An old clip from a collab in 2018, where the 3 talk about their beginnings.
The first bit I included just for fun. Later it gets to the important parts.
The source of this clip (Streamed 12/17/18):    • みとうヤッタゼでおしゃべる  

Tsukino Mito:    / @tsukinomito  
Kenmochi Touya:    / @kenmochitoya  
Elu:    / @elu  

Some notes:
•This was streamed on a platform called REALITY. Due to some complications, Elu wasn't in 3D.
•The song Mito sings, "What can you do in 45 seconds?" was a popular song to dance to back in the days.
•I'll always write dates as Month/Day/Year, sorry if it's confusing. (I just realized recently that the rest of the world doesn't do that...)

I wanted to clip this after watching this year's Mito's 100 Horror Stories Stream:
   • 【#帰れない百物語】100個怖い話するまで帰れない2020【月ノ美兎/にじ...  
It's not directly related, but...after watching the stream, I wanted to appreciate these Vtubers for being who they are now.
