Little Bel is the younger trainee counterpart of the shipgirl Belfast, learning directly under Belfast's mentorship to become a Royal Navy maid. Her training focuses on proper etiquette and service fundamentals, starting with basics like tea preparation and hospitality. During a session where Belfast hosts guests Javelin, Ayanami, Laffey, and Z23, Little Bel practices serving them, entertaining the group, and assisting with cleanup. This emphasizes hands-on experience with peers to develop competence beyond basic cleaning or entertainment. As part of her protocol education, she formally addresses those she serves as "Goshujin-sama".
