Amidst Raimon's training for Senbayama[1], Aki suggested Domon trying to teach the Tri-Pegasus he, Ichinose, and Nishigaki used in the past to the Raimon members and thus increasing their chances at scoring against Senbayama, but Domon had difficulty expressing how to perform it and exemplified instead by drawing it on the ground.
As a gift of his gratitude to Endou, Ichinose decided to perform Tri-Pegasus with him and Domon[2], training arduously for two days. However, all of their attempts were unsuccessful until Aki acted as a landmark that all three had to cross past without coming in contact with her, to which Ichinose remarked she had done the same in the past.
As the American quartet meets at last[3], Ichinose mentioned how Endou managed to make Tri-Pegasus a reality again, much to Nishigaki's surprise.
In the match between Raimon and Kidokawa Seishuu[4], Ichinose, Endou, and Domon used it, quickly getting past Nanzan and scoring Raimon's first goal, surprising Nishigaki in the process who had been left in disbelief. Ichinose, Endou, and Domon tried using it again to score Raimon's second goal, but were stopped by Nishigaki's Spinning Cut, to which Nishigaki remarked the pegasus' wings had been clipped. Ichinose, Endou, and Domon would later use it again to the request of Gouenji, breaking past Nishigaki's Spinning Cut and evolving Tri-Pegasus into The Phoenix, breaking through the Mukata triplets combined defense and quickly getting past Nanzan, scoring Raimon's third and winning goal.

Usage[]
The user in the center dribbles with the ball while the two others run beside them. All three users run in a line each at a time to form a triangle, with the user in the center leaving the ball behind. The trail the users left behind becomes lit up in blue fire, sending the ball high into the air. A blue fire-covered pegasus appears below the aura-covered ball and the three users then jump on top of the ball one at a time, sending it towards the goal.
