I became a fan in 2008. So...(If I had been a fan around early 2000, I'd probably start with Mikitty---but I do like her even when she already graduated when I came to know MM) Koharu [oshi]-----> 2010 Takahashi --> 2011 when 9th and 10th gen joined, I was juggling between Riho and Maachan in my like list--->2012 Tanaka-->when Sakura joined, I started to like her but not oshi status yet. It was the start of 2013 that she solidify that status in me.
so.... Koharu--->Sakura really... lol
