>>1970805I did about a few months after she was created, around the same time I registered on Nico Nico Douga in mid 2008.
I'm not sure which was the video I first saw her in, but Triple Baka was the first song I listened to that had her singing in. I knew she wasn't a Vocaloid, but unlike Neru and Haku she had a voice, so I was really curious about her.
I became a fan after learning about her origins as an April Fools joke that was made into a true singer, and I started to listen to UTAU thanks to her.
