The next chapter is isn’t really canon anymore. I drew it for the 2007 24 Hour Comic Day, so it was actually drawn several years before the previous chapter. This chapter was never included with the main YP! comic on Smack Jeeves, so I don’t think many people read it. Still, even though it’s not really canon, I wanted to include it here 🙂
Yes Princess crosses over with The Reborn, starting with chapter 20 of The Reborn.
