interesting take on an earlier version of the SDM

I've read plenty of stories about Remilia taking Flandre as her sister and they're always interesting to ponder about, since those takes about their origin as sisters somewhat explain how Flandre is rather unique compared to Remilia despite both of them being vampires.

^ I assume there is nothing official on them prior to showing up in gensokyo? Its interesting to see origin stories about the sisters and the SDM crew. In my head cannon they are real sisters tho- there can be many reasons to explain why flan is so different to Remi.
