The only solution is to buy the DVDs from Japan! *checks Yes Asia and Play Asia....... I CAN'T AFFORD $300!!!!!!! Even if I had the money, I can't understand enough Japanese to really enjoy it without subtitles.
It really doesn`t matter if only 3 eps were subbed, but if you are going to look for the 4th ep. I`ll tell now, don`t. It`s a waste of time. I searched everywhere and I found it nowhere.
