COWSEP.

Cowsep got into video games as a teenager and started playing League of Legends in December 2009.

He started streaming in his free time in 2014 and decided to attempt to attract viewers by wearing a cow costume. It paid off, as his channel grew so quickly that he was able to quit his teaching job in order to focus on full time streaming by 2015.

He is known for his Master Yi builds and sharing his thought processes with his chat.
