The character "Kagato (little girl form)" originates from the *Tenchi Muyo! Ryo-Ohki: Final Confrontations* OVA. This entity constitutes the female half of Kagato Araki, separated due to his intense hatred of women. Antagonist Dr. Clay recovered these cells and implanted them into Noike Kamiki Jurai upon identifying her as a suitable spy. He branded the cells with his logo to prevent full assimilation and maintain control over this aspect of Kagato.

During the episode's events, an analysis detected these anomalous cells within Noike. The Choushin goddess Tokimi intervened, extracting the cells from Noike's body. This extraction caused the female Kagato cells to physically manifest as a distinct, child-like entity. Scientific genius Washu Hakubi confirmed the cells' origin and removed Dr. Clay's seal, enabling complete separation and emergence.

Immediately after liberation, this Kagato form references a prior invitation for Tenchi Masaki to have lunch aboard Noike's ship, Kyoko. This remark provokes a confrontation between Ayeka and Ryoko, demonstrating her provocative influence despite her brief presence. The character does not appear or develop in other *Tenchi Muyo!* media, including later OVAs, spin-offs, or alternate continuities like *Tenchi Universe* or *GXP*.
