Eh, this was pretty amusing. I do appreciate that you at least tried to give the Girlchan series a proper ending. Just like you, I also grew up watching it as well, and always wanted to see how exactly the series would "end". Although looking at it, I suppose it is kinda funny how Kenstar basically tried to make the 4th episode himself only for it to end up being deleted, which probably does "EXPLAIN EVERYTHING".
Edit: Now that I think about it, maybe it was perhaps Galacticamaru who got the final episode deleted. Because he knew that if the final episode got released, therefore signifying the end of the Girlchan series, he would be defeated, so he sabotaged all of Kenstar's work so that he couldn't be defeated. ..."THAT EXPLAINS EVERYTHING"!!!!
