In Episode 40, Glitter Sunny uses a powered-up version of the attack, named Sparkle Fire Inferno, known in Japan as Sunny Fire Burning (サニーファイヤーバーニング Sanī Faiā Bāningu).
Glitter Sunny first charges up her Glitter Pact with fighting spirit, making it glow and granting her power. When enough fighting spirit has been collected, the Glitter Pact explodes in fire to form a fireball in the sky. Glitter Sunny then does a run, jumps into the air, spins and blasts the fireball at the enemy in a volleyball spike.
Sparkle Fire Inferno
Glitter Sunny positions herself in the air surrounded by fire as she takes masculine stance. Then Sunny's face is shown in a brief scene as fire flew past her and a big fireball appears as Sunny draws closer to it. She then shouts and shoves the inferno at the enemy.

- In Sparkle Fire Inferno, the fireball's effect is many times stronger than Sparkle Fire.
- It is shown that if Sunny is already in the air, she doesn't need to do the run and jump.
- It is also shown that she can snap her fingers to create a mini version of this attack any time.
