I'm think this one is CREA. I just capped the pics from the Limited TA Live Pamphlet DVD thing. It's the same one that's hanging around Ayu in the 'recording of rainbow'. (Sorry can't find my file of this to take any screencaps ><)
OR
It might be this one.. out of the 'My story' album booklet.
Ayu said Crea was the dog that looked to most like her, that's why she chose to compose under that alias. IMO the first dog looks more like her than the second, but i dunno >< sorry.
