Electone is an android replica of Drum physically integrated into the wall of Ramunes IV's private quarters. She serves as his assistant and lover, maintaining unwavering loyalty throughout their history. Her core conflict stems from jealousy toward the holy virgin Cacao, who attracts Ramunes IV's unwanted advances; this drives Electone to violently attack Cacao under Ramunes' orders.

When Ramunes IV abandons her to pursue control of the destructive mecha Dark Knight, Electone retaliates against those challenging his legitimacy. She kills Don Vodka for revealing Ramunes IV is an impostor—a childhood placeholder leader until the true Ramunes could be found. Electone subsequently battles the holy virgins Parfait and Cacao but is defeated.

Following the Giga Genos spacecraft crash, Electone locates the dying impostor Ramunes IV within the Dark Knight. A flashback reveals her long-term emotional connection: she comforted him as a meek, reluctant child forced into leadership and later became his romantic partner. As he dies, he expresses disbelief that his identity was fabricated despite dedicating his life to the role. Electone reactivates the Dark Knight, unleashing planetary destruction, but is killed when Cacao and Parfait breach the mecha with aid from Ramunes' disillusioned followers.

Her narrative arc concludes rooted in devotion to his imposed identity. Electone appears exclusively in the "VS Knight Ramune & 40 Fresh" OVA.
