Voice him however you see fit!

"In a now deleted tweet by VIVINOS, it was mentioned that Till was the most sensitive and timid among all the participants. This corroborates his depiction in Round 2, where he is shown to be incredibly docile, especially in the presence of Mizi. Despite this, it should be noted that he also has a vicious streak, which was particularly evident in the aforementioned second round where he sang over his opponent in order to win.

Apart from this, Till is also noted to be an exceptional artist. He tends to get lost in the matter and frequently sketches." - Alien Stage WIKI

Mizi is pronounced (MEE-ZEE) or (MEE-JEE)
