InuYasha Fan Fiction ❯ Looking for a story ❯ 1 ( Chapter 1 )

So Basically I'm just trying to find this story since it's been on my mind lately and i want to try and find it so if you have any idea of the tittle name or author who wrote it let me know please! The story was about inuyasha and the gang in the feudal era and inuyasha's son comes from the future to help them with defeating something then there's this whole mystery about who's his mother kagome or kikyo but Inuyasha's son won't tell any of them
