Description
Thirteen-year-old Osaka native Kamome Sengakuji ("sea gull") lives with her mother and stepfather after her biological father's passing, leading to financial strain that fuels her constant pursuit of money. She readily monetizes personal details like hobbies and measurements for classmates. Temporarily staying in Akihabara with her grandfather, former Rosenkreuz member Shimabukurou Sengakuji, she frequently bristles at his lewd behavior.

Physically, Kamome possesses long blonde hair featuring curled sides and two front fringes, complemented by blue eyes and a signature pink headband. Her typical outfit is a green Akihabara school uniform, white socks, and green shoes. Casual wear, seen in the OVA, consists of a teal denim dress and white flats sans headband. She actively enhances her bust size using padded or inflatable bras, sparking rivalry with peers.

Her electronic companion, the Pata-Pi Billiken, acts as a futuristic piggy bank and calculator, mirroring her monetary obsession. Billiken transforms into the combat Diva Amphitrite, powered by neutrinos. Kamome holds deep knowledge of Pata-Pi mechanics and the "pure soul" Anima Mundi concept, gained from her grandfather's Rosenkreuz insights.

Kamome becomes the Cyber Team's fourth member when Billiken awakens as Amphitrite during a clash with Jun's avatar Cerberus; this occurs as she declares herself an Anima Mundi to protect friends. Amphitrite wields a laser chainsaw and defeats Cerberus in their first battle. Kamome aids the team against threats like the Sibyl Team throughout the series. Later, Amphitrite is captured by Crane alongside other Divas and returned under his control for the finale.

Her OVA appearance shows character development through achieving Astral Fusion with Amphitrite, physically merging for enhanced agility. This fused state features a green-and-yellow armored suit and laser cannon for versatile combat. While absent from the main series, this form appears in the film's climax within the Primum Mobile space fortress. By the anime's end, Crane returns Billiken, reuniting them, but Kamome is devastated by the loss of her accumulated coins before returning to Osaka. Her personality blends a calculative nature with underlying loyalty, demonstrated through her efforts aiding the Cyber Team despite initial snobbery over their lack of Diva knowledge.
