These are Hair Fits for Ken1171's free A3AD figure (Madoka) and Studio Maya's Freebie Hair. Links for these models are in the readme. This set also contains Fits to position Anime Doll's Eye Props to Madoka. They should be parented to her head.
To use the eye fits, load Anime Doll, unparent the eye props, remove Anime Doll from the scene, parent the eye props to Madoka's head and use the Eye fits.
Depending on the software you use, you may have to zero Madoka for a perfect fit.
Happy Rendering :)
