I can hear it too a little bit
damn i missed yuukarin Sayu said on the latest Usa-chan peace radio that Sakura is very good at mimicking other members singing voice. She's done Dawa's part in Samui ne~, and she can imitate Sayu and Fukuhime's voice too. Sayu thinks she can probably copy every single Hello!Project member's voice
Sakura actually mentioned Miki by name as someone she aspires to be and has done a lot of research on her voice watching dvds and such so any similarities with Mikitty is definitely not a coincidence. I'm not even sure that we've heard her own style of singing at this point, it's really an exciting time to be a Momusu fan
