Hi, thanks for checking in with us! Hopefully these answers are helpful lol.
1) That's more than enough for BD! So long as you have enough of a read on their personality to play it consistently in RP and build an AU around it, that's totally fine. We have a few folks playing from ongoing works in game so you'll be in good company!
2) We don't necessarily have a Hard And Fast Rule for this sort of thing, just to allow ourselves some flexibility but based on your comment here, while having assassination or murder in her backstory would not fit in with BD tonally, something like her being a reformed former delinquent might be a good fit! I'm not familiar enough with Gachiakuta to suggest something more specific but hopefully that example should be good as a general ballpark to aim for.
3) No worries at all! Basically, because we do not accept duplicate characters and our overall franchise cap is relatively low, BD does not accept characters from pre-existing player-made AUs that are unconnected to the game - CRAUs, roleswaps, that sort of thing. I hope that clears things up!
