OVA
Description
Emi Kojima is the human alias of Septem, a being originating from the magical realm of Evergreen. Septem assumes this identity upon transferring to the school attended by Chihaya Hiiragi, using the guise to maintain cover during her time on Earth. Her journey to Earth is undertaken alongside Bergamot, Chihaya's father, with the shared goal of protecting Chihaya from adversaries named Fennel and Calendula. Bergamot had enlisted Septem's help after stealing hazardous seeds from Evergreen, prioritizing the safety of his daughter.

In terms of personality, Septem is defined by an unrequited love for Bergamot. This feeling is complicated by the fact that Bergamot fixates on Septem due to her striking resemblance to his late wife, Emi Hiiragi, who is Chihaya's mother. This dynamic creates a layer of personal tragedy and unfulfilled longing that motivates her actions.

Her role within the story varies significantly depending on the adaptation. In the non-hentai television anime, which aligns with the content of the Magical Kanan Summer Special, Septem is depicted heroically. She stands alongside Bergamot as an ally in the fight against Fennel and Calendula, consistently aiding in the protection of Chihaya and the retrieval of the stolen seeds. This portrayal contrasts sharply with the original hentai OVA, where she is cast as a villainess serving Fennel and Calendula directly against Chihaya, even going so far as to claim she is Chihaya's biological mother.

Key relationships center on Bergamot and the shadow of his late wife. Septem's resemblance to Emi Hiiragi is the primary reason for Bergamot's interest in her, making her a figure caught between her own feelings and being an object of another's grief. Her relationship with Chihaya is therefore defined by this connection to her parents and the mission to protect her, rather than any maternal bond in the heroic version of the story.

Regarding character development, the available information suggests that Septem features across multiple pieces of media, including the four-episode hentai OVA series from 2000 to 2001, the two-episode Palpitating Summer Camp OVA from 2002 to 2003, and the non-hentai television anime Magical Canan from 2005. The Palpitating Summer Camp OVAs include her character without significant development. The most prominent description of her physical appearance notes that Septem has violet ankle-length hair, garnet eyes, and is frequently depicted wearing a tiara. Regarding notable abilities, while Septem is described as a being from Evergreen's magical realm, the specifics of her magical powers or combat skills are not detailed in the search results.
