The Legend of Luo Xiaohei (ç½Âå°Âé»ÂæÂÂè®°) is a flash animation and webtoon developed by Chinese artist MTJJ (real name Zhang Ping ç« å¹³). It derives from an animated series that was mainly broadcast online in March 2011. The franchise has also been extended to become a social media sticker series on WeChat. As of July 18, 2021, 40 episodes of "The Legend of Luo Xiaohei" are available alongside 3 extra videos, "Exam Day", "Shâ¦", and "Goodnight Meow". A feature-length prequel film named The Legend of Hei was released in Chinese and Japanese theaters in September, 2019. A second feature-length film The Legend of Hei II was released in 2025.
The series was adapted into a graphic novel in 2015, published by Beijing United Publishing. It has also been turned into a mobile game titled "Luo Xiaohei's Battle Demon Book" (ç½Âå°Âé»ÂæÂÂè®°å¦Âçµ簿) by Beijing Manya Entertainment Culture Media Co.
The story begins on a rainy night when Luo Xiao Hei, a cat spirit, is badly injured after stealing Laojun's wish-granting pearl artifact, the Pearl of Heaven. As a result, he is transformed from his humanoid form to become his original black kitten form. He is then saved by a young girl named Luo Xiaobai, who takes him home. Luo Xiaobai and Luo Xiao Hei become good friends and their adventure begins. They live in a world where people, spirits, and gods coexist.
The first season revolves around Luo Xiao Hei and Luo Xiaobai visiting her grandfather in the countryside for the summer while her parents go on vacation. Here, she's introduced to the wider spirit world through her cousin and brother figure A'gen, who is secretly an ice-affiliated elfin. They spend much of the first half evading Laojun's attendant, Diting, and several third party groups who want to steal the pearl for their own purposes. Once Xiao Hei is able to restore his spirit energy and turn back into his Elfin form, he intended to leave Xiaobai and A'gen, but instructions from his master Wuxian allow him to stay with them a little longer.
Those instructions form the plot of the second season, where Xiao Hei is supposed to befriend a few humans and enter the world of the elfin-developed video game All Living Things in order to complete a particular vigorous quest. The quest, as it is revealed in the latter half of the season, is actually a test for Xiaohei to prepare him for his prospective job as an Executor (a type of roaming enforcer for mainstream elfin society) and graduate from his apprenticeship. Unfortunately, he is severely underleveled and has not obtained any of the items or clear conditions that he needed before nearly getting locked out of the quest for good.
The Legend of Hei is an animated film prequel to the animated series The Legend of Luo Xiaohei released in summer 2019. The movie details various events in the life of Luo Xiaohei before the show.
