Video, best?

the main and best Vocaloid

Nonsense. There are no "main" Vocaloids, there are only "first" ones, but even then, she doesn't fit the bill (Meiko and Kaito appeared earlier). She is just the most popular of them, which is why she is used first. I won't even talk about the voice; until recently, it was inferior to many other Vocaloids in terms of quality.

It was Amko who got me into this, yes! :3

Judging by the text of the post, it looks more like a report from "NTV," which is quite absurd, to put it mildly.
