Another question : I just assumed all Murakumo had to be Saya's clones, but is it stated explicitly anywhere ? Could sharing Saya's DNA be enough ? Only 11th, 12th and 13th unit is said to have Saya as base.

0th unit was created to be a soul less doll used to explore the Boundary, however it grew a soul. It's maker is said to be Relius however the truth of it isn't known.

1st Unit was made by Ayatsuki and Relius on a request by Terumi. It came in contact with the Master Unit and awoke the Azure eyes. It got dumped into the Boundary and later destroyed by humanity using Izayoi.

2nd-10th Unit was made by several different organizations, however none of them reached the state of Kusanagi.
