TRUSTRICK was a Japanese J-pop and pop rock duo formed in April 2014 by Sayaka Kanda (神田沙也加) and Billy. Signed to Nippon Columbia, the unit debuted with "Eternity", released on June 25, 2014. Its name combined the opposing words TRUST and TRICK, reflecting the pairing of Kanda's vocals with Billy's songwriting.
The duo later became part of the anime song field through works including "FLYING FAFNIR", the opening theme for Juuou Mujin no Fafnir, and "Recall THE END", the ending theme for Danganronpa. TRUSTRICK entered a hiatus in 2016 and formally announced its disbandment on April 5, 2019.
