# Beast Complex

Beast Complex (stylized in all caps) is a Japanese manga series written and illustrated by Paru Itagaki. It is a compilation of short stories set in the same world as the series Beastars; its original run served as a predecessor for Beastars, and some of Beast Complex’s stories expand on characters from Beastars. The stories take place in a modern world occupied by anthropomorphized animals of various species. The animals are divided into carnivores and herbivores, and eating meat is illegal since it can only be sourced from anthropomorphic animals. Carnivores and herbivores often come into conflict due to the former's craving for meat.
It was first serialized in Weekly Shōnen Champion from March 2016 to March 2019. In 2021, the series resumed serialization.

## Development

While studying filmography at Musashino Art University in 2013, Itagaki made a doujinshi titled Beast Complex that she sold at the university. She self-published it under the pen name "Itagaki Hadome". It was a romance story about a wolf named Legoshi, who worked as a stylist assistant, and a rabbit named Haru. It had three volumes with three chapters each. She also made a short film adaptation of the series. The praise from her friends for the manga inspired her to become a mangaka. The doujinshi introduced characters and setting elements (such as a war resulting in the illegalization of meat and the creation of a black market to sell it) that would be reused in the 2016 series and Beastars. Otherwise, it is unrelated to the ongoing Beast Complex.
In 2015, Itagaki began to work on the new Beast Complex. She published the first stories of Beast Complex in Weekly Shonen Champion throughout 2016. It was originally intended to be a four volume limited series.
Itagaki made Beastars in response to her editor asking for a longer and more sustainable story. During Beastars' run, three more Beast Complex stories were published. After Beastars concluded, it was announced that Beast Complex would restart to expand on the world of Beastars.

## Publication

Stories 1-6 were published in Beast Complex volume 1. Stories 7-12 (and in the English version, story 14) were published in volume 2. Stories 13-19 were published in volume 3. Stories 20-23 were published in volume 4.

When the leader of the fox group asks her to buy them sodas, she tells them to ask the nearby group of lionesses instead. This prompts the leader to push the fox to the ground.

Seeing that her chameleon friend stayed invisible and idle instead of risking getting involved, she wonders if acting like the stereotypical fox will bring her happiness and safety the way acting like a stereotypical chameleon did for him. Instead, she throws the organized handouts out the window to protest the stereotyping of animals. The next day, the fox bullies want revenge after the fox's lion comment caused a misunderstanding that prompted the lionesses to beat up the foxes. The chameleon saves the fox by perfecting his camouflage and attacking the foxes, who run away believing that a poltergeist attacked them. |||||

| Sage, a snake nurse, is on night shift. He hears a crash from a room, and enters to see a mouse named Nectar who has wet his bed. Nectar is angry and insistent that he change his own sheets. Sage states that snakes have no shame or honor (as unlike other animals, they do not wear clothing and are so emotionless that they would flash their penises at other strangers), so he does not need to feel embarrassed around a snake. This calm and amuses Nectar. Nectar asks Sage to sleep with him since he can not sleep alone. The head nurse criticizes Sage for doing so, as sleeping with a snake is considered bad luck. Sage continues to take care of Nectar, learning that the 50-year-old mouse has terminal metastatic cancer. While sleeping together one night, Sage inadvertently wraps around Nectar, only stopping when a falling apple wakes the two up. Nectar states that he would have been okay with being strangled, as species with short life spans are not allowed to be euthanized. Sage begins crushing him more tightly, but instead leaves, shedding his skin. Another nurse visits Nectar in the morning, noting that shed snake skins are good luck and symbolize rebirth. Nectar vows to get better so he can see Sage again. |||||
