Optanjiro Stories

What if Tanjiro was op from the start

Tanjiro was born a child prodigy, just like Yoriichi himself. He had the mark when he was born, from the top left of his forehead with a fire pattern. His father had taught him Sun-Breathing from the young age of 5, and he had mastered it when he was only 8. He has access to the see-through world and selfless state when he is 12. He is yet to unlock the 13th form, as only Yoriichi knows it for now. Little did he know that one day his peace would be stripped away, from the smell of blood... - WARNING: This contains:- - OP Tanjiro - No ships yet - Cringe? - Dead Nezuko AU -Don't judge me too hard, this is my first story :')-

What if Tanjiro had a natural demon slayer mark he was born with? What if that mark didn't give him incredible strength, speed, or agility, but did something else? What if Yorrichi hid his blade in a cave on the highest peak of the Kamado family's mountain? What if Tanjiro learned the Hinokami Kagura from a young age? Those are questions we don't know the answer to. The timeline is a strange thing. Just one change could alter the fate of humanity. So what would happen if all those questions came to fruition?

Tanjiro comes home to find his entire family dead. He was later found by Giyuu and was sent to Urodaki to train to become a demon slayer. But after he got their he got dreams of someone with hanafuda earrings(Yorrichi) performing a breathing technique he heard him call sun breathing that looked very similar to his family dance. After he told Urodaki about this he immediately told Tanjiro about sun breathing and that only one person was able to do it. After seeing that Tanjiro cam actually use sun breathing he immediately told him to train and train more in this breathing technique. Over the next two years Tanjiro would get the same dreams and has learned how to perform the 12 moves flawlessly and is still training to do the 13 form. Read the first chapter for more information.

A fanfic where Tanjiro is a descendant of Yoriichi Tsguikuni but he is more powerful than Yoriichi and Kokoshibo combined, but Muzan is just barely stronger than him due to his demonic enhancements and powers. Rated T for swearing. Once this story is complete, anyone is allowed to make a characters react to this book fanfic but not more than that.

So in this Tanjiro has the Ability to Tame Demons. And he's the reincarnation of The Demon Tamer

My first book read it to find out what happens Ship: tanjiroXshinobu

What if Tanjiro knows how to use all breathing styles? and a harem.. hashira's, demon slayers, and even demons will fall in love with him what will happen? read to find out~

Muzan comes a slightly earlier than before to kill the kamados and he has the genius idea of turning them all into demons. Too bas none survived the transformation, Or Did They? this fanfic is the definition of "Fine, I'll do it myself." though most of my ideas are. I DONT OWN DEMON SLAYER AND IT BELONGS TO ITS RIGHTFUL OWNER. Note: Updates might be inconsistent due to me writing a lot in a single chapter and school and stuff, its not discontenuied or abondedned if i dont specifically mention it being so. it wont happen that often anyways but im nearing the exam season so.

What If Tanjiro lost everything ? What if Tanjiro created his own breathing style? What if no one came to help him ? What if nezuko was dead ? What if tanjiro was like muichiro ? what if tanjiro was lonely and had no team ? Join tanjiro on his journey on slaying demons ...

Countains manga spoilers. After beating Muzan, everyone was... Delighted. "Wait! Tanjiro!? Is he fine?!" Cried Giyuu, Water Hashira. Although some Kakushis tried in vain to calming him down and avoid moving, but he did not listen and rushed to a young man on the ground with one arm less, Tanjiro. Giyuu lowered himself to his level trying to see if he was awake but no signs. The Water Hashira began to panic but a few seconds later, the boy who was unconscious raised his head and opened his eyes slowly. But... instead of his usual dark red eyes, they were crimson eyes with pupils like those of a feline, or... pupils like Muzan, the now dead Demon King. "Tanji...-" Giyuu did not have time to express his shock when the boy he had previously saved, made him lose consciousness. The new Demon then took the opportunity to jump to the highest point of the building and became acquainted with the place. After a few moments, he whispered "Blood Demon Art: First Form, Fukkatsu*". A blinding light followed can after the end of the incantation. Fukkatsu*= Resurrection ---- This is an AkaTan AU, so if you don't like the ship, please don't read

Anime. The one thing that Ryan felt made him normal. Even then he wants to live as the average person. Sure having your parent's multi-septillion fortune (18 zeros), an intergalactic business empire that supplies weapons to the military and the trailblazer in medical tech and own solar systems as private property is the average rich guy shit. Well, Lil MISS Fate decided to say "GET UP BOI" so now he has to worry about four MC's from four different anime, help them get back to their world and possibly ,y'know, stop their fated nemeses from conquering them coz why not? WHAT COULD POSSIBLY GO WRONG?

Tanjiro Kamado lost everything and yet doing what he's doing, he never felt more alive. He may not longer be exactly a human anymore or even a 'good person' but for the memory of his family, he will slay Kibutsuji Muzan and everyone who'll get in his way and he may just get a daughter along the way. ------ Will add ship tags as the story keeps going

This is my first story so if you guys found any mistake in it then I'm very sorry for that. Reminding: I do not own KNY and it belong to Gotouge Koyoharu. This story is about Tanjiro who is the eldest son of the Kamado family who use Sun breathing but no one know about it because they never use it in fighting and it has been passed down generation to generation which is know as Hinokami Dance. After his family died (just like manga), he and his sister-Nezuko (which was out and staying with her neighbor the time their family died) meet Giyu and he instruct them to his master-Former Water Hashira Urokodaki. Now their journey begin.

What if- Tanjiro was a descendants of Yoriichi heavily inspired by @SpiderNerd13618 Title : Demon Slayer : The Rising Sun

Michikatsu tsugikuni was turned into a demon sgainest his will by muzan as revenge for yoriichi almost killing him. Kokushibo now dwells near to the kamado household's, who were friends with yoriichi. In this AU of demon slayer, let's see what happens

Sabito was awakened by a hard slap. He perked up in surprised only to meet the presence of the strongest Demon slayer members. The Hashiras. But he didn't care. All he cared about was finding his demon best friend. "Giyuu?!"
