[@Emeth]: Okay, so the big issue here is the Contract. It's very weak, and works entirely like a technological weapon. It also doesn't really have any relation to a supernatural entity at all, which is an issue since that's where the powers are coming from.

I'd aim for a fairly significant power boost and tying it closer to a supernatural entity. Additionally, the Contract is probably the most significant part of a character's backstory, so I'd like to see some more detail on how it was formed.

[@Riffus Maximus]: Hmmm.

To start with, I'm not really sure why she'd be taken all the way to Japan when it'd make more sense to enroll her in a local DDF Academy and later a local department?

And her contract abilities are [i]really[/i] underpowered. C-rank is supposed to be where, at least from a raw abilities standpoint without considering your experience or skill, you're capable of seriously taking on typical demons. Even if she was more utility-focused, it's all too vague and seemingly ineffective for that purpose.
