Optanjiro Stories

On a lonely, wind-swept road deep in the heart of Japan, a mysterious figure emerges from the drifting mist. His face is concealed behind a smooth, expressionless mask, marked only by two hollow eyeholes and a blazing flame emblem etched across the forehead. The mask gives away no emotion, making his presence feel both unsettling and otherworldly. He is dressed in a flowing black kimono layered over dark trousers, the fabric rippling sharply in the cold evening wind. Resting across the back of the kimono is a striking emblem of the sun and moon intertwined, stitched in faded crimson and gold as though symbolizing balance between light and darkness. His fiery red-and-orange hair falls wildly around his shoulders, glowing like embers against the night. At his side hangs a finely crafted katana, secured in a lacquered sheath. The hilt is wrapped in worn black leather, suggesting years of battle and travel. Guarding the blade is a unique tsuba shaped like a raging sun caught within the crest of a tsunami, blending fire and water into a single deadly symbol. Every step he takes is calm and deliberate, yet the air around him feels heavy with danger, as if the road itself fears the warrior walking upon it.

(I do not own the Demon Slayer) In this Story Tanjiro is born with a mark like Yorrichi and Tanjiro has mastered the Sun breathing and he's powerful as Yorrichi and Tanjiro will be related to Yorrichi and Kokushibo and Tanjiro and Yorrichi Tsugikuni are look the same in everyway. (There will be change's in the story) *Kanae alive* *Nezuko died* Tanjiro x Kanae...

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 ...

We all know that Muzan was turned to a Demon because of an incomplete medicine. Well, what if two others were given this medicine. And this time it was complete..? Just read the story -_-

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

what if tanjiro goes back to the past, after muzan is defeated tanjiro can't see anything and knows that he is in the past to save all the precious people around him. here for some reason nezuko here dies what really happened. all these characters are not mine, I just borrowed them.

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 didn't train with urokodaki And instead was taught by people from a different universe and became extremely powerful I do not own demon slayer or Naruto

Here we see what will if tanjiro is having the potential of yorrichi his strength his breathing style and other things we will see what will happen so let's continue in the story.
