She’s like Caster, Kuzuki, and Lancer among a couple others where she fulfills her role just fine in SN and is allowed the benefit of her HA screen time to build her up to a point where she’s comparable to the rest of the cast. The criticism that she could still have done more is still kinda valid since she is a part of Sakura’s character and they could have emphasized it more, but Hollow is a good bandaid.
