There will be these ships in this story
Sanemi x Giyuu
Shinobu x Mitsuri
Genya x Tanjro
Either
Daki x Nezuko or
Kanao x Nezuko I don't know yet
Tengen x Rengoku
Inosuke x Zenitsu
Obanai x Muichro
They do remember there past life but can't see it very well I am talking about all the characters Muichro does not have memory lose but he does remember his brother clear as day and they were born together but he is emotionless. Obanai still has his mark across the face except it's wider and bleeds really easily. Ages of obanai and Muichro before y'all attack me
Obanai =17
Muichro = 16 (he's turning 17 though so their a few months apart)
Yuichiro ( don't know if I spelt it right ) is still a demon and lady Tamyo is still alive she wasn't killed during finally battle but everyone though she was. She only ran away as soon as finally battle was over she helped defeat Muzan.
