Vanessa appears in the OAV series "The Dark Chapel" as an adult female with purple hair extending to her chest and brown eyes. She resides within a chapel under a father figure's authority, where nuns are compelled into exploitative agreements. These pacts transform them into subservient beings focused solely on satisfying the father's desires, explicitly as "ass slaves." The narrative examines coercion and the violation of sacred vows, with Vanessa epitomizing this oppressive dynamic within the chapel's structure.
