hey to answer your question um... each girl except Washu, programed the 
machine to create there own worlds. instead the machine went haywire and went 
to Ayeka's world. Washu has to fix the machine in the order each girl 
programed it. first she distroyed Ayeka's and it went to the next world until 
they were all deleted until it got to Ryoko's and Ryoko had to leave her 
world to bring Tenchi and all the others back to the real world. does that 
answer your question?       ~rigglegiggle~
