The Lost Sparda (kimetsu no yaiba x male sparda's descendant reader) [On Hold]

Prologue

Sparda:You know I have to my son. It's for your own safety.

Y/n: I know but you're the strongest demon in the underworld, you defeated it's entire army and it's ruler all by yourself, are sure you have to go?

The boy was insistent having his father stay but little did he know that his father was dying. Centuries without his true power and physical strain of sealing the two worlds apart caused him to be weakened drastically and left to slowly die. He doesn't when it will happened but better safe than sorry.

Sparda: I know this is hard but please understand my enemies will do anything to get to me even kill the people close to me and my presence here is nothing but a beacon to them to attack you and your mother so for both of your sakes I must leave.

Sakura: I know it's hurts Y/n, it hurts for me too but we must grow from this.

Tears start to swell up in the boy's eyes. He knows it must be done but he can't help but sad about his father's departure.but before he starts to cry fully he wipes the tears from his eyes and puts a brave face on.

Y/n: Alright,but you better visit us once while. Mom will get lonely if you don't!

Sparda:* laughing* I will, I promise.

At This moment a horse drawn carriage appeared at their residence signaling it was time to go.

Driver: Alright, are you ready to go sir?

Sparda: In a minute. Alright, my ride is here better get going!

Y/n: Wait! What about the Rebellion and Yamato you're not taking them with you?

Sparda: No, they're yours to keep but only when your mother says the time is right!

Y/n: But Daaaaaad?!

Sparda: No buts! Your mother will give them to you when you're ready.

Y/n pouts about not getting the swords right away but immediately stops when a hand smacks him across his head.

Y/n: OOOOOOwwww?!

Sakura: Behave.

Y/n: Okay!

Sparda laughs at the sight and starts putting his bags on the carriage. After he's done putting the last bag, he returns to his wife and son for one last goodbye.

Sparda: Alright, I'm off. Goodbye, I love you both.

Y/n: Goodbye dad!!!

Y/n hugs his father one last time and he melts into his father since it maybe the last bit fatherly affection he'll have in a while. He lets go after a good while with tears swelling up in his eyes. Sparda then moves to hug and kiss his wife and he tells her one last thing.

Sparda: Y/n's demonic heritage will also be a beacon for my enemies but his power is currently sealed and it won't become undone unless there's strong, emotional trigger. You must look after him and make sure that doesn't happen.

Sakura: I know, I love you.

Sparda: I love you too.

After all that love and affection Sparda finally left on the carriage Y/n and Sakura waving goodbye with tears eyes while he leaves until he was finally out of sight.

Y/n: I'm going to miss him.

Sakura: Yeah, me too. Come on we need to ready. A family friend is coming by later today.

Y/n: so soon, dad just left.

Sakura: I know but it was last minute so come on your father wouldn't want to be sad right now. Plus I heard they're bringing their two daughters with them so you have friends to play with. Maybe one of them will become more than friends with you!

Y/n: Moooom!!

Sakura: you're right, both of them will probably fall for!

Y/n: Moooooooom!!!!

Meanwhile

Sparda: my son, they'll be a time will be a where you reveal your heritage to protect others I hope that never happens but be ready. My story is over, now it's time for yours.

________________________________
And done with the prologue, what do you guys think this is my first story so it's a little rough but I'm satisfied. Also the reason for why he's dying is in the story is personal head canon on why of died. I mean you're telling losing your power and sealing a separate dimension would put a strain on you. Well I'm out peace.
