"Lets Learn Japanese"

Ok so... I found these great videos of basic japanese learning. But the thing is that I can't find all episodes. There are 26 in total.

11 of them I found on an anime site (not sure if I'm allowed to post link)
Some more I found on youtube etc.
And I found most of them over torrents.

Now if somebody could help me find episodes let's say 20-26 since I don't remember seeing those anywhere I would be very grateful. Thanks in advance. ^^

Learning a foreign language is really hard--especially japanese. Good luck with the videos. I bet it would take about fifteen years to completely master Japanese. It would be a great attribute to reading authentic Jap manga.
