In order of how much I like them:
1. Minegishi Minami- Miichan's coming REALLY close to Lovetan levels of fandom for me. Miichan is DEFINITELY one of my oshi; she's hilarious, sweet, cute and just. I can't find any flaws in her; she's amazing.
2. Miyazawa Sae- my first Oshi; even though she's dropped down my list a lot I still think she's hilarious.
3. Umeda Ayaka- I don't know her too well just yet, but she seems really fun. I NEED to look up more about her.
4. Oshima Yuko- she's a fun, great front girl.
5. Kikuchi Ayaka- ... I may have just voted for her because I adore Watarirouka
She seems nice, though.
