My Dearest Self with Malice Aforethought

Eiji, a college student longing for a relationship, wakes up one morning to find his life completely changed by the emergence of a dark alter-ego known as "The Killer." This psychological thriller follows the twisted bond between Eiji and Riku, a high school boy obsessed with true crime. Their connection deepens into codependency as they navigate a world where the line between watching a murder and committing one becomes dangerously thin.

Hajime Inoryū wrote the story while Shōta Itō provided the artwork, launching the series in Kodansha's Weekly Young Magazine on May 7, 2018. The creative team shifted the serialization to the Comic Days digital platform in August 2019 to finish the story without constraints. The run concluded in September 2020 after roughly 100 chapters collected into 11 tankōbon volumes.

Kodansha USA brought the English version to readers starting in February 2021. Critics praise the work for relying on dialogue and tension rather than action sequences. Fans often compare its exploration of split personalities and moral ambiguity to other dark mysteries like Lonely Deaths Lie Thick as Snow. [edit]
