Jenny Matel arrives at East Oizumi Academy as an Italian foreign exchange student, immediately joining its cosplay club. She possesses blonde hair, blue eyes, a notably large bust, and occasional snaggletooth or cheek curl quirks. Her personality radiates high confidence and extroversion, often expressed through overtly playful behavior.

A core facet of Jenny is her Lolita complex, driving persistent sexual attraction toward Athena Imai, a prepubescent clubmate. This compels repeated attempts to engage Athena via suggestive remarks or actions like undressing her. These advances trigger intense protective reactions from Athena’s older sister, Maria Imai, who responds with fainting spells or physical interventions to separate them. Jenny’s excitement over Athena sometimes erupts in comedic nosebleeds.

Within the club, Jenny actively participates in cosplay events, frequently selecting elaborate animal-themed or furry costumes. Though enthusiastic about club objectives, her fixation on Athena and general exuberance often derails activities. Her unwavering confidence starkly contrasts with fellow members’ traits, particularly Chako Hasegawa’s clumsiness.

Jenny’s role remains static across original OVAs and related media, with no significant development, expanded background, or resolution to her storylines. She solely generates comedic conflict through her pursuit of Athena and chaotic club involvement. A subplot featuring a mysterious blue-haired woman excludes Jenny entirely.
