Tsuina Miura is a Japanese manga writer best known as the original creator of the series High-Rise Invasion. Miura’s career in the manga industry began with the series Ajin: Demi-Human, for which he provided the story concept and initial script. Ajin, illustrated by Gamon Sakurai, was first serialized in 2012. Miura’s involvement with the series concluded after the first volume, with Sakurai continuing the series as both writer and artist.

Miura’s most prominent and sustained work is High-Rise Invasion, which he created as the sole writer. The series was serialized online in DeNA’s Manga Box app from December 2013 to April 2019. The story, illustrated by Takahiro Oba, follows high school student Yuri Honjō, who becomes trapped in a bizarre world of interconnected skyscrapers and must survive against masked assailants. Kodansha compiled the series into twenty-one tankōbon volumes. A sequel manga, High-Rise Invasion Arrive, again written by Miura and illustrated by Oba, was serialized in Kodansha’s Magazine Pocket from July 2019 to April 2021 and collected into seven volumes.

In February 2021, an original net animation adaptation of High-Rise Invasion was released worldwide on Netflix. The twelve-episode series was produced by the animation studio Zero-G, with Miura credited as the original creator.

Miura’s work is characterized by high-concept survival scenarios that place ordinary individuals in extraordinary, often life-threatening situations. Both Ajin, which features an immortal human-like being, and High-Rise Invasion, which unfolds in a closed-off world of skyscrapers, center on protagonists navigating dangerous environments with distinct internal rules. These works have contributed to the survival-thriller genre within shōnen and seinen manga, with High-Rise Invasion in particular achieving international recognition following its Netflix adaptation.
