Sweetie denotes both a formidable fairy weapon and the primary alias of Vera Miyako. This individual commands the Sweetie weapon, manifesting as massive floating gauntlets that unleash devastating punches. Vera possesses a petite frame, fair skin, short blonde hair often covering one eye, and favors practical, dark clothing.

Her origins lie within the clandestine organization Dorothea. Taken as a child, Vera endured intensive conditioning and combat training alongside Marlya Noel, forging a sisterly bond. She developed fierce, protective loyalty towards Marlya, prioritizing her safety above all else, including Dorothea's directives or personal cost. This bond dictated her path.

Initially presented as a ruthless enforcer for Dorothea, Vera executed missions with cold efficiency using Sweetie's destructive power. Yet her core motivation remained protecting Marlya. When Dorothea's plans directly endangered Marlya by targeting her fairy, Vera chose betrayal. She sabotaged Dorothea's operations to shield Marlya, marking a pivotal turn.

Following this betrayal, Vera operated independently, driven solely by ensuring Marlya's survival and well-being. This involved covertly observing Marlya and intervening against threats, whether Dorothea remnants or others, navigating conflicts involving fellow Fairy Soldiers and government agencies.

As external threats escalated, Vera's protective nature intensified. She actively sought to eliminate dangers to Marlya, sometimes employing aggressive tactics. This culminated in a confrontation where Vera sacrificed herself. Pushing the Sweetie fairy weapon beyond all limits in a final, overwhelming attack against a significant threat to Marlya, the exertion proved fatal, resulting in her death.
