I love the cute ponytail she went for, I miss her wearing them because she always looks adorable when using that simple, neat style

of course, she can pull off (almost) any hair style.
a bit surprised they gave her the SF top with sleeves

she's got sexy arms, why cover it up?
and this goes back to the whole why did they alter her costumes (DEF. DIVA one and IN MY LIFE one) to cover her arms? quite strange. either she DOES have an arm injury (needle shot does sound highly possible, I agree) or they just felt like altering it.
as for both DEF DIVA. and IN MY LIFE performances, they were AWESOME! both filled with energy, and the IN MY LIFE performance was really cute. Aya messed up the dance, but that's forgivable of course and she was still spectacular!
