"Angel of the Fire Festival" (Japanese: 火祭りの天使 Hi matsuri no tenshi) is a fictional piece of music mentioned in Yuri!!! on Ice Side Story - Welcome to the Madness. This piece was choreographed by Lilia Baranovskaya as Yuri Plisetsky's original exhibition skate. Yuri skated to this piece for every event, up to the Barcelona GPF.
After the Barcelona GPF, Yuri, failing to beat Yuuri's free skate score, decides against performing Angel of the Fire Festival for his exhibition skate. He believes that because the piece is related to his free skate, it would remind the audience of it, which frustrates him. Instead, Yuri instead chooses to use Welcome to The Madness as his Barcelona GPF exhibition skate.
