Yuka Ōzenji appears in the 1992 Original Video Animation adaptation of Babel II. She is a young girl with purple hair and blue eyes. Initially presented as a member of the antagonistic organization Psychic Labora, she secretly operates as a spy against them. Her mission involves infiltrating the group to gather intelligence and ultimately aid in its defeat, forcing her to navigate complex loyalties while maintaining her cover.

She possesses notable combat skills, including proficiency in martial arts, and wields telekinetic abilities, classifying her as one of the narrative's psychics. This expertise enables her direct engagement in battles against adversaries, extending her role beyond reconnaissance to active combat against supernatural forces.

Her narrative significance grows through interactions with the protagonist Koichi Kamiya (Babel II), functioning as his love interest. This relationship faces complications; she exhibits moments of possessiveness or jealousy concerning other women connected to Koichi, occasionally attempting to undermine perceived rivals. Despite these tensions, she acts to shield Koichi from danger.

Her personality aligns with Enneagram Type 2w1, showing traits centered on supporting others. A recurring motivation is protecting allies and ensuring their well-being, often prioritizing their needs. However, criticism impacts her negatively, triggering a need for external validation. Under relational stress, her supportive disposition can shift toward manipulative or controlling behaviors, particularly when fearing loss of connection. She consistently demonstrates loyalty by defending allies against threats.

Her character develops through sustained conflict against Psychic Labora and its leadership. This journey requires balancing covert operations with overt combat while adapting to escalating threats and managing concealed objectives. Her contributions prove instrumental during pivotal confrontations affecting the story's outcome.
