The tenth anniversary of Studio Trigger's founding was celebrated on the SiIvaGunner channel with a channel event. It was revealed in the video "The Bounty of Ryuko Matoi - The SiIvaGunner All-Star Summer Festival 2021".
Several rips uploaded on this day featured songs related to works produced by Studio Trigger or Gainax. These were planted throughout the day and did not halt the channel's regular uploading schedule. The event culminated with the release of the album STUDIO TRIGGER QUALITY MUSIC WORKS, announced through the video "DON'T LOSE YOUR ANNOUNCEMENT". In addition, the Ambiguous Fusion Collab (a fusion collab of "Ambiguous" by GARNiDELiA, the second OP to Kill la Kill) was released over 2 months later.
