Flandre looks kinda surprised or confused here. Is Rumia telling her that she's actually her sister, and not Remilia's?

We'll find out if this gets translated.
also, Transbump

I can't read kanji but from what I "can" read, it doesn't seem so. She seems to talk about her "power" or something.

Thanks for translating.

Now, i don't know for whom i should feel bad here.

For Rumia, because in almost any other work "manipulating darkness" is among the top class of powers, she still has that goddamn ofuda that she can't touch and has a 99% of chance that noone will ever speak of her again.
Or for Flandre, who has power but is not allowed to go anywhere and as said for Rumia there's a really little chance to see her again.

I want a game with them, causing an incident by covering all of gensokyo in darkness and making things explode for the lulz.

"They've been holding you back Flan! Look at what you're capable of!"

Pay respect to her, Flan
She is far more crazier than you!
