I have not played the source games of the following members of the Top 32
>Aigis* (I have played PQ & PQ2, but I assume that doesn't count)
>Morrigan, Lilith, & Felicia
>Marisa & Cirno
>2B
>Illya
>Tron Bonne
>Alice Liddell
>Jill
>Amaterasu
>Noelle
>Splash Woman
>Fio
>Ashley
but of course, good results have convinced me to play games in the past (OFF, Hollow Knight, Yume Nikki, Shantae, Deus Ex, etc.) so your main's success may change that.
