For starters, we never said we don't like the idea of her being a summoner. I even told you that's all fine, just limit the number of summons. Besides, if each summon takes a limb and renders them out of commission, then isn't it fair to say she can only have 3-4 summons anyway? In any case, this isn't a point that will be changed. As [@Lonewolf685] said, 3-4, no more than that. It's not up for discussion.

On to each summon having a weakness; again, that's fine, but you need to put those in your CS. As [@Lonewolf685] said yet again, it's the GM's job to make sure these powers aren't too OP for the setting they're playing in but if you make these weaknesses more apparent into her CS, then that makes it all the easier for all of us. I can allow defeated summons not appearing for several nights but understand that time skips will usually be a thing in this RP; as such, that would make this aspect almost unnecessary. Depending on how the story goes will determine how time flows but overall, I can accept this limitation. 

Onto her being rendered weak; there is reason why we put each of your characters into your teams.  I don't see how limiting the number of summons limits any creativity on her part because she still has one for each limb. I do see how she would be rendered immobile because of her magic, but also remember you have a partner, as well as the rest of the Magical Girls to help you. It's not like you're fighting alone here so I have to say I'm keeping firm on the notion for 3-4 summons. If she finds herself in a bad situation, call upon your partner or the other Magical Girls to help IC.

Something else I want to address that I'm not sure if you responded to or not, but we'd like her fear-reading ability to change. That's simply too problematic for us to manage if she can read every character's fear. Thus, I suggest you can change to something like pulling from a general and universal pool of fears. After all, her summons already kind of go off that theme anyway as they all fit with general fears most people have.

Overall, you can have the summons provided you make their weaknesses more clear in her CS, limit it to 3-4, and consider changing her fear-reading ability to one where it's universal pool of fears or something else that doesn't involve reading other character's fears. That's the compromise and the verdict we've given. Again, we never said we blatantly don't like your character. But you need to edit her to fit the appropriate suggestions we make as GMs to make sure she's balanced and fun to play as regarding other characters.
