Okay, so since I'm done sorting stuff out with uni (just got to wait and pray now, ahah), I can get to work on assessing character sheets. I'm going to post this as I go, so if your character's not here, I might edit it in later. Or put it in another post. Just doing this so I don't end up losing the stuff I've written up.
@Yandere Noodle: Firstly, I think I need a bit more than a short quote for the personality section. Secondly, I'm a bit hesitant on all the "super effective against demons/undead" stuff since demons are...well, they probably have a bit of a tendency towards darker personalities (not to say all demons are chaotic evil...or even evil in general), but...angels and demons aren't meant to be representations of good and evil in the RP, they're just things that exist and undead...well, unless it's due to a contract like a bakeneko raising corpses as zombies, any zombie/vampire/etc isn't really undead, they look human and might have traits associated with corpses (zombies looking like rotten corpses, being cold to the touch, having no breath/heartbeat, etc) but they're still "alive". Finally, the previous point aside, I'm really not sure about that resistance ability for the summon. Since, if I'm reading it correctly, it's basically saying if the opponent's a demon/contractor using a demon's powers, she can shrug off anything, even if it should be a lethal hit with no injury whatsoever, which would come under the "no selling" bit in the OP, I'm afraid.
@Enigma: Well, firstly and mostly just as a terminology nitpick rather than an actual problem, I think a kitsune would be a youkai, not a kami. And, more out of curiosity than anything, why are a Japanese spirit's ability names German? As for actual issues, I'm a bit confused as to why you didn't use the character sheet in the OP (although as far as I can tell, the only things you haven't got equivalents for here are the optional backstory field and clubs, which I guess could just be a sign that the character's not in any?). I'm afraid that "can bend light to her will" is a bit too vague for me to accept, since while that could just mean bending light to create illusions, it could also mean the opponent's now in a tiny sphere full of laser-y death. Also, 10-15 minutes...is actually quite a long time. I'd be surprised if a fight lasts more than 5-10 in-character and...honestly, I'd generally put 8-10 as a limit on how long a summon can go all out without needing to return to the other world. Also, are Raum and Trick based on anything kitsune are known for? I mean, I know they do illusions, but I'm curious as to whether or not there's more behind Raum's execution.
Those things aside, they both look like they could be fun characters.
Um, sorry to everyone that's still waiting. Like I said, I will get to other characters. Just not right now, ehe.
