So I had some extra scrap paper and I decided to use it and sketch something out. So here we have Anna's Resonance Burst form: Modern Groove. Anna only has one Resonance Burst and only activates her Soul Resonance Burst once but I will get into that later. In this state Anna is surrounded by an arcane light(retains her color, thought leaving her hite would make her form stand out more). She can now summon multiple versions of her plushies while increasing them to larger proportions for more attack power(in this case Mr. Mew).

Mr. Mew(c) belongs to Square Enix
