"Young boy, it's time to wake up." I heard a voice, it was a familiar voice and kinda relaxing too.
'Huh? Where is this place? I remember fighting with the lower moon 2 and winning but who is this person?' I couldn't even open my eyes, it's not like I didn't want to, it's just I couldn't
"You don't have to force yourself to speak, rest here for a bit." Again, who is this? I can tell it's a female but I don't exactly know who she is. This place must be something similar to a hospital, and if she is a doctor that must mean... Oh! This place is the Butterfly mansion and she must be either Aoi or Shinobu. I have to get up fast
'Damn it! I can't even move a single muscle, I want to meet the female characters so bad! I guess I'll wait here until I regen.
------------------------------------------------------------------------
A few days passed after that, and I was almost completely healed thanks to my regeneration speed and when I woke up, Shinobu was already gone. They said she went on a mission after taking care of me for a while. And when I was lying down in a bed resting, I heard the system's voice.
[Hidden Quest Completed: Kill a Lower Moon
Rewards: 20000 Gold Coin
Level up!
Level up!
Level up!
Level ...
Lev...]
'Wow...' That was all I could say about this. It's probably because I haven't killed any strong opponents yet so my level hasn't gone up a single bit.
'System, show me my status.'
[Name: Murata Takenuchi
Hp: 78000
Bloodline:Saiyan Bloodline (50% unlocked)
Strength: 1.51k
Stamina: 1.45k
Dexterity: 1.45k
Stat points: 3400]
'I leveled up a lot just because I killed a lower moon. I wonder what will happen when I behead an upper moon.' And now to how to spend the 20k coin, I probably should buy a skill that'll be very effective against demons.
Given that most of the upper moons or muzan barely appear, I should probably get a navigation skill that'll make it easier for me to find muzan.
'System, buy a navigation skill that'll show me the location of cannon characters.'
[Understood, Host.]
[Skill: Navigation purchased! 1000 gold.]
And Infinity for defense and 10-Tailed Beast mode for offense.
[It will cost you 15000 combined. Do you confirm the purchase?]
'Yes'
[ Infinity And Ten-tailed beast mode purchased.]
Alright, I'll just wait here I guess.
A few days later-
"Hey, newbie! Lord Ubuyashiki is calling you to his mansion. I'll locate you at his house."
'I guess it's finally time...' I have been resting here for some weeks and was completely healed.
I had to cover my eyes all the travel because I wasn't allowed to know where lord Ubuyashiki lived.
After a few hours, we finally arrived there.
"Newbie, open your eyes, you're in front of Hashiras."
I open my eyes to see all the hashiras in a line, staring at me
"My child, How did you kill a lower moon although you became a demon slayer a week ago." A kind voice spoke to me, he was asking me private questions but I felt no pressure talking to him.
"I don't know, I just encountered him because of the mission you gave me." I said the truth because even I didn't know there would be a lower moon.
"Well, let's cut things short, Murata-San, won't you become a hashira?"
'Well, I kinda expected that. To become a hashira you need to either kill a lower moon or kill 50 demons and that means I'm able to become a hashira now. But I'll refuse since I don't want any responsibility on me.'
"Thanks, but I will refuse that offer since I want to travel freely."
"How dare you refuse Ubuyashiki-sama's offer!" Sanemi stood up but quickly sat down because of Ubuyashiki's hand.
"That's okay, but can you tell us about the breathing technique you used? Your crow told us it had red color and was not flame breathing."
"Of course, it's the origin of all breathing techniques And called Sun Breathing."
They all looked at me with surprise in their eyes.
"How do you know that?" it was Rengoku who spoke first.
"The person who taught me this breathing fought with Muzan, and Muzan himself questioned him when he saw this breathing." I had to lie there because I had no proof that it was the first technique.
"You may be right, my father used to read a book that contained various breathing styles, I'll just ask him to verify this information."
"Then I'll leave that to you, Kyojuro." Ubuyashiki said with kindness in his voice.
"Now to what you spoke about your trainer, who is he and how did he find Muzan?"
"I can't tell you since he's already dead, and even I couldn't get him to tell his fight with Muzan." I'll just think that my trainer is Yoriichi so there would be at least something real.
"Um, if it's alright for me to speak, why didn't he tell about his fight with Muzan, does he not want us to defeat him?" Shinobu spoke next, causing me to think for a while.
"There were people he told, but they all blamed him since it's already hard enough to find Muzan."
'Damn, she's real cute. And Mitsuri is here too, they're much cuter than what I expected, at least a few times cuter than Earth's models.'
"I see, so he became afraid to tell people about his fight."
"Alright, you can go, my child." Ubuyashiki probably knew he couldn't get more out of me, so he gave up.
I stand up and cover my eyes again to go to the butterfly mansion since they still think I'm injured.
A few hours later, we arrived at the mansion and Shinobu came with us too.
"And Murata-san, it seems like you're completely healed, that's rare considering your injuries when you were first here."
"Yeah, they told me that I had a surprising regeneration speed since birth."
"Can I take a few drops of blood for research? I kinda want to know why you regenerate this fast."
"Sure, a few drops of blood won't do anything."
"Oh, and by the way, you'll go to your next mission tomorrow." Shinobu said as she collected a few drops of blood with a needle.
"I see, I kinda wanted to rest here for a bit" I said with a disappointed face, but it was true since I wanted to see Shinobu longer
And as we were talking, I realized that even if my body becomes strong, my mind will remain kinda dumb, talking to Shinobu made me realize that.
'System, can I buy something that'll give me a better IQ and a stronger mind?'
[ Of course that is possible, you can eat a pill that'll upgrade both your mind and IQ.]
'How much does it cost then?'
[ 2000 coin for the best tier.]
'I have 4000 coins left, so if I buy 2 of them, I wonder if it'll have twice as effects.'
[ Yes, host. Since this is a pill, not a skill you can buy only once]
'I should buy 2 of them since I am already strong enough to one-shot Muzan with my last purchase'
[ Mind strengthening pill (Peak Tier) 2x bought]
"Then, I'll go take care of other patients, Murata-san, don't forget to rest although you're already healed, building your stamina would be the best since you will go to your next mission tomorrow." Shinobu said as she left and closed the door.
On the other side of the door, a woman with butterfly-decorated haori could be seen blushing heavily.
