|Black Witch Oya|
- "It's the same mentality as when you became a pirate. There's no one that can hold me back. That's FREEDOM. I used to think the strangers are adults. Not anymore. We'll see if this world will remain after I scratch it up with my nails."
- — Black Witch Oya
[Limited Heroine Card] Oya is a princess from another world. She went looking for the person who summoned her here, and when she found them she forcefully took the magic item that had summoned her. She plans to take over Sanctum and bring chaos to this world.
