Well...Gakupo is 24 and he sang about eggplants. The video was hilarious. I was laughing for hours after I saw it. Unfortunately there wasn't any translation...well...unless you understand Taiwanese XD
Huh, vocaloid ages all seem to be a little variable, do their products state anything official, or is this all just speculation based on their looks? I thought Kaito was 18. Still hilarious, of course.
