Ilulu is a antagonist turned protagonist from the manga series Miss Kobayashi's Dragon Maid. Originally, she came to Kobayashi's world to destroy Tohru and then tries to drive Kobayashi away from Tohru. After a change of heart, she begins to live with Kobayashi as her third dragon resident.
Ilulu appears in her human form as a woman of small stature wearing a black cloak with fur. She has a generous bust and even in her human form she has dragon-like arms.
While originally somewhat chaotic and mischievous and hating humanity, Ilulu suffered a change of heart after seeing Kobayashi trying to protect her, This lead her to change her views towards humans, Once she redeems herself, Ilulu had some difficulties adjusting to human society, despite being roughly the same age as Tohru.
As such, Kobayashi often tasks Tohru with babysitting Ilulu. She also was determined to find her purpose in life, even though her initial conclusion was too lewd to put into serious consideration. Despite being thousands of years old, she behaves like a child similarly to Kanna, even though there are a few obvious differences.
