I have discoved what last happend to Yua be for she gone missing!

Yua disappeared after Ganer told her to run then Ganer battled the demon called Aruhameru in Gate when Ryu was a little boy. Ganer was captured after the battle because he lost. Then Yua was never too be seen again.

I diden't know...

I didn't know that. When they said that Patty knew all about the dragon, I thought that she was going to end up being Yua.

No patty isn't ryu's little sister because then she would have to have the light blue hair but she has a kinda blackish dark blue.

she could of dyed it:P

But her name is Patty in Yua or what ever her name is and i don't think they would have hair dye back then...

Patty is Yua!!! I thought you knew that

yes, I think patty was yue.

Patty was Yua you never think Ryu's little sister would be a master thief!

and also close to the end of the game they say a person from the light dragon clan must be killed to open infinity. and some of the only light light dragons are ryu's mom, ryu, and patty. so there you go she is his sis. because there both dragons of the light dragon clan like there mother.

mabey ryu's sister got killed by a monster...

Ryu's sister can't be patty in less she changed he name or something but i doubt she did!

mabey a beaky killed her...

A Beak probley not she probley grew for 10 years like RYu did.

I wonder what she looks like...
