There's no other way to say this, but - I'm idol trash. Anything with idols, I love it. But, particularly, I am a fan of these two franchises:
Are you RE@DY? I love The iDOLM@STER series. My first encounter with the series was with the excellent anime, which you can watch for free (seriously, legitimately) at Crunchyroll (at least in the US).
After getting into the anime and falling in love with the characters and the music, I bought the iDOLM@STER Shiny Festa games for iOS, still the only iDOLM@STER games which have had an official release in the West. After thoroughly enjoying those, I also ended up importing iDOLM@STER 2 and iDOLM@STER: OFA, and watching Cinderella Girls.
I have thoroughly enjoyed the iDOLM@STER universe, its characters, and its music. I find it to be the deepest and most interesting idol series.
µ's music start! Besides iDOLM@STER, my other favorite idol series is Love Live! The energy, the enthusiasm, the cuteness... I love everything about this series. Especially a certain adorable, cat-obsessed, bucket of energy.
I loved the anime, although the end of the first season felt like a punch in the gut. The characters may be a little stereotypical compared to other series, but the overall series left a warm feeling with me that keeps me in love with the series and the girls.
I'm hopelessly addicted to the LLSIF game (I play on the English server as trdaisuke), I imported 2 (of the 3) ridiculously easy Vita games, and I run a Rin-focused Tumblr page.
I made an online calculator designed to help LLSIF players keep track of the pace of their event points during special events.
