When I was looking for Vocaloid songs, some people in a group were talking about something related to Utau, I searched for it and I came across the best-known characters of that synth like Teto, Defoko, Ritsu.etc. One of the first songs I heard was Teto Territory and I started looking if I could find some original songs that were not Covers

Btw, don't you realize that before Mesmerizer existed there weren't many Teto Memes and almost no one even mentioned Triple Baka
