Originally, this was going straight for the Weird Questions section, but since you mentioned the universal problem of all human beings - no money - instead of just demand to know where you can download things for free, I'll take this a little more seriously :P
It would be a lie to say there are no places where you can download MKR stuff (or Anime in general) from. I'm sure if you look hard enough, you'll find some places that have them. Yes, they're illegal, against copyright and should be shutdown so I won't tell you where to find them even if I knew. It's really like any type of contraband (like drugs), if there's a demand, there'll be supply. So the "official answer" is yes, you have to buy them.
As for the "it's too expensive"... Well, Anime is entertainment. It's a luxury, it's supposed to be expensive (the non-Japanese releases are already much cheaper than their original counterparts). There's no way getting around it. If you can't afford the cost, then too bad, you'll just have to pass.
It's really a question of moral and ethics. Play it the "right way" by buying or going the "cheap way" by downloading, it's your choice and only you can decide for youself.
