Elise is the manifestation of Vita Sexualis, Mori's ability. As such, Mori's moods and desires largely affect Elise's nature as a "human", which becomes particularly evident when observing her past nature to her current. Furthermore, given Mori's "preferences", Elise does not age past the appearance of a young girl. When Mori activates her powers, Elise can fly at high speeds. She summons a giant syringe, harkening to Mori's background as a military and underground surgeon, and fights with superhuman strength. When defeated, Elise does not "die", she disappears. Mori can resummon her, however, it's unknown if there's a specific amount of time he must wait before he can do so.
Member of Port Mafia, a young girl usually seen with Ougai Mori.
