He is Leonidas's best friend. He bought a dvd of Hentai, but before watching it, Icecream Man had stopped it. Arthur.exe tried to get Leonidas, and Kaeru put himself up and said "gotta go through me". He also witnessed Andy being bullied, and wanted to put an end to it. So even though Kaeru is weird, he cares for people. He proved his kindness again in his dream against Arthur.exe. Arthur.exe said to him and Stanley Jones, that he would just take on of them. Kaeru looked at Stanley Jones, then back at Arthur.exe. He told him no deal.

He is also a producer and editor. He helped make a video with Mario & Benjamin Frankinstein.
