Description
Josephina originates as the imaginary companion of 12-year-old Santi, manifested as a blue-green whale residing within the glass of water on his nightstand. Though invisible to others, she possesses tangible effects on the physical world, such as causing an earthquake when threatened.

She alters her physical dimensions at will, from as minuscule as a mouse to as colossal as a mountain, and demonstrates the capacity for flight, transporting Santi on dreamlike adventures that serve as a refuge from his insecurities and real-world challenges.

Her primary function involves providing emotional support and guidance to Santi as he navigates childhood difficulties. She acts as his confidante and moral compass, offering advice on family relationships, including his perception of his younger sister Rosa and his evolving understanding of his parents. She specifically challenges Santi's view of girls as "horrid" by reminding him his mother and grandmother were once girls who love him deeply.

She plays a crucial role in helping Santi process significant life events. This includes coping with the death of his beloved grandmother, where a dedicated episode explores their shared grief. She also assists him during his anxiety over receiving First Communion. In one instance, Santi accidentally swallows her with a glass of water, leading to a situation where he fears she might grow inside him; she ultimately escapes by becoming stuck to his belt.

Her presence proves instrumental in Santi's emotional development and transition towards adolescence. She supports his burgeoning first love interest in Celia, whose feelings appear reciprocated by the series' conclusion. This shift towards real-world relationships signifies the beginning of his decreasing dependence on Josephina as an emotional crutch.

Josephina's narrative arc culminates in a bittersweet departure. As Santi matures and gains self-assurance, he no longer requires her constant companionship. Her departure brings sadness, reflecting the end of his childhood reliance. However, it is suggested Rosa, Santi's younger sister who previously demonstrated occasional glimpses of perceiving Josephina, may become her new companion.
