If Chyanne has difficulties to find her place it's maybe because after Tash's adoption, her role as DAE seems duplicate, maybe there's more room for a DSD...

I don't like to mutilate more my poor girls... but when running inventory, I already have lot of DAE, and few "pure "DSD, (only Linea in fact and she's quite busy in the bdsm role). Maybe it's what was blocking Chyanne's progression ?
