A Sphire came to Earth and fused with a lava pit and turned into Giralen. The kaiju made his way towards the Earth base of Super GUTS while most of the team was distracted by other Sphires. After Ultraman Dyna destroyed a portion of their squad, he came to Earth to fight Giralen as he was decimating the base's security forces. While Giralen's flames held off Dyna it didn't take long for the hero to go into Miracle Type. Dyna was easily outspeeding Giralen and he held the lava kaiju in the air he used the monster's own flames to blow him to pieces using the Revolium Wave. After Giralen's destruction, the Sphires left the solar system.
