“Ares” is a response to Youtuber and rapper Quadeca’s song “Insecure”. KSI and Quadeca’s beef started when KSI went on the What’s Good Podcast and called out various Youtube rappers. When co-host Miniminter brought up Quadeca and said he personally liked him and his music, KSI was quick to disagree, saying:

Quadeca, his last track was dead…
I feel like Quadeca thinks he’s sicker than he actually is.

These comments infuriated Quadeca and, in a response video, he said that he was going to make a diss track towards KSI to prove him wrong. Three days later, Quadeca dropped “Insecure.” In KSI’s reaction video, he claimed that the song was good and that he would bite and write a response. Hence, “Ares” was released.
