Hey [@Lucius Cypher], glad to see Inspiration finally found you xD. 

I have a few things I need to work out with you, though. 

Firstly, Fran. I like the idea for a character like that and can see a few scenes with her but I'm worried about how you're going to weave her into the main plot unless she's supposed to die at some point for some reason. If not, she might need to find a reason to join the crew on the upcoming rescue mission. Either way, those are things for you to consider and think about. My characters could meet her easily enough but as she doesn't sound like a very serious type, I'm not sure how far they'd go (in the sense of friendship 'n stuff).

Anyway, to the point. 1.She needs pants. That's a must, otherwise we're completely changing the tone of the RP. I get that she won't like them, but she'll need to wear them anyway. Gomen. 
2. Shapeshifting - while this is fantasy, it's a magic realism sorta story so changing her size to that of a building is unrealistic. It's cool but if you want it to work you need to find he energy and matter to let her grow so far. I know Merlin had some info on how we established those things worked in the previous season so you can PM him. Getting smaller is easier as it's giving energy and mass away.
3. Why do her illusions work with kisses and not just with a touch? Aside from the fact it would be more dramatic and rom-commy that way. Again, a matter of realism. (you might notice but I try to steer well clear of the anime genre)
4. Holy lock can't possibly extend "infinitely" so think of a limit. I'd say 1-2 km max sounds reasonable. 
5. The axe is too heavy. It's impressive but succubi aren't really very strong demons so you will need to downgrade a bit. 

Donny is a cool character which, again, I hope you can weave into the story. I love the parts about his driving and his reflexes due to games. xD The problems with him are two. Firstly, even if he's immune to fire, he can't be immune to lack of oxygen or smoke as those are connected to the lungs and other internal organs and not with to the skin, as an exterior shield. So yeah, get rid of that (shouldn't have an impact on his worth) and secondly, the knife. I'm ok with it causing incurable wounds OR curable ones, but you have to settle for either one. With his skill, it's not a matter of your own will how the wound will affect another being once it's inflicted so you can't go back and forth. He can learn to use his essence in a way that makes the wounds curable or not later on perhaps, but to start with it's too advanced and more in the realm of controlling others than simple enchantment. 

I think this covers it... let me know when you make the corrections or if you want to discuss alternatives. :)
