Lol, the name Lyra brings HDM vibes in me.
I see Lyra being more likely to be a new character, rather than being Crys in a new outfit. As people have said before, Crys could be her mentor. I can certainly see it.
I see it too, but if Kusaka and Yamamoto have other things in mind. Well we just have to test our luck on the outcome. Also i don't really like HG/SS Gold's outfit. I liked his old style.
