Angelica crashes on Planet Sharaku during its 200th-anniversary celebration, afflicted by complete amnesia that erases all memory except her name. Kanipan discovers her and aids her recovery, uncovering Sharaku's imminent destruction during the process. Angelica's pendant device proves critical for activating advanced capabilities in Kanipan's robot Kid, enabling instant part transfers and transformations to combat threats.

Fragments of her past resurface, revealing her link to Dr. Taishi—Sharaku's creator—and vital knowledge about the planetary crisis. Her background ties directly to the Planetary Management Committee, from whom she escaped prior to the crash. A romantic bond forms between Angelica and Kanipan, contrasting Milk's unrequited feelings. Angelica joins the final confrontation to save Sharaku.

Post-victory, she marries Kanipan in a joint ceremony alongside Nuts and Kirsch's wedding, surprising him when she administers vows and kisses him. After Kanipan earns the TAISHI-Level license and departs with Kid, Angelica stows away on their ship alongside Milk, Igor, and Ravioli, leaving Planet Sharaku behind.
