"You don't understand. You don't want my love. It's not a good thing to be loved by me.
I'm not as nice as you seem to think I am."

-Also known as the witch who cursed Kieran.
-Fell in love with him after he'd saved her life. He didn't think much of it, but realized that he could use her when faced with her undying adoration for him.
-Happily helped him gain power - at first, but started getting jealous when he started eyeing another girl. She eventually snaps when he announces the wedding, and curses him and his wife on the day they're wed.
-Now lives in a small forest, away from civilization. She can't bear to fall in love again. Not when she's still not over Kieran.
-Knew that he'd been using her, and yet clung to that small hope that maybe one day if she just gave him long enough, he'd love her back. When she was faced with the reality that her dream would never come to pass...she couldn't take it.
-She wasn't able to resist adopting a child that wandered into her forest though. She always did have a heart even if she denies it now.
-Spent most of her time nursing him back to health denying any attachments to him. Says she's only "letting him stay" because he has nowhere to go, but would absolutely feel depressed if he ever leaves.
-Knows that if she acknowledges how attached she's become to Miyu; she'll never be able to let him go. Too afraid he'll leave once he understands how possessive and prone to impulsive decisions she is. Still, she likes feeling needed. She's afraid that one day, Miyu's parents will find him and take him away from her. Or that he'll want to go back to other humans, and she's not sure how she'll react if that day comes so she tries to ignore it. Has the habit of overthinking a lot.
-Intrusive thoughts tell her she should kill him before he leaves like everyone else.
-She has black hair canonically but like the green kelpie mane is cheaper so what can you do. Also it fits her feral forest witch image.

Meanwhile Miyu; literally worshipping the ground she walks on, hates other humans because they were cruel to him, and would literally die to make her happy and hates seeing how miserable she sometimes looks????
