Izao and Reiko have long since decided that they are brother and sister, there will be no relationship between them, if that's what you mean. I decided to start writing on behalf of the rest of the characters, because they will play an important role. I think someone has already guessed who the third character is. He will appear in the next volume. This one will be entirely dedicated to the Kuchiki clan. The first volume will have about 20 chapters, maybe less. Each new volume will show one character or a hint of the next or the next, not the fact that the character will necessarily appear. And yet, do not trust my answers or hints, because I could have deceived. Recently on another site I was asked whether the characters (mine) will influence the plot or they will just watch, I answered, here I decided to answer in advance. Yes, they will. I also wanted to say right away that the world in my fic may not correspond to the original.

They look like five year olds. My mistake is that I missed this point. Until the age of five, souls born in Soul Society grow like ordinary children, but after five they will grow for a very long time.

I would be glad if you could help me with one solution. The story mostly comes from Izao's perspective, but there are also other characters that will appear in the future. Should I show them and write on their behalf, before they all meet? Thanks for reading

If you count after rebirth, then 4. But if you combine their lives before that, then approximately 27-Izao, 25-Reiko
