What if tanjiro had cremation part 2

In the video I had tanjiro make a new breathing style and it took almost 2 years. He did not miss the deamon slayer exam so don't worry. I even gave a description of one of the creameation style to look like sephiroth sword by the length of it. Also I don't own final fantasy 7 or anything to do with final fantasy series. So I hope you enjoy the video and this is a none paid video.
