I believe they are because there is alot of WakaxAmmy going
around. If they aren't then that's just sad cause they should be.
And besides, during the trailer Kurow said he felt a vibe between
Chibiterasu and himself. Still, Capcom, make the two brothers! They
should be brothers! Oh and Kurow is nothing like his dad, but he is
cocky and graceful like Waka. However, he seems real focused in a
battle like Ammy. One last thing, in the blogs, it say that Kurow
is possibly Waka's son, but it doesn't say who his mother is?! I
believe that Ammy is his mother.
