Elucia de Lute Ima (エリュシア・デ・ルート・イーマ, Eryushia De Ruuto Īma), also known as Elsie (エルシィ, Erushī), is the female deuteragonist in The World God Only Knows. She is a Devil from new Hell, and is over 300 years old (Even though her appearance suggests she's around 17 and her personality is yet only 10 to 12). She is an agent of the Runaway Spirit Retrieval Squad to capture escaped spirits. Her partner, or "buddy", is Keima Katsuragi, who is the protagonist of the series. She is currently pretending to be Keima's half-sister. She has an abnormal fondness towards fire trucks.

Elsie is a happy-go-lucky individual, in sharp contrast with Keima's cold, efficient, detached demeanour, and maintains an optimistic personality. Despite claiming to be 300 years old, she has the mentality of an incompetent teenager, which she resembles, and is in many aspects less mature than Keima. Although she is earnest and hard-working, she is infamously bad at virtually everything but cooking and cleaning, having been stuck on cleaning duty for hundreds of years; the only reason that she is now on the Runaway Spirit Squad is entirely because Hell is experiencing a personnel crisis and has every available hand recruited. As a result, she received little training, and constantly fails to provide proper support during conquests, although this could also be explained by her air headedness.
