After the fall of Zovaal the jailer, the border between the Shadowlands had been closed, as it should be. The Winter Queen of the Night Fae had found an anomaly in her forests and had called one of the most powerful beings in her covenant to come help her, even though she knew it would be very hard to send the mortal back where she came from.
Little did the Warlock know that she'd be sent to an entirely different universe from the one she knew with no way back. With being a child again and having no knowledge on how this world filled with chakra instead of mana worked, she was screwed. But she didn't get to where she was in life by shying away from difficult things. The only thing she could do now was to make a life for herself in this new world, and maybe, just maybe become one of the most powerful ninja alive while she was at it.
