Tomonori Inoue is a Japanese manga artist and writer known for creating the post-apocalyptic science fiction series Coppelion. He was born in 1978 and resides in Tokyo, Japan. Inoue began his professional career after winning the 58th Chiba Tetsuya Award in 2008 for his one-shot manga Helsing Kyoju no Omoide (The Memories of Professor Helsing), a prestigious recognition that helped launch his work in the industry.

Inoue is best recognized as the original creator of Coppelion, which he wrote and illustrated. The manga follows three genetically engineered high school girls who are immune to radiation and are sent into a contaminated, abandoned Tokyo to search for survivors. Coppelion was first serialized in Kodansha's Weekly Young Magazine in 2008 and later moved to Monthly Young Magazine, concluding in 2016 after twenty-six collected volumes. The series was adapted into a thirteen-episode anime television series produced by the studio GoHands, which aired in Japan from October to December 2013.

Beyond Coppelion, Inoue has created several other original manga series. From 2017 to 2021, he wrote and illustrated Candy & Cigarettes, an action series about an unlikely duo of hitmen, which was serialized in Young Magazine Third and later Monthly Young Magazine, spanning eleven volumes. His subsequent work includes Midsummer Survive, a five-volume series published from 2022 to 2023 on the Magazine Pocket digital platform. In 2024, he began serializing Sky Pirate Hack and the Steam Princess on the MAGCOMI platform.

Inoue's artistic identity is strongly associated with high-concept action and science fiction narratives, often set against dystopian or post-apocalyptic backdrops. His work is frequently classified within the seinen demographic, targeting adult male readers with mature themes and complex storytelling. He has cited influential manga artist Naoki Urasawa as an inspiration, and his storytelling also reflects a personal appreciation for American crime films and noir. Inoue serves as both writer and artist on his projects, and his significant contribution to the industry includes creating a manga that was adapted into an internationally distributed anime, with Coppelion being licensed for streaming and home video in North America by Viz Media. His manga are published in English and other languages by various international publishers.
