both alice and yanagi are on-field anomalies (yanagi can work as off-field but really only for miyabi)
that means they want 1 off-field anomaly and 1 supporter / defender
grace can be used as an off-field anomaly (together with seth), but piper is on-field (you could use yanagi as an off-field with piper and lucy i guess, but it wouldn't be optimal)
when playing anomalies, you want to cast a disorder, meaning 2 different elements. so alice + grace and piper + yanagi would cover that

i do agree with the other anon >>535796771 that yuzuha would be preferred for alice, as is miyabi for yanagi
but i mean it would still give you a power boost for sure, if you're struggling with cleaning things
>i just finished chapter 2
honestly, if you don't care for alice / yanagi in terms of looks, you should save. you don't need fancy characters to finish the story. none of the current banners are void hunters or universal supporters
if you really like how alice / yanagi look, then sure, roll them and build them slowly over the reruns, but as a new player there's no need to rush
