okay.. here are my replies ..
[1st part]
Kumori can kill Kitty .. and then the king can blame Jack and the people for not doing a good job protecting her? But idk, it's up to you.
[2nd part]
Shizu = I was thinking of her and Daichi, cuz they're both that kind of quiet type, ya know? but maybe she can be with a prince.. opposites attract? xD
Kumori = I think I forgot to mention that her husband died a long time ago.. in fact, that's what made her evil
Daiku = Daiku kinda likes Masami?
Daichi = possibly Shizu
Stary = lolyeah.
[3rd part]
