Guilty Gear Strive: Some New Millia Mix-Ups
These are some mixes and set ups I found across YouTube. After raw disc hits, do jump D, DELAY J.s, J.s, C.s, then after the close S, jump and air dash twice to get a cross up on their wake up. From there, you do J.hs into whatever. Another mix you can do is Mirage cancel into H Disc after a sweep, for some left right shenanigans!
