It's been quite awhile since we last saw a ZASH in The Reborn... way back in chapter 37. I did use it in MDJ a little after that.
In other news, I've moved Yes Princess! to it's own site: http://yesprincess.butterscotchcomics.com/ The third adventure was written for 24 hour comic day many years ago and it's now non-canon. It was never included on the main YP! archive on Smack Jeeves, and I think a lot of people never read it. It's pretty fun, imo.
