Demon slayer: Blood of the Demon king

Part 10-Inherited Memory

(Yamato pov)
I woke up in some kind of forest that was surrounded by bamboo. I was looking around trying to figure out how I got here.
The last thing I remember was passing out from my injuries fighting Doma, the upper-rank two demons of the twelve kizuki.

I didn't know what is happening, all I know is that this has to be some kind of dream or something. Cause when I first got here, all of the pain I felt was gone and my clothes which were torn up and destroyed were fixed as if nothing happened. The only thing that was missing was my katana, which wasn't on my belt, and even my haori was gone. But I continue to try and find a way out of this.

As I was walking in the dead of night, I sensed an aura of hatred and death in the distance, so I immediately ran to the location, and when I got there my eyes widen at what I was seeing.
I saw muzan kibutsuji, the monster the demon slayer corps has been hunting for 1,000 years, and now finally we meet face to face, before I could try to do anything I noticed someone else standing right next to him.
It was a woman in a purple kimono with flowers all over, which made me confused for only a second until I realized that it was Tamayo.

I remember what she told me when I first met her two years, she explained why she hated muzan with a passion. Muzan tricked her into becoming a demon when she was afflicted with an illness when she was still human. He told her that if she becomes a demon her illness will be cured and she'll be able to be with her family and she agreed, but what he didn't tell her was that the transformation has consequences which he intentionally kept to himself until it was too late.
Tamayo ended up devouring not just her family but other people as well during her first time as a demon.
And when she learned about what she had done, the guilt caused her to spiral into a void of depression and self-hatred for herself.

Even as time passes, she still carries that guilty of what she has done even though Yushiro and I have tried to help shoulder that burden, she would always refuse, saying that it was her burden to carry forever.
When I was about to try and make sense of why both of them don't acknowledge my presence. I felt a strong and very powerful aura right behind me.
I turned and saw a demon slayer, but in an attire similar to mine but a little bit different.

He was a tall man with black hair wrapped in a ponytail with red tips on his bangs. He was also wearing a red haori with an orange-colored nagagi kimono with a black umanori hakama, he was also wearing a pair of hanafuda earrings like me, and on his waist was my katana, which is in his possession.

Muzan:" Another one, I have no interest in swordsmen that use breathing techniques."
I looked at muzan with caution, and when I did, my eyes widened at what I was seeing.

I was seeing through his body, just like I did with Doma, he had seven hearts and five brains moving all around inside of him.
I watched as muzan attacked first by morphing his arm into some kind of tentacle-like whip, the mysterious slayer managed to dodge the attack and then proceeded to make a counterattack by using a breathing style that was all too familiar to me.

I was completely shocked at what I was seeing, muzan was defeated easily without so much effort by the slayer that used a breathing style that I know all too well. It was sun-breathing. I was shocked to see someone else using the breathing style. The sun-breathing technique is so powerful that no one else can use it due to it being too powerful for their bodies to handle, the only people that can use sun-breathing is myself and my siblings tanjiro and nezuko, my adopted father Tanjuro who passed away two month ago after moving my family to the demon slayer headquarters.

But then I remember that there was one other person who can use the sun-breathing forms, its very creator from the Sengoku period and that's when it hit me, this demon slayer is my ancestor yoriichi tsuigikuni.
The sun-breathing technique has at least 12 forms written down in the tsugikuni journal which I have read during my training under the former hashira's, but there was an indication that a 13th form was created, I just couldn't use it since I don't know how to. The book mentions that it exists since yoriichi used the form to cleave muzan into pieces. But after seeing it for the first time at a glance I finally understand how the 13th form works.

I watched as muzan tried to keep his head in place by using his now severed limbs to try and prevent it from falling with a look of confusion on his face over the fact that he wasn't regenerating.

I watched yoriichi looking down at muzan and asking.
Yoriichi:" What is the value of life to you?"
Muzan didn't answer him as his face began to turn red with anger and Tamayo who was watching from the sidelines didn't bother to try and help muzan, instead, she had a glance of hope in her eyes as muzan was about to be killed.

As Yoriichi was moving closer to finish off muzan suddenly his body exploded into chunks of flesh that scattered and caught Yoriichi off guard as he cut some of the chunks, but not all of them. As muzan manages to escape, Tamayo kneels in anger while crying because muzan got away and how yoriichi was so close to killing him.
Tamayo:" I wish that filthy man had died!! Muzan kibutsuji!!"
Tamayo looked surprised at the fact that she wasn't dying from the curse that muzan placed on her when she became a demon.
Yoriichi would then ask Tamayo about any information on muzan that would help take him down, she began to tell him everything about muzan and the fact that he would not appear to him again after what just happened.
Yoriichi let Tamayo go free, but not before asking for her help with taking down muzan she was hesitant at first but agreed to help, suddenly the area started to turn white as I began to feel myself drifting away until I heard a voice calling to me in the distance.
" YAMATO!!"
