Peruru is a supporting character within the "Super-Dimension Legend Rall" storyline of the Cream Lemon anthology. Trapped in a dragon form by the antagonist Ramorue's magical transformation, he serves as companion and close ally to the warrior Caron. He assists her mission to rescue a kidnapped princess and stop Ramorue's conquest of Earth and planet Rall; this dragon state represents a curse imposed upon him. His background includes eventual liberation from this curse when the binding spell breaks, allowing his restoration to his original human form. This signifies the resolution of his magical imprisonment. In the 1993 Cream Lemon anthology film adaptation, Peruru's role expands beyond the original OVA depiction. He transitions from primarily being Caron's companion to actively participating as her sidekick in the conflict against Ramorue. A key development is Peruru receiving his own sword, reflecting his elevated status and direct combat involvement alongside Caron, contrasting with his original, less combat-oriented assistance. Peruru appears exclusively within the "Rall" segments of Cream Lemon media. He is absent from other anthology storylines like "Ami" or "Escalation." His character development, including the curse and its reversal, remains specific to the Rall narrative across its OVA and film iterations.
