I understand, Mystic Breaker will likely just end up acting like a Familiar until such a time comes when he can be used to his fullest. That said, he is still able to inflict basic physical damage, and invisible magic sword-dogs do have their uses outside of fetching the daily paper.

The reason I gave Break such a power is that I thought it might be amusing to give her the one ability that counters her Prismatic Dream in all of its entirety. Oh right, I had a bit of a question regarding transformations, do MG/MB transform to use their powers? Regardless, can they use both aspects of their powers in unison? Lastly, what state were you intending this roleplay to take place in, relative to the growth of our lovely magical girls? Are they newly developed, perhaps having formed their contract only recently, or did you want them to have been doing this for a short while?
