Well, let us begin?
First we have the silent strong female protagonist, Pasig Bluefield Ace.

Next we have precious cinnamon roll Domino Ace.

Allow me to give quick explainations.
These are their battle forms if you would, or if you're feeling angsty/edgy, what they look like when they lose control.

Starting with Pasig, she has eight magical cards that allow her to call upon eight burning spirits to do her bidding. But sometimes they're just not that useful in certain situations, and if she can't master the willpower to control them separately, they will become one with her. Not only giving her six extra arms, but intense battle magic. Of course she can't control this form very well, and will almost one hundred percent of the time end up injured in some way or another when she manages to gain back control or passes out.

Then we have Domino, he went through quite the change didn't he? Well, on his neck is a pretty little pendent holding his cape on. It was an enchanted pendant, and one he can no longer take off. But with it he can turn into the creature above, himself he was a hybrid, an anthropomorphic ferret with magical properties since little bits of him floated away. But if he lets the pendent take control, or his life is on the line, he will turn into "Big Brother" A true ferret, well, a demon ferret to be more exact. A very big demon ferret.

Eh, that's all.
