Lu9 was invited to SiIvaGunner in early 2016 (when it was still the GiIvaSunner channel) after Chaze the Chat heard some of his fan rips on SoundCloud.
Due to the quality of his submissions he was promoted to Quality of Control, and then later promoted to backroom. He was later demoted back to QoC.
In December 2019, he was removed from the team. He decided not to return to the channel.
He is mostly notable for creating the Cave Story rips that feature the music from VeggieTales.
His last rip was "Pizzeria - LEGO Island 2: The Brickster's Revenge" and was uploaded on November 8, 2019.
During his time as a contributor Lu9 made 208 rips for the channel.
