The show only has three main characters, it only has 12 episodes, each episode are only an hour long, I'm sure you could get 4 episodes on one disc,
Please be aware that I work on the principle of 4 to 5 episodes per disc depending on the length of each episode, so usually 4 per disc, like I said the show only has 12 episodes for this season therefore 4 per disc = 3 discs.
Plus if you look in the artwork section, yes there are quite a few images for this show but the pictures are only of the three main characters.

Anyhow I've done a fourth disc, but please keep the above in mind
