OVA
Description
Nagisa Saitō, a human with indigo hair, gray eyes, and tan skin, dons the Lemon Beach House uniform while balancing part-time work with high school studies. Her job choice stems from a passion for the ocean, which fuels her surfing hobby alongside biking, jump rope, and a fondness for magical girl or tokusatsu shows.

Driven by an intense fear of Squid Girl—whom she deems a legitimate threat to humanity—Nagisa clashes with coworkers who dismiss her concerns, leading her to suspect their nonchalance results from brainwashing. Squid Girl amplifies this tension by theatrically exaggerating her powers to unsettle Nagisa further. Eventually, Nagisa redirects her wariness toward Chizuru Aizawa after witnessing her formidable competence.

To counter Squid Girl’s provocations, Nagisa experiments with a boyish disguise, slicking her hair back to attract female patrons, but abandons the ruse upon accepting the need to confront Squid Girl’s antics directly. She also feigns indifference to avoid provoking attention, though her fear betrays her during physical interactions, like refusing handshakes.

Nagisa’s older sister, Aiko Saitō, a teacher introduced earlier in the manga, contrasts with friends Koike and Yamada, who debut in later chapters during their inaugural Lemon visit. Despite finding coworkers Eiko and Chizuru eccentric for normalizing Squid Girl, Nagisa maintains professional camaraderie.

Though her dread of Squid Girl persists, flashes of resolve emerge—such as retaliating after an unwanted hug—showcasing her adaptability. Her expressive nature is highlighted through tactical disguises and shifting strategies, underscoring a blend of caution and determination.

Her documented appearances span Season 1 Episode 3 and Season 2 of the anime, alongside manga chapters including her friends’ introduction in Chapter 364.
