(mc pov)
Today wasn't a typical morning... No today was the day that my journey officially begins it was the day of the test to become a demon slayer I still wasn't sure how much I should interfere, especially at the start.
Why? Well it's cause the fights tanjiro goes through especially the one with the hand demon is essential for his growth and well I'm not exactly the strongest yet And neither can I tell the future.
This is important cause if I help tanjiro too much he becomes weaker than in the canon, and if I'm not strong enough by that time muzan will win. Those reincarnated or other people mess with the protagonist who will potentially save the world.
If your strong enough and have the best cheats then yes you are not really bound by any rules, but me? I don't really have much except for my knowledge(and even that is very limited)... And after some point I'll have no knowledge of the future which is scary and at that point all I'll have is my useless system...
Anyway, onto the next topic I have been making a breathing style of my own I call it space breathing correlating with lightning breathing since both focus on speed and catching the enemy off guard.
I've only created 1 form - space breathing: instantaneous movement - and as you can tell it is more of a escape move than a fighting one where I can move almost instantly, does this make my lightning breathing first form useless? No. Why? Well the answer is kinetic energy.
When I move instantly I carry no momentem which I consider a downside as the first form of space breathing may be faster but it definitely doesn't carry much force.
"Zenitsu!"
Oh it seems gramps is calling me again well guess I have to go now.
(Third person pov)
As Zenitsu approached jigoro, he looked at Zenitsu proud of how strong he had become.
"You'll pass I'm sure", jigoro said with certainty in his voice.
"Thanks gramps for everything you have done till now"
"Hahaha, don't give me this sappy bullshit
especially since you your leaving now"
"Well gramps I'll miss you"
As Zenitsu looked at the only person he considered family and the place where he had woken up at, the only place where he felt safe, with hesitant steps but a determined heart he set off towards the test area.

(Mc pov)
I finally reached the mountain and as I looked at the twin guides I couldn't help but wonder. Are they real? They looked like... Dolls? Yeah, what I'm trying to say is looking at them gave me the creeps for some reason.
"And with that the test begens"
Everyone around me ran to the forest with no westeria I on the other hand walked leisurely, I mean it was a test and no one was in any danger.. technically anyway as I walked soon a generic demon with the same generic lines appeared.
"Hmm food at last hahaha"
"Who are you?"
"I am yu"
"Not me you"
"Yes I told you I am yu-"
I cut his head off instantly.. what a stupid demon the least he could've done is told me his name, suddenly I heard a scream it sounded like a demon was chasing someone.
I instantly flashed by the demon and cut his head off.
"W-wow I didn't even see you" background character 1 said.
"Run why even participate if you can't fight or have a trick up you sleeves",I say as I walk away.
It wasn't that I wanted to look cool(totally) it's just that right now that guy I thought of him as a background character.. I'm still thinking of this as an anime huh I can't really think of all this as reality still I really need to change my mindset.
As I walked over to the distant sound of battle I saw the (famous?) Scene of tanjiro cutting the hand demons head and praying for him.
I obseverd for a few more minutes and left, not yet I wouldn't change anything till someone is seriously injured or someone is dying. I walked towards the end.
(Time skip u know the same as anime happen head bash happen basically)
I was walking when I stopped walking so my legs stopped walking and I stopped walking right that moment cause I looked behind and lo and behold youruichi junior he looked like how I expected him to.
"Yo aren't you iron head?"
"Who me?" Tanjiro said while pointing at himself with a confused expression.
"Well who would I be talking to but yea honestly what's your head even made of man"
"Umm years of work I guess?"
What did he bang his head to break down trees???
I looked at him like he wasn't human.
"W-why are you looking at me like that"
"You used you head to to do all your work physically instead of mentally?"
"What no hah forget it" tanjiro signed.
Suddenly his stomach grumbled*grrrr* he looked embarrassed Lucky for him I always carry food, I take out some dumpling and give him some.
"Thanks I'm tanjiro Kamado" he said while bowing down, what an oddly polite kid
"I'm Zenitsu Amagatsu"I say still lost in thought when suddenly a crow comes by and shouts at us to go to a demon well here we go I guess oh and did I mention the sparrow well I guess I'll save that for next time.
(End of chap)
A/N:Well guess that's it I know there's almost little to no interaction but that's cause I still have to get mc adjusted to the world anyway.
