a 346 Pro idol, Koshimizu Sachiko have her birthday on Nov 25, today. you might remember her from The iDOLM@STER: Cinderella Girls anime series, as one of the blue uniform trio.
The easiest way to say about her, is she is quite similar to Nico Nico ni, she show cuteness to fans but close one saw her sadistic side, and also want to be top idol. She believes to be the cutest, and don’t admit her mistakes with confidence. This apply to even her cards in-game, as she has Self-Proclaimed prefix and skill to buff its own and debuff opponent so she become the Cutest.
