Harry Potter pov)
Since I got the Hallows I have been a god. I can make myself a mortal body, live and then "Die" like any other mortal, and I do that every once in a while. I know many things, like how you're reading about me through a screen, I don't keep track of everything mind you but I'm self aware enough to know that. You see I as a death God can not be bound in any meaningful way, but one pesky group of people found a way to summon me. It's quite annoying I must admit. You may know them as the Uzumaki. This is the tale of my meetings with those who have used the Shiki Fujin.
(Many years ago)
The first encounter I had with the Shiki Fujin was with the last Clan Head of the Uzumaki Ashina, he summoned me, before him no one has summoned me in such a unique way. The summoning technique was a masterpiece, the kind of thing only someone who was "Different" could make. "I summon thee, the great shinigami" he had said, and so I sat and talked, the conversation went something like this.
(Flashback)
"Well Mr. Ashina, or I suppose you go my Ashina-San in this world huh?" The red haired man looked shocked that the summon had worked, but my words snapped him out of it.
"So, you're the Shinigami?" He asked in a worried tone. I couldn't help but laugh at that.
"That is my title, yes I really do prefer to go by my name though. It's, hmm how do I say it in a way you would understand? Ah yes Hōmurūrā written as ホームルーラー." The man stared at me before he asked a question.
"So, now that I've summoned you, what happens?" That was a funny thought, I could have of course ignored the summon but I never thought about what happened after I would answer.
"What did you expect, Ashina-San?" The man said "I thought I would trade my soul for something of equal value, my death for the death of another, to be dragged into the underworld to fight for eternity." I give him a puzzled look.
"Well I could do that but I don't want to, personally I think I'd do what you said but instead of sending the people to the underworld I'd take them to my office and try and get them to settle their differences, I haven't had much fun lately." Ashina-San asked, "settle our differences?"
"Yes, I do have infinite time, so do the dead unless they wish reincarnation."
Ashina pondered that statement for a good long while. "That doesn't sound too bad, would you be willing to agree to do as you have said when this technique is used?" I scoffed at him and said yes. Little did I know that would be an annoyance like no other.
(End flashback)
Many, many years later I was summoned using the technique for the second time, it had been long enough that Ashina was surely dead, with a quick thought I found that yes, he was indeed dead, when I payed a bit more attention I found it was suicide. It was something that had shocked me at the time(I later asked him what happened, it turns out he turned himself into a fucking bomb and blew himself and everything in a 300 meter radius into "Nothingness" and took about 20 people with him in a bid to save his people)
(Flashback)
I answer the summons as I promised I would. When I entered the "Real world" I found myself in a field with a blonde, a redhead and a Giant fox with nine tails. I was of course quite confused, with the snap of my fingers I paused everything in the world except for me and the two humans next to me. "So, I am The Shinigami, why have you summoned me?" The blonde man startles.
"You, you can talk?" The man seems confused.
"I am a god, why wouldn't I be Able to talk? I am a very strong being with sentience who can alter universes. I must be honest I'm a bit upset with you, ah yes Namikaze-San." The Red head then says "Black hair and green eyes, so old man Ashina wasn't pulling a prank?" The red head exudes "Life" and it makes her quite easily recognizable as an Uzumaki even without looking at her soul.
"Ah yes, you must be one of Ashina-San's descendants. I am Hōmurūrā, it's written as ホームルーラー." The woman looks shocked as the writing of my name appears in her head.
"So what seems to be the problem here? I can't help but notice the giant fox." The blonde man chuckles "it got pulled out of my wife here." My eyes widened. I quickly look at her soul and see her life flash before my eyes.
"Wow, that is quite honestly scary, I must admit Mito-San is a true artist, this is a spacial-soul manipulation of the second highest degree I have seen from the art of Fuinjutsu. The best of course being Shiki Fujin." The woman smirks.
"Us Uzumaki are awesome like that!" Yes they really are.
"Well, I suppose I'll be back in a bit." I snap and suddenly they pause in time, in their place unfrozen is the Fox.
"Hey buddy, I don't know if you can speak since you don't have a soul but if you can, I'm The Shinigami."
The nine tails fox huffs and says "yes I can talk, I may not have a soul like those humans but I am sentient." That causes me to tilt my head, I check a bit deeper and find not a piece of a soul but an imprint, something like a copy. It's not really there, somewhat like a mold of a knife, you can tell what goes there even though it's not there.
"So, who created you, you're most certainly not natural." The fox growls.
"Aren't you a god, don't you know everything?" I give my honest answer.
"No, I could if I wanted to, I could know everything that wasn't hidden from me by another God. But I personally don't find that fun so I don't, I still know many things but this wasn't one of them, I had no idea you even existed." The fox sighs and simply says a name.
"Otsutsuki Hagoromo created me and my siblings, all nine of us." I search my relm for his soul but don't find it.
"Is he dead?" The fox snarls once more
"You are the god of death can't you tell you dumbass!" I snap my fingers and suddenly the fox has a muzzle keeping its mouth closed.
I search the world and find nothing. After what must be 100 or so years I find a distortion. I leap away.
Once I get there I find a white skinned man sipping tea. "Hello Otsutsuki, so you became a minor god then?" The man smile nicely
"Oh I suppose, not that I do anything with my powers, just sit and watch, free will and all." I tap his shoulder.
"Good man. So I'm gonna go now." I pop out and teleport back to the fox.
"Well your old man isn't dead, he did become a minor god though and has decided not to interfere." The fox startles try to speak, I snap away the muzzle.
"You mean I could see him once more?" I nod
"Yep, but first, I have a job to do." I unpause time and erase everybody's memories except for Hagoromo. I let the event play out before I grab the fox and the blonde and pull them not to the office but to an empty void with nothing but air and a black obsidian floor. Maybe letting them fight for a few centuries will actually help them get along. Talking sure won't do it with that old fox.
(End flashback back)
And that's how I dealt with the fox and the blonde. They have become fast friends since.
Now the next time I was summoned was really boring. I simply dragged them where they were supposed to go, then met with Minato and the fox, the four Kage as they are called just chilled and talked, sure they and the fox spared everyone and for a while things were good. Until they weren't.
But that is a story for another time.
