Ilulu

Ilulu is a female dragon who belongs to the Chaos Dragons Faction. 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. Underneath she wears a black string thong with a matching bra. She has a generous bust and even in her human form, she has dragon-like arms. Like Lucoa and Tohru, her horns are visible in human form. Her dragon form is yet to be revealed, for her transformation, Ilulu is covered in a mass of flames in a vaguely bestial shape, only to be interrupted by Tohru with her attack. When she first appeared, Ilulu was a psychotic, war-mongering force with a firm hatred for humanity. She initially was disgusted by the idea that Tohru could coexist with a lowly human, which led her to believe that Kobayashi must've been smitten by her. Her opinion on humanity was so strong, that she was shocked that Kobayashi would risk her life to save her so much so, that she was convinced that she was a trickster. 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. She doesn't feel any shame when naked in front of others. Hence when she invited Taketo to bathe with her at Kobayashi's apartment.
