Of the three, only Shimakaze's gonna appear in the anime iirc.
There are many girls in the iDOLM@STER series as well and so far I've done a decent job remembering their names... not their family names though.
But do watch it. I mean, just look at my new set. It's Haruna. HARUNA. HA-RU-NA.
I can assure you KimiUso's good. I really enjoy it, and that's why I'm still watching it despite the flags. But I don't want to spoil it for kamisama. That'd be blasphemy!
