Dioluna is a Wulgaru general serving as a major antagonist during the Earth conflict following the television series. As a high-ranking commander, Dioluna commands Wulgaru forces against Team Rabbit and their AHSMB units when the threat reaches Earth. The battle against Dioluna becomes a pivotal confrontation for Team Rabbit, demanding their combined efforts and full activation of their units' capabilities.

Within this engagement, Rose Three awakens through Tamaki Irie's piloting, unlocking its latent potential. In this state, Rose Three purges its upper armor to deploy high-powered beam emitters and generates a concentrated energy ball using its wing-like side armor. This energy ball possesses sufficient destructive force to defeat Dioluna, but Rose Three lacks the precision to aim it effectively alone. It must coordinate with Gold Four's targeting system to deliver the decisive strike. Black Six also assists in setting up the final attack. Dioluna's defeat by the combined strategy of Rose Three and Gold Four marks a critical victory for Team Rabbit against the Wulgaru forces on Earth.
