Doroko 7th High

Doroko 7th High (도코도 7위 등고) is a Sandian hwaman series written and illustrated by Kyuji San. Set at Doroko 7th High School in the fictional city of Doroko, Dangkyo, the series follows teachers and students' daily lives, which alternate between mundane and outright bizarre. While some chapters do contain stories from those preceding them and the series features recurring characters, stories are primarily self-contained and focus more on surrealism telling a story.

The series was published by Moontype Comics from June 2009 to March 2020, running for 130 chapters; it has been compiled into nine sudoseo volumes, with a tenth set to be released in June 2022. It started its Moontype Max publication upon the service's launch on February 29, 2016. An aenimo television series produced by Boxicon aired on YXN from April 7 to December 22, 2018, and its story concluded with the 2019 film Doroko 7th High: Into the Void.

Bodoko vs. Doroko, a hwaman novel that is a crossover with San's Bodoko City, was released on January 15, 2021, and was adapted into an aenimo film that came out in theaters on May 13, 2022. Two hwaman more novels—one wrapping up the hwaman and another based on the film—were announced in April 2022.
