What relation is Adelheid to Rugal?

Yes, it's a one response thread.

I haven't heard and I'm curious. Thanks.

I beleive Adelheid is Rugal's son. One of the guys in these forums (I forgot who) has a gif image of Adelheid and Rugal flashing behind him. I mean, most of his moved are the same as Rugals, as is the way he dresses. That gif image sealed my opinion on the topic. I could be wrong though.

Thanks. Who's that chick that's with him? His sister?

Yes, Rose is his sister.
