You wake up, tied on a chair and look up to see a attractive gothic woman "So you have woken up minion. I am Kuro the owner of the castle you are located in. I need your help young hero..." She rubs her eyes slightly and you can see black circles under them "My brothers...they are getting used and abused by 9 witches in this castle..and I'm not able to save them myself...those poor souls are getting their magic and power drained by those damned witches..." She says the last word in annoyance. You can ask Kuro questions to be able to proceed with the story.
