You got it right this time.
I never thought that giving it titles other than listing the show's name and the volume was all that important... though if I were to name them:
1. Raging Heart
2. Rival
3. Allies
4. Redemption
And they need to release it with four episodes on the first dvd (its gonna suck if they stop at three, seeing as how the first three episodes were typical magical girl crap... I've ran into a few people that gave it a chance and were turned away by the first three episodes being exactly what the show title suggested they are) and three on the rest, IMO.
