You can use the other's suggestions but I highly recommend buying Funimation's Blu-Rays if you can for around $30 or £25 on Amazon. It supports the company and gives us a better chance of Funi dubbing the third season quicker.

If you can't afford it, definitely check around for torrents or download the eps individually from Kissanime (don't use Adblock on their website b/c it won't allow you to download anymore).

Here ya go!

Yeah, the reason you weren't finding it is because it's not on amazon.de . Enjoy!
