Bait: She's set up to be a Good Parent and a Nice Girl, but the endings show she's anything but.
Big Bad: She turns out to be plotting to kill the villagers and is manipulating the protagonist Ryo into sabotaging the Harvest Festival so she and her "friends" can eat them.
She is extremely good at appearing as a loving mother instead of the evil
Crow
