Unknown to CYOC, there was another spirit very similar to him already in the world, changing people at random. This was a female spirit named UBEA and she favored turning males into females, more than anything else, and particularly liked the new females to have large breasts. And she did not take kindly to someone else meddling in her affairs.
At the moment, though, she decided to not take action, as most of the changes CYOC had made so far were not male-to-female changes. But she was keeping an eye on him. If he started to make changes that were similar to her own ... well, then she'd have to confront him. She was younger than him, but she might have been just as powerful. She was certain that she could easily deal with him.
