon sun halo head dance!"

That technique was just slashing my sword repeatedly and gaining momentum.

I didn't give him the time to cancel his BDA and kept swinging my sword until he couldn't dodge.

'Ah! An opening!' I saw an opening and slashed there with incredible speed, and just when I was halfway done, he made my sword change directions to prevent me from slashing his neck. He quickly retreated after I pulled my sword out of his body.

"Human! Are you perhaps a hashira?!"

He tried to distract me from fighting by talking to regenerate himself, but I didn't take it. I rushed at him with incredible speed.

He sees that I ignore his talk and throws a few punches at me.

"Sun breathing: Fake Rainbow! And then...

Sun breathing: Setting Sun Transformation!"

I first left a few afterimages when he attacked me, and then did a backflip to slash his neck.

"Just a little faster..." he was just about to dodge when I felt something hot in my body...

It was a strange feeling but I felt like I had been overflowing with power.

[ Demon Slayer Mark Achieved! ( Peak, Passive )]

I ignored the system's notification and focused directly on the fight. Even though he dodged the attack, it felt like I could slash his neck in a single second.

'This power is great! I might get addicted to this.'

"Sun breathing: Solar Heat Haze!"

This technique's specialty is to make your opponent think that the sword hasn't slashed yet, but thanks to its haze, it would've already slashed their neck.

The demon couldn't see the blade at that one moment, he dodged it but after a few seconds, he felt something separate from his head, he tried to touch the spot where the injury is, but couldn't feel his whole body except his head.

'What? How did he... But I don't wanna die yet, there should be something I can do. Yes! There's definitely some way out of this situation! There should be!' Rokuro denied this situation, he became a demon thinking he could live eternally.

"What a pitiful demon you are, killing people and not thinking about the outcome... You just honestly piss me off." Murata didn't know why but he was pissed at the demon very bad.

'Why do I feel like this? Is it because I use sun breathing and inherited yoriichis will? Either way, I don't think being a good person is a problem so I don't care.'

And with this, the fight ended in Murata's victory.
