Elucia de Lute Ima

Elucia de Lute Ima (エリュシア・デ・ルート・イーマ, Eryushia De Rūto Īma), more commonly referred to as Elsie (エルシィ, Erushī), is the deuteragonist of The World God Only Knows. She is a New Devil from New Hell and is an agent of the Runaway Spirit Squad, an organization of New Hell Devils whose purpose is to capture actively dangerous souls.

At the end of the story, Elsie later officially became part of Katsuragi's family and changed her name into Eri Katsuragi.

Personality
Elsie is an overly optimistic individual with a playful personality. Despite claiming to be over 300 years old, she has the mentality of an incompetent teenager, and is in many aspects conspicuously immature. Although earnest and hard-working, Elsie has become infamously inept at virtually everything save cooking and cleaning, but she only owes her skills during her post as a custodian.

Yet, with all the insults and derision Elsie receives from Keima, she usually does not dwell on them for very long and continues to make mistakes anyway. Though whether it is because of a strong will or her inability to comprehend the verbal abuse is unclear.

Furthermore, Elsie has the tendency to stay positive and persevere regardless of her flaws, demonstrating that she is at least the type of person who is determined to succeed while she still has chances.

Elsie is very loyal towards Keima and cares about his well being and opinion of her. She is often seen trying to help him and please him. Though she is not always useful on quests, she works hard in her own way. However, after being criticized by Keima, Elsie was shown to be extremely upset.

Elsie also possesses a comedic obsession with fire trucks as well as with the popular idol, Kanon. She was visibly shocked to see that Keima had no idea who she was. She calls Kanon by name with the suffix "-chan" and has called her "cute". Elsie even fashioned and bought the same ribbon as Kanon. Though Elsie is usually very respectful to Keima, she defended Kanon when he called her only a mere relic of a previous age and called her prettier than the girls of Keima video games that he adores.
