Dojinshi is like when you see your friend draw their own version of a cartoon or a video game character. It's like a fan-made comic book or a fan fiction story created by people who really like a particular anime or manga. These fan-made works are often made by artists who love the original characters, but want to create their own stories or scenes with them. These dojinshi usually aren't officially published or sold, but rather shared or traded between fans. Sometimes people even make their own anime or manga, which is called "original" work. People who make dojinshi often do it as a hobby, but they can also earn some money if they sell their work at conventions or online. Dojinshi is a way for fans to express their love for their favorite anime or manga and a creative outlet to make their own versions of their favorite stories.
