From what I've seen, everything can run pretty loose with posting order as long as people are pretty much active.<br/><br/>I'm not sure that a time skip would be a good idea right now because it might leave the "viewers" wondering wtf? I know some Anime tend to skip around a bit but with all the sudden weirdness some sort of stability might be needed. I suggest one of two things:<br/>1) an explanation as to how the book works or a letter from the grandfather eluding to where he got it or what its about (this could be more cryptic than an actual in-detail explanation)<br/>2) Some sort of "calm" so the girls can begin to integrate into his life. They're going to be going to school with him and everything so it might be a good idea for, say, Ty Dao to fall asleep while the other two girls get to know their master a little.<br/><br/>Of course, these are just suggestions.
