ilulu (maidragon)
イルル イルル(小林さんちのメイドラゴン) 이루루 iruru ilulu
A Chaos faction dragon from Kobayashi-san Chi no Maidragon that wanted to destroy Tokyo and was defeated by Tohru with the assistance of Elma. Was befriended by Kobayashi, lives with her like Tohru and Kanna Kamui and seems to be attracted to her just like Tohru.
Noted for her huge breasts (often upsized to gigantic in fanart), particularly on her petite frame, stemming from her incomplete mastery of assuming a human form.
Previously an manga-exclusive character, she later made her anime debut on the 2nd season of Maidragon in 2021.
