Yeah that's what I was on about with the notes. Been rewatching the episodes and since I haven't dug deep into the manga yet (need to do that at some point) I'd propose like I did on the notes to play her as close as possible as to how she is in the second anime. In which case while she has the most powerful ability at least concept wise, she's not been able to just up and save the day. And as to being broken, Yes it is. But is it any more broken when the cast has characters from Nasuverse and Touhou, and from the most recent conversation, It seems one of the worlds visited was Blazblue. They got city wipers and casuality breaking things in there. So if you want a limit on em, well make it storywise/plotwise as it has in the anime. After all you're sort of the main author if this story.
