Ormi and Logos worked for Yevon under Maester Wen Kinoc to assure the failure of the Crimson Squad before joining up with Leblanc. When Leblanc poses as Yuna and organizes a concert in Luca, Rikku and Paine disrupt the show to retrieve their stolen Garment Grid. When Ormi and Logos cut Rikku and Paine's escape route, Yuna joins the battle. After losing the battle against the Gullwings, Ormi and Logos flee with Leblanc to their Chateau Leblanc hideout in Guadosalam.
Near Mt. Gagazet's summit, Ormi, Logos and Leblanc fight with the Gullwings for the sphere hidden in an abandoned Floating Ruins. On the way to the top, Ormi sends goons to halt Gullwings' progress but the Leblanc Syndicate is beaten by Boris, guardian spider of the Gagazet's "shrine".
Ormi and Logos join in the fiend hunt in the Mushroom Rock Road to get to the entrance of the Den of Woe and are surprised to see the Gullwings spying on them and flee. While escaping, they drop one of the Crimson Spheres needed to open the Den's gate.
- Ormi originally held the record of being the most recurring boss character in any Final Fantasy game, appearing in a battle a total of seven times in Final Fantasy X-2 until the introduction of Caius Ballad from Final Fantasy XIII-2 with a grand total of nine battles.
- Ormi is blamed by Logos when Logos is caught red-handed by YRP, when they are watching a sphere in Logos's room that shows his "other" interest during the game.
