By the way Shadow, I just realized I goofed slightly; Kyuui, as part of maintaining the grapple, needs to make a grapple check as a standard action each round.  Success means she can choose to automatically damage him with a natural weapon (or an unarmed strike, or a light or one-handed weapon), but failure means she loses the grapple.  She does get a +5 bonus to maintain it, though, and if I use your attack rolls as grapple checks instead, you've passed each time.
