Origin
The green monster featured in Tonari no 801-chan has its origins in 801-chan (やおいちゃん), the real-life mascot of the Misono Bridge 801 shopping center in northern Kyoto, Japan. The mascot, resembling Kyoto's well-known Kamo eggplant, was designed in late 2005 by a student at Kyoto Seika University. The shopping center itself was named for its 800-meter length, adding one to represent future expansion. Since the numbers 8-0-1 can be read in Japanese as ya-o-i (yaoi), the mascot soon became an Internet phenomenon. This brought the mascot to the attention of Ajiko Kojima, a Japanese blogger who took the mascot and slightly altered its appearance, using it as a basis for use his new webcomic Tonari no 801-chan in April 2006.

Plot and characters
Tonari no 801-chan is narrated by Tibet (チベット), otherwise known as Tibe-kun (チベ君), a twenty-eight-year-old company employee and boyfriend to Yaoi, otherwise known as Yaoi-chan (801ちゃん). Yaoi, who also works in a company, is a twenty-two-year-old fujoshi, a female otaku who is a fan of anime and manga series featuring yaoi, or romantic relationships between men. Tibet, who is an otaku himself, initially met Yaoi over the Internet. When she obsesses over yaoi, a small green furry monster comes out of a zipper from her back as the manifestation of her obsession.

In Tonari no 801-chan: Fujoshiteki Kōkō Seikatsu, the story begins with the junior-high school student Rei Hoshino (星野 れい), a fujoshi who does not especially have an interest in the 3D aspect of life. One rainy day, however, she takes an interest in a high school student named Kei Akai (赤井 彗) and wants to get into the same high school as him. To that end, she enlists the help of her childhood friend Shōtarō Kamiyu (神湯 正太郎) who helps her study for the entrance examination, and diet so as to become a cuter girl. All goes according to plan, until a scheming girl going to the same school named Luna Kurotsuki (黒月 ルナ) makes it harder for Rei to get closer to Kei.
